The Phaedo portrays Socrates in a long discussion with members of his inner circle, which leads the dialogue to portray a very different sort of conversation from those found in most of Plato’s other dialogues. The chapter begins by considering why Plato makes Phaedo the narrator of such a significant event: the death of Socrates. The chapter also discusses Socrates’ main interlocutors, Simmias and Cebes. I argue that both are skilled, both make mistakes, and both need to be cautious lest they fall into misology. They are sympathetic to a variety of Pythagorean and Orphic ideas, but are by no means committed followers of Philolaus, a Pythagorean. The end of the chapter turns to the portrayal of Socrates, arguing that Socrates seeks not to be treated as an authority and that the Phaedo presents Socrates’ questions and views as naturally emerging from those in the Socratic dialogues.

This chapter traces a genealogy of pneumatic cosmology, covering the Pythagoreans of the fifth century BCE, the Stoics of the third and second centuries BCE, the Jews writing in Alexandria in the first century BCE and the Christians of the first century CE. Starting from the early Pythagoreans, ‘breath’ and ‘breathing’ function to draw analogies between cosmogony and anthropogony – a notion ultimately rejected by Plato in the Timaeus and Aristotle in his cosmological works, but taken up by the Posidonius and expanded into a rich and challenging corporeal metaphysics. Similarly, the Post-Hellenistic philosopher and biblical exegete Philo of Alexandria approaches the cosmogony and anthropogony described in Genesis (1:1-3 and 1:7) through Platonist-Stoic philosophy, in his attempt to provide a philosophically rigorous explanation for why Moses employed certain terms or phrases when writing his book of creation. Finally, the chapter sees a determined shift in the direction of rejecting pneumatic cosmology for a revised pneumatic anthropogony in the writings of the New Testament: by appeal to the ‘Holy Spirit’ (πνεῦμα ἅγιον), early Christians effectively adapted the Stoic metaphysics of ‘breath’, with its notions of divine intelligence and bonding, to the ecclesiastical project of building a Christian community conceived of as the ‘body of Christ’.

When did kosmos come to mean ‘world-order’? This chapter ventures a new answer by examining evidence in late doxographies and commentaries often underutilized or dismissed by scholars. Two late doxographical accounts in which Pythagoras is said to be first to call the heavens kosmos (in the anonymous Life of Pythagoras and the fragments of Favorinus) exhibit heurematographical tendencies that place their claims in a dialectic with the early Peripatetics about the first discoverers of the mathematical structure of the universe. Xenophon and Plato refer to ‘wise men’ who nominate kosmos as the object of scientific inquiry into nature as a whole and the cosmic ‘communion’ (koinônia) between all living beings, respectively. But Empedocles is the earliest surviving source to use kosmos to refer to a harmonic ‘world-order’ and to illustrate cosmic ‘communities’ between oppositional pairs, realizing the mutual correspondence in the cycle of love and strife. Thus, if later figures posited Pythagoras as the first to refer to the universal ‘world-order’ as the kosmos, they did so because they believed Empedocles to have been a Pythagorean natural scientist, whose combined focus on cosmology and ethics was thought to exemplify a distinctively Pythagorean approach to philosophy.
