Hegel's Double Negation Paradime

i've had a look at his lectures on the history of philosophy and he doesi touch on some of this stuff, but it doesn't seem like he has a lot of access to those texts. But none the less, the sort of a double negation paradime starts to emerge a somewhere between roughly 408 hundred or 900 years before hagel. So here we have the early s, you know, giving rise to implicitly the concept of negation, without making it an explicit concept or abstraction.
