5011 | There are two ultimate classes of existence: thinking substance and extended substance [Descartes] |
Full Idea: I observe two ultimate classes of things: intellectual or thinking things, pertaining to the mind or to thinking substance, and material things, pertaining to extended substance or to body. | |
From: René Descartes (Principles of Philosophy [1646], I.48) | |
A reaction: This is clear confirmation that Descartes believed the mind is a substance, rather than an insubstantial world of thinking. It leaves open the possibility of a different theory: that mind is not a substance, but is a Platonic adjunct to reality. |
