P33: The intellectual Love of God/Nature, which arises from the third kind of knowledge, is eternal.

Dem.: For the third kind of knowledge (by P31 and by IA3) is eternal. And so (by IA 3), the Love that arises from it must also be eternal, q.e.d.

Schol.: Although this Love toward God/Nature has had no beginning (by P33), it still has all the perfections of Love, just as if it had come to be (as we have feigned in P32 C). There is no difference here, except that the Mind has had eternally the same perfections which, in our fiction, now come to it, and that it is accompanied by the idea of God/Nature as an eternal cause. If Joy, then, consists in the passage to a greater perfection, blessedness/flourishing must surely consist in the fact that the Mind is endowed with perfection itself.
