Abstract
Peter Klein has taken Aristotle’s regress argument for foundationalism as a point of departure for developing a view he calls ‘infinitism’. In this paper, I offer a critique of Klein’s view. I argue for three main conclusions. First, Klein’s response to the regress argument for foundationalism is neither infinitism nor foundationalism but a distinct position I call the “unjustified foundations” view. Second, Klein’s “unjustified foundations” view is subject to some serious problems that make it inferior to foundationalism. Third, Klein’s objections to foundationalism fail to knock it from its place of superiority over the “unjustified foundations” view. Before defending these three conclusions in sections 3-5, I begin with an account of the regress argument for foundationalism in section 1 and with a brief presentation of Klein’s views in section 2.
