Maybe we should consider the role the evolving math had on philosophy. Though I am not really sure which had a greater impact on which.

In most agricultural cultures some geometrie was developed for the purpose of dividing the land and defining borders. But it have been the Greeks who developed what we call Mathematics today. That is they looked indepndend of an actual problem into connections in triangels for example. And they saw that one can actually proove absolutely some things, like the famous proposition of Phytagoras.

Since it worked there why shouldn't it work everywhere? So we went from myth teachings in stories that tackle defined human problems to logos a structured approach of how the world and human beings work on an absolute level.

However it is not so easy to set up an independend and consistent theory of everything (what we should know about 2500 years of research)so Plato had a picture of ideals, but had to rely on myth partly, since it was (for the moment) not possible to discern the absolute truth.
