It is also certain that when we assent to some piece of reasoning when our perception of it is lacking, then either we go wrong, or, if we do stumble on the truth, it is by accident, so that we cannot be sure that we are not in error.

Animal knowledge is metaphysically constituted by apt belief, by belief whose correctness manifests the believer's epistemic competence, a relevant disposition to get it right on the matter at hand when one tries to do so.

In my view there is a level of human knowledge that involves just getting it right aptly. This "animal" epistemic level is an inferior level in just the way of Diana's long shot in the dark while drunk. That shot is inferior in a certain respect if too poorly selected as a hunter's archery shot, even if not quite as poorly selected as would be a shot aimed at the moon. Even if Diana's too risky shot turns out to be apt by attaining success through sublime archery dexterity, it is still inferior in the particular respect of being so risky and hence so poorly selected.

When we speak of ordinary unqualified knowledge, my thought is that we are implicitly relativizing to the standards imposed by our evolution-derived humanity. These are standards that determine when we consider it appropriate to store beliefs just as a human being, rather than in one's capacity as an expert of one or another sort. Such stored beliefs are to be available for later use in one's own thought or in testimony to others.

Epistemic competence might be posterior to knowledge conceptually, however, while still prior metaphysically.

There's not much to be done about the impossibility. One must instead get rid of the desire.

When I accept someone's testimony, I am thus only a small part of the full seat of epistemic competence, which might include many others in a long chain. My own contribution might then be slight, just through the perceptual and linguistic competence involved in knowing what someone is saying or writing, etc.
