I must admit to feeling a sceptical gut reaction when I first read about J. B. Kennedy’s brand new article on Pythagorean number theories being embedded in the structure of Plato’s dialogues – a possible key to his unwritten doctrine. I first read about it in The Guardian‘s rather popularizing account. After doing some more searches, and finally checking the original paper published in Apeiron, I am happy to say it looks much more solid than one first expects when hearing something along the lines of “lone scholar x cracking codes in the works of legendary intellectual hero y“.
