159. (3) A wife's will unites itself with her husband's understanding, and the husband's understanding in consequence unites itself with his wife's will. The reason is that a male is born to become a form of understanding, and a female to become a form of will that loves the understanding of the male. It follows from this that the conjugial union is a union of the wife's will with the husband's understanding, and a reciprocal union of the husband's understanding with the wife's will. Everyone sees that there is a very close union between understanding and will, and that the union is such that the one faculty can enter into the other and find delight from and in that union.
