## Definition - The [[Philosophy|philosophical]] position that all events, including human actions, are fully determined by preceding causes - Suggests the universe operates according to fixed, knowable laws of nature - Denies the existence of random or uncaused events ## Core Concepts - **Causal chain**: Every event has a cause, forming an unbroken sequence back to the origin of the universe - **Predictability**: In principle, if all causes are known, future states of the system are knowable - **Necessity**: Given initial conditions and laws of nature, outcomes cannot be otherwise ## Key Characteristics - Often associated with materialism and naturalism - Challenges traditional notions of [[Free Will]] - Implies moral responsibility may require redefinition or reinterpretation - Compatible with various metaphysical frameworks (e.g., physicalism, theism) ## Variants - **Hard determinism**: [[Free will]] is incompatible with determinism; humans lack genuine freedom - **[[Compatibilism]]**: [[Free will]] and determinism can coexist if freedom is redefined as acting according to one’s desires - **[[Fatalism]]**: Distinct from determinism; claims events will occur regardless of actions (often conflated but not the same) - **Theological determinism**: Events are predetermined by divine will ## Role in [[Philosophy]] - Central to debates on moral responsibility and ethics - Frames discussions in [[Metaphysics]] and [[Philosophy of Mind]] - Informs scientific perspectives on [[Causality]] and predictability ## Related Concepts - [[Free Will]] - [[Compatibilism]] - [[Fatalism]] - [[Causality]] - [[Stoicism]] (practical acceptance of deterministic order) ## Notable Quotes - "Everything that happens, happens as it should, and if you observe carefully, you will find this to be so." — Marcus Aurelius - "Given the past and the laws of nature, only one future is possible." — Peter van Inwagen
