Thrasymachos of Chalcedon

Thrasymachos of Chalcedon was supposed to have worked mainly in Athens, but this is not entirely substantiated. He is credited with intensifying the rhythmic elements in Greek oratory, especially the use of metrical rhythm in prose. He is also credited with a greater emphasis on the expression of emotion through movement as well as gesture.

Thrasymachos of Chalcedon is known through the eponymous character in Plato's Politeia (Constitution). This character argues that justice lies in the benefit of the stronger and therefore injustice is always happening everywhere. From this, he concludes that the gods do not care about humans, as they condone all injustice.
