René Descartes

1596–1650

A short biography

The French philosopher and mathematician Descartes investigated knowledge, thinking and the workings of the body. He made the relationship between mind and body a central philosophical question.

He used doubt as a method while seeking a reliable starting point for knowledge. Mathematics and natural philosophy placed his questions about thinking alongside attempts to explain bodily mechanisms.

What does this figure represent in psychology?

His discussions of the certainty of thought and the bodily aspects of emotion belong to psychology’s philosophical background. On the homepage he represents questioning thought.

Distinguishing mind from body left later thinkers a lasting problem about subjective experience and physical processes. His writing on emotion also considers bodily involvement. Students can use these texts to identify the assumptions behind an explanation.

Key concepts

Methodical doubt: examining grounds for a claim. Mind–body problem: explaining relationships between thought and physical processes.

A question for the reader

Distinguish bodily signs of an emotion from its meaning. Does describing them separately prove that they are independent?
