What If You Never Could Have Done Otherwise?

Every decision you've ever made, every choice that felt entirely your own, was the result of a brain state. That brain state was caused by prior brain states, which were caused by your genes and your experiences and the food you ate that morning and the neural pathways laid down in childhood by things you didn't choose. Go back far enough and the causal chain reaches events that predate your existence entirely. The Big Bang, if you want to be dramatic about it.

This is the determinist position, and it's worth sitting with before dismissing. If every physical event is caused by prior physical events, and your brain is a physical thing, then your thoughts and decisions are caused by prior events too. The feeling that you could have done otherwise, that you freely chose the salad over the burger or the kind word over the sharp one, might be exactly that: a feeling, not a fact.

Most people's first response is to reject this. It can't be right. I obviously make choices. I deliberate, I weigh options, I change my mind. The experience of deciding feels nothing like the experience of a rock falling. There has to be something more going on.

But that response, while understandable, doesn't actually engage with the argument. The question isn't whether deliberation feels real. Of course it does. The question is whether that deliberation could have gone any other way, given everything that preceded it.

What Hard Determinism Actually Implies

If hard determinism is true, the implications are significant and uncomfortable. Moral responsibility becomes very hard to justify. If a person couldn't have done otherwise, given their history and their neurology and the circumstances they found themselves in, then punishing them starts to look like punishing a rock for falling. You can prevent future harm, you can protect society, but the notion of someone deserving punishment in any deep sense starts to dissolve.

The philosopher Galen Strawson made a version of this argument precise. To be truly responsible for your actions, you'd need to be responsible for the mental states that caused them. To be responsible for those mental states, you'd need to be responsible for the prior states that caused them. Eventually you run out of road. At some point there's a self that just exists, without having chosen to be the way it is. That self is the foundation of everything that follows, and it was never up to you.

This is the Basic Argument, and it's never been convincingly refuted, only worked around.

Libertarian Free Will and Why It Struggles

One response is to say that humans have a special kind of freedom that escapes the causal chain. Call it libertarian free will, the idea that at least some of our choices are genuinely undetermined, that there's a self that can originate action from outside the network of causes.

The problem is that this is very hard to make coherent. If your choices are not caused by your brain states, your history, your character, what are they caused by? Randomness? Quantum indeterminacy? Neither of those sounds like freedom. A choice that comes from nowhere, that isn't connected to who you are or what you value, isn't really your choice at all. It's just noise.

The philosopher Robert Kane has tried to develop a more sophisticated libertarian view, arguing that we can have genuine freedom at moments of genuine internal conflict, where quantum-level indeterminacy in the brain means the outcome isn't fully determined. But even if the physics works out, it's unclear that this gives us what we wanted. What we wanted was the sense that our choices flow from who we are and that we could have genuinely chosen otherwise. Randomness at the neurological level doesn't obviously deliver that.

Compatibilism and the Redefinition

The most popular position among professional philosophers is compatibilism: the view that free will and determinism are not actually in conflict, because free will doesn't require being outside the causal chain. It just requires acting from your own desires and reasons, without external compulsion.

On this view, the person who chooses the salad freely because they want to be healthy is exercising free will, even if that desire is itself the product of a causal history. The person who chooses the salad because someone is holding a gun to their head is not. The difference that matters is internal versus external constraint, not determinism versus indeterminism.

This is a sensible position and it preserves most of what we care about in everyday life. It's why we rightly treat people differently based on whether they acted under duress, whether they had the cognitive capacity to understand what they were doing, whether their character was their own. These distinctions still make sense in a deterministic world.

But compatibilism doesn't give you everything. It doesn't give you the sense that you could have genuinely done otherwise, all other things being equal. It gives you a pragmatic, workable concept of freedom. Whether that's the real thing or a useful substitute is a question compatibilists tend to sidestep.

What This Changes About Everyday Life

I've found that thinking seriously about this question changes something, even if you can't resolve it.

The case for harsh judgment gets harder. If someone's character, and therefore their behavior, was substantially shaped by things outside their control, then contempt starts to feel less justified. That doesn't mean behavior has no consequences, or that all actions are equally acceptable. But the extra layer of moral disgust, the sense that someone is simply bad and deserves to suffer, becomes harder to sustain when you take seriously how much of who we are was never chosen.

At the same time, the case for self-compassion gets stronger. The things about yourself that you find most difficult to change, the patterns you keep returning to, the ways you fall short of who you want to be, are not simply failures of will. They have histories. Understanding those histories doesn't excuse anything, but it might make the work of actually changing more realistic than the alternative of just trying harder through sheer force of judgment.

The question of whether you have free will probably can't be settled. But the practice of taking it seriously, of noticing the causal texture of your own behavior and the behavior of others, is one of the more useful things philosophy can offer.

It doesn't resolve the metaphysics. But it makes the ethics a little more honest.
