Quentin Smith used to be a prolific philosopher, but, if PhilPapers.org is accurate, it has been many years since he’s published anything new. He used to have his own website, which is now gone. His faculty page at WMU, which used to contain his vita and links to papers, is now stripped down to very minimal content. People tell me they’ve been unable to get ahold of him.
I hope he is okay. If anyone has any information (and they are allowed to share it), please post a comment below or send me a private email.
(Ryan M posted essentially the same question in a comment on my post, “What Happened to Philo?” I had already planned to write this post as a separate post but I want to give him credit for independently having the same question.)
