Jerry Coyne and Determinism

A Video

You can see this video where I look at Jerry Coyne’s recent blog on determinism and the denial of free will, and a couple of scientific papers related to neurons and synapses. 

Sabine Hossenfelder Promotes Determinism

We’ve Learned Nothing Since Laplace

Yesterday theoretical physicist Sabine Hossenfelder became the latest in a long line of smart people to make the absurd claim of determinism (see blog or video), and that therefore there is no such thing as free will. This silliness traces at least as far back as Laplace and is based on the idea that any system evolves from time point 1 to time point 2 according to the laws of nature. As Hossenfelder puts it:

These laws have the common property that if you have an initial condition at one moment in time, for example the exact details of the particles in your brain and all your brain’s inputs, then you can calculate what happens at any other moment in time from those initial conditions. This means in a nutshell that the whole story of the universe in every single detail was determined already at the big bang. We are just watching it play out.

The first problem with Hossenfelder’s sophism is that it is non empirical. We experience free will continually in our personal experience. Hossenfelder’s claim amounts to a denial of untold mountains of evidence. Hossenfelder’s predictable solution is anti-realism. The problem, according to determinists such as Hossenfelder, is that our experience is uniformly false. We may think we have free will, but that is nothing more than an illusion.

But why is that true? Hossenfelder makes the Humean appeal to the laws of nature. They show how systems evolve deterministically, so therefore the data from our personal experience must be false. Hossenfelder fails to see the unjustified leap she has made. She has declared the laws of nature to be authoritative without justification.

Hossenfelder has identified a conflict: our experience says one thing, and the laws of nature say the opposite. Something must give, and Hossenfelder unilaterally and without justification concludes that the laws of nature win out. The fallacy is reminiscent of Hume’s argument against miracles that John Earman demolished twenty years ago.

As if sensing a problem Hossenfelder attempts to justify her leap. She explains that “These deterministic laws of nature apply to you and your brain because you are made of particles,” and that “we know that brains are made of particles.” Furthermore, “the laws of nature that we know describe humans on the fundamental level.” But rather than saving the theory, Hossenfelder is merely digging deeper into the fallacy, as she simply begs the question. These are all non-empirical truth claims that are beholden to the assumption of determinism. She simply asserts these claims, but why should we believe any of them are true?

Yet Hossenfelder is supremely confident in her finding. Drop this free will nonsense, she warns, or “you will never understand how the universe really works.” This is the classic intellectual necessity argument, so common in the evolution literature. In this case it is determinism that is required for scientific progress and truth.

This brings us to the second problem with Hossenfelder’s determinism, which is her many truth claims. As she explains above, “the whole story of the universe in every single detail was determined already at the big bang.” But if that is true then Hossenfelder cannot know anything. Everything she has typed out was, well, pre-determined by some initial conditions and some blind natural laws.

Why should Hossenfelder think for a moment that anything that occurs to her has any correspondence to truth? Above she made the classic intellectual necessity argument but, in fact, it is precisely the opposite. Her determinism undercuts her many truth claims, and knowledge in general.

There would be no reason to think anything we ever generate has any particular truth value. For instance, I could decide to type 2+2=5. In fact, there I did it. But of course, Hossenfelder would say that sentence was all preordained. She also would say it is not true. So certainly preordained sentences are not necessarily true. In fact, for Hossenfelder our notions, thoughts, commitments, and conclusions are merely a consequence of the arrangement of particles in our heads. Why should we think they would be true, if there even is such a thing?

Hossenfelder’s conclusion, that “the whole story of the universe in every single detail was determined already at the big bang. We are just watching it play out” is fitting. For it is the ultimate in meaningless, trivialization of the profound. She is mired in the absurd. Hossenfelder is the best and the brightest—a cutting edge theoretical physicist. The wisest that the world has to offer and look where she has landed. As Paul informed the Corinthians in the introduction of his first letter to them, God made foolish the wisdom of this world.

Religion drives science, and it matters.

Evolutionists Are Now Embracing Determinism and Denying Free Will

His Neurons Made Him Do It

Evolution is the most influential theory in the history of science, but where exactly does it lead? Well aside from eugenics, abortion, population control, euthanasia, anti realism, blackballing of opponents, false histories and atheism, evolution also can lead to determinism. Of course like so many of its metaphysical conclusions, evolution leads to determinism only because determinism first led to evolution. For determinism was one of the planks in the so-called “Enlightenment” period, a century before Darwin. So like the French mathematician Pierre-Simon Laplace from two centuries ago, today a growing number of evolutionists hold to the anti realism belief that free will is an illusion. For Harvard’s Gabriel Kreiman, our actions are governed by our neurons, and how they fire off is like the toss of a coin:

The rules that govern our decisions are similar to the rules that govern whether a coin will land one way or the other. Ultimately there is physics; it is chaotic in both cases, but at the end of the day, nobody will argue the coin “wanted” to land heads or tails. There is no real volition to the coin.

And likewise, there is no real volition is us either. We’re like coins. After all, in experiments the neurons of human subjects showed activity before the subjects felt the urge to action. Ergo determinism. Your actions are the result of neural computations. Kreiman believes this work challenges important Western philosophical ideas about free will. Actually it reinforces important Western philosophical ideas about free will. That’s the problem.
