Sabine Hossenfelder today explained why we have no free will and why we shouldn’t worry about it.
She’s right but she missed an important piece of the story.
A quick summary of her essay is that our brain is a computer made of particles governed by the laws of physics that inputs our current state and calculates a decision for what we will do next. Because we don’t know the result of the calculation before it completes, we interpret this as free will, when in fact a computer has no free will.
What’s the main app in our computer? Hossenfelder says it’s to “optimize our well-being”.
Most students of human overshoot would refine Hossenfelder’s description of our main app as the Maximum Power Principle (MPP), which creates our dominant behaviors like status seeking and desiring sex/children.
Varki’s MORT theory adds an important real-time interrupt handler which terminates any calculation that produces an unpleasant result, especially those results that conflict with what the MPP app wants to do.
How else can you explain that elections never even whisper about the elephants in the room like overshoot, resource depletion, ecosystem collapse, debt bubbles, etc.
Not even a whisper. It’s amazing.
These deterministic laws of nature apply to you and your brain because you are made of particles, and what happens with you is a consequence of what happens with those particles. A lot of people seem to think this is a philosophical position. They call it “materialism” or “reductionism” and think that giving it a name that ends on –ism is an excuse to not believe it. Well, of course you can insist to just not believe reductionism is correct. But this is denying scientific evidence. We do not guess, we know that brains are made of particles. And we do not guess, we know, that we can derive from the laws for the constituents what the whole object does. If you make a claim to the contrary, you are contradicting well-established science. I can’t prevent you from denying scientific evidence, but I can tell you that this way you will never understand how the universe really works.
The reason this idea of free will turns out to be incompatible with the laws of nature is that it never made sense in the first place. You see, that thing you call “free will” should in some sense allow you to choose what you want. But then it’s either determined by what you want, in which case it’s not free, or it’s not determined, in which case it’s not a will.
Now, some have tried to define free will by the “ability to have done otherwise”. But that’s just empty words. If you did one thing, there is no evidence you could have done something else because, well, you didn’t. Really there is always only your fantasy of having done otherwise.
If it causes you cognitive dissonance to acknowledge you believe in something that doesn’t exist, I suggest that you think of your life as a story which has not yet been told. You are equipped with a thinking apparatus that you use to collect information and act on what you have learned from this. The result of that thinking is determined, but you still have to do the thinking. That’s your task. That’s why you are here. I am curious to see what will come out of your thinking, and you should be curious about it too.
Why am I telling you this? Because I think that people who do not understand that free will is an illusion underestimate how much their decisions are influenced by the information they are exposed to. After watching this video, I hope, some of you will realize that to make the best of your thinking apparatus, you need to understand how it works, and pay more attention to cognitive biases and logical fallacies.
