computationism

Although computers are a twentieth-century invention, computationism is much older, descending from Newton's contemporary Leibniz (and, arguably, more remotely from the Pythagoreans). It holds that everything is rationally intelligible only so far as it instantiates mathematical rules and ratios. As understood by Leibniz and his followers, computationism was explicitly hostile to all versions of materialism.
