In philosophy, Greek philosophy refers to the love of knowledge views of the ancient Greeks, oft divided by the pre-Socratic era, i.e. philosopher before Socrates (469-399BC), whose works only exist in fragments, the longest being fragment 17 of Empedocles, and post-Socratic.

The following shows the general genealogy of the 72+ main Greek philosophers and their thinking — originating with the great sage Thales, who was the first Greek to take it upon himself to study abroad, in Egypt, i.e. to learn Egyptian philosophy (logic based on Egyptian mythology, which is based on astro-theology) — the main schools of Greek philosophy, and some of the transition thinkers going into Roman philosophy:

Quotes
The following are related quotes:

“Empedocles professes to obtain all that Anaxagoras obtains from his innumerable principles.”
— Aristotle (c.322BC), Physics (§1.6:189b16)

“Thales is the father of Greek philosophy.”
— Aristotle (c.320BC), Publication [1]

“Greeks, thirsting for knowledge, sought the Egyptian priests for instruction. Thales, Pythagoras, Oenopides, Plato, Democritus, Eudoxus, all visited the land of the pyramids. Egyptian ideas were thus transplanted across the sea and there stimulated Greek thought, directed it into new lines, and gave to it a basis to work upon.”
— Florian Cajori (1991), A History of Mathematics (pg. 15)
