Full Idea
I hold a view of mind/brain relations that is a form of causal reduction (mental features are caused by biological processes), but does this imply ontological reduction? (…No!)
Gist of Idea
If mind is caused by brain, does this mean mind IS brain?

A Reaction
What exactly is his claim? Presumably 'causal reduction' implies identity of (philosophical) substance. This seems to imply 'emergence' in a rather old-fashioned and dramatic way, though elsewhere Searle denies this.
