or to further your self-development, this is a superb book for dipping in and out of. While Heraclitus of Ephesus (535BC – 475BC) might be one of the more enigmatic figures in Greek philosophy, his impact is no less profound. From what we know, he was one of the pioneers of the idea of an ‘ordered universe,’ but was equally preoccupied with the concept of equality between all people. However, it was his focus on the balance between the elements that was to be his critical undoing. Heraclitus’ belief that each element has its place in the order of things may have made him unpopular with the cognoscenti, but it also paved the way for those following in his philosophical footsteps, such as Socrates and Plato.
