Quine on Hume

Quine, as quoted in the heading, was not contemplating the Sensible Knave. The quote is from "Epistemology Naturalized" in Ontological Relativity and Other Essays (1969) and addresses Hume's epistemic skepticism. The Sensible Knave, on the other hand, shares Hume's skepticism about the possibility of a rational basis for moral beliefs.
