of course not only religion is causing psychosis, I don't know from what insane and Phi took such strange supposition
Your title,
Origin of psychosis, psychoses, causes, cultural sources, implies that religion is the origin of psychosis. Your opening questions, "Is it possible that religion is causing psychoses ? Is it possible that the same is doing philosophy ?", imply that religion and philosophy are the root cause. You did qualify your statements at the end of the OP, and it's possible that your English grammar was misleading to me. Further, when I mentioned that your OP seemed to be a generalization (in post #4), you ignored my comment rather than clarifying.
I'm willing to drop the generalization argument since you've come back to clarify what your intent was. No worries on that score anymore.
