[catalogued under 17. Mind and Body / E. Mind as Physical / 1. Physical Mind]

Full Idea

Psychophysical identity is a two-way street: if all mental properties are physical, then some physical properties are mental; but then all physical properties might be mental, or every property of everything might be both physical and mental.

Gist of Idea

Psychophysical identity implies the possibility of idealism or panpsychism


David Lewis (New work for a theory of universals [1983], 'Min Mat')

A Reaction

I suspect that this is the thought that has impressed Galen Strawson. The whole story seems to include the existence of 'mental properties' as a distinct category. This line of thought strikes me as a serious misunderstanding.
