Humes scepticism and Ash'ari Response. Sufficient? Some themes stood out:
1. The equivocation between philosophical skepticism (which, in truth, has taken varied forms) and that of modern-day skepticism as disbelief. The first is not a doctrine of disbelief. It, instead, is a doctrine—sometimes acknowledgedly expressed in seemingly self-contradictory manners—that a certain form of certainty, what may be termed absolute inferential certainty, is not attainable. (This, to me, is only shorthand for saying that though absolute inferential certainty might be possible, no one has yet demonstrated any instantiation of it and, for justified reasons, in all likelihood never will.) However philosophical skepticism is worded, though, if the proof is in the pudding, so to speak, one will find few schools of philosophical skepticism that upheld a satisfaction with disbelief toward any addressed topic, much less one that upheld a ubiquitous disbelief in all topics. [Debate can result as to what was meant when some schools affirmed the ideal of “suspension of belief/judgement”—but this can easily be interpreted as upholding an open-mind toward topics guided by empirical evidence and reasoning.] Hume is very much included in this tradition of philosophical-skepticism-founded systems-of-belief concerning what is (rather than an upholding of disbelief as is connoted by modern-day semantics of skepticism).
2. Equivocations between various types of certainty. For example, we all hold intuitive certainties and we all know that these are vastly different from out inferential certainties. Inferential certainties themselves come in various types and strengths. Though, I grant that a satisfactory categorization of certainties has so far been lacking. Nevertheless, it is only what some hold as the holy grail of absolute-inferential-certainty that philosophical skepticism traditionally disavows—this holy grail being all too often implicitly upheld culturally as being the only type of true knowledge (this presumption of what “true knowledge” is being something that skeptics such as Socrates/Plato and Hume would in all likelihood disagree with, imo: again, confer with their body of work as concerns knowledge of what is). And it can be readily argued that common sense is a product not of inferential certainties but of communally held intuitive certainties … at least some intuitive certainties being comprised by what Hume termed instincts—Hume relied upon instinct to far greater extents than any of his contemporaries.
3. The erroneous assumption that philosophical skepticism has emerged as a reaction to the belief in god—this rather than due to intentions to be closer to that which is (maybe all too ironically for some) objectively true … at least as concerns epistemology. Socrates/Plato serves as one example of what can, at least by modern standards, be termed a theistic philosophical skeptic (albeit not an Abrahamic theist). And, as the second post points out, neither does Hume uphold a disbelief in divinity of itself—rather, he argues against certain interpretations common to his own times.
4. The erroneous association of skepticism to a disbelief in realism. Again, if the proof is in the pudding, Hume, for one example, in no way disavowed realism; and, for that matter, neither did Socrates/Plato, nor did the academic skeptics which followed (these being of the Platonic Academy).
5. As to the overtones of one Abrahamic religious tradition having an upper hand over the other two, it can be noteworthy that all three, at least in certain schools of each, will uphold that the true God is ineffable; i.e., that although the true God is, it (in due respect to those that are reverent, “He”) cannot be cognized by us as form (though “He”, too, is form). This is the hundredth name of Allah; this is the G-d or Judaism; and can at the very least be found in the Christian “apophatic theology” as means of comprehending God, more common to Eastern Christianity (God is, and is not [limited by] anything that one can ascribe to God’s being). In so being, all three religious traditions can then be interpreted to refer to the same ineffable given—though through different customs, traditions, practices … through different forms/ideas of cognition. All three traditions, in this light, are then on equal footing. (But yes, in saying this I also acknowledge the more dogmatic beliefs of what God is as form … which can likewise be found in all three traditions, though here they stand in contradiction.)
That stated, the likelihood approach to a conviction in God which has been outlined in the second post would not, in and of itself, be a sufficient means of attaining inferential certainty (even if not absolute) in the presence of God. All of the principles mentioned for the argument from likelihood can be questioned by some … and this because they’re not sufficiently justified.
But, yes, philosophical skepticism isn’t the easiest philosophical approach to work with.
