Gen Z is now officially the only generation to measure lower than their predecessors in intelligence. A neuroscientist says this is because short videos and summarised texts are being increasingly relied on, but this is not how the human brain works.
Almost everything we know about Socrates is via Plato (Xenophon also mentions him, and there are some satirical references to him in Aristophanes). Plato ran an academy for the offspring of aristocrats, so he had a strong vested financial interest in propagandizing in favor of hierarchy and authority. This is one example.
