Skepticism

In this chapter I sympathetically consider the idea that skepticism is an epistemic virtue. I argue that this depends on whether skepticism is admirable, and articulate three defenses of skepticism as admirable: a Pyrrhonian defense (on which skepticism leads to tranquility), a Cartesian defense (on which skepticism is prophylactic against error), and a liberal defense (on which skepticism counteracts dogmatism and closed-mindedness). I give the liberal defense the most attention: I distinguish skepticism from several species of dogmatism that are sometimes called “skeptical” (e.g. that of “climate change skeptics”), and associate skepticism with political moderation and intellectual independence.
