ABSTRACT
Aristotle claims that he can even identify a specific starting point for philosophy, that he can list names, acknowledge priorities, and assign roles. The course set by Aristotle reached its final outcome with the affirmation of the idea of 'Presocratics'. By and large, these coincide with the thinkers sequentially listed in the Metaphysics and other Aristotelian texts, by tracing a clear divide between the mythical beginnings of Greek thought, rooted in religious lore, and those developments that according to Aristotle mark the embryonic phase of 'philosophy'. The first testimonies on the Presocratics come from the Presocratics themselves, some of whom refer to the doctrines of their predecessors or contemporaries. Thales introduced elements from the Egyptian world into Greece, particularly in the field of geometry, and from the Eastern, and especially Chaldaean, world in the field of astronomy.
