Phenomenological arguement against descriptive volitionalism-our experience of belief is of something that happens to us, not something we intentionally chose to do.

Logical arguement against descriptive volitionalism-"I believe in P only because I want P to be true". A statement in this form is contradictory, you cease to believe in "P" when you admit that you have no objective reason for it, only a desire for it.
