As regular readers may know, I am a determinist. I believe that individual agents have no power or ability to self-determine their behavior, and that their behavior is caused by forces over which they have no power. It has been pointed out to me, however, that quantum mechanics calls into question the traditional scientific basis for determinism by arguing that the old classical laws of physics are limited in their power of prediction. Laplace’s demon, the imaginary being that uses infinite information and infinite computing capacity to calculate everything that has ever happened or will ever happen using the physical laws, is not considered viable under modern science. Does this mean anything for my determinism? That’s today’s topic.
