Abstract

In Skeptical idealism says that possibly nothing exists outside my own conscious mental states. Purported refutations of skeptical idealism – whether Descartes's, Locke's, Reid's, Kant's, Moore's, Putnam's, or Burge's – are philosophically scandalous: they have convinced no one. I argue (1) that what is wrong with the failed refutations is that they have attempted to prove the wrong thing – i.e., that necessarily I have veridical perceptions of distal material objects in space, and (2) that a charitable reconstruction of Kant's ‘Refutation of Idealism’ in fact provides a sound refutation of skeptical idealism.
