## Definition - The principle that **events occur as a result of causes**, forming a chain of cause-and-effect relationships - Foundational to [[Philosophy|philosophical]], scientific, and everyday reasoning - Used to explain why things happen, allowing for prediction and control ## Core Concepts - **Causal chain**: Events are linked in a sequence where earlier states bring about later states - **Necessity vs. contingency**: Some causes produce inevitable outcomes, others only probable ones - **Correlation vs. causation**: Distinguishing true causal relationships from mere association - **Counterfactual dependence**: If event A had not occurred, event B would not have followed ## Key Characteristics - Central to [[Determinism]]: all effects are rooted in prior causes - Explored in both metaphysical and empirical frameworks - Requires distinguishing direct causes from contributing or background factors - Subject of debate in [[Philosophy]] of science (e.g., Hume’s skepticism) ## Historical Perspectives - **Aristotle**: Fourfold framework (material, formal, efficient, final causes) - **David Hume**: Denied direct [[perception]] of causation; argued it’s inferred from constant conjunction and habit - **Modern science**: Treats causality in probabilistic or law-like terms, often via models and experiments ## Role in [[Philosophy]] & Science - Provides the foundation for scientific inquiry and prediction - Shapes discussions of moral and legal responsibility - Informs debates about [[Free Will]] and [[Determinism]] ## Related Concepts - [[Determinism]] - [[Compatibilism]] - [[Aristotle's Four Causes]] - [[Empiricism]] - [[Counterfactuals]] ## Notable Quotes - "All events seem entirely loose and separate. One event follows another, but we can never observe any tie between them." — David Hume - "Every effect has a cause." — Principle of Sufficient Reason
