In this episode Tim reviews the Platonic conception of justice and action in the city and in the soul. He then draws an analogy to a musical concert. At a concert many instruments are synthesised, harmonised across a period of time and then drawn together with the crowd and lighting. Perhaps this could be analogous to our lives? We often find ourselves divided into competing desires and responsibilities. Tim suggests that in these cases we can harmonise the parts of ourselves into one and synthesise ourselves with society.
