I don’t have a problem with having a good understanding of classics (liberal arts is a category that far encompasses more than just classical education, though).

I do have a problem with blindly assuming Plato/other ancient philosophers were some sort of omniscient super-intelligence we should blindly follow, which I do see happen with some regularity in my own life.

Plato et al might’ve been the start of our modern understanding of ethics, but the concept of a moral life or epistemology certainly didn’t stop with him!
