The Problem of the Criterion

In the process of reviewing Shawn Lazar's book, Scripturalism and the Senses, I came across the following statement:

Reformed Epistemology provides Neo-Scripturalism with a better definition of knowledge. As you may remember, Nash criticized Clark for having an idiosyncratic definition of knowledge, that it was too narrow, reducing most of what we know (or claim to know) to skepticism, such as beliefs that we are married we children. With the help of Reformed Epistemology, Neo-Scripturalism can better account for what is popularly taken as knowledge.

Whether a definition of "knowledge" Plantinga et al. have provided actually is "better" than what Clark proposed is something I will address elsewhere. My primary interest is Mr. Lazar's justification for his conclusion. He thinks the definition he outlines in his book "can better account for what is popularly taken as knowledge."

Why this interests me is that it reminds me of the "Problem of the Criterion." I first remember reading about the Problem of the Criterion in a paper by Richard Fumerton (link), my introduction to present day epistemological discussions. So this was one of the first issues that caught my attention and led to me considering Scripturalism in contemporary contexts. It has been a long time, but if I recall correctly, it was also from this paper that I was inspired to think about necessary and sufficient conditions for knowledge (link, link).

At any rate, there seems to be a hidden assumption implicit in the above quote. After all, why should one care "what is popularly taken as knowledge"? Are Mr. Lazar and Nash prepared to dismiss any views that are generally unpopular... like Reformed theology itself? I doubt it. It seems to me (and I think Mr. Lazar and Nash would agree) that the important questions in the field of epistemology have little to do with adjusting a definition of "knowledge" to fit what the majority think is true.

So what did Mr. Lazar really mean? If I have misunderstood Mr. Lazar, Nash, and others, they are free to correct me on what criticism of Clark's definition is really intended. But even if that is the case, the following considerations are worthy in their own right. Assuming I am correct, I believe that what may drive Mr. Lazar, Nash, and others away from Clark on this point is the hidden assumption of epistemic particularism. Epistemic particularism is one answer to the Problem of the Criterion:

...perhaps the best way to formulate the Problem of the Criterion in its most general form is with the following pair of questions (Cling (1994) and McCain and Rowley (2014)):

(1) Which propositions are true?

(2) How can we tell which propositions are true? 

...These are not questions about the nature of truth itself. Rather, these are epistemological questions concerning which propositions we should think are true and what the correct criteria are for determining whether a proposition should be accepted as true or false. It is possible that one could have answers to these questions without possessing any particular theory of truth, or even taking a stand at all as to the correct theory of truth. Additionally, it is possible to have a well-developed theory of the nature of truth without having an answer to either (1) or (2). So, the issue at the heart of the Problem of the Criterion is how to start our epistemological theorizing in the correct way, not how to discover a theory of the nature of truth.

...The problem yielded by the Problem of the Criterion arises because one might plausibly think that we cannot answer (1) until we have an answer to (2), but we cannot answer (2) until we have an answer to (1). So, at least initially, consideration of the Problem of the Criterion makes it seem that we cannot get our theorizing started at all. This seems to land us in a pretty extreme form of skepticism—we cannot even begin the project of trying to determine which propositions to accept as true... 

According to Chisholm, there are only three responses to the Problem of the Criterion: particularism, methodism, and skepticism. The particularist assumes an answer to (1) and then uses that to answer (2), whereas the methodist assumes an answer to (2) and then uses that to answer (1). The skeptic claims that you cannot answer (1) without first having an answer to (2) and you cannot answer (2) without first having an answer to (1), and so you cannot answer either. Chisholm claims that, unfortunately, regardless of which of these responses to the Problem of the Criterion we adopt we are forced to beg the question... (link)

I will deal with Chisholm's claim that all responses are question-begging a little later. For now, the point is that Mr. Lazar's, Nash's, and others' aversion to (or, in some cases, derision of) Clark's definition of "knowledge" seems to stem, at least in part, from Clark being unable to say that he "knew" his wife. The various arguments seems to run as follows: people intuitively find [and should very much like to think] that they "know" their wives, and so any definition of knowledge which rules such out is "too narrow" (i.e. worse than one which does not rule such out). Others likewise have such intuitions, which is why such knowledge-claims about the subject are popular. All of this sounds like epistemic particularism:

Particularism: Assume an answer to (1) (accept some set of propositions as true) that does not depend on an answer to (2) and use the answer to (1) to answer (2).

That is, one begins with what counts as "knowledge" (1) and then attempts to formulate an understanding of how he "knows" such (2). That is, since we "know" our wives (1), let's talk about how we can tell that we "know" them (2). Here is the main problem epistemic particularists must face:

...The problem with particularism is that the particularist’s starting point is an unfounded assumption. Particularism starts with a set of particular propositions and works from there. If the particularist goes beyond that set of particular propositions to provide reasons for accepting them, she abandons that particularist response and either picks a new set of particular propositions to assume (a new particularist response) or picks something other than simply a new set of only particular propositions to assume and ceases to be a particularist.

In other words, if one begins his theorizing by saying "I know my wife," one can't very well provide reasons to justify the claim. For any such attempt to justify this claim would be theory-laden, grounded in the very particularist claim about being able to know his wife in the first place. 

Thus, I could say "I know you don't have a wife" and construct a theory of "knowledge" on the basis of that [and perhaps other] particularist claim[s]. I would then be a particularist whose propositional content is in direct conflict particularists like Mr. Lazar and Nash. Since neither claim would seem to be in a better position than the other - precisely because both conflicting claims were themselves the starting points for any further theorizing about how one can tell what "knowledge" even is - it doesn't appear possible for a third party adjudicate between the conflicting claims without first appealing to a methodology.

Before deciding whether or not this argument against particularism is a strong one, let us turn to methodism, for Chisholm also describes the methodist answer to the Problem of the Criterion as question-begging:

Methodism: Assume an answer to (2) (accept some criterion to be a correct criterion of truth – one that successfully discriminates true propositions from false ones) that does not depend on an answer to (1) and use the answer to (2) to answer (1).

Since methodism begins by assuming that some criterion is a correct criterion of truth without providing any epistemic reason to prefer this response to the alternatives, it begs the question against particularism and skepticism.

The methodist would propose a criterion by which one could determine whether or not one is married. This avoids the above dilemma that conflicting particularists may face. However, does it not run into an analogous problem? What if one proposes a different criterion for knowing truth than another? How can such a conflict be any more resolvable than epistemic particularism? 

Again, before attempting to answer any of these questions, I think it is worth noting that Clark affirmed methodism:

Physicists used to say that light consisted of ether waves. Today it is generally agreed that the methods used were defective, and that light is something else (they don’t quite know what). Hence even if botany or theology is written first, it cannot be accepted by a scholar until the crucial question is answered: How do you know? In a systematic treatment, the methodology ought to come first. Instead of asking, What is a cactus? or What is light? someone asks, What is God? How can one go about answering that question? Do we consult the Koran or the Vedas? Do we study the stars? Do we send a questionnaire to a thousand college professors? A method must be chosen (or used unwittingly) before any answer is forthcoming. Henry’s method is to consult the Bible and from it deduce that God is a spirit, infinite, eternal, unchangeable. We cannot start with God; we must start with the Bible. Why not say so first and then proceed to the theology the Bible teaches. (God’s Hammer, 1995, pg. 178)

But to return to the main subject: What one learns first from the Bible and what he learns second and third varies from man to man. One person begins with Genesis; another begins with Matthew. Similarly, a man may learn several propositions about God without reflecting on the method by which he learned them. Musicians and painters usually produce good works of art before they understand the theory. Hence in temporal psychology a knowledge of God precedes a knowledge of method. But to explain this process an apologist ought to start with the methodology. For while the unreflective reader may be unaware of the methodology – he may not realize how he does what he does – he nonetheless uses the method. And for Clark and Henry the method is Scriptural. (God’s Hammer, 1995, pg. 179, 184-186)

[As an aside, Clark's statement that "a knowledge of God precedes a knowledge of method" is interesting. It seems that in this context, Clark is affirming doxastic justification as parasitic on propositional justification (link). As will be seen in a below quote, Clark is concerned 1) that a learner is made aware, by the apologist, that he has a method as well as 2) that the learner is using the "right method." 

I am tempted to relate this to my recent reflections on Clark's view of "natural knowledge" (link) in that while Clark argued that heathens could possess such - at least, on a definition of "knowledge" as "true belief" - the apologist's job is to ensure that one begins to reflect on what "knowledge of God" they have (a la Acts 17). When this is accomplished and the learner is brought to acceptance of the right method of Scripture as his rule of faith and known, by grace through the work of the Holy Spirit, one's "knowledge" can be elevated to an epistemic status that allows for full assurance. Perhaps that oversteps a historical characterization of Clark's own thought, but if so, it would be how I personally would develop Clark's epistemology.]

I imagine Clark would identify "intuition" as the implicit method of epistemic particularists. Regardless, this would also help to account for why some's concerns for being able to know their wives were of no concern to Clark:

Granted, it is unlikely that anyone should go to such extremes to substitute another woman for the wife of an unimportant theologian or philosopher. But how do you know? So long as substitution is possible, certainty is impossible. (Clark and His Critics, 2009, pg. 75)

What, then, can we say to all the worries of question-begging? My own view of the entire situation is best answered after mentioning the "last" option to the Problem of the Criterion:

Skepticism: Assume that (i) there is no independent answer to (1) or (2), and (ii) if (1) and (2) cannot be answered independently, they cannot be answered at all.

Now, recall earlier Chisholm's claim that "unfortunately, regardless of which of these responses to the Problem of the Criterion we adopt we are forced to beg the question." The careful reader will notice that out of the three options stated thus far - particularism, methodism, and skepticism - one more option has been left out. Reread the above skeptical response without (ii). 

Perhaps there is no independent answer to (1) or (2). Even so, such does not need to be viewed as problematic, because to answer (1) and (2) simultaneously is indeed, contra skepticism (which, I think, is itself a self-referentially incoherent position to take on the question), an answer.

Thus, do we construct a definition of knowledge to capture experiences that intuitively seem to belong together (particularism)? Or do we begin with a definition by which we categorize particular experiences (methodism)? This is a false dilemma. Why? Because a methodological criterion for knowledge can itself be [particularly] known. Is it not question-begging to assume otherwise?

I can imagine a few objections to this, most of which spiral out of discussing the Problem of the Criterion itself. The most relevant criticism might be if one argued that what I am proposing is little different than those who identify solely as epistemic particularists or methodists. 

In response, obvious differences between must be highlighted. Stating that "I am married" is an instance of "knowledge," not a method for arriving at other other knowledge-claims. Thus, there is no counter-apologetic available to solely epistemic particularists who encounter other solely epistemic particularists who conflictingly claim "you are not married" as an instance of "knowledge." In contrast, Scripturalists who synthesize particularism and methodism do have counter-apologetics available against copy-cat opponents, as will be demonstrated below. Similarly, starting with a method for knowing things is not to say that one knows the method itself is true. Thus, there is as big a difference between solely epistemic methodists and those who synthesize particularism and methodism as there is between epistemic positism and foundationalism. These are important distinctions that should not be overlooked.

Another, more tangential criticism might be that even with the above distinctions in mind, someone else might attempt to likewise synthesize particularism and methodism by providing a different "methodological criterion for knowledge they claim that can itself be [particularly] known by the method itself." Does affirmation of one not beg the question against the other?

A few things ought to be stated in response. Firstly, the idea of question-begging is itself a concept that depends on a particular theory of knowledge. Solomon wrote, "of many books there is no end, and much study is a weariness of the flesh." (Ecc. 12:12). He might as well have written, "of many questions there is no end, and much answering is a weariness of the flesh." A fool can ask more questions than a wise man can answer. But can the fool himself answer what right he has to ask questions? Let any skeptics who ask questions designed to undermine the possibility of knowledge practice their inconsistency in silence.

To add to this point, if one interprets the Problem of the Criterion as an attack on foundationalism, he must be prepared to offer a non-skeptical alternative. By definition, infinitists would never be able to offer a complete answer to the Problem of the Criterion. And traditional, circular coherentists (for other versions of coherentism are foundationalism in disguise) no less beg the question than foundationalists and also have the problem of explaining how, if a belief cannot be self-justifying (as foundationalists can hold), reasoning in a circle "back" to a belief with which one "started" in a given conversation or thought-process adds or contributes to the justification of that belief.

Aside from these rebuttals, though, a more direct response to the question of how to adjudicate between two people who take particular, contradictory methods of knowledge as foundational for knowledge turns on the difference between epistemology and apologetics (and causation, for one cannot be argued into knowing truth by brute logic).

Let's say I claim that the criterion for knowledge is divine revelation - the extant extent of which is codified in or deducible from the Bible - a criterion itself knowable as such. I do, and Clark likewise made these claims:

But if there is a revelation, there can be no criterion for it. God cannot swear by a greater; therefore he has sworn by himself. One cannot ask one’s own experience to judge God and determine whether God tells the truth or not. Consider Abraham. How could Abraham be sure that God commanded him to sacrifice Isaac? Maybe this suggestion was of the devil; maybe it was a queer auto-suggestion. There is no higher answer to this question than God himself. The final criterion is merely God’s statement. It cannot be tested by any superior truth. (Today's Evangelism: Counterfeit or Genuine, 1990, pg. 113)

How then may we know that the Bible is true? The Confession answers, “Our full persuasion and assurance of the infallible truth and divine authority [of the Scripture] is from the inward work of the Holy Spirit.”

Faith is a gift or work of God. It is God who causes us to believe: “Blessed is the man whom thou choosest and causest to approach unto thee” (Psa. 65:4).

Logically the infallibility of the Bible is not a theorem to be deduced from some prior axiom. The infallibility of the Bible is the axiom from which several doctrines are themselves deduced as theorems. Every religion and every philosophy must be based on some first principle. And since a first principle is first, it cannot be “proved” or “demonstrated” on the basis of anything prior. As the catechism question, quoted above, says, “The Word of God is the only rule to direct us how we may glorify Him.” (What Do Presbyterians Believe? 1985, pg. 18)

Suppose another claims the same thing about the Quran. What to do? Well, one difference between this scenario - in which particularism and methodism have been synthesized - and the others mentioned above is that my foundation may also prescribe apologetic methods for refuting others, including showing that their own foundation is internally inconsistent. Indeed, this is again what Clark himself suggests: 

...if apologetics has the task of discussing secular systems, is not the apagogic method the best – the method of reductio ad absurdum? 

...apologetics must be derived from revelation. At the same time what seemed to be a lack of consistency or resoluteness led to certain proposals for improving and extending his apologetic method. The proposals submitted stressed apagogic apologetics, the unity of truth and axiomatization as the most consistent denial of a common platform with unbelief. 

...the Gospel has a point of contact, and apagogic argumentation can be extended. Not only may the apologete show the self-contradiction inherent in secular axioms, as we said above; he may now stress the inconsistency of accepting both a secular axiom and a divine truth; and he may draw out the inferences of the divine truth and show its consistency with the additional truths of revelation. (Karl Barth's Theological Method, 1997, pgs. 96, 113, 118)

In fact, Clark does an excellent job of extending meta-epistemic considerations along these lines to a defense of a unified, methodological foundationalism: 

This is one reason why methodology must be carefully considered. Is it the right method to begin with sensory experience, or with a mystic trance, and conclude with the type of God that later appears? In particular, will anything at all appear later concerning sin, atonement, resurrection, and so on? The Christian needs a method that arrives at all this. He needs a single method. Two methods produce a bifurcation that cannot be unified. Theology then would be schizophrenic. A theory of knowledge must cover all knowledge. If it does not, and if a person uses two methods he cannot answer the question, Where should the one be used, and where the other? He cannot use theory number one to define the place of theory number two, nor conversely, and hence he has no ground for choosing one rather than the other at any point. This means that he really has no theory of knowledge at all...

The method used in this book and the theology that necessarily results are Biblical. The principle is to take the Bible as a revelation from God. (link)

That being said, apologetics does have limitations. As Clark notes, "One who believes in the unity of truth may still believe that the false system entails contradictions; but to prove this is the work of omniscience" (Historiography: Secular and Religious, 1971, pg. 370). We are not omniscient. Has the Problem of the Criterion, then, remained a problem after all?

No, for fortunately, God is omniscient, God has revealed Himself to us, and His revelation is self-authenticating. While we cannot necessarily show contradictions that stem from others' foundations, then, that apologetic limitation does not prevent us from knowing they exist. Additionally, even in such situations, we can, nevertheless argue against other foundations. As Ron DiGiacomo notes:

The transcendental argument for the existence of God is an argument that has as its conclusion God exists.

Prove A: The Christian God exists.
Step 1 ~A: (Assume the opposite of what we are trying to prove): The Christian God does not exist.
Step 2 (~A--> B): If God does not exist, then there is no intelligible experience since God is the precondition of intelligibility
Step 3 (~B): There is intelligible experience (Contradiction)
Step 4 (~ ~A): It is not the case that God does not exist (Modus Tollens on 2 and 3)
Step 5 (A): --> God does exist (Law of negation.)
Q.E.D.

...So what about step 2 of the argument? We can defend the premise of step 2 deductively by appealing to the absolute authority of Scripture. Of course the unbeliever rejects that authority; nonetheless that the unbeliever is dysfunctional does not mean that an appeal to Scripture is fallacious! After all, if a skeptic rejects logic should we then argue apart from logic? Since when does the dullness of an opponent dictate which tools of argumentation may be used? Of course, given the unbeliever’s suppression of the truth the Christian does well to defend step 2 inductively by performing internal critiques of opposing worldviews, which of course can only corroborate the veracity of step 2. It would be fallacious, however, to conclude because of such condescension toward the unbeliever that the conclusion of TAG (God exists) and the justification for its step 2 (God is the precondition of intelligibility) rest upon inductive inference. By the use of induction the Christian is merely acknowledging that the unbeliever refuses to bend the knee to the self-attesting Word from which step 2 can be deduced by sound argumentation. Since unbelievers will not accept the truth claims of the Bible and, therefore, a deductive defense of step 2 the only thing the Christian can do is refute the hypothetical competitors, but that hardly implies that step 2 cannot be proved by deduction. (link)

Yes, a Muslim or others might try to copy this transcendental line of reasoning - and that is why reductio ad absurdem argumentation Clark recommends is an excellent apologetic tool that can, in certain contexts, be more persuasive than transcendental reasoning - but one who is worried about what hypothetical scenarios in which we can't perform a certain apologetic says about our ability to know the Bible is God's word rather than the Quran (or whatnot) ought to keep in mind that apologetics is subordinate to epistemology in the first place (link). What we know dictates how we argue and defend what we know, not vice versa. Those who find these apologetic defenses to be "question-begging" ought to re-examine whether they have rightly understood and distinguished the structure of epistemic justification from apologetic methods of defending of one's position (as well as the relationship between the two).
