Socrates and Platonic Forms The presocratic philosophers discussed the relationship between phusis (nature, from the root to grow) and nomos (law, custom). [Added: What is by nature vs what is by convention.] — Fooloso4
This is the
Eleatic philosophy.
"Eleaticism, one of the principal schools of ancient pre-Socratic philosophy, so called from its seat in the Greek colony of Elea (or Velia) in southern Italy. This school, which flourished in the 5th century BCE, was distinguished by its radical monism—i.e., its doctrine of the One, according to which all that exists (or is really true) is a static plenum of Being as such, and nothing exists that stands either in contrast or in contradiction to Being. Thus, all differentiation, motion, and change must be illusory. This monism is also reflected in its view that existence, thought, and expression coalesce into one."
Anaxagoras belonged to this school. In identifying
mind as the prime motive force in the world, he was in keeping with the a worldview that goes back to the end of the Bronze Age. What's missing from this view to make it what we would think of as science, is the "clockwork" conception of the universe that first starts with Aquinas and progresses to Newton. They wouldn't have understood our distinction between religion and science, and so it's a mistake to project that into what Plato says.
Socrates criticizes those who cite the authority of the poets because they are unable to give an account. Mythos without logos. Since the poets, most notably Homer and Hesiod, are the source of the teachings about the gods, there is seen in Plato a conflict between religion and science. In the Apology, Anaxagoras' claim that the sun is a stone and not a god, is falsely attributed to Socrates and is used as the basis of the charge of atheism against him. It is at its heart a conflict between religion and science. — Fooloso4
You're confusing the Athenian state for a religious authority. It wasn't. The law Socrates broke was created by Solon and was simply an admonishment against failing to show respect for the gods. The grudge the Athenians had against Socrates was not based on a science/religion controversy. It was that they thought his style of teaching produced derangement among the young. There were no religious institutions of the kind we know today. There were only various temples and the Oracle. Opposition to mystery religions can be thought of as an impetus for more rational consideration, but that's far from, again, what
we would think of as a war between science and religion.
Does human nature change over time? — Fooloso4
In some ways, yes. But I'm not suggesting that residents of the iron age were from a different species. I'm simply pointing out that the worldview of people 2400 years ago was missing elements critical to a mechanistic outlook which underpins our conception of physicality and science.
