it’s not easy to say where Leucippus stops and Democritus starts. In the ancient sources many of the atomist doctrines are just ascribed indiscriminately to both of them. Democritus’ interests seem to have been considerably wider, though, and for him we have fragments on ethics as well as atomism. Another thing that seems to be distinctive about Democritus, and which I’ll come back to, is that he draws strikingly skeptical conclusions from his atomic theory.
