Abstract

Descartes's dualism did not result from Cartesian doubts, Christian beliefs, from a bias against animal nature, or from a conflict of reason and emotion. In fact, Descartes's dualism was the very fruitful product of the mechanistic conception of causality with which the French philosopher sought to replace the souls, qualities and intelligences contemporaries put forward as alternatives for the outdated Aristotelian principles of matter, form and privation. Descartes's naturalistic turn in physiology and physics not only formed the basis for his dualistic metaphysics; it still bears fruit in the work of scientists such as Antonio R. Damasio today. Descartes gave scientists the paradoxical instruction to describe nature without reference to human experience
