Fatalism: The doctrine that what will happen will happen, and nothing we do or do not do will make any difference. It can of course be held either about everything and everybody or in more restricted forms. It is distinguishable from a causal determinism that holds that everything, including everything which we do, is completely caused, but that still leaves room for the possibility that human action may be causally effective in ensuring that this happens rather than that. Leibniz somtimes speaks of fatalism as Mahommedan Fate.
