Some scholars see a gap between the existing mythical and the new rational way of thought which is the main characteristic of the archaic period (8th to 6th century BC) in the Greek city-states. This has given rise to the phrase "Greek miracle". But if we follow carefully the course of Anaximander's ideas, we will notice that there was not such an abrupt break as initially appears. The basic elements of nature (water, air, fire, earth) which the first Greek philosophers believed made up the universe in fact represent the primordial forces imagined in earlier ways of thinking. Their collision produced what the mythical tradition had called cosmic harmony. In the old cosmogonies – Hesiod (8th – 7th century BC) and Pherecydes (6th century BC) – Zeus establishes his order in the world by destroying the powers which were threatening this harmony (the Titans). Anaximander claimed that the cosmic order is not monarchic but geometric, and that this causes the equilibrium of the earth, which is lying in the centre of the universe. This is the projection on nature of a new political order and a new space organized around a centre which is the static point of the system in the society as in nature. In this space there is "isonomy" (equal rights) and all the forces are symmetrical and transferable. The decisions are now taken by the assembly of "demos" in the "agora" which is lying in the middle of the city.
