Luck or fortuity is good fortune which occurs beyond one's control, without regard to one's will, intention, or desired result. There are at least two senses people usually mean when they use the term, the prescriptive sense and the descriptive sense. In the prescriptive sense, luck is the supernatural and deterministic concept that there is a force which prescribes that certain events occur very much the way the laws of physics will prescribe that certain events occur. It is the prescriptive sense that people mean when they state that they "do not believe in luck." In the descriptive sense, luck is merely a name we give to events after they occur which we find to be fortuitous.
Cultural views of luck vary from perceiving luck as a matter of random chance to attributing to luck explanations of faith or superstition. For example, the Romans believed in the embodiment of luck as the goddess Fortuna, while the philosopher Daniel Dennett believes that "luck is mere luck" rather than a property of a person or thing.
