Abstract

Substance dualism is on the move. Though the view remains unfashionable, a growing and diverse group of philosophers endorse it on impressive empirical, religious, and purely metaphysical grounds. In this note, I develop and evaluate one conceptual argument for substance dualism. According to that argument, we may derive a conclusion about our nature from the mere fact that we have the concept of a spirit. The argument is intriguing and fruitful; but I shall contend that it is, nonetheless, unsound.
