Free will

I keep running into the Ajivikas

(In the books I’m reading. Not like, down to Stop&Shop or anything)

and I keep seeing the same response: they must not have been completely adamantly against free will, because how could you found a movement on that?

To which, speaking as a person who doesn’t believe in free will myself, I say two things:

-First: Have you met Reverend Calvin here?

-Second: Even if you think the idea of free will is utter birdshit, you still have to do something. And if that something turns out to be create an atheist ascetic religious movement, well: looks like that’s what you had no choice but to do.
