Mecca Chiesa notes that the probabilistic or selectionistic determinism of B. F. Skinner comprised a wholly separate conception of determinism that was not mechanistic at all. Mechanistic determinism assumes that every event has an unbroken chain of prior occurrences, but a selectionistic or probabilistic model does not. Western tradition
In the West, some elements of determinism have been expressed in Greece from the 6th century BCE by the Presocratics Heraclitus and Leucippus. The first notions of determinism appears to originate with the Stoics, as part of their theory of universal causal determinism. The resulting philosophical debates, which involved the confluence of elements of Aristotelian Ethics with Stoic psychology, led in the 1st–3rd centuries CE in the works of Alexander of Aphrodisias to the first recorded Western debate over determinism and freedom, an issue that is known in theology as the paradox of free will. The writings of Epictetus as well as middle Platonist and early Christian thought were instrumental in this development. Jewish philosopher Moses Maimonides said of the deterministic implications of an omniscient god: "Does God know or does He not know that a certain individual will be good or bad? If thou sayest He knows, then it necessarily follows that [that] man is compelled to act as God knew beforehand he would act, otherwise Gods knowledge would be imperfect." Newtonian mechanics
Determinism in the West is often associated with Newtonian mechanics/physics, which depicts the physical matter of the universe as operating according to a set of fixed laws.
For example, Louis Althusser, a structural Marxist, argues that the state, in its political, economic, and legal structures, reproduces the discourse of capitalism, in turn, allowing for the burgeoning of capitalistic structures. Proponents of the notion highlight the usefulness of structural determinism to study complicated issues related to race and gender, as it highlights often gilded structural conditions that block meaningful change. Critics call it too rigid, reductionist and inflexible. Additionally, they also criticize the notion for overemphasizing deterministic forces such as structure over the role of human agency and the ability of the people to act. These critics argue that politicians, academics, and social activists have the capability to bring about significant change despite stringent structural conditions. With free will
Philosophers have debated both the truth of determinism, and the truth of free will. This creates the four possible positions in the figure. Compatibilism refers to the view that free will is, in some sense, compatible with determinism. The three incompatibilist positions deny this possibility. The hard incompatibilists hold that free will is incompatible with both determinism and indeterminism, the libertarians that determinism does not hold, and free will might exist, and the hard determinists that determinism does hold and free will does not exist. The Dutch philosopher Baruch Spinoza was a determinist thinker, and argued that human freedom can be achieved through knowledge of the causes that determine our desire and affections.
