 Atoms in themselves again are space occupying; however, among created things the Muslim theologians also posited things that were in themselves not space occupying, but rather inhered in atoms. Things of this latter sort are the so-called ‘accidents.’ Muslim theologians had argued for the existence of accidents from the fact that atoms as such are similar or homogeneous, and so if there are perceptible differences among bodies (and there clearly are such differences), those differences must be due to differences among the accidents that inhere in the atoms. The Muslim theologians then went on to identify no less than twenty-two different kinds of accidents, which include the obvious ones such as taste, color and smell as well as adhesion, force, power and willing, but also less obvious ones such as life and ceasing to exist.
