 This, however, is not yet an argument for foundationalism as much as an argument against what we might call “inferentialism”—the view that all justification is inferential—for it leaves open the skeptical position that we are not, and could not be, justified in believing anything at all, whether by inference or otherwise. This most radical of all skepticisms seems absurd (it entails that one couldn’t even be justified in believing it). But, strictly speaking, none of this shows that we have non-inferential justification for any of our beliefs, or even that non-inferential justification is possible. At best, it shows only that, if justification is possible, or if we are or could be justified in believing anything at all, then that justification must take a foundationalist structure. The epistemic regress argument for foundationalism thus needs an additional premise, though one that all but the most radical skeptics would accept: that epistemic justification is in principle possible for beings like us.
