Implicit Rationes and Internal Sensations in the Meditationes de Prima Philosophia

Abstract

Descartes states that the cogito is “experienced in oneself” (apud se experiatur) or “felt in oneself” (“il sent en lui-même”), but it has also been pointed out that one only feels through the body. The problem is that, in the Meditations, the cogito was characterized before the existence of the body had been demonstrated. Despite this fact, Descartes seems to have been influenced by certain internal sensations of doubt and certainty. The paper argues that his was possible because those internal sensations are the effect of an implicit ratio: the existence of a non-deceiving God.
