Reasoning as Computation

In De Corpore Hobbes first describes the view that reasoning is computation early in chapter one. “By reasoning”, he says “I understand computation. And to compute is to collect the sum of many things added together at the same time, or to know the remainder when one thing has been taken from another. To reason therefore is the same as to add or to subtract” (Hobbes 1655, 1.2). - Thomas Hobbes, 2.4 Reasoning as Computation
