  On this view, we are left with a skeptical Humean or pragmatic account. Aristotle’s account would be parallel to Hume’s skeptical solution to the problem of induction: We just do proceed as if induction is correct, even though we lack any justification for so doing. Or compare Wittgenstein: “..the end is not an unfounded presupposition—It is an unfounded way of acting.” (On Certainty, Section 110).
