Determinism
the philosophical and scientific idea that every event, choice, and action is the inevitable result of prior events combined with the laws of nature. In a purely deterministic universe, complete knowledge of the present state and all physical laws would allow an observer to predict the future with 100% accuracy. [1, 2, 3, 4]
Key Forms of Determinism
- Causal/Nomological: Every physical effect follows strictly from preceding causes under natural laws.
- Biological/Psychological: Human behavior is shaped entirely by genes, brain chemistry, or prior psychological conditioning.
- Theological: All events are pre-ordained by an omniscient or all-powerful deity. [1, 2, 3, 4, 5]
The Free Will Debate
- Hard Determinism: Holds that determinism is completely true and that free will is an illusion, meaning people cannot be truly morally responsible for their actions. [1, 2]
- Compatibilism (Soft Determinism): Argues that free will and determinism can peacefully coexist if "free will" is redefined as acting according to one's own internal desires without external coercion. [1]
- Opinions on Meaning and Morality: As discussed on platforms like r/askphilosophy, opinions are mixed regarding life's value under determinism; many thinkers argue that a lack of absolute free will does not destroy human connection, personal growth, or ethics. [1]
