Single Idea 3622

[catalogued under 11. Knowledge Aims / B. Certain Knowledge / 5. The Cogito]

Full Idea

When someone says 'I am thinking, therefore I am, or I exist', he does not deduce existence from thought by means of a syllogism, but recognises it as something self-evident by a simple intuition of the mind.

Gist of Idea

The Cogito is not a syllogism but a self-evident intuition
