אתיקה, חלק V, משפט 33

The third kind of knowledge is eternal (V. xxxi. I. Ax. iii.); therefore (by the same Axiom) the love which arises therefrom is also necessarily eternal. Q.E.D.

Although this love towards God has (by the foregoing Prop.) no beginning, it yet possesses all the perfections of love, just as though it had arisen as we feigned in the Coroll. of the last Prop. Nor is there here any difference, except that the mind possesses as eternal those same perfections which we feigned to accrue to it, and they are accompanied by the idea of God as eternal cause. If pleasure consists in the transition to a greater perfection, assuredly blessedness must consist in the mind being endowed with perfection itself.
