Epistemology 101 Part 2: Truth Claims



Epistemology: [mass noun] (Philosophy) the theory of knowledge, especially with regard to its methods, validity, and scope, and the distinction between justified belief and opinion.

As a Matter of Fact: The Nature of Truth Claims
Debate usually consists of two parts. First there is the Dialectic, or the argument in which the debater tries to vindicate (or validate) their claims, and then there is Rhetoric, or the part of the debate in which the debater attempts to compel you to agree with them. The goal is to get others to agree with you that your truth-claim is also a fact-claim. This is true of the religious debate as well. “Language, including religious language, is partly about propositions, fact-claims, or what we might call “truth-talk”,” affirms the anthropologist David Eller (Eller 2007, p.57).

When it comes to truth claims, or “truth-talk” (i.e., claims which are talked about as being true) the burden of proof always falls on the person making the claim. If for example I said I had a unicorn in my house, it would be up to me to prove to you that this statement was true. If I could not prove to you that what I claimed was indeed the case then my argument would be meaningless. In other words, if I could not offer any evidence to prove to you that I had a unicorn in my house then you would not be obligated to believe my claim. The truth claim would be falsified by my failure to provide any empirical basis for sustaining a belief in the unicorn.

Now supposing I brought pictures of the unicorn standing next to my study desk, although this constitutes as evidence in support of my claim it does nothing to make the claim believable let alone truthful. Alone this form of evidence would be pretty weak, after all, I could have used Adobe Photoshop to take a picture of a horse, add in a fake replica of a horn, and paint it up just the way I liked before offering it to you. Even as this evidence would be fraudulent, again, the burden of proof lies on me to prove beyond a reason of a doubt that I have a unicorn. Pictures alone may not convince you, and so you’d have every right to remain skeptical. Therefore, when trying to affirm a truth claim as factual—you need to do more than provide the bare minimum evidence required for believability, you need to establish a context in which the claim is not only believable but verifiable. If the claims I am making cannot be checked and confirmed, then it’s a good bet that they are fallacious claims, and that my unicorn exists only as a figment of my imagination.

Now suppose I made a more audacious claim than that. Suppose that I have dodged the burden of proof by making my unicorn an invisible pink unicorn. Obviously this doesn’t help my case for two reasons. First, instead of offering any tangible evidence I have made the claim even more tenuous by placing it even further out of the realm of empirical support. Any real chance of confirmation just became unlikely, because an invisible pink unicorn is an imaginary entity, and so the claim that such a thing exists becomes a metaphysical claim. Secondly, this makes any discussion about the nature of my invisible pink unicorn an ontological discussion designated to the realm of theology, and as we saw in the previous article, ontological discussions fail the epistemic standard of what it means to be reasonably and rationally true.

Epistemically Viable: Rational vs. Irrational Belief
Epistemology of belief does not end with mere facts and proofs, however. Any truth claim is, in essence, a prediction. If the meteorologist on the evening news claims it will rain tomorrow he is basically making a prediction—usually based off of scientific data about global climate and weather change. In this sense a truth claim is not only something which can be believed, but it is also something that is making a prediction, i.e. that at the appointed time that we discover this truth the prediction will be fulfilled. Therefore, tomorrow if it should rain as predicted by the news weatherman then the claim is epistemically valid. The prediction was accurate.

However, if a claim makes no valid prediction (including predictions which cannot be counted due to the fact that they are metaphysical in nature and cannot be checked) then the belief in such a claim can never be a matter of factual truthfulness, but rather, a matter of the will to believe. The epistemologist Hamid Vahid puts it more clearly, stating, “In the betting context, however, the pertinent sense of “rationality” or “reasonability” is epistemic since the winning side is determined on the basis of the truth of its prediction.” (Vahid 2008, p.137)

Thus when someone says they believe something is true, we will be more likely to find the claim reasonable and rational if the truth of its prediction can be confirmed. If the truth of its prediction cannot be confirmed then it is more likely to be a false or baseless claim.

As human beings our minds have been conditioned by experience and interaction with the natural world. Therefore we either believe a proposition based on good evidence or else we reject it when the evidence is lacking. As the Stanford University philosopher Michael Bratman reminds us, “Reasonable belief is, in an important way, context-independent, at any one time a reasonable agent normally either believes something (to the degree n) or does not believe it (to that degree). She does not at the same time believe p is relative to one context but not relative to another.” (Bratman 1999, p.123)

The claim that “God exists” or that “God is real” is not epistemically viable as such a claim is not context-dependent, rather belief is context-independent (I'll explain more on this shortly). What this means is that it can never be factually true from an epistemological point of view—at least not without empirical support. The claim that God is real is true in the sense that the believer holds the belief of God’s existence as a matter of truth, but these reasons are rarely ever good and so usually fall into the designation of faith. In order for the claim “God exists” to be factually true it would need confirmation, and only after the prediction has been vindicated could the statement gain epistemic credibility as a truth claim.

Just to clarify, context-dependent and context-independent are cognitive science terms related to recognition memory. Recognition memory can be subdivided into two components: recollection and familiarity, sometimes referred to as "remembering" and "knowing." Recollection involves remembering in detail a particular stimulus, including the context in which it was previously experienced. In contrast, familiarity only requires knowledge of the stimulus’s features – the basic realization that one has encountered the stimulus before. Thus, the fundamental distinction between the two processes is that recollection is context dependent whereas familiarity is context-independent. Another distinction is that familiarity is generally an unconscious or automatic process whereas recollection is a conscious effort.

Remembering involves a conscious effort of retrieving information. When you take a history exam you are making a great effort to remember people’s names, places, and dates related to the context of a certain time period or important historical event. When you burn your hand on a stove, for example, when you are older and come across a hot burner you instantly recollect that hot stoves burn and cause pain. This recollection is intuitive—you know that you will get burned again so you avoid contact with the hot burner.

A recent study conducted by Sam Harris and colleagues at UCLA and the University of Southern California found that comparing religious with nonreligious statements reveals that religious thinking is more associated with brain regions that govern emotion, self-representation, and cognitive conflict whereas thinking about ordinary facts, in both believers and nonbelievers, is more reliant upon memory retrieval networks. Activity in the brain's anterior cingulate cortex, an area associated with cognitive conflict and uncertainty, suggested that both believers and nonbelievers experienced greater uncertainty when evaluating religious statements. The study goes on to explain the case for belief being content-independent.[i]

So when believers declare that they know God exists, they aren’t claiming to actually have met God, they are stating that given their experience they believe God is real. This may be described as “experiential knowledge” but it is not “epistemic knowledge” in the sense that it isn’t about the nature of the claim so much as it is about the nature of the experience which compels a religious person to make the claim in the first place. Recollection, on the other hand, has an epistemological basis. It is a matter of the nature of knowing about something, therefore retrieving the information which will qualify the statement as factually true. Therefore when making a literal claim about the existence of God, for example, it is not factually true to say “God exists” because there is no information about God we can retrieve, but it is factually true to say “No gods exist” for the same reason. Atheism, and more generally nonbelief, is therefore epistemically valid positions to take, whereas religious belief is often unfeasible and not epistemically quantifiable and as a result cannot be determined true.

Conditioned to Believe
Belief being content-independent means that we are intuitively detecting elements of truth which relate to our everyday experiences and then finding the best inference, and thereby finding reasonable provocation to believe in any proposition which seams to make sense (given our experiences). Thus a religious person will be more inclined to feel the statement that “God exists” is a true statement because it coincides with their religious or spiritual experiences as a person of faith. Therefore it is perfectly reasonable for a Christian or a Muslim to espouse great affirmations in the existence of God or Allah and the underlying truths of their respective religions. The problem, however, is this: cognitive science reveals that reasonable beliefs are not always rational.

Take for example the following: I find it perfectly reasonable to believe that my wife is the most beautiful (attractive) woman on the planet. My life experience, the context of being married to her and enjoying her reciprocal love and company, all condition me to believe such a claim is truthful just as it is reasonable. But in actuality it is not a perfectly rational claim. Why not? Because of a couple very important factors not to go overlooked. First of all, I have not met all the women who live in the world and so could never be positively certain that I would not find another woman more attractive, and also I nurture a strong bias when it comes to thinking about my wife and other women. This bias is obviously unreasonable in determining whether or not my wife is, in point of fact, the most beautiful and attractive woman alive for these following reasons:

1)                         I love and respect my wife and don’t want to hurt her feelings (even if one day I should come to find another woman more attractive, no matter how doubtful a scenario it is). This means I will inevitably favor her over other (perhaps) equally beautiful women.
2)                         As the adage goes, beauty is in the eye of the beholder. In other words, because of my genetic make up, my past experiences of which have conditioned me to find certain features more attractive than others, and my proclivity toward finding almond shaped eyes, dark hair, and soft facial features more attractive my personal taste is for Asian women—who I find more attractive than Caucasian women. Yet this is strictly a matter of preference and personal taste. Other people find other types of features more or less attractive.
3)                         Based on my understanding of fidelity, a cultural component to monogamous relationships, I am culturally conditioned to desire only my wife (even as my biological desire for other women seeks to interfere with my cultural conditioning). Therefore, it serves me as a means of assuring that my wife will mutually return my emotional commitment to her as the only woman in my life who I will deem the most attractive. Failing to do this would be detrimental, and although it does nothing to prove to you that my wife is the most attractive woman in the world, it does everything to convince me of that fact. I believe it because I find it reasonable, even though it’s not entirely rational.

When religious believers say they believe in God, I don’t doubt them for a second, but much like the previous example with my wife, we must realize they are not making a rational judgment but rather an emotionally biased one. Therefore the claim “God exist, he is real, I know it in my heart,” is not an epistemically valid truth claim. It’s a profession of belief. It is an emotional consideration one is inured to favor over other possible truths since they have been culturally conditioned to find such a claim both meaningful and emotionally satisfying (to them).

Likewise, when it comes to the religious claim that God is the source of morality or the belief that you need religion to be morally good, these are not truth claims about God, ethical behavior, or the influence of religion but rather they are conditioned beliefs one finds reasonable because they relate to their personal (subjective) experience(s). In order for the claim to have an credence whatsoever the first claim, e.g. that God is real and a source of goodness, must be confirmed. But this brings with it the original objection that this is not a factual claim which can be epistemologically verified—it is not rational. Although it may be “reasonable” for the adherent of faith to believe in such, it still remains epistemically unverified, makes no real world predictions, and therefore is an invalid truth claim. In other words, the claim is false even as there is reason to believe (or rather, desire to believe) the claim is true. This is the problem with religious belief as I see it. Thus any claim that revealed religion or faith is true, or that morality comes from God, are not truth claims, but instead, are appeals to authority. Thus nonbelievers are well within their right to reject such claims and consider them false.

Jean-Pierre Changeux has made an interesting comment in relation to the claim to authority and the way our brains process information in his engaging book The Physiology of Truth: Neuroscience and Human Knowledge. Changeux suggests that

By removing the possibility of appeal to supernatural authority, it places the full burden of moral responsibility on our shoulders as human beings. The search for the neurobilogical bases of consciousness and rationality, far from impoverishing our conception of human integrity, offers an unprecedented opportunity to properly value the multiplicity of personal experience, the richness of cultural diversity, and the variety of our ideas about the world. More than this, by making it possible to regard moral norms as distinctive expressions of a general disposition to ethical behavior, it suggests new ways in which the rights of individuals may be harmonized with their obligations to the social community of which they are members. (Changeux 2002, p.28)

Morality, then, does have a naturalistic basis, and so the appeal to religion is unnecessary—except for the fact that the religious have been conditioned to think that way.

In conclusion, the epistemology of truth makes it abundantly clear that religious claims about the existence of God, morality, and the like are not factual truth claims but are emotionally conditioned beliefs. Thus when it comes to being vindicated in ones claim, whether in a religious debate or any other dialectic, we now can better detect what is true and what is (most probably) false. Now that neuroscience provides a working model of morality and explains how our brains function we can better distinguish between genuine truth claims and professions of belief. Consequently, this helps us to do away with erroneous religious and supernatural claims, such as “God exists” and “Morality comes from religion/God,” and gives us incentive to start looking toward science to better explain such phenomenon and hopefully aid us in discovering the real answers.

Epistemology 101: Part 1 On Ontology and the Failure of Reformed Epistemology


Epistemology: [mass noun] (Philosophy) the theory of knowledge, especially with regard to its methods, validity, and scope, and the distinction between justified belief and opinion.


Due to numerous Christians now claiming that neuroscience cannot reveal whether morals exist independently of the brain, and that any subject related to morality must be relegated to the religious domain, I am going to do a series of articles in which I lay out the basics of epistemology and show exactly why Christians who espouse this are not only wrong, but they aren't doing themselves any favors, since ultimately--even if a external or independent form of morality should exist--our understanding of it would still be limited by our finite senses and interpreted subjectively by our brains. 

Even so, Christians keep telling me objective morality is primarily an ontological concern, and secondarily an epistemological concern, i.e. what we can know about it. What they are in essence claiming is that morals exist independently of human psychology, thus only ontologically justifiable (yet how this accounts for ontological mistakes I can't presume to guess), and only then can they come to be understood through the practice of epistemology. 

Stripping it down to it's most common form, the theists claim is this: morals exist because God exists, therefore we can pinch these morals out of sacred texts, holy laws, divine dictates and what not, thus coming to a better understanding of what it means to be moral. As an atheist and a naturalist I take umbrage at such a wildly unfounded, unsupported, and seriously flawed claim such as this. Therefore, I will first show how ontology does us no good with respect to moral issues, and secondly, I will show that objective morals can be had even with the limitations of our brain and its subjective reasoning. If successful, these proofs will thereby lend positive support for naturalism and the atheistic worldview.

Ontology: A Few Objections
Still many theologians such as Alvin Plantinga, William Lane Craig, Alister McGrath, etc., believe that the magical powers of the Holy Spirit can counter act the brain's limitations (although how one would prove that I have no inkling of a clue), and somehow reveal insights into the mysterious workings of God's divine will, but the truth is until such a statement can be proved beyond a shadow of a doubt (verification only then making the claim credible) it is a weak claim which should not be relied upon for the single basis of objective morals and values.

For example, the famous theologian Alvin Plantinga developed something called Reformed epistemology. Basically, according to Reformed epistemology, belief in God can be rational and justified even without arguments or evidence for the existence of God. 

All this amounts to is the wet and sticky smack of sophist nonsense, because anybody who understands the implications of such a claim realizes that this voids the empirical worldview, by basically stating we can gain knowledge and understanding through other means than experience, which subsequently means the empiricist's account of experience, i.e. nihil in intellectu nisi prius in sensu (nothing in the intellect that was not previously in the senses) is also void. As a consequence this renders skepticism moot, and therefore asking the question to begin with would prove futile, and as such could never be the correct way of reaching any given truth or gaining any understanding of it. 

In this sense a skeptical worldview founded on radical empiricism  would seem to render Plantinga's Reformed epistemology self refuting. Epistemology, if anything, must be predicated on our experience of gaining knowledge--this is known as foundationalism. If you amputate experience from the process of how we accrue knowledge, apply knowledge, and/or actively seek knowledge then you've simply denied there is such a thing as knowledge to be gained at all. And since our epistemic instinct is that knowledge is real, and that we can come into possession of it through experience, then once again it stems to reason that Reformed epistemology is self refuting.

If you took the metaphysical point of view, however, you also have other problems, such as having to account for ontological errors, or answer for how you can know things which cannot possibly be verified through empirical means. This is why the theologian is so happy to invoke ontological arguments in his favor anytime he runs up against the burden of having to divvy up the proof to back up any of his claims. It's much easier just to say it is simply epistemologically valid to believe, yet that takes us right back into the self refuting digression of Reformed epistemology.


As such Reformed epistemology is clearly a fallacious concept, but at the same time a vacuous one as well. 


The Failure of Reformed Epistemology 
Alvin Plantinga's Reformed epistemology fails, not only for the reasons mentioned, but because he is basically claiming that you can have an objective moral reality (via the ontological premise) without appeal to any basis in reality whatsoever (basically minus foundationalism), and this is clearly unsatisfactory.
 
What Plantinga's hypothesis boils down to is a "warrant to believe" (in God) which he thoroughly develops in his three volume series beginning with Warrant: The Current Debate, Warrant and Proper Function, and Warranted Christian Belief. I guess it's worth reading if you're interested in epistemological matters in how they relate to sustaining theistic belief, but beyond that Plantinga doesn't offer much in the way of the general function of epistemology (epistemology proper). So why then would I single out Reformed epistemology if I put no weight behind it with regard to moral issues? Because many Christians do (whether they know that's what they're doing or not is a different matter), and what's more they often misuse it as a means to rule out any subjective basis for objective morality which naturalists and nonbelievers may appeal to. This often leads them to claim that atheists are godless heathens and without a moral compass, but this is a mistake for reasons which will soon become clear.

The problem here being that most theists, and Christians, frequently have the wrong understanding of how facts relate to ontological and epistemological concerns. As Sam Harris details in his controversial new book The Moral Landscape:


...many people seem to think that because moral facts related to our experience (and are, therefore, ontologically "subjective"), all talk of morality must be "subjective" in the epistemological sense (i.e., biased, merely personal, etc.). This is simply untrue.


Harris clears this up by offering an easy to follow analogy.


After all, there are countless phenomena that are subjectively real, which we can discuss objectively (i.e., honestly and rationally), but which remain impossible to describe with precision. Consider the complete set of "birthday wishes" corresponding to every conscious hope that people have entertained silently while blowing out candles on birthday cakes. Will we ever be able to retrieve these unspoken thoughts? Of course not. Many of us would be hard-pressed to recall even one of our own birthday wishes. Does this mean that these wishes never existed or that we can't make true or false statements about them? ....Clearly, we can make true or false claims about human (and animal) subjectivity, and we can often evaluate these claims without having access to the facts in question. 


Indeed, I myself continually run into Christians who say that I have no authority to speak about moral claims because my opinions are only ontologically subjective, and that with regard to ontological claims, only an independent ontological reality could provide to the proper epistemological basis for discussing moral claims (this is a form of holism). 

This, however, is clearly problematic since you can simply disprove a holism by showing one part which can function independently separate from the rest.  In moral terms, what this means is that *if God was a moral source, and thus morality had an ontological basis, that in order to be moral you would have to rely on this understanding of morality first in order to be moral. 

Contrary to what theists may believe, there are many walks of life hailing from all areas of the globe, with various customs and differing beliefs, including atheists, who exhibit moral behavior without appealing to the Christian understanding. This defeats the holistic premise that morality has an ontological basis with how it relates to God, since even atheists can be kind, loving, moral people, therefore we can refute the idea that morality depends on an ontological holism. 


Therefore there is no independent objective morality to be gained via ontological methods. Morality, then, must exist independently. The question then becomes, what sort of morality exists in a naturalistic and atheistic world? Is it merely subjective? Or can there be an objective morality as well?


Objective Reality is Only Ever Subjective
Thus objective morality can be defined without religious metaphysical claims and without any appeal to an ontological basis for support. But more importantly, if we give the theologians and religious believers the benefit of the doubt, if for example there was an external or independent objective moral reality, then the only way we could possibly come to gleam insights from it are through our experience, skeptical inquiry, empirical reasoning, and finally coming to an understanding via epistemological methods--all of it subjective. Meanwhile modern neuroscience seems to confirm this conclusion, showing the brain to works strictly in this capacity yet yields sufficient reason to believe in morality as a neurological phenomenon and so making any ontological premise untenable (not to mention unnecessary).


Ontology can be explained as a neurological construct created by the limitations of the brain. For more on this please refer to:

So if we take the metaphysical approach and then objective morality is ever only subjectively understood and hence merely relative. This may explain why so many different religions think about morality differently and what's more have strong dissenting views on how to practice this morality--which is directly reflected in their religious behavior.

Yet if we take the naturalistic approach we can use science and philosophy to help guide us to understanding the benefits of moral considerations by testing and applying those which enhance human happiness and flourishing. Any moral truth, after all, would need to involve these two things, otherwise it would not be applicable to us. 

Needless to say, many religious "moral" concepts conflict with human happiness and flourishing. For example suicide bombing does little to enhance either, while the Catholic practice of confessing of one's sins and saying a few hail Mary prayers may ease a guilty conscience it does nothing to prove the happiness or flourishing of the human race. In both cases each is a selfish act, which is deemed "morally" beneficial to the person of that faith, and therefore only applies to the local moral values as defined by that religious group, but in reality has nothing to do with the objective reality of morals or values.
 
Objective & Subjective Reality Minus the Metaphysical Conjecture
In order for and external or independent objective moral reality to exist as Christian theologians like to claim exists, they first have to prove a whole litany of metaphysical claims, which by their very tenuous nature require more than just an appeal to ontological reasoning, and therefore defeat the purpose of Reformed epistemology. So let's do away with the assumption, shall we? We now know that beliefs, whether about morals, values, or birthday wishes can be subjective and still contain objective truths--even as we may not fully understand the nature of these truths or be clear as how they came to be--the thing we can be clear about, however, is that these truths are not metaphysical in nature and have no ontological basis for support.


Next time:
In the next article I will show how epistemology in the form of modal logic helps us define basic truth claims.
