Determinism in philosophy
From Geography
Determinism (specifically causal determinism) is the concept that events within a given paradigm are bound by causality in such a way that any state (of an object or event) is, to some large degree, determined by prior states.
Hence "determinism" is the name of a broader philosophical view that conjectures that every type of event, including human cognition (behaviour, decision, and action) is causally determined by previous events. In philosophical arguments, the concept of determinism in the domain of human action is often contrasted with free will. The argument called indeterminism (otherwise "nondeterminism") negates causality as a factor and contradicts deterministic argument.
Determinists believe the universe is fully governed by causal laws resulting in only one possible state at any point in time. With numerous historical debates, many varieties and philosophical positions on the subject of determinism exist, most prominently the free will debates involving compatibilism and incompatibilism. Predeterminism proposes there is an unbroken chain of prior occurrences back to the origin of the universe.
Determinism should not be confused with self-determination of human actions by reasons, motives, and desires, or with predestination, which specifically factors the existence of God into its tenets.
