Free Will Argument
Posted: Fri Nov 23, 2018 8:51 pm
I've been for a long time anti-free will pro-deterministic. But recently, I've been wondering a lot about this world view of free will - or lack thereof.
This will be a lengthy philosophical post of mine, please take your time to fully understand it, and ask questions.
If the world is one big clock-work universe, and everything is determined from the very beginning to the end, all atoms are positioned in a non-random, determined way.
This means that our brains, which creates our minds from neurological systems consisting of chemical (molecular -> atomic) balances. These balances are subject entirely to the laws of this deterministic universe.
Thus your mind - which creates your will to do stuff, is already fixed and your entire life has been pre-determined from your very beginning.
(of course taking into account environmental stuff, genes etc.).
In other words, your will is not free. But what is free? What does "free" mean? I'll come back this question later.
In quantum physics, there are two major opposing and equally valid theories - The Copenhagen Interpretation where the entire universe is random - fundamentally random (you can't know a particle's position and momentum equally by 100 % - if you want to know for sure its position, its momentum becomes fuzzy and vice-versa). A consequence of The Copenhagen Interpretation is the many-worlds theory - where for every particle's action, change or whatever, the universe splits into different universes in a gigantic multiverse. We just notice one of those universe's which we live in. There could be one where you are the president of U.S. and another where you're a prisoner in China.
This was made as an explanation for the infamous double-slit experiment where particles seem to go through both slits as a wave, independently of those particles being fired with several minutes apart. It still creates the wave/interference pattern on the screen.
- And then there is the Bohmian Mechanics - after the de-Broglie-Bohm Pilot Wave theory.
It says that particles are real - they have definite position and momentum, but they are carried by pilot waves - ultimately they are all subject to the Universal Wave Function. Some argues this is against the Bell Theorem - a no-go theorem stating that local hidden variables cannot exist. But it says nothing about global/universal hidden varariables. If you abandon locality, you have perfectly well defined and deterministic theory that is consistent with making the same predictions as the Copenhagen Interpretation. It also produce surreal trajectories - predicted by the pilot waves - and there is evidence for this.
But even if the Copenhagen "True Randomness"-"Many Worlds" Interpretation is real, it still leaves you without a "free" will. After all, you are still subject to the bouncing-off atoms making up your mind and creating the neuro-chemical signals creating your consciousness, you will and actions.
It's just that they happen to be fundamentally random then. But still no free will.
But what exactly is Free Will? What is "free"? What is "Will"? If you can define those terms, you are better equipped with a clear-cut answer to the question.
If you feel an urge to open a door - that urge is the will. You had the will to open the door.
But was it free? If someone prevented you from opening the door, you certainly had the will - but not the freedom to open it.
So logically speaking, if you feel the will to open the door, and succeed - you must have had the freedom to act on your will. Hence Free Will.
Surely, your neurological atoms caused your will. But why does that matter to the freedom? After all, if you cannot define freedom, you cannot argue we don't have it.
