A few days ago, a friend asked me for my thoughts on this video.
At the outset, the author, David Pallmann, asks,
Just what is presuppositional apologetics? It is a
school of apologetics which tries to show that Christianity is true via a
transcendental argument (minute 1).
Now, this is quite a narrow view of presuppositionalism, especially in light of my own criticisms (as a presuppositionalist) of other presuppositionalists who thought transcendental argumentation could conceivably enable one to reason to God (link). His classification of versions of presuppositionalism which might differ from that of Greg Bahnsen as "deviant" (minute 8) is rather restrictive. If nothing else, I hope this post illustrates that one ought to discriminate the varieties of presuppositionalist perspectives.
Mine bears an affinity with that of Gordon Clark and does not attempt to "show"
(prove?) that Christianity is true via argumentation. Any arguments Clark might
have made function as a defense of Christianity; but the arguments are not meant to
function as "proofs," as if God's word (Clark's foundation or axiom) could have somehow been
the conclusion to a (circular?) argument.
Many flawed criticisms of Clark by
fellow believers rest on a conflation between apologetics and epistemology. See
my distinction between the two here. In short, apologetics or arguments presuppose
epistemology or knowledge [of the most basic premise]. The two must be kept
distinct. Apologetics is subordinate to epistemology.
Another mistake is to
think Clark was a traditional coherentist. Even people who
claim to follow Clark's view sometimes make this mistake. He was a
foundationalist. See point 5 here. A reason people make this mistake is because Clark accepted a coherence theory
of truth; while I disagree with Clark on this, the point is that a coherence
theory of truth (i.e. a definition of truth) is different than coherentism in
epistemology (i.e. how we come to know the truth). See here.
At minute mark 5, David says:
In this video, I want to explore a
response that has been periodically hinted at in the literature but is never,
to my knowledge, been fully developed. I intend to defend the thesis that human
reasoning is autonomous.
Given that his final quote in the video is from a chapter on autonomous human reason in a book written as a challenge to presuppositionalism (free on Kindle Unlimited here, by the way), I found this quote confusing. Does he think that his video or channel fully develops a thesis Joe Depoe does not?
Regarding the idea of autonomous human reason, in 1943, Clark anticipated the idea that this might be a problem for presuppositionalists in an article he wrote for The Presbyterian
Guardian (link). Clark says:
A rational being, the liberals argue, cannot
abdicate the throne of his autonomy. He cannot avoid the necessity of making
the final decision, and even if he decides to abdicate, it is he who decides.
Further, if he should abdicate, the question would always remain whether or not
he should reascend the throne - and again it would be he who would make the
decision.
The liberal continues: Reason cannot abdicate because it must choose
from among different alleged revelations. And to try to persuade a person of
the truth of a revelation implies that there is a common ground of persuasion.
That common ground is reason. Anyone who argues or persuades at all recognizes
reason as the final court.
Is there any reply that an orthodox Christian can
make without denying the principle of authority?
The first observation is that
the fact that a decision is our own does not imply that we are the final
authority. If a person wishes to measure a distance, there are essentially only
two ways of doing it. He may look at the distance and guess its length. This is
not a very accurate method, nor does it make the guesser the final court of
appeal; but it illustrates the attempt to make one's unaided reason the final
court. The second method is to use an accurate measuring device such as a
yardstick. In using this method, it is we, of course, who make the decision,
but we appeal to the yardstick. And the second method has the advantage of
being much more accurate. In such a situation, most people do not object to
being bound by an external authority.
Since all analogies have their limits, a
second observation must question the matter of abdication. To abdicate a
throne, it is absolutely essential first to be on the throne. A person who has
never been king cannot possibly abdicate. The liberals simply assume that man
is on the throne, but that is the very point at issue. If God is on the throne,
and if man is not autonomous, then the liberal argument is completely
irrelevant.
A third observation is all that the present limits allow. The
liberal has argued that we must choose the yardstick, one revelation among
other alleged revelations, and that no doubt we seek to persuade others of the
truth of the revelation we have chosen. But to persuade is to appeal to the
common ground of reason.
This very plausible argument is obtained only by
misunderstanding the implications of supernaturalism. To convict
supernaturalism of inconsistency, it is necessary to represent it accurately.
The plausibility of the objection to orthodox Christianity results from
combining a supernatural view of revelation with a purely naturalistic view of
persuasion. And the result is easily shown to be inconsistent. But if
persuasion and revelation both are understood supernaturally, no inconsistency
can be found. For, be it observed, there is no such thing as a common ground
between the Christian and a nonchristian system. From a, world naturalistically
conceived, one cannot argue to the God of the Christians. From a world-view
that denies all revelation, one cannot produce a Biblical revelation.
Persuasion therefore is not an appeal to a common ground or to a nonchristian
reason. Persuasion must be regarded as a supernatural work of the Holy Spirit.
The true Christian presents the Christian faith to unbelievers, he explains it
and shows it in its fullness. Then the Christian prays that the Holy Spirit
regenerate, his auditor, renew his mind, and enable him to see the truth of
what has been said. This is not an appeal to experience, or to reason, or to a
common ground; it is an appeal to the sovereign God of the universe.
Around minute 10, David says:
By assumptions and presuppositions, I
mean beliefs that are taken to be true apart from independent non-circular
justification. In other words, I reject the idea that there are any beliefs
that must be accepted without a justifying reason.
I found this confusing too, since David elsewhere claims to be a foundationalist. The above quote appears to be a
form of infinitism (link), not foundationalism. Unless
I am misunderstanding him, his statement is not consistent with the rest of his
video.
At minute 12:20, David cites Timothy and Lydia McGrew:
...to claim that there can be genuine
epistemic principles that although rationally dubitable cannot be defended
against someone who is skeptical about them is to allow an indefensible
proposition to have epistemic weight.
I had to read my own copy of that book for some context. The context is this: "Regardless of whether... a proposition is true, if it really is indefensible, it cannot be used as a premise to justify belief in anything else. If it is indefensible, it is epistemically irrelevant" (Internalism and Epistemology, pg. 80).
The question seems
to be whether indefensible propositions can have epistemic weight (positive
epistemic status). David blows by this question very quickly - too
quickly (at this point) to allow for the nuance necessary to address the
question.
For instance, let's start with this: do axioms/foundations have
positive epistemic weight? Well, a foundationalist had better say that in
certain cases (i.e. God's word), "Yes, we can know axioms without having to defend them." There is positive epistemic weight regardless of whether
we attempt to defend them. If God's word is our axiom and we can't know our
axiom, then we are in trouble (this position is known as positism; link).
Now, does the above mean that it is impossible to defend axioms/foundations? In
one sense, yes; in another no. The epistemic justification of an
axiom/foundation is not determined by a prior reason, premise, etc. For a
foundationalist - as was alluded to above - the positive epistemic status must
be intrinsic to the truth of the axiom/foundation itself. I interact with
contemporary epistemologists on this very point here and here.
On the other hand, it is possible to "apologetically" defend one's
axiom/foundation. What does this mean? It means that in everyday conversations
with others, one can point out that his axiom/foundation coheres with that which is
derivable from it, that it answers important questions, etc. It is in this
sense that we can understand Clark's affirmation that: "by the systems
they produce, axioms must be judged."
A self-defeating axiom cannot be
defended (or known), whereas a self-consistent axiom can be defended insofar as
the claims of its adherent can be harmonious, although we should not say we
know said axiom by means of this or any other such defense.
In other words, I
agree with his denial around minute 13 of any attempt to circularly justify a
knowledge-claim. I (and Clark) reject traditional coherentism, since it would
be impossible to discriminate between circles without a foundational principle
(like John Frame's foundational principle about the different between
"narrow" and "broad" circles at minute 14; how could Frame
say one is better than the other without assuming axiomatically that there is a
difference in desirability?).
As an aside, it's a bit funny that if Van
Tilians defend traditional coherentism, then Clark's presuppositionalism is
somehow "deviant." One would think that the
very name of "presupposition"alism would more closely associate with
foundationalism, not coherentism.
Anyways, the point is that apologetic
defenses of axioms/foundations are practical and persuasive, not epistemic. I
put it this way in a post I have elsewhere said (link) I am planning to write in response to an article by Dan Kemp (link), whom David cites at minute 14:40:
When a
mom calls a child to dinner, she doesn’t need to identify who she is for the
child to "know" who is calling. If she did identify herself, such
self-attestation ("Ryan Hedrich, your mom is calling you!") wouldn’t
be "needed"... but it also wouldn’t be unreasonable. Self-attestation
might serve as a reminder to the child to take her words seriously. Aside from
questions of knowledge, such reminders might have a psychological or pragmatic
purpose (e.g. behavior reinforcement, mindfulness).
Apologetics or
defenses of our axioms can be useful in terms of being means by which the Spirit
convicts the hearts of others without thereby becoming premises or reasons by
which we somehow circularly know the axioms/foundations. Indeed, our methods
for apologetic defenses ought themselves to be derivable from our
axiom/foundation (e.g. 1 Peter 3, Acts 17, etc.).
One final point. A phrase
that David cites which caught my eye is "rationally dubitable." If David is
talking about principles that are open to rational doubt and whether these can
be defended in the face of a skeptic, he seems to suggest that if the answer is
no, there is a problem. But if I am understanding him correctly, I don't see
the problem? If something is "open to doubt" (dubitable), of course
it is possible a skeptic is going to doubt it. In fact, some skeptics will even
claim to doubt even those things which are indubitable, such as the revelation
or promises of God. Just because we can't prove to the skeptic that God's word
is God's word (or would David claim to be able to do this?) does
not mean there is a problem - nor does it mean that our axiom/foundation is
"rationally dubitable" after all. On this point, the problem with the
skeptic is ethical. He refuses to submit to the self-justifying truth of God's
word.
Maybe I am misunderstanding what David means by a "defense" - or maybe I am misunderstanding something else But
this is why it is important to provide some nuance to statements and quotes
of other authors. Instead, David skips quickly to the claim that he sees no other
way forward than to vindicate deduction and induction. That is much too fast a
conclusion. If it isn't a non sequitur, then at the very least, I couldn't
follow his reasoning.
At around 18:30, David distinguishes between "self-justifying" beliefs and "immediately justified" beliefs. He thinks the former implies justificatory circularity (traditional coherentism) and the latter implies foundationalism. I disagree with his definitions, and so do contemporary
epistemologists - see here, where Jeremy Fantl refers to "self-justifying" reasons or beliefs in the context of foundationalism. But to
be clear, I also reject justificatory circularity.
I've read Fumerton's work. I
actually quite like him. I gave a former student his introductory book on epistemology. At the same time, I don't agree with
everything Fumerton says (link). And I suspect that the idea of "direct acquaintance" (which David gets from Fumerton) might be another area of disagreement. He says:
Direct acquaintance with correspondence between truth-bearer and
truth-maker ensures that the belief is justified and infallibly so... Direct
acquaintance is not itself a belief but it relates a subject to a fact in such
a way that the subject is aware of the correspondence between his thought and
the fact that makes it true.
Notice what is being argued: justification
for beliefs depends on "acquaintance." But "acquaintance"
is not itself a belief. Well, if "acquaintance" is not a belief, can
"acquaintance" be a truth-bearer? If it can't, then how is it that
"acquaintance" can "ensure" the justification of beliefs?
Can that which does not bear a truth-value function as a justification for that
which does?
In other words, what does it even mean to say that direct
acquaintance can "ensure" justification? That sounds suspiciously
like saying that acquaintance is itself a logically distinct and preceding
justificatory condition for one's belief(s) - a reason. But this would
undermine the David's claim to be a foundationalist.
Relatedly, a topic in contemporary epistemology is how something without that is neither true nor false - say, a sensory experience qua experience - could function as a justification for the truth or falsity of a proposition[al belief]. This seems to be a directly
relevant question, for David goes on to say: "...one can be
immediately justified through direct perceptual awareness..."
Notice the
word "perceptual" (and see his headache example at minute 21 and his
direct reference to sensation at 21:30). Recall every Clarkian argument
against empirical knowledge (link). He even admits that one's sensations may not
correspond to external states of affairs (but attempts to suggest that our
beliefs regarding our private experiences are not open to question - this move doesn't work insofar as David later admits to holding to fallibilism, contrary to his above statement that direct acquaintance can ensure "infallible" justification, on which see below).
In short, his reply to possible objections at minute 22 is dismissive
and avoidant. He responds to an easy objection while failing to address more difficult ones (how is "direct acquaintance" able to function as
justification). This is a meta-epistemic concern, but meta-epistemology has
direct relevance to normative epistemology. Analogously, infinitism is a
meta-epistemic position on the structure of epistemic justification. If
infinitism is inherently problematic, an infinitist does not actually know
anything by the structure he claims is correct. If "direct acquaintance" is
inherently problematic, a direct acquantaincist does not actually know anything
by "direct acquaintance" (so-called).
This gets a
little deep, but here is another question David fails to entertain: while I agree
that there is a correspondence between truths and other realities - I reject
the idea that everything is metaphysically reducible to [sets of] propositions
- does that mean non-propositional realities (like my body) are truth-makers
(like propositions about my body)?
As a Reformed Christian, I rather think that
God is the truth-maker of all propositions. In particular, it is He who
determined the truth-values of contingent propositions in accordance with His
eternal decree. As such, it's possible that the truths God has eternally
decreed may, in some way, actually be means by which non-propositions (like my
body, which is not eternal) are made. For a probably clearer idea of what I'm
getting at, read this article by Clark in which he writes: "when
compared with verses in the Pentateuch the words strongly suggest that the
visible world came from a suprasensible, ideal world."
Moving ahead to minute 26: "Knowledge does not require certainty."
Three questions:
1) Is David certain of this? If not, wouldn't such an
admission be problematic in the possible case that certainty actually is
required for one's beliefs to count as knowledge (a possibility which I don't
understand how he could rule out non-arbitrarily)?
2) I thought that David earlier said, "Direct acquaintance with correspondence between
truth-bearer and truth-maker ensures that the belief is justified and infallibly
so..." What happened? When is and is not infallibility applicable to one's
beliefs?
3) If knowledge does not require certainty, then what does it mean to say that any beliefs
are "justified"?
Around 30:30, David shows the three potential responses to Aristotle's transcendental argument for the laws of logic. They are ones I've encountered and thought about before. In response, I will offer
three counters:
1. David basically says that "Aristotle might be
right that one must think in accordance with the laws of logic, but that this
doesn't establish anything is true." In response, two questions: 1) What
is the David's alethiology (theory of truth)? Perhaps one's alethiology
(which might entail consistency amongst true propositions) would entail that in
accordance with said theory, the laws of logic cannot be false. He somewhat
gets around to this at minute 37. 2) If David acknowledges that one
cannot speak without first assuming the laws of logic, then his own response admittedly presupposes the laws of logic. But in that case, is it
legitimate to use that which he might purport to reject? Is it legitimate to admit that a hilltop (truth) can only be reached by climbing a
ladder (the laws of logic) and then from said hilltop deny that he ever used a ladder? Ironically, in another video David makes against presuppositionalists, he cites a "magic 8-ball" illustration that it seems he himself falls prey to here.
2. David's response to Aristotle certainly
isn't a persuasive response. But that's how I interpret a correctly oriented
defense of the laws of logic in the first place: again, a defense or apologetic needn't be interpreted as a circular justification.
3. David's reference to
dialetheism returns us to the question of alethiology. This is probably the
strongest counter he raises (then again, he addresses his own concerns by providing a very good quote at 38:55 which undercuts dialetheim). I needn't say much more, since David denies dialetheism himself (44:45ff.).
Nevertheless, I will offer a few more thoughts. In
particular, are there some cases in which the law of noncontradiction do not
hold? Typically, a dialetheist will not be a trivialist; he will not
suggest that every pair of contradictories can be or are true (which is subject
to the principle of explosion).
Underlying this theory, then, seems the
assumption of alethic particularism: rather than start with a broad, theory of
truth (e.g. consistency among propositions which may correspond to kinds of
realities), we might start with what we consider are intuitive and particular
examples of truths - some of which might consist of contradictories which can
both be "true" - and attempt to form a resultant theory of truth
(such as dialetheism) with these examples in mind.
While I would like to flesh
an argument against dialetheism further than I am able at present, given the above,
one possible line of argument against it and its implicit alethic particularism
could perhaps be made along the same lines as I have made against epistemic
particularism (in isolation from epistemic methodism) here.
This is probably a more important point than I can emphasize here, for
repeatedly in the video, David often uses paradigm cases to defend his position. For example, at minute 36:10, he uses an particular example that he assumes his audience will
agree is justified to defend a broader methodological principle. That is, in
appealing to his audience's intuitions, he appears to be a
particularist, and if he is not, he does not sufficiently distance himself from
particularism; a quote around minute 52 might obliquely allude to it, but even
there, not enough context in the quote is provided to even understand its
purpose.
With the above in mind, can logic justify logic? No. Again, circularity is
not the structure of epistemic justification. In other words, we do not know
anything by reasoning in a circle. As I've mentioned before, though, we can
still make arguments for propositions we know non-inferentially or
foundationally. These arguments do not justify said foundations but can
function to persuade others [especially that alternatives to our view are
non-viable].
The laws of logic in particular are embedded within the
Scripturalist's foundation as a subsidiary, ontological precondition for
knowledge, as I argue here and here. Thus, our knowing them is, in
conjunction with our knowledge of God's revelation, immediate or non-inferential.
I don't have much further to say about his discussion on analyticity, except to
note that he doesn't think he needs to explain how we have them "so long
as we do" (minute 26:30). Well, does he have concepts? If the answer is
potentially "no," that is a serious problem.
But as I said in an
earlier post, God's word is not rationally dubitable. The problem the skeptic
has is one of ethical rebellion (which affects his ability to reason soundly,
not his ability to reason validly per se a la Clark).
David's part of the video on
induction was extremely weak. He did not address the question of what number of
observable cases would suffice for epistemic justification. He does not address
what constitutes a "large sample." The concept of "large"
is finite and therefore relative. As one might approach infinitely many
observations, any concrete number of observations is infinitesimally small by
comparison... in which case, is not an inductivist's epistemic justification
(and "confidence" therein) virtually (as well as really)
non-existent? This is a much more difficult issue than David intimates.
In my opinion, the best one can expect on this topic is doxastic defendability.
A Scripturalist (and only a Scripturalist, insofar as any kind of "defenses" are
parasitic upon internalist and infallibilist "knowledge") might be able to defend his extra-Scriptural beliefs
to the extent that they conform to his alleged experiences (this would be
inductive), but he must also be open to revising such beliefs in the case of
alleged defeaters, e.g. experiences which do not conform to what he has experienced
previously. This theory only would apply to extra-Scriptural information, and
it would not qualify as strict epistemic justification (although we might also colloquially refer to any such beliefs as "known").
Another reason
the response to the problem of induction was weak was because David only
went so far as to address Hume's skepticism. Clark's concerns regarding
induction - as an anti-empiricist - deserved more attention than Hume's.
My friend mentioned that he thought David is an evidentialist. In his last part of the video, I can see why: he says as much. In particular, at 1:00:50, he cites an author who says, "the
epistemic justification of a belief is determined by the quality of the
believer's evidence for the belief." Again, I am confused how such a view
can be consistent with foundationalism. If foundations do not rely on evidence,
then one's justification for one's foundational beliefs cannot fall within the
realm of an evidentialist theory. David appears plainly inconsistent on
several points.
David concludes, "...the Christian [presuppositional] apologist tries to
gerrymander the rules of epistemology..."
I had a
good chuckle at this! Still, I enjoyed the video insofar as I'm glad to see professed Christians engaging in contemporary epistemological issues. I agreed with him regarding
foundationalism, the resolvability of paradoxes, and some other points. I
wouldn't want my above responses to be taken as suggesting his videos are
valueless, only that, as with anyone (Clark and myself included), one must
wisely apply discrimination where appropriate.
