Determinism is a major concept in metaphysics concerned with whether events unfold according to prior causes and conditions. In deterministic frameworks, an event occurs because preceding circumstances, laws, or causal relationships make that outcome follow from what came before. The concept is closely connected with causation, natural law, agency, responsibility, and free will, and it raises questions about whether human choices can be genuinely free if actions are part of a continuous causal chain. Philosophical debates often examine whether determinism and free will are incompatible or whether some form of meaningful choice can exist within a determined order.
