Democritus’ atomism aims to respond to threats of Parmenidean monism. In so doing, it deploys a familiar epistemological distinction between what is known by the senses and what is known by the mind. This turns out to be a risky strategy, however, leading to inadvertent skepticism with only diffuse and contrary ethical implications. Vasubandhu’s more explicitly metaphysical atomism, by contrast, relies on a different principle to get to its results, and aims to address different concerns. It leaves us with a (...) view that positively implies a concrete mode of practical engagement, and resources for a critical stance. Even if certain atoms end up proven incoherent, there is no danger of slipping into the morally fatal indifference of inadvertent skepticism. For the ethical implications, it matters how one arrives at one’s atomism. (shrink)
