Episode 17: The Enigma of Pythagoreanism

The sources about Pythagoras seem to tell us everything and nothing; we have a wealth of information from classical and late-antique sources, but, as we saw last week, when we try to sift through it all, we come up with very few writings about Pythagoras himself which we can confidently say tell us about him as he was historically, before the overlay of Platonistic interpretation which coloured nearly all post-Platonic reading of Pythagoras and led to the later currents known as ‘Neopythagorean’. The same is not true for Pythagoreanism. We have the fragmentary writings of one of the philosophic Pythagoreans of the fifth century BCE, Philolaos of Croton, who really was more or less what we think of when someone says ‘Pythagorean philosopher’: he saw mathematical ratios as key constituents of reality, privileging number and harmony as ontological principles. He investigated musical harmony, mathematics, and cosmology. Great.

But how do we get from Pythagoras and his earliest followers, whose way of life seems to have had very little to do with mathematics and everything to do with magic and mystery, to later thinkers like Philolaos, with their mathematical and harmonic concerns? That is the story we try to tell in this episode. It is a story with some holes in it, because our evidence is patchy, but the good news is that it involves a political takeover in southern Italy by the Pythagorean sect, followed by a massacre, which is more than you can say for most history of philosophy.
