Triads I'll take a stab at the paragraph about "love disporting with itself".
The line is from parapgraph 19 of the Preface to the Phenomenology as it appears on Marxist Internet Archive.

Hegel thinks philosophy should be "science". So a view of philosophy that sinks into "mere edification" is falling short of what philosophy should be.
He might be rebutting a certain current of opinion.
I'll try to interpret the idea of "love disporting with itself". Aristotle has a view that the highest experience was "theoria" which means "contemplation".
To Aristotle, God is eternally contemplating Godself. This divine navel gazing played a role in his system and partly explained the motion of heavenly bodies.
So "love disporting with itself" sounds to me like a reinterpretation of that Aristotelian idea.
But I think what Hegel is saying is that in order to avoid sinking to the level of "mere edification" this has to incorporate the "negative".
