My experiences have allowed me to see evidence that there is no conjugial love present in the male sex, but it is only in the female sex, being transferred from this to the male (see 161 above). Reason can add a further proof: the male form is an intellectual one, woman is a voluntary form. An intellectual form cannot be warmed by conjugial heat by itself, but only from the linking heat of someone who has it implanted from creation. Consequently it cannot receive that love, except through having attached to it the voluntary form of a woman; this is also the form of love.

[2] The same point can be further proved by the marriage of good and truth; and in the natural man by the marriage of the heart and the lungs, since the heart corresponds to love and the lungs to understanding. But since most people lack any knowledge of these things, to use them as a proof would shed more obscurity than illumination. It is also due to the transfer of this sphere from the female to the male sex that the mind is fired by merely thinking about that sex. It follows that this too is the source of reproductive formation, and so arousal. For on earth, unless heat is added to light, nothing flourishes or is aroused to bear fruit.
