Philosophers Who Support Determinism
Determinism is the philosophical view that all events, including human actions, are determined by preceding causes and natural laws. This perspective has been supported by various philosophers across different historical periods, from ancient times to modern debates in metaphysics and free will.Below are some of the most influential philosophers who have defended determinism in various forms:
Ancient and Classical Determinists
Democritus (c. 460–370 BCE) – The Atomist View
Key Idea: Materialistic DeterminismArgument: Democritus, an early Greek philosopher, proposed that everything in the universe, including human thought and action, is composed of atoms moving according to strict physical laws. Since human decisions arise from physical interactions of atoms, free will is an illusion.
The Stoics (3rd Century BCE – 2nd Century CE) – Fate and Natural Order
Key Idea: Logical and Cosmic DeterminismArgument: Stoic philosophers like Chrysippus argued that everything happens according to divine reason or logos, a rational principle governing the cosmos. Even human choices are determined by this universal order, making free will a misunderstanding of necessity.
Medieval and Early Modern Determinists
Baruch Spinoza (1632–1677) – Necessitarianism
Key Idea: God and Nature as a Single Determined SystemArgument: Spinoza’s metaphysics denies free will entirely. He argued that humans, like everything else, are determined by the necessary order of nature. According to Spinoza, free will is an illusion because our choices are caused by prior conditions, extending all the way back to the nature of existence itself.
Quote:
"Men think themselves free because they are conscious of their actions but ignorant of the causes by which they are determined."
Pierre-Simon Laplace (1749–1827) – Laplacian Determinism
Key Idea: Causal and Scientific DeterminismArgument: Laplace applied determinism to physics, proposing that if someone (often referred to as Laplace’s Demon) knew the exact state of every atom in the universe, they could predict every future event. This suggests that free will is merely a byproduct of human ignorance of causal chains.
Quote:
"We may regard the present state of the universe as the effect of its past and the cause of its future."
19th and 20th Century Scientific and Philosophical Determinists
Arthur Schopenhauer (1788–1860) – Psychological Determinism
Key Idea: "Man can do what he wills, but he cannot will what he wills."Argument: Schopenhauer argued that human actions are determined by character and external influences. While people feel like they make free choices, those choices are dictated by their inherent psychological nature and past experiences.
Quote:
"A man can surely do what he wants to do. But he cannot determine what he wants."
Karl Marx (1818–1883) – Economic Determinism
Key Idea: Historical Materialism and Social DeterminismArgument: Marx viewed human behavior as determined by socio-economic conditions. People's beliefs, ideologies, and choices are shaped by economic structures and class relations, meaning individual freedom is constrained by historical and material conditions.
Quote:
"It is not the consciousness of men that determines their being, but their social being that determines their consciousness."
Sigmund Freud (1856–1939) – Psychological Determinism
Key Idea: Unconscious Drives Determine BehaviorArgument: Freud suggested that human thoughts and behaviors are determined by unconscious psychological forces, childhood experiences, and repressed desires. Thus, free will is an illusion since individuals are largely unaware of the true causes of their actions.
B.F. Skinner (1904–1990) – Behaviorism and Environmental Determinism
Key Idea: Behavior is a Product of ConditioningArgument: Skinner argued that human actions are entirely shaped by reinforcement and conditioning. Since behavior is a response to external stimuli, free will is merely an illusion created by the complexity of environmental influences.
Quote:
"A person does not act upon the world, the world acts upon him."
21st Century and Contemporary Determinists
Sam Harris (1967–Present) – Neuroscientific Determinism
Key Idea: Free Will is an Illusion Based on NeuroscienceArgument: Sam Harris argues that neuroscientific research shows our brain makes decisions before we are consciously aware of them. Since our thoughts and choices emerge from prior brain states and biological processes, we do not have genuine free will.
Quote:
"Free will is an illusion. Our wills are simply not of our own making."
Determinism in Science and Physics (Einstein, Hawking, etc.)
Key Idea: Physical Laws Govern EverythingArgument: Albert Einstein believed that the universe operates under strict causal laws, leaving no room for free will. Similarly, Stephen Hawking suggested that everything, including human behavior, is governed by physical and mathematical principles.
Einstein's Quote:
"Everything is determined, the beginning as well as the end, by forces over which we have no control."
Final Thoughts: Is Determinism the Ultimate Truth?
Determinism remains one of the most debated topics in philosophy and science. While many philosophers and scientists argue for determinism, others support compatibilism (which tries to reconcile determinism and free will) or libertarian free will (which argues for genuine choice and agency).However, what remains clear is that determinism has shaped our understanding of human behavior, consciousness, and the nature of reality itself!
What do you think? Do we truly have free will, or is everything already determined?
