consider this:
which works are the most popular (also in mainstream philosophy)?
easy to understand shit that makes pseuds feel good or smart but doesn't require high cognitive abilities.
why should that have been different with the greeks?
most of the works from that time are lost, isn't the chance high that only the easy to understand shit survived because it was copied the most?
consider Aristotle for example, he is what in the sense of Nietzsche I would call "feel-good philosophy" for the herd.
what if western philosophy and literature was based on the most basic stuff the greeks had to offer?
this is the problem with worshiping tradition in general. old does not equate good. bad stuff also lasts the test of time.
