We continue our discussion of Whitmarsh's Battling the the Gods: Atheism in the Ancient World. The second part of his book deals with the atheism in Classical Athens (5th-4th centuries BCE). In this episode, some important figures of that time period such as Thucydides (author of the Peloponnesian War), Protagoras, Democritus, Aristophanes, Euripides, Plato, as well as Anaxagoras, Diogoras of Melos, Socrates, and Theodorus of Cyrene and their impact on atheistic thought are reviewed.
