‘Let none but geometers enter here’
While Plato was publishing his dialogues, his Academy was researching and teaching sacred arithmetic and geometry. This explains the constant references to mathematics in the dialogues.
At the Platonic Academy of Melbourne we believe that a full understanding of Plato’s philosophy is only achieved by seeing and experiencing just how it was informed by the mystical mathematics practiced at Plato’s original Academy. This is why this very special course mixes discussion of the philosophical teaching with hands-on geometric drawing.
Join us for six small-group weekly sessions consisting of a talk, a discussion and then some drawing with compass and ruler.
For geometry beginners. But not for beginners with Plato, who should be Reading Plato first.
