It has been shown above (84-87) that good and truth are universal principles of creation, and are thus present in all created things, in each case in a way depending on their form; and also that good and truth proceed from the Lord not as two, but as one. It follows from these premises that there is a universal sphere of marriage which proceeds from the Lord, pervading the universe from first to last, and so from angels right down to worms. The reason such a sphere of the marriage of good and truth proceeds from the Lord is that it is equally a sphere of propagation, that is, of reproduction and fruitfulness; and this is the same as the Divine providence which keeps the universe in being by a succession of generations.

Now since that universal sphere, marrying good and truth, influences things that receive it in accordance with their form (see 86), it follows that the male receives it in accordance with his own form, that is, in his intellect, since he is an intellectual form. The female too receives it in accordance with her own form, that is, in her will, since she is a form of will arising from her husband's intellect. Since this same sphere is also a reproductive sphere, it follows that this is the source of sexual love.
