IncompatibilismIncompatibilism is the view that a deterministic universe is completely at odds with the notion that persons have free will, the latter being defined as the capacity of conscious agents to choose a future course of action among several available physical alternatives. Thus, incompatibilism implies that there is a dichotomy between determinism and free will, where philosophers must support at most one or the other, not both.
IndeterminismIndeterminism is the idea that events (or certain events, or events of certain types) are not caused, or are not caused deterministically. It is the opposite of determinism and related to chance. It is highly relevant to the philosophical problem of free will, particularly in the form of libertarianism. In science, most specifically quantum theory in physics, indeterminism is the belief that no event is certain and the entire outcome of anything is probabilistic.
Free willFree will is the notional capacity or ability to choose between different possible courses of action unimpeded. Free will is closely linked to the concepts of moral responsibility, praise, culpability, sin, and other judgements which apply only to actions that are freely chosen. It is also connected with the concepts of advice, persuasion, deliberation, and prohibition. Traditionally, only actions that are freely willed are seen as deserving credit or blame.
