Determinism (Philosophy HL)

The big idea: Drop a glass and it falls — caused by gravity. Feel angry and you snap — caused by tiredness, hunger, a bad day. Determinism says everything works like this, your choices included: each one is the inevitable result of what came before.

If that's right, then the you sitting here — your brain, mood and memories — was shaped by causes stretching back before you were born. And those causes fixed exactly what you'd 'choose'.

Hold onto this: Determinism isn't the claim that choices don't happen. It's that every choice is fully caused — so, given the past, only one outcome was ever really possible.

Here's how the determinist turns 'everything has a cause' into a threat to freedom.

Checkpoint — determinism: The core move: choices are events; events are fully caused; so choices are fully caused. Given everything that came before, only one 'choice' was ever going to happen.

One thinker takes the argument to its boldest conclusion.

The hard determinist: A hard determinist bites the bullet: if every choice is fully caused, then free will is an illusion and no one is ever truly responsible. When you feel you 'could have done otherwise', you're simply missing the hidden causes that made your choice inevitable — like a leaf sure it chose to fall, blind to the wind.

Go further — higher-level insight: Some hard determinists argue this is actually kinder: if criminals couldn't ultimately have done otherwise, we should treat wrongdoing like a medical problem to fix, not a sin to punish. It reframes justice from blame to repair — a strong point to weigh in an essay.
