As someone that studied philosophy, his work is cited often and is absolutely instrumental in modern theory of mind. His work has seen a resurgence recently due to the explosion of LLMs. I've read 2 or 3 of his books, and he was a brilliant mind with clear & concise arguments. I met many of his collaborators at UCLA, but sadly never the man himself. Either way, his work has had a profound effect on me and my understanding of the world.

Rest in peace.
