The doctrine that all things are subject to fate, or that they take place by inevitable necessity.
The psychological counterpart of determinism: the belief that the future will happen anyway, and there's nothing that anybody can do about it. It follows that it's useless to try and improve the human condition. The concept of fate is not quite so fatalistic: the endpoint may be predetermined, but the routes to it may not. See also determinism.
Events are predetermined by a cosmic purpose, plan, or will. Whatever is foreordained will occur no matter what. Human control is limited to attitude (e.g., resignation to the will of God). Nothing happens by accident or chance.
