Single Idea 7733

[catalogued under 17. Mind and Body / A. Mind-Body Dualism / 8. Dualism of Mind Critique]

Full Idea

Descartes's claim that mind and body are separate because the first is necessary when thinking and the second isn't, is like arguing 'Superman's strength is indubitable; Clark Kent's strength is widely doubted; so Clark Kent is not Superman'.

Clarification

Should you be leading a sheltered life, you need to be aware that Clark Kent IS Superman

Gist of Idea

Superman's strength is indubitable, Clark Kent's is doubtful, so they are not the same?

A Reaction

I've heard people defend Descartes on this, and Kripke is interesting on the subject, but Descartes had better not be following this pattern of argument, or else a great philosopher would really be presenting an absurdity.
