No philosophy survives sticking a crowbar into your own brain.
Hmm... The complaint was that Psyclobin (for example, amongst other everyday occurrences) causes one to see things that you should not believe in. I'm not sure where the analogy holds with a crowbar, or else what point you were trying to make.
The philosophy does not survive in the sense that it is instantiated in ones brain and the brain has been destroyed. But the crowbar experiment does not thus show that the beliefs thus destroyed are false.
