Ann Scholl revises the traditional understanding of the role of imagination and sensory perception in Descartess Meditations. Traditionally, Cartesian scholars have focused primarily on sensory perception as the more significant of the two «special» modes of thought. In this work, Ann Scholl describes how a better understanding of Descartess skepticism and his arguments for dualism are reached when imagination instead is understood as the more primary of the two special modes of thought. The result is a fresh reading and interpretation of Descartess most influential work.
