Re: The Free Will Straw Man

There's also another straw man that I'd like to point out: responsibility.

No, nobody thinks this way. It seems that what you are positing is a deterministic clockwork universe in which everything could be traced back to a root cause. Knowing that cause would let us predict the entire future, including peoples' actions. Are you kidding me? It's called determinism, and it'...
