fatalism

American Heritage® Dictionary of the English Language, Fourth Edition

1. n. The doctrine that all events are predetermined by fate and are therefore unalterable.
2. n. Acceptance of the belief that all events are predetermined and inevitable.

Century Dictionary and Cyclopedia

1. n. The doctrine that all things are subject to fate, or come or go by inevitable predetermination. Fatalism is a doctrine which does not recognize the determination of all events by causes, in the ordinary sense; holding, on the contrary, that a certain foreordained result will come about, no matter what may be done to prevent it. Fatalism is thus directly opposed to necessitarianism, according to which every event is determined by the events which immediately precede it, in a mechanical way. Necessitarianism seems hardly to leave room for final causes, while fatalism is the doctrine that certain results are sure to come in spite of all that efficient causes may do to prevent them. See necessity.
2. n. A disposition to regard everything as the result of or predetermined by fate; the acceptance of all conditions and events as inevitable.
