Question 1

What is the difference between Determinism and Fatalism?

Accepted Answer

Determinism grounds outcomes in prior states plus natural law; fatalism says you are powerless to do anything other than what you actually do, and the classical arguments for it run either on logical necessity or on the existence and nature of God, not on natural law. The practical difference is enormous — under determinism, deliberating changes the outcome, because the deliberation is part of the cause.

Question 2

Are Determinism and Fatalism the same thing?

Accepted Answer

Fatalism is clearly separable from determinism. Fatalism says the outcome arrives whatever you do; determinism says your doing is one of the causes it arrives through. Under determinism your deliberation is a real link in the chain — it just has causes of its own.
