On this account, Pythagoras was the first but they make a big comeback in the first centuryBC. At this point we begin to see a powerful tendency to combine Plato's ideas with Pythagorean ideas like number to make the love of wisdom 'into a way of life. symbolism. This tendency lives on until the end of pagan Greek philosophy, with As we might expect, Iamblichus also emphasizes Pythagoras' connections with the tradition we nowadays refer to as "": we call the late ancient mathematics, especially .

One of the Neoplatonists who most admired Pythagoras was Iamblichus, who lived in the third to fourth century AD. We'll get to him as a philosopher in his own right in a future volume of this series. I mention him now because he wrote a work called On the PythagoreanW try of Life, which shows the way Pythagoras was perceived by that much later period of Greek philosophy.4 By Iamblichus' day the legend of

26 27 The Pythagoreans believed that the musical had some kind of affinity with, and effect on, the human . Another feat ascribed to Pythagoras-one you can try at home-is using different kinds of music to induce different emotional states. Iamblichus tells how Pythagoras once managed to calm down a ragingly drunk man just by having someone play the right sort of music on a of pipes. The idea that the soul and its states would somehow resonate to music, if you , chimes with the idea that the soul itself might be a kind of harmony. ... The may seem to us strikingly plausible, in its way. On this view, the soul is not some entity separate from the body, but is rather the attunement or proportion that keeps the body in functioning order. Just as a lyre will play badly, or not at all, if its strings are taken out of the correct harmonic tension, so a body will become defective (for instance, ill) or just die if its attunement is disrupted.

... [A]ccording to most Pythagoreans in , the soul and the body are utterly different sorts of thing. The soul is immaterial and probably indestructible. The body is material and will inevitably be destroyed. This view is what philosophers usually mean when they use the word "dualism," and it will be defended by many famous philosophers. Plato and Descartes especially leap to mind. In fact there's good to think that Plato had Pythagoreanism in mind when he developed his particular version of dualism. So we've taken a big step in the direction of understanding Plato's background, or at least the background of one major theme in his philosophy. And now, if you'll again pardon . a pun, we've come full circle, back to the Pythagoreans' .interest in things like circles: numbers, shapes, and all the other objects studied in mathematics. It's no coincidence, I think, that Pythagoreanism is associated both with dualist about the soul and Vl'ith an emphasis on mathematics. The soul postulated by the dualist has a great deal in common with numbers. Both are abstract, immaterial entities and look like they will always exist, assuming they exist at all. How are you going to kill an immaterial soul, or assassinate the number seven? One reason and Pythagoreanism were able to combine _together so easily is that both Plato and the followers of Pythagoras were interested in these stable, immaterial objects. They wanted to get away from the messiness of physical things, with their constant change and their being subject to an infinite number of various features. That certainly isn't the only idea that drives Plato, but it seems to be one of the most important; and it is even more important for later thinkers. who see Pythagoras as the inventor of Platonic philosophy, like our friendIamblichus. ...
