George Ellis is professor of complex systems in the Department of Mathematics and Applied Mathematics at the University of Cape Town in South Africa and he has written an essay in defense of the idea of free will. It is a long essay but his argument is really against classical determinism of the Laplacian kind, as can be seen by this statement.
For the sake of argument, let’s suppose I’m wrong. Let’s ignore all these issues and take the deterministic view seriously. It implies that the words of every book ever written – the Encyclopaedia Britannica, Das Kapital, the Harry Potter series – were encoded into the initial state of the Universe, whatever that was. No logical thinking by a human played a causal role in the specific words of these books: they were determined by physics alone.
