Introduction: Exploring Determinism and Freedom in Philosophy

Defining Determinism and Freedom

• Determinism: The philosophical stance asserting that every event follows natural laws and has a causal explanation.
• Freedom: The capacity of humans to make independent decisions and actions, unaffected by prior events in the universe.

Debating Determinism and Freedom

• Implications: Understanding this debate is crucial for comprehending human agency, moral responsibility, and ethics.

Historical Evolution of Determinism and Freedom

• Theological Determinism: The belief that a god or supernatural power controls all of history.
• Impact: Did not deter humans from seeking control over their lives and societies.
• Compatibilism, Incompatibilism, and Libertarianism: Different philosophical stances on the relationship between determinism and freedom.
