is there free will?

[The Stranger]

You keep starting with the assumption that having free will must mean that determinism is false...

Consider:

1) Unless there are special circumstances, people should be held morally responsible for their actions
2) If you can't reasonably foresee the consequences of your action, that would be one such special circumstance (e.g. if I pat you on the back and you die, I should not be called a murderer)
3) In order for you to be able to reasonably foresee the consequences of your action, the world can't be random, it needs to be causally determined

Therefore: Moral responsibility requires causal determinism.
.

actually that is why that kind of moral responsibility requires causal determinism. because that kind of moral responsibility is based on its consequenses and not on its intentions. moral responsibility based on intentions doesnt require causal determinism.
