Hey everyone,
I have noticed overtime that us humans sometimes accept concepts that we do not understand well. And that is fine honestly, for tons of reasons. But there are some concepts that… before even talking about understanding, we fail to properly conceptualize. Yet we believe in them. Free will is one of these concepts to me.
Disclaimer: Whenever I think of something, I look for the purest form of the idea. That is what do we mean to express at a core by this word or expression. I am aware that people have their own definitions, but what I am aiming to address here is the purest form of “free will” I was able to identify, which subsequently should underlie most if not all individual definitions that do not straight up change the concept.
There are various ways people define free will. The most straight forward way is “control over one’s actions,” which is something we have. Yes, if that is how you define free will, then we have it. I am controling my fingers to type this very sentence, and every day I perfectly control my body to get by. I am moving according to what I want without problem every single day. And I will continue to do so. The real question is: “Do I choose what I want?” Or “Why do I want what I want?” The problem with free will isn’t “Why did you carry out murder?” But rather “Why did you even want to carry it out?” Given that you would naturally carry anything out controllably… as long as you decide to do so.
At a core it seems to me that we use free will to refer to: “The ability of a thinking agent to make decisions freely, aka uninfluenced.” Not to be confused with carrying out an action freely. Indeed, free will happens in the mind. I perceive it to serve the purpose of achieving near-full absolute responsibility for one’s actions, such that, for instance, justice / punishment (whether divine or human) would be warranted in the absolute.
The problem is the following: it is impossible for an agent to be uninfluenced.
If you disagree with that here is the actual reasoning:
Let’s suppose you have a choice (equivalent to your want) to make between two or more alternatives.
Your choice is based on a natural number x of factors (whether finite or infinite).
Your choice is either predictable / deterministic, (a) or unpredictable (b). Under a deterministic lense, all these factors together fully determine your choice. You may be in control of all the factors leading to your choice, and therefore in hypothetical perfect control of your choice. But were you in control of each and every factor behind those factors? Perhaps, but were you in control of the factors of the factors of the factors (3 layers back)? You will eventually reach a stage where the factors behind your ultimate decision were out of your control (such as when you were a baby). Thus, under determinisim, you cannot have absolute free will.
Under (b), we may not be able to reduce your choice to a number of factors x. Also, there may still be at least one factor behind your choice, but however many they are, it may not be enough to predict your choice. This is equivalent to saying that knowing ALL relevant information is NOT enough to know the outcome (if there is even any information or factor to be known). The only case scenario that I have seen in life where this happens is when randomness is involved. When there is randomness, there can be uncertainty even in the face of perfect knowledge. And if a process is fully random, then there is a complete lack of knowledge regarding its outcome. Thus under (b), your choice is at least partially random, meaning even you would be unable to predict it. That may pass the test of uninfluence, but it voids you of your agency, nullifying the free will of such a choice.
If you disagree with the outcome of (b), then I challenge you to tell me what else could possibly induce unpredictability without it being randomness. Remember, any reasoning, information, or causality / factor of any kind behind your choice hinders absolute free will. Randomness too. What else is out there? I’ll wait.
In short, it is impossible to choose one’s want from scratch, and thus despite perfect control of the actions we carry out, we do not have any complete control over the decisions to carry such actions.
If you did, something in logic and reality would probably break.
This bothers a lot of people because if someone didn’t choose to want bad things, how can you fairly punish them for it? Well, reality doesn’t work mike we want… and justice is a very human concept.
But hey, let’s not despair. If our wants are that uncontrolled, at least once we have them, we can decide what to do to satisfy them. I posit that people constantly choose the best path forward they can come up with (the best path to satisfy their wants based on the efforts they’re willing to put in and based on what they know). But sometimes, we aren’t able to reach what we’re technically capable of. The efforts we’re willing to put in may be too low, and we find ourselves straying from the optimal path we found. To me, the ability to stick with that optimal path is the true free will we should pursue. The one I like to call practical free will. Not some grand impossible cosmic version, but rather a very down to earth attempt at being the best versions of ourselves, and succeeding. The ability to consistently carry out the best actions we can come up with, based on what we happen to want to achieve in life.
