That's a stretch, but we can certainly argue that we mostly validate and refine ideas that have been around for a while. After all we have hundreds thousands years of human knowledge, most of it forever gone. It's not like we only started thinking after the Illuminism, or even ancient Greek.
Well the "ancients" did know everything. As do I. No, really, I know every conceivable thing! It's just knowing which things I know are right that's the hangup.. Everyone has hindsight, but few are blessed with foresight :\
