Some pointed humor

By Mathew Goldstein

Enjoy this popular video poking fun at religious believers by NonStampCollector.  It is absolutely OK to lampoon ridiculous beliefs and willful ignorance.  We are not showing respect for humanity by refusing to actively criticize unjustified beliefs or by refusing to actively advocate for civic equality for atheists.

Senator Mikulski sponsors medical quackery week

By Mathew Goldstein

As if we do not have enough problems due to a refusal of most Republicans to accept and follow the overall direction of the available empirical evidences when setting national policies, particularly in the House of Representatives, one of the senior Maryland Senate Democrats, Barbara Mikulski, decided to introduce a resolution designating the week of October 7 through October 13, 2013, as “Naturopathic Medicine Week” that applauds "the value of naturopathic medicine in providing safe, effective, and affordable health care."  Naturopaths claim to be holistic, which apparently means they believe that the natural body is joined to a supernatural soul and a non-physical mind and the three must be treated as a unit.  Naturopaths offer treatment at their offices and at spas where patients may reside for several weeks. Their offerings include fasting, "natural food" diets, vitamins, herbs, tissue minerals, homeopathic "remedies", cell salts, manipulation, massage, exercise, colonic enemas, acupuncture, Chinese medicine, natural childbirth, minor surgery, and applications of water, heat, cold, air, sunlight, and electricity.  Many of these methods are said to "detoxify" the body.

This encomium for medical quackery was passed by the Senate with unanimous consent on September 9.  Eleanor Norton sponsored a similar resolution in the House, but that resolution was not voted.  Seventeen U.S. states, and the District of Columbia (but not Maryland), allow people who are trained at an accredited school of naturopathic medicine in North America to use the designation ND or NMD, some states even license such people to write prescriptions for drugs.  If this resolution is typical of popular, bipartisan, middle of the road, moderation, then don't look for me there.  Here is Senator Mikulski's resolution:

Designating the week of October 7 through October 13, 2013, as ‘Naturopathic Medicine Week’ to recognize the value of naturopathic medicine in providing safe, effective, and affordable health care.
Whereas, in the United States, 75 percent of all health care spending is for the treatment of preventable chronic illnesses, including high blood pressure, which affects 68,000,000 people in the United States, and diabetes, which affects 26,000,000 people in the United States;
Whereas nearly two-thirds of adults in the United States are overweight or obese and, consequently, at risk for serious health conditions, such as high blood pressure, diabetes, cardiovascular disease, arthritis, and depression;
Whereas 70 percent of people in the United States experience physical or nonphysical symptoms of stress, which can contribute to chronic health conditions, such as high blood pressure, obesity, and diabetes;
Whereas the aforementioned health conditions are among the most preventable health conditions and are especially responsive to the preventive, whole-person approach favored by naturopathic medicine;
Whereas naturopathic medicine provides noninvasive, holistic treatments that support the inherent self-healing capacity of the human body and encourage self-responsibility in health care;
Whereas naturopathic medicine reduces health care costs because of its focus on patient-centered care, the prevention of chronic illnesses, and early intervention in the treatment of chronic illnesses;
Whereas naturopathic physicians attend 4-year, graduate level programs with rigorous admission requirements at institutions that are recognized by the Department of Education;
Whereas naturopathic physicians are especially skilled in treating chronic illnesses, such as diabetes, asthma, autoimmune disorders, and gastrointestinal disorders, because of their focus on whole-body medicine rather than symptom management;
Whereas naturopathic physicians are trained to serve as primary care physicians and can help redress the shortage of primary care providers in the United States;
Whereas naturopathic physicians are trained to refer patients to conventional physicians and specialists when necessary;
Whereas patients of naturopathic physicians report higher patient satisfaction and health improvement than patients of conventional medicine;
Whereas the profession of naturopathic medicine is dedicated to providing health care to underserved populations;
Whereas naturopathic medicine provides consumers in the United States with more choice in health care, in line with the increased use of a variety of integrative medical treatments; and
Whereas the Patient Protection and Affordable Care Act (Public Law 111-148; 124 Stat. 119) requires that insurers include and reimburse licensed health care providers, including naturopathic physicians, in health insurance plans: Now, therefore, be it
Resolved, That the Senate–
(1) designates the week of October 7 through October 13, 2013, as ‘Naturopathic Medicine Week’;
(2) recognizes the value of naturopathic medicine in providing safe, effective, and affordable health care; and
(3) encourages the people of the United States to learn about naturopathic medicine and the role that naturopathic physicians play in preventing chronic and debilitating illnesses and conditions.

When atheism is religion

Gary Berg-Cross recently commented on the question "is atheism a religion?".  He concluded that, while there is no one correct answer to what qualifies as a religion, a reasonable way to tackle this question is to look for various indicators of religion.  One is a reliance on faith as a way of knowing.  Another is the notion that there are concepts and judgements which are measured and defined by non-human entities.  More generally, there is the belief in some non-natural power.  This approach implies that theism is "a religion", but it is not.

A problem here is that atheism and theism are particular beliefs and a particular belief is not necessarily unique to a particular religion.  A religion has a name that is capitalized.  So asking this question about theism, or atheism, is a category error.  Instead, we can properly ask if theism, or atheism, is a religious belief. 

Gary's thoughts on how to address the question, so re-worded, are good.  The conclusion we reach is that individual atheists who think faith is a valid way of acquiring knowledge, who think there are concepts and judgements which are measured and defined by non-human entities, and the like, can be considered to be religious.  Otherwise, Bill Maher is correct.  Atheism, unlike theism, is usually not a religious belief.  It depends on how the atheism is held and the overall context of beliefs in which the atheism is embedded.

But does this answer really address the original question?  Why do some people seem to think this is a significant question? What difference does it make if atheism is deemed to be a religious belief or not?

One place where this question has significance is the law because the first amendment calls for no establishment of religion and free exercise of religion and the tax code gives special benefits to religious organizations.  So let's not beat around the bush and pretend that "is atheism a religion?" is a direct philosophical question.  It is really about those laws and their applicability.  What the people who are asking this question do not appear to fully appreciate is that nouns can have different meanings in legal contexts than they do in everyday contexts.  That is the case here.  The people who are asking this question are actually asking if the no establishment clause, the free exercise clause, the tax benefits, apply to atheists and atheist organizations.  Gary commented only very briefly on these questions in his article.

Let's tackle tax benefits first.  There is no proper justification for treating different beliefs differently in the tax code.  We can properly make distinctions on various other criteria, but not on the beliefs of citizens regarding the nature or existence of gods.  Ideally, our tax code would distinguish between profit and non-profit organizations, and between organizations that advocate for or against candidates in government elections and those that do not. The tax benefits that are unique to religious organizations, such as the tax return filing exemption and the parsonage exemption, are unfair and should be eliminated.  If an organization is religious or non-religious should be irrelevant to the IRS.   But for now, given that the tax code does make this distinction, atheists are fully justified in insisting that we are fully entitled to all of the same tax benefits as theists.  So in the tax law context, religion includes both theism and atheism.

In the non-establishment context it is important to recognize that the first amendment does not refer to "a religion", it refers to religion in the plural sense.  We can only identify what is religion in this plural sense by identifying the presence of, and the role of, a religious belief.  Furthermore, in a legal context, a partisan belief is always paired with its opposing belief.  We can either assent or dissent to a partisan belief, and there is no difference in the legal standing of assenting and dissenting.  So here again, since theism is a faith-based, religious belief, and atheism is the dissenting belief relative to theism, both theism and atheism are covered by the noun religion in the Establishment Clause.

The Establishment Clause is paired with the Free Exercise Clause, so atheism also has the same free exercise protections as theism in principle.  However, in practice, atheism makes few, if any, free exercise demands against secular laws.  Protecting free exercise will tend to favor assenting religious beliefs over the corresponding dissenting beliefs.  Free exercise protection should not be allowed to interfere with the health, general welfare, or civil rights freedoms of other citizens.  Therefore, free exercise should have lower priority than most other civil rights protections.  Free exercise should prevail over secular laws only when such accommodation of religious beliefs otherwise does no significant harm.

Religious privileging in Maryland law


Laws that accommodate religious beliefs are sometimes appropriate, and even necessary, to respect individual religious liberty.  Laws should make a reasonable effort to accommodate religious beliefs, even when the religious beliefs are themselves foolish and deserving of disrespect (as is often the case).  Legal accommodation of some peoples' religious beliefs becomes unreasonable religious privileging when it is not protecting free exercise or when it infringes upon other peoples' freedom, civic equality, health, or safety.  Maryland law, like most other state law, includes some religious privileging.  Following are some examples, this is not a comprehensive summary of all such laws in this state.

There are a number of provisions in Maryland that accommodate faith healing.  Faith healing is a good example of a foolish religious belief that arguably negatively impacts primarily the religious believer and thus is at least partially protected as a religious liberty.  But Maryland law sometimes goes further and grants parents the ability to deny prudent medical care for their children. 

Most notable in this category is a religious exemption from a law that requires pregnant women to be tested for syphilis when they first become pregnant and again during the final trimester.  About 50 percent of pregnant women with untreated early syphilis end up with a baby who's infected. That's compared to 1 to 2 percent of women who get treated (thanks to atheist and materialist medicine that some people mistakenly characterize as exhibiting a methodological naturalism bias). They may lose the baby in miscarriage, stillbirth, or soon after birth, or the baby may be born with severe neurological problems. Syphilis also increases the risk of preterm birth and intrauterine growth restriction. This religious exemption from syphilis testing of pregnant women in Maryland is unconscionable and should be eliminated.  Other examples of questionable religious privileging in Maryland law that undermines the welfare of innocent children are exemptions from hearing, eyesight, and lead poisoning screening and from vaccinations.

Clergy are partially exempted from reporting child abuse revelations to law enforcement and judicial authorities.  Maryland law also has a second provision that broadly exempts clergy from testifying as a witness in judicial hearings "... on any matter in relation to any confession or communication made to him in confidence by a person seeking his spiritual advice or consolation."  Parents should think twice before passing their children over to religious institutions in Maryland.

Article 37 of the Declaration of Rights in Maryland's constitution  permits "... a declaration of belief in the existence of God" mandate "... as a qualification for any office of profit or trust in this State".  The U.S. Supreme Court declared this provision of Maryland law to be a violation of the first and fourteenth amendments in 1961, however this law has still not been amended to comply with the federal constitution.  Oaths of office for the National Guard and the Maryland Defense Force include a "So help me God" appeal.  Article 10 of the Rules of Interpretation contradicts these oaths while still incorporating an appeal to a god as follows:

The form of judicial and all other oaths to be taken or administered in this State, and not prescribed by the Constitution, shall be as follows: “In the presence of Almighty God I do solemnly promise or declare”, etc. And it shall not be lawful to add to any oath the words “So help me God”, or any imprecatory words whatever.

Article 36 of the Declaration of Rights permits anyone who does not believe "... in the existence of God, and that under His dispensation such person will be held morally accountable for his acts, and be rewarded or punished therefor either in this world or in the world to come" to be involuntarily disqualified from serving as a juror or witness.  This Article was amended in 1970 but the amendment did nothing to eliminate this religious privileging.  Instead, the amendment endorsed government establishment of theism by adding this sentence:  "Nothing shall prohibit or require the making reference to belief in, reliance upon, or invoking the aid of God or a Supreme Being in any governmental or public document, proceeding, activity, ceremony, school, institution, or place."

The theistic Pledge of Allegiance must be recited in public schools.  There is an opt out provision for both students and teachers.  Laws like this make it difficult for people to keep their personal beliefs private.  And children in particular shouldn't be instructed by the state that theism is the more patriotic belief.

There are exemptions from sales and property taxes for religious organizations, including a parsonage exemption from property tax.  Another provision gives localities the option of refunding part or all of the property tax that religious organizations would otherwise be required to pay.  There are also regulation exemptions for religious organizations regarding cemeteries, obtaining a trader's license, and erecting advertisement signs.

The Guardian's atheist defender of ignorance and superstition

Andrew Brown of the Guardian newspaper denies that it makes any difference whether most people's beliefs about how our universe works, which he labels "our stories", are true or false.  In his recent article "Virginia Heffernan's creationism is wrong but makes good sense", he also argues that it makes "good sense" for people to give justifications for their factual beliefs that provide zero probability of establishing that their factual beliefs are true.  He argues that only some small minority of people who specialize in building useful things need to have some narrowly focused skills required for them to be productive.  Therefore, he argues, only those people need to be epistemologically and ontologically competent within only the confines of their expertise.  But is work time specialization really the only place and time epistemological and ontological competence is needed?  

If we imagine two different countries, one where all citizens are epistemologically and ontologically competent and one where, outside of their narrow areas of work time specialization, all people are epistemologically and ontologically incompetent, which country would you rather live in?  Which country would you prefer shared a border with your country?  After all, our conclusions about how are universe works, and how we go about reaching these conclusions, influences many of the other decisions we make, including the laws we favor, our lifestyles, what and who we accept or reject morally, who is our friend or enemy, whether we ourselves are reasonable or unreasonable, rational or irrational, etc.  

People who choose creationism over evolution, regardless of whether they do this because they find creationism aesthetically more pleasing, or morally uplifting, or meaningful, or any other such entirely inappropriate reason, are asserting that humans are not primates with a common ancestor with other apes.  This is a factual claim, and as such it is not merely a story, and it is not a choice we make like selecting a novel to read.  Factual claims are foundations upon which we construct our laws, our morality, our aesthetics, and our decisions generally, including daily decisions and important decisions impacting not only ourselves but others around us.  To say, as Andrew Brown does, that "they are the clash of two competing stories", and "it is a story which derives most of its power from the way that believers suppose that it is true", is to wrongly trivialize the basic task of making true/false judgements down to the level of picking a novel in a bookstore.

Have we become so accustomed to the fact that epistemological and ontological incompetence are widespread that we have become inured to it?  Do we prefer to scapegoat the rich, the politicians, the boss, the big corporations, particular other religions, for all problems because that is easier?  Is this why people who know better keep making bad excuses that such incompetency is OK as long as it is other people doing this, not me and not my children?  We are told people will forever be stupid so give up, we have no way to reliably make any true/false decisions so one method is as good as any other, one person's truth is another person's falsehood, the primary function of holding true/false beliefs is something other than accurately modeling reality, etc.  Yet some of the same people who argue thusly for denying or ignoring this problem also advocate for public policies which are themselves responses to the symptoms of this same problem.  This refusal to deal with the underlying source of the problems that they argue against thus carries with it a whiff of pusillanimity.

The reality is that, insofar as anything at all has importance, what we believe is true about how our universe works and how we justify our beliefs are also important.  These are actually fundamental.  The Enlightenment was a major positive achievement for humanity exactly because it was about humanity getting a better grip on reality from a commitment to better epistemology and ontology.  Andrew Brown's populist defense of post-modern relativism is lazy, it is bad excuses for bad epistemology and ontology, it is regressive and harmful Counter-Enlightment advocacy. Virginia Heffernan's creationism is not merely mistaken, it is also foolish, there is no good sense to be found there.

Ways of knowing

Theists tend to claim that by applying theological principles we can determine not only that a god really exists, but the actual identity of this real god.  They then argue that atheists fail to take theology seriously and thus fail to acknowledge the strong justifications for theism.  We atheists tend to think theists are wasting their time on chimeras because theological principles are incapable of discriminating between what is true and what is false about how our universe works.

We can divide questions about truth into at least three categories:  what could be true, what is true, what should be true. The what should be true category can be further subdivided into moral and aesthetic judgements. That which is good/beautiful should be true while that which is bad/ugly should not be true.

Atheists start with the could be true question, compare the could be scenarios against the data, which consists of the empirical evidences, and then conclude that the could be true scenario which is the best fit with the available data identifies what is true.  Theistic theology mostly either does not do this, or does this in a biased, incomplete manner.  This is because theistic theology instead tries to derive conclusions about what is true on the basis of combining what could be true with what should be true.  An example of this is Pascal's Wager which argues that we could be punished by a god who should exist for the purpose of imposing an after death reckoning for before death misbehavior.

Theists complain atheists are being too narrow and closed minded by rejecting this sort of reasoning from theological principles.  Yet we all have excellent reason to think that we cannot derive what is true conclusions from what should be true principles.  Everyone experiences conflicts throughout their lives between what should be true and what is true.  People should not become injured, should not become sick, should not forget things, should not lack food or shelter, should not die, etc.  So atheists are merely guilty of being consistent when they reject reaching any is true conclusions from should be true derived principles.

God exists and has a particular identity versus gods do not exist are competing statements asserting alternative contingent truths that separate our actual world from all the other worlds we might have imagined.  The only way to reliably evaluate such competing statements about how our universe works is empirically.   No judgement about good/bad or beautiful/ugly is involved.  Because moral and aesthetic statements entail these additional judgements they are arguably different kinds of truth, and we cannot reach conclusions for such should be statements only empirically.

Yet empirically determined conclusions about how our universe works are needed to properly anchor our moral and aesthetic judgements.  Our moral and aesthetic judgements are built on top of our empirically derived prior conclusions about how our universe works.  Our subsequent judgements regarding what is good/bad and beautiful/ugly are informed by our true/false conclusions.  People who build their true/false conclusions about how our universe works from their moral and aesthetic judgements (a.k.a. from theological principles), although often well-intentioned, are making a mistake, like a home builder constructing a house underneath its foundation.

Belief and English language deficiency

Many people have recognized that English vocabulary is sometimes deficient and some have tried to add words, usually without success.  For example, many of the world's languages do not have gender-specific pronouns. Others, however – particularly those which have a pervasive system of grammatical gender (or have historically had such a system, as with English) – have gender-specificity in certain of their pronouns, particularly personal pronouns of the third person.  Problems of usage arise in languages such as English, in contexts where a person of unspecified gender is being referred to, but the most natural available pronouns (he or she) are gender-specific.  Michael Newdow tried to encourage us to substitute re, rees, and erm for gender non-neutral he, his, and him.

There is a similar, but more subtle,  problem with the words belief and proof.  The word belief is broad, it encompasses both justified and non-justified beliefs.  The word proof is narrow, it designates an established fact.  The problem is that we lack a good noun for properly justified belief that falls short of proof.  

One symptom of this vocabulary deficiency is that some people overuse the word proof.  If you see a link to an article with a title like "proof of existence of god" or "disproof of existence of gods" the best course of action is likely to not click on that link.  Another result is that some people refuse to utilize the word belief on the grounds that they do not want to taint their well justified beliefs with the unjustified beliefs of the hoi polloi by sharing the same noun.

I do not know of any efforts to coin a new word that is synonymous with justified belief.  The obvious problem is that the same hoi polloi will misuse the new word much like they already misuse the word proof.  The goal of avoiding a "guilt by association" type of taint by utilizing a more obscure vocabulary also has a cost. Using a different word implies a different entity, but the entity itself is the same here. Belief is not the problem to be avoided. The problem is holding beliefs that are poorly justified.

There are some people who go so far as to claim that belief is the problem.  I strongly disagree.  A belief is what we have whenever the available evidences overall have a favored direction.  I keep encountering people who claim that atheism is about having no beliefs.  Yet I can no more not have a belief about the existence of gods than I can not have a belief about the existence of Leprechauns.  The evidences do speak on these existence questions, the evidences are not neutral, and therefore the corresponding belief follows. We can expect one set of evidences if those entities existed, and a different set of evidences if they do not exist.  

With an ultrasound we can detect pregnancy.  That is proof.  With Leprechauns, as with gods, as with the supernatural more generally, we can only infer. It is still proper to utilize the word proof in contexts where conclusions are inferred provided that there is a consensus of the experts that the conclusion is true. Without this usage restriction the word proof becomes too political and loses much of its meaning. There is a sense in which we arguably do have such a consensus -  scientists de-facto abandoned supernaturalism several centuries ago. Unfortunately many scientists are unwilling to acknowledge that this constitutes a consensus answer to this question.

Evidences can speak loudly by being consistent and pervasive, which is the case here. We do not need proof to have properly justified strong beliefs. Mind is an natural emergent property of particular physical configurations of matter-energy, matter-energy is not a supernatural product of a non-physical mind - so we believe.

Defining supernatural

A mutually exclusive, yes or no, binary type of decision can be simple to make.  For some decisions we can directly observe the physical presence or absence of something and reach a definitive conclusion.  But we often have no direct access to the answer and therefore we must infer a conclusion on a best overall fit with the available evidences basis.  The conclusion is now going to be a probabilistic estimate, and therefore will represent a location on a continuous line joining the two end points.  The binary, one or the other, proposition is thus converted into a continuum by the decision making process.

However, it is impractical to assign a particular probability number to our conclusion since we typically lack enough information to be that precise.  Fortunately, Baysian probability analysis is still viable with only three discrete outcomes:  Positive, neutral, and negative.  We can assign the evidences one of three values, 1, 0, and -1 so that we can accumulate evidences into a single sum.  Every evidence for the proposition adds to the total, every evidence against subtracts from the total.  Does this conversion of our proposition from its original binary form to a discrete line form indicate that our proposition is incoherent and meaningless?  No, this is merely the unavoidable outcome of the fact that we are not omnipresent and omniscient so we often need to retreat to approximate Bayesian probabilities to infer a conclusion.

Many propositions are not well defined.  For example, we may ask if there is intelligent life elsewhere in the universe.  We cannot even begin to reach an approximate probability estimate until we have a definition of intelligent life that includes a criteria which can be utilized for evaluating the evidences.  The criteria selected to clarify the proposition will often unavoidably be somewhat arbitrary.   Does this arbitrariness and ambiguity in the definition of a proposition indicate that the proposition itself is incoherent and meaningless?  Lets try to answer this by identifying a criteria for intelligent life.

Our relationship with our pets, for better or worse, is limited by our inability to converse with them.  So we can specify as a meaningful criteria for intelligent life the ability to symbolically communicate with an extensive vocabulary.  There is still ambiguity here about what qualifies as extensive, but since inferring on the evidences is an approximation anyway we are not likely to benefit much from a more precisely defined proposition. Inferring on the evidence can be a coherent and meaningful activity even when we lack a precisely defined proposition.

We may sometimes need more than one criteria for evidencing a particular proposition.  Furthermore, we may decide that each criteria by itself evidences for the proposition.  This results in a complex proposition.  When we apply the evidences we may find that according to one of the criteria the proposition is affirmed, but according to the other criteria the proposition is disconfirmed.  Does the possibility of a such a paradoxical result mean that all complex propositions are incoherent and meaningless?  Again, the answer is no.  The possibility of such a paradoxical result is merely the unavoidable outcome of combining inference with a complex proposition.  Nevertheless, we should try to avoid making the proposition more complex than is necessary to reduce the risk of a paradoxical outcome.

In their excellent essay "Does Science Presuppose Naturalism?" (the correct answer is no), philosophers Yonatan Fishman and Maartin Boudry propose a complex, three criteria definition of supernatural.  I think their definition is a good start, but is unnecessarily complex and too weak.  I am going to propose a simpler and more stringent definition using their proposal as a starting point.

I will drop the criteria that they label as (2), which is that the phenomena "exist outside the spatiotemporal realm of our universe".  Although this criteria is associated with the supernatural, I want to keep the proposition as simple as possible and this criteria is not essential.  I will then modify the criteria they label as (1) and reverse the order of the two remaining criteria. This results in the following two criteria for identifying supernatural phenomena:  (1) They suggest that reality is at bottom purposeful and mind-like, particularly in a sense that implies a central role for humanity and human affairs in the cosmic scheme and (2) they operate in ways that fundamentally violate our current scientific understanding of what is permissible within the constraints set by natural laws.

The first criteria is important because it enables us to distinguish natural laws from supernatural laws.  We need to be able to make this distinction to apply the second criteria.  The second criteria is important because it defines the scope of what is possible within the natural framework.  Many people greatly underestimate the capabilities of the laws of nature and as a result of this ignorance are overly dismissive of the viability of naturalism.

The existing natural laws are incomplete. Therefore the quality of residing outside the scope of natural law is an insufficient condition for identifying supernatural phenomena.  Natural phenomena occurring outside the incomplete natural law framework are to be expected.  This is why the criteria says that a fundamental violation of a natural law constraint must occur. 

These two criteria can be combined into a single criteria.  This results in the following definition of supernatural phenomena:  They suggest that reality is at bottom purposeful and mind-like, particularly in a sense that implies a central role for humanity and human affairs in the cosmic scheme, and they operate in ways that fundamentally violate our current scientific understanding of what is permissible within the constraints set by natural laws.  This requires an initial categorization of the existing scientific laws of the universe as being either natural or supernatural, which is done using the first half of the combined criteria.  A violation of at least one natural law is now a requisite indicator of supernatural phenomena, but is by itself insufficient.  Because we approach claims of supernaturalism skeptically, we will also require that the violation evince a mind-like, judgmental or supervised, purposefulness.

One common objection to any attempt to define supernaturalism is that the supernatural concept is always ruled out because it violates Occam's Razor.  But Occam's Razor is a rule of thumb focused on dropping superfluous adornments, its not a fundamental law for disregarding the direction of the evidences.  Another common objection is that all evidences favorable to supernaturalism should instead be interpreted as evidence of an advanced technology civilization trying to fool us.  This is a mirror image of the perspective of some theists that evidences favorable naturalism are really favorable for god.  Some people assert that supernaturalism entails unpredictability, undetectability, and similar attributes that place it outside the reach of evidences, rendering any attempt to evidence supernaturalism futile.   This is actually false, supernaturalism entails no such particular set of attributes (the previously referenced essay by Fishman and Boudry addresses this).

Supernaturalists are inclined to try to argue that the current scientific laws of the universe are themselves supernatural.  One argument that our laws are supernatural is the Fine Tuning argument.  Victor Stenger, among others, argues that the premises of the Fine Tuning argument are false.  But even if the Fine Tuning argument was valid, our current scientific laws predict a multiverse, and combining the Anthropic  Principle with a multiverse undermines the Fine Tuning argument.  Another argument that our laws are supernatural is the First Cause argument.  However, the consensus of cosmologists is that modern cosmology has no need for a non-natural first cause. It is difficult to avoid concluding that our universe overall is indifferent to humanity and to life more generally.  Even people who should know better nevertheless avoid this conclusion for psychological and psychology related political reasons (people prefer to believe that our universe is about us).

Merely accepting the possibility of supernaturalism being evidenced doesn't produce such evidence or otherwise render our universe any less naturalistic.  On the contrary, the fact that supernaturalism could be evidenced, but is not, is all the more reason to conclude that our universe is naturalistic.   As philosophical naturalists, we can and should be willing to acknowledge that if our universe did evidence supernaturalism then we should be supernaturalists.  Best fit with the evidences, despite its limitations, is the only viable method we have to accurately model our universe.  At the end of the day the goal of our beliefs about how the world works is to accurately model reality, not to reach any particular, fixed conclusion.

Ask Congress to hire humanist military chaplains

Atheists, agnostics, deists, humanists, freethinkers, and others identifying as nontheists serve honorably within our nation’s military. Chaplains should support nontheistic service members with the same enthusiasm, resources, and services that they provide for theistic service members.  But the reality is that at least some religious chaplains are ill equipped to handle the problems of nontheistic soldiers.  The House of Representatives will be voting this Thursday on an amendment that proposes to open the military chaplaincy to humanists.  Send an email to your Representative today from the Secular Coalition of America Action Alert page.

Why everyone should be an atheist

We start from scratch, from the perspective that we will give both possibilities, atheistic naturalism and theistic supernaturalism, equal opportunity to be adopted.  We can define supernaturalism as immaterial willful agency and/or immaterial mind, or god.  We know nothing and we are born into a universe.  What would we experience in a universe where we would be properly justified to be theists, and how does that universe compare to our universe?

We need an unbiased criteria to decide.  The bottom line is practical success versus failure, so that is the criteria. Success is whatever works to meet our needs and desires.  We need things like food, health, shelter, we desire things like travel and knowledge.  So what delivers our needs and desires?

The answer could be divine revelation.  By studying the holy texts, adopting the specified beliefs, worshipping, praying, following the rituals, obeying the laws, as revealed to us by deity, we receive food, health, shelter, transportation, and knowledge.  In other words, by practicing methodological supernaturalism we are successful.  Given a choice of what to believe, we follow the available evidences and become theists because the universe evidences supernaturalism.  However, in our universe, agriculture, medicine, housing, and transportation are human built and maintained products of human acquired knowledge, our knowledge is built exclusively on methodological naturalism, and the content of our knowledge is also naturalistic.  Therefore, when we follow the available evidences we become atheists because our universe evidences naturalism.

Some theists will probably object to this argument for atheism by saying it is bad theology.  Should we respect this objection?  If we are committed to holding beliefs that accurately model how the universe works then we should disregard this objection.  Success, not self-referencing ideology, must be our guide because success is the most plausibly unbiased criteria available to us, it is the way that our universe itself communicates to us regarding how our universe works.  Lacking omniscience we lack certainty that our conclusion is correct.  But such unavoidable uncertainty makes no difference.  We are rationally obliged to adopt the conclusion favored by a pervasive and unchallenged track record of success.

Memorial service in Boston excludes atheists

The memorial service for the victims of the Boston marathon bombings began on April 18 at 11:00 AM ET in the Cathedral of the Holy Cross. Boston Mayor Tom Menino, Massachusetts Governor Deval Patrick, and clergy representing different religious denominations across the city took to the podium. President Barack Obama offered the final reflection of the service and Cardinal Sean O'Malley concluded with a closing blessing. The memorial was broadcast nationally on television, the radio, and the Internet. The published "interfaith" program features the seal of the state of Massachusetts. The state sponsored service was mostly conducted by and for theists, with most speakers making obligatory references to their God. A notable exception was Governor Deval Patrick, whose speech was inclusive. It could have been more inclusive.

Celeste Corcoran of Lowell, Massachusetts, who lost both her legs at the knees in one of the bomb blasts and her 18 year-old daughter, Sydney, who suffered severe injuries as a result of being hit by shrapnel, were part of the humanist community in the greater Boston area. According to Greg Epstein, the Humanist Chaplain at Harvard University, both the White House and the staff of the Governor's office who were organizing the event were contacted in advance repeatedly with requests to include the non-theist community in the memorial service. "All they had to do was say one word, or allow one official guest, and they didn't", said Epstein, "...we [the Secular Coalition for America] contacted them [the governor's staff] every hour on the hour".

Herman Philipse's critique of religious reason

In his book God in the Age of Science? A critique of religious reason, Herman Philipse tackles a question at the core of philosophy of religion: Are there good reasons for thinking that some specific subset of religious beliefs makes sense and is true? In particular, is the defense of bare theism by philosopher Richard Swinburne, which relies on Bayesian estimates of probabilities, successful? This book is too academic, and too expensive, to become a best seller, but the overall argument is easy to follow and understand.

Philipse reaches three conclusions that support atheism. First, traditional notions of gods are self-contradictory and dependent on analogy and metaphor, therefore it is an ill-defined concept. Second, theism lacks predictive power concerning existing evidence, undermining the integrity of Bayesian arguments deployed in its defense. Furthermore, the truth of theism is improbable given the scientific background knowledge concerning the dependence of mental life on brain processes. Third, the empirical arguments against theism outweigh the arguments that support, so insofar as Bayesian cumulative case strategy does work we should conclude that atheism is more probable than theism.

Philipse categorizes arguments for theism according to which of three possible pairs of opposing strategic decisions are utilized. We start with deciding whether theism is a cognitive, and thus a factual, claim. If it is non-cognitive, an approach favored by people such as Wittgenstein, then it isn't asserting anything of substance that merits being taken seriously, so that is a self-defeating strategy for defending theism.

Having selected the cognitive option, we next need to decide whether or not reasons and evidences are needed to justify theism. Alvin Plantinga is cited as an example of someone who defends the notion that no further reasons are needed for (his particular) religious beliefs to be warranted. However, theism, like all other existence beliefs, is reasonable or warranted only when there are good positive reasons to justify the conclusion that the belief is true.

Having concluded that we need good positive reasons to justify theism, our final decision is selecting the methods that provide us with good positive reasons. Either we employ the same methods that we generally rely on when investigating a factual hypothesis of existence, or we don't. If we opt to employ different methods then a public and persuasive validation is lacking, resulting in a credibility problem for theism. The outcome for theism is just as bad when we turn to the reliable methods of skeptical empiricism which refute and disconfirm theism. Page 343 summarizes the conclusion in one sentence: "Either religious believers have not succeeded in providing a meaningful characterization of their god(s), or the existence of this god or these gods is improbable given our scientific and scholarly background knowledge."

Herman Philipse on conflict between science and religion

The Center for Inquiry of Low Countries held a conference on secularism in May 2008 in the Netherlands. One of the speakers was Herman Philipse. Herman Philipse is a professor of philosophy at Utrecht University. In this video we can see him briefly arguing for the thesis that religion as a source of knowledge is a failure and therefore we should all be atheists. Is there a warfare between science and religion?

Life ends frequently, but began maybe only once

At this year's Conservative Political Action Conference, Marco Rubio expressed a commonly held view among conservative Republicans that secularists are being inconsistent and ideological, rather than factual, regarding abortion: "The people who are actually closed-minded in American politics are the people who love to preach about the certainty of science with regards to our climate but ignore the absolute fact that science has proven that life begins at conception..." This is completely false, and it is a good example of why secularists tend to think that many of the conservatives religionists in the Republican party are not particularly intelligent and that their leadership, pandering to their base, are not particularly honest. And this is just one of many such examples.

When asked for the age of the universe, a very simple question with a single, straightforward correct answer (13.77 billion years ± 0.059 billion years), Marco Rubio (like Rand Paul and other Republicans seeking a national audience) punted, saying: “I’m not a scientist, man. I can tell you what recorded history says, I can tell you what the Bible says, but I think that’s a dispute amongst theologians”. What the bible says? A dispute among theologians? The age of the universe is an astrophysics question. Seeking the answer from the bible or from theologians is just as illogical and unreasonable as reading the bible, instead of the manufacturer's manuals, for instructions to maintain an aircraft, or hiring theologians instead of pilots to fly an aircraft.

So when does life begin? It may help to clarify this question by first addressing the related question "when does life end?". Life ends frequently, everytime an individual living creature dies. Everytime a bacteria, or an archaea, or a dust mite dies, everytime a single sperm or an unfertilized egg dies, a life ends.

It may seem intuitively logical for some people, given that we all experience our lives as individuals, to think that human life begins as human life ends, with each individual. But this intuition is wrong. Science tells us that life successfully began at least once, at least three billion years ago. Life may also have independently begun elsewhere in the universe, it may have started unsuccessfully multiple times within our solar system, we don't know. What we do know is that since life successfully got started billions of years ago, it has been continuous, and all life on earth may have a single, last common ancestor.

What about the role of conception? Conception is one of multiple requisite milestones in the continuous cycle of human life. Much of life reproduces without a conception event. Presumably Marco Rubio knows this, and he was talking only about human life. But human life evolved from single celled life, and a conception event doesn't change the overall context that all life, including individual human life, participates in the same continuous cycle of life.

So no, we secularists, or we liberals, who favor legalized abortion, are not being inconsistent, are not ideologically ignoring the evidence, are not being hypocritical, are not guilty of a double standard, for refusing to acknowledge the so called "absolute fact that science has proven that life begins at conception". Life is an ongoing, continuous process, it does not begin at conception. There is no scientifically established fact that human life begins at conception. It is the conservatives who keep asserting otherwise in the name of science that are being anti-scientific. They are the ones, after all, who advocate obtaining answers to scientific questions by reading the bible and asking theologians.

So help me God "history" from nothing

People sometimes ask me who was behind the false claim that George Washington appended "so help me god" to his first presidential inaugural oath. Was it David Barton? The answer is that there were multiple people who shared responsibility for promoting this fiction into a fact. It happened over time with a number of milestones.

It began with four biographies of George Washington. The first biography to be published was written by the Reverend Rufus Wilmot Griswold. Published in 1854, 65 years after the inauguration, it is titled "The republican court; or, American society in the days of Washington". This book mixes historical fact with apocryphal legend until one is indistinguishable from the other. His friends knew Griswold to be a consummate liar and had a saying: "Is that a Griswold or a fact?" As a literary editor he often pirated entire works even while advocating for international copyright law that would have rendered his own actions illegal. He wrote a short biography of Edgar Allan Poe that included letters which he had forged for the purpose of slandering the deceased poet. If there is a dishonest David Barton like character in this tale then it is Griswold.

If Griswold's book was the only book claiming that George Washington said "so help me God" then it is doubtful that many 20th century historians would be asserting this also. Enter Washington Irving, the first American to earn a living from writing popular books of fiction and a popular biography of Christopher Columbus. His final book was a five volume biography of George Washington published in 1857. There are no citations and it doesn't comply with modern standards of scholarship, but it is still read. Of the four George Washington biographies, this is the one that was most influential in promoting the falsehood about George Washington's inaugural. Washington Irving was also the only one of the four authors who was alive during the inauguration, and he may have been in the crowd outside of Federal Hall during the inaugural ceremony. At that time he was six years old. Griswold places him at the corner of New street and Wall street. Washington Irving never claimed to have heard the oath recitation. For his biography he copied someone else's first hand account of the inaugural ceremony with some modifications. One of those modifications was to depict George Washington saying "so help me God" immediately after the oath recitation.

John Frederick Schroeder was an Episcopalian minister whose biography of George Washington, titled Life and Times of Washington, was also published in 1857. He died before the book was published, and Griswold had a hand in completing Schroeder's book. Memoirs of Washington, by Caroline Matilda Kirkland, was also published in 1857. Kirkland mimicked Griswold and wrote, "..., he [Washington] was observed to say audibly, 'I swear!' adding, with closed eyes, as if to collect all his being into the momentous act - 'So help me God!'. Schroeder and Kirkland mingled with Griswold and Irving in the same New York city literary circles. Afterwards, many books and articles continued to claim that George Washington said SHMG.

The next milestone is the civil war. To distinguish themselves from the Unionists whose federal oath of office was godless, the Confederates advertised that Jefferson Davis included those four words when reciting his oath in 1861. The Unionists, not wanting to be outflanked by the Confederates, included this phrase in their revised federal oath of office in 1862. This phrase remains in the federal oath of office to this day.

The third milestone occurred with the assassination of president James Garfield. Chief Justice Waite led Vice President Chester Arthur in reciting the words of the presidential oath. After the oath recitation was completed, the new president, on his own initiative (without prompting from the Chief Justice), added "I will, so help me God", copying the words from the oath he had taken months earlier when being sworn in as Vice President. This was widely publicized in the newspapers.

The fourth milestone was the loudspeaker and the radio. Loudspeakers were introduced in 1921, radios in 1925. After radio became a home appliance, the inaugural oath could be heard by people across the country, whereas before only a few privileged people standing close to where the president stood could overhear the oath. By now, many people had read one of the many accounts of George Washington's first inauguration claiming that he completed his oath recitation with an appeal for divine help. Every Chief Justice during every presidential inaugural since 1933 has, while leading the oath recitation, prompted the president to say "so help me God". This is odd given that these four words are not part of the oath and the president therefore has no obligation to say them.

What appears to be happening is this: Many Americans, possibly a majority, don't know that the constitutional oath for the president is godless (and that the original federal oath of office was also godless). Some people would be upset to learn that the constitution was written to accommodate an atheist being elected president. Some people would be even more upset if they actually witnessed a president elect not saying those four words upon becoming president. To avoid disabusing these people of their false conviction that the oath is monotheistic, or of their prejudice that an oath must be monotheistic to be fully legitimate, the Chief Justice always prompts for these four words while administering the oath to the president elect.

The fifth milestone was another George Washington biography. George Washington, a Biography, by Douglas Southhall Freeman, was published in multiple volumes from 1948-1957. Volume 6, Ch. Viii, "Inauguration Day is not without Clouds, April 30, 1789", page 192 has a paragraph describing the oath recitation that depicts George Washington completing his oath with the four word appeal for divine help. Unlike the first four biographies, this is a scholarly book written by a highly respected historian. Accordingly, there is a citation to a primary source document, in this case a letter written by Tobias Lear, George Washington's personal secretary, to George Augustine Washington, George Washington's nephew who was at that time managing the affairs of Washington's Mt. Vernon Estate. This letter was in the rare documents vault at Duke University. The first three pages of this letter were published in 1987 in "The Papers of George Washington, Presidential Series," vol 2:154-155. But it was page four of this letter that described the oath recitation and apparently no one had previously tried to verify that this letter actually supported the claim that George Washington appended those four words. Here it is, take a look: Lear's letter of May 3, 1789 to George A. Washington. No SHMG.

More recently, another false historical fact was layered upon the first one. This is the additional claim that every president followed the precedent set by George Washington and likewise appended "so help me God" to their inaugural oath of office. No less than the Senate Historical Office itself, despite our complaints, persisted for years in promoting this whopper falsehood with a video titled "so help me God" on the Joint Congressional Committee on Inaugural Affairs website. David Barton was probably among those endorsing this false "fact".

Religious practices are rooted in doctrine

In his March 1 article in the Huffington Post titled "Faith Isn't Irrational, But Beliefs May Be", Peter Georgescu, Chairman Emeritus of Young & Rubicam Inc., citing Karen Armstrong's arguments, defends Christianity in particular, and religion more generally, as follows: "Belief in Christ has little to do with intellectual agreement on some ostensibly factual truth about God." Similarly he says "The major Western monotheisms all concerned themselves primarily with practice, the doing of religion, rather than doctrine. " For him "A good Jew observed the Sabbath and remained committed to the Law and the ritual year; and a good Christian embodied the Sermon on the Mount by caring for the marginalized, promoting compassion and peace, and sharing God's love." It should be impossible for intelligent people to buy into this argument for a number of reasons.

First of all, contrary to what Armstrong, or in this case Georgescu, asserts, religion has historically been doctrinal. People throughout history killed each other in wars fought over conflicting religious beliefs because they took the competing factual claims of their religions literally. The book of John, for example, self-claims to be a factual, eyewitness, historical account of real, historical events by one of the actual disciples (21:24 This is the disciple who testifies about these things and has written these things, and we know that his testimony is true). The Quran and the Hebrew Tanakh, like the Christian bible, are preoccupied with asserting factual, historical events, complete with the names of real locations, governments, and people. Throughout history even the most intellectual religionists claimed to extract divinely revealed facts about how the world works from their holy book. For instance, Thomas Aquinas believed that God created the body of the first human, Adam, from the "slime of the Earth" and God created the first female, Eve, immediately thereafter using Adam's rib. Similarly, he believed that God produced the fish and birds from water. Thomas Aquinas cited the book of Genesis as the source for this factual knowledge.

Secondly, the practice of religion is itself rooted in religious factual claims. It is only on the basis of endorsing the particular factual claims of a religion as being true that people can credibly justify a commitment to observing the commandments and the resulting practices of the religion on an ongoing, daily basis. According to Christianity, for example, the historical, factual, resurrection of Jesus Christ opens the way to eternal life and glory for those who believe. Anyone who claims that the resurrection is fictional is contradicting a basic premise of Christianity that is needed to justify the practice of Christianity. The religious practices of Judaism and Islam are similarly justified by, and thus dependent upon, their distinct factual claims.

Atheists don't keep kosher and observe the Sabbath because there is no proper justification for doing so. We recognize the Sermon on the Mount is seriously flawed, giving some bad advice, contradicting itself, a hodgepodge lacking any underlying theme. It characterizes poverty as a virtue and wealth as a vice, asserts that there is an afterlife, calls for lending on request without regard to need or likelihood of repayment, and the like, which are rationally unjustified. A faith that obscures or denies these flaws is a faith in conflict with the empirical evidences regarding what is true and false.

Thirdly, many of the practices of different religions are mutually compatible, while the factual beliefs associated with those practices are often mutually incompatible. Accordingly, if religion was about practice only, and not about beliefs, then it follows that there is a lack of good justification for segregating practices by religion. If religious people frequently combined the practices that originated from different religious beliefs then we would at least have some evidence that the incompatible factual claims unique to each religion don't matter to them. Yet Christians rarely commit to the religious practices of Jews and Muslims, Jews don't commit to the practices of Christians and Muslims, and Muslims don't commit to the practices of Jews and Christians.

Reading arguments like those of Karen Armstrong, and of her fans, that religion has nothing to do with beliefs regarding what is factually true or false is like reading an argument that joining a political party is properly motivated only by that political party's practices, which are devoid of factual content, and that the political party's policy statements and orientations are not rooted in any claims about what is factually true or false. That otherwise intelligent people publicly make such a superficial argument is a testament to how desperate some people are to defend religion and of the weakness of the mindless religious identity that they cling to. Liberal religionists tend to deny that their beliefs are rooted in any facts about how the world works, conservative religionists prefer to buttress their beliefs with facts about how the world works that are counter-evidenced. Underlying this disparity in approach is a single common mistake: They are both failing to take an evidence first approach to justifying their beliefs.

A philosopher who promotes critical thinking

Here is an audio excerpt of the "Critical Thinking Crash Course" presentation by Dr. Peter Boghossian to the Agnostics and Atheists at Intel on May 11 of last year. Peter Boghossian's blunt criticism of faith based reasoning while working as a professor of philosophy at Portland State University has sometimes been deemed to be too judgmental to comply with academic norms by some of his peers at PSU. But Peter Boghossian recognizes that knowledge cannot be divorced from judgement and he is not deterred. He presses on with his "street epistmology" of trying to encourage critical thinking among his students and any audience that will finance his travel ($1500).

“I’m advocating that there are certain processes that will more closely help [people] to align their beliefs with reality; faith is an unreliable process. It will not help you come to reliable conclusions. It will decrease the possibility you come to that,” Boghossian says. He says of his critics: "“Here’s what they don’t understand: Ideas do not require dignity. People require dignity. There’s a difference between attacking an idea and attacking a person. Attacks on faith are not like attacks on race." We need more advocates of critical thinking like Peter Boghossian. Critical thinking requires restraint and discipline, it is about applying constraints. But many people prefer to be free of such constraints and just believe according to their fancy, so it needs to be taught and learned.

Morality not dependent on behavior being unpredictable

In the monthly WASH bulletin there is another article on free will titled "Free will and Hell" written by he coordinator of the Baltimore chapter. As before, it describes Daniel Dennett's perspectives as he discussed them at John Hopkins University. I will spare the readers a discussion of every one of my disagreements and agreements with that article in detail. Instead I will briefly comment on the start of the third paragraph which follows:

"A concept of free will is necessary for morality because no individual can predict exactly what another will do. Many human actions are based on internal motivations or patterns of neurons that can't be observed. The actions appear random to anyone who doesn't know the person. The behavior is not free in the sense of being undetermined by physical causes, but it is free in the sense of being unpredictable by a casual observer."

We are free provided that we are not compelled to act according to someone else's dictate. This distinction between self-originating action and actions that are intended to comply with a behavioral demand of someone else is important. Even to the extent our behavior may be predictable it is still free provided it is an action that is self-selected. It is not true that we are free because our actions are not predictable.

Anything that is complex can be difficult to predict, not necessarily because it isn't predictable in principle, but because we would need to know about many physical properties and interactions that would require technology that we don't have. Also, the process of measuring things on the small scale can disturb the activity that is being measured. Predictability tends to diminish with time, so even with future technology we may be able to predict a given behavioral choice only a second or less in advance. That future is almost here as neuroscientists have demonstrated that they can translate information obtained from monitoring neurons into behavioral predictions, albeit in restricted contexts and without complete accuracy. But even to the extent that we could reliably predict behaviors, those predicted behaviors would still be free behaviors.

I also disagree that behaviors being unpredictable equates with free will or that either is necessary for morality. Free will is about minds having agency that is free from materialistic cause and effect constraints. Morality is about actions or inactions that harm or constrain people and our environment. They are different concepts and morality is not dependent on behaviors being unpredictable.

Evidences can go both ways, no exception for gods.

Over a year ago, Michael Shermer, founding publisher of Skeptic magazine and the monthly "Skeptic" columnist for Scientific American, wrote a short article on skeptic blog titled ARE YOU AN ATHEIST OR AGNOSTIC? To his credit, he has openly identified himself as an atheist for many years, although he prefers to label himself as a skeptic. However, his initial argument for atheism is actually a weaker argument for non-theism. Furthermore, he first claims that it is not possible to have positive evidence for atheism and then he contradicts himself by claiming that we have positive evidence for atheism.

Michael Shermer points out that "we act as if there is a God or as if there is no God, so by default we must make a choice, if not intellectually then at least behaviorally." This is true in the sense that we must choose to worship, pray to, or otherwise obey the instructions allegedly provided by, a God. But people can believe that God has not given them instructions, isn't asking or seeking to be worshipped, doesn't respond to prayers, etc. Such people believe in a non-personal God, so they aren't theists. They are deists. Michael Shermer defines such deists as atheists because they live their life as if there is no God. It is more accurate to call them non-theists.

Michael Shermer then emphasizes that it is untenable to assert that a God does not exist. He says, parenthetically, that "you cannot prove a negative." This is false. Sure, it is difficult to "prove" that something doesn't exist, but that doesn't mean that evidence never can speak against an existence claim. We have evidences that flying pigs and talking donkeys do not exist, never have existed, and never will exist. To believe that such creatures exist is unreasonable precisely because they are counter evidenced.

He then says that, as skeptics, we should "not believe a knowledge claim until sufficient evidence is presented." I agree with Michael Shermer here that skepticism is the correct approach. But he is wrong to assert that atheism is tenable only when it "withholds belief in God for lack of evidence." His argument that the only choices are between an untenable certainty that there is no God and a tenable withholding of belief in a God creates a false dichotomy. A tenable third choice is to actively believe that there are no gods on the grounds that the weight of the overall available evidences favors the no God conclusion. Michael Shermer makes bad excuses for refusing to even consider this possibility. It should be obvious that we all actively believe that many existence claims asserted by many different people are false, which is why we call them fictions.

What isn't so obvious is why God existence claims can only have supporting evidences when other existence claims can also have opposing evidences. Michael Shermer surely knows enough about biology, physics, and sociology to know that our universe appears to operate on a strictly materialistic basis, yet apparently he won't admit that this is evidence against an immaterial mind and immaterial, willful agent. Or maybe he is unwilling to acknowledge that evidence against immaterial minds and willful agents is evidence against gods? Does anyone believe in an entirely materialistic God that operates entirely within the laws of physics? No one should because such a naturalistic "God" is completely superfluous.

Note that Michael Shermer could also argue that it is untenable to assert that a God does exist, and that "you cannot prove a positive." Whatever evidence there is for a god, Michael Shermer the skeptic could point out that this same evidence could be interpreted as being produced by aliens with advanced technology who are intent on fooling us. Lots of people get diverted by this misdirected notion that we require proof to properly justify our beliefs (even though in practice these same people hold many beliefs without this unreasonable and impossible "proof" standard). They argue that we cannot prove one way, or the other way, or both ways, and then they insist that we must stop there and withhold judgement. But it makes no sense to stop there without evaluating what, if anything, the evidences say, since evidences can favor one conclusion over others. There is a word for this "there can be no proof, end of story" stance: It is a cop-out.

Michael Shermer concludes his argument by saying: "I do not know that there is no God, but I do not believe in God, and have good reasons to think that the concept of God is socially and psychologically constructed." This then becomes an inducement to read his book titled The Believing Brain in which he presents "extensive evidence to demonstrate quite positively that humans created gods and not vice versa." So Michael Shermer does assert that there are empirical evidences that gods are fictions after all. He isn't merely withholding belief for lack of evidence, he is saying there are positive evidences against. So why didn't he acknowledge from the beginning that the evidences can go either way and there are evidences against?

I think Shermer is an atheist rather than a non-theist. But he isn’t allowing his atheism to shine through. He is hiding his atheism behind his skepticism and a non-theistic ‘I don’t believe’ stance. Maybe he lacks the self-confidence to defend a more assertive “I believe there are no gods” stance. Atheism is 100% defensible on a straightforward weight of the overall evidence foundation.
