indeterminism

…extreme alternative to determinism is indeterminism, the view that at least some events have no deterministic cause but occur randomly, or by chance. Indeterminism is supported to some extent by research in quantum mechanics, which suggests that some events at the quantum level are in principle unpredictable (and therefore random).…

…is that of randomness, or indeterminacy. In general, the theory predicts only the probability of a certain result. Consider the case of radioactivity. Imagine a box of atoms with identical nuclei that can undergo decay with the emission of an alpha particle. In a given time interval, a certain fraction…

…even some ancient materialists were indeterminists, and a modern physicalist materialism must be indeterministic because of the indeterminism that is built into modern physics. Modern physics does imply, however, that macroscopic bodies behave in a way that is effectively deterministic, and, because even a single neuron (nerve fibre) is a…
