The differences in these conclusions possibly reflect differences in the economy, social order, and the environment of the different civilisations. This essay shall be primarily concerned with the developments in presocratic thought, specifically that of the Ionian rationalists.
For prior to the development of Greek civilisation, although men no doubt speculated on the world beyond their immediate experience, no records of their enquiries survive.
This study shall start by briefly looking at the forerunners of philosophical cosmology, with emphasis being placed upon the writings of the epic poets Homer and Hesiod .
