[filed under theme 11. Knowledge Aims / B. Certain Knowledge / 4. The Cogito ]

Full Idea

If any man could be found so frantic as to deny that he thinks, while he is conscious of it, I may wonder, I may laugh, or I may pity him, but I cannot reason the matter with him.

Gist of Idea

If someone denies that he is thinking when he is conscious of it, we can only laugh

A Reaction

An example of the influence of Descartes' Cogito running through all subsequent European philosophy. There remain the usual questions about personal identity which then arise, but Reid addresses those.
