Identity theory skepticism

by Neil Rickert

Identity theory or, in full, mind-brain identity theory, is the philosophical thesis that the mind can be identified with the brain.  This is often stated in the form “mental states are identical to brain states.”

I find the thesis puzzling.  Perhaps that’s partly because it doesn’t make sense to me.  That’s because I have trouble making sense of “mental state” and of “brain state”.  I find it far from clear what either of those means.  So I am puzzled that people want to say that there is an identity between two confusing things.

Presumably, part of the motivation for identity theory, is to have an answer for proponents of dualism.  But we surely don’t need identity theory for that.  It should suffice to claim that activity normally attributed to the mind is the result of what is happening in the brain.

A music analogy

Here’s a somewhat analogous situation.  We often discuss music in terms of the pitch (or note) being played, or the combination of notes in a chord.  We might perhaps talk of that as the harmonic state of the music.  If the music is being played on a piano, we could also talk of the physical state of the piano.
