About Plato: he did not know about many things, including evolution and neurons, so he believed in a totally bogus view of reality and human existence. He imagined that numbers and geometric shapes existed as the fundamental substratum of reality because he did not know that mathematical abstractions are created by human brains. Had he known about evolution, he would have been able to realize that none of us would be here if our brains did not provide us with quite accurate information about the world.
