Some atheists are driven to deny their own existence to maintain naturalism — Rosenberg (The Atheist's Guide to Reality), Harris, Dennett all deny the reality of the self/consciousness. This is self-refuting: someone must be having the illusion.

Alex Rosenberg in The Atheist's Guide to Reality denies his own existence to preserve atheism. Sam Harris and Daniel Dennett say the self/consciousness is an illusion. But as Descartes noted ("I think therefore I am"), someone must be having the illusion — the very fact of having an experience proves a subject exists. Stratton and Winger see this as a reductio ad absurdum of naturalism: "In order to deny the existence of God, they have to deny their own existence." This is where consistent atheistic naturalism leads when followed to its logical conclusions.
