Sexual intercourse is a momentary affair, terminating in exhaustion and disgust. If it begins in the spirit, it soon ends in the flesh; i. e., the amative, which is spiritual, is drowned in the propagative, which is sensual. The exhaustion which follows naturally breeds self-reproach and shame, and this leads to dislike and concealment of the sexual organs, which contract disagreeable associations from the fact that they are the instruments of pernicious excess. This undoubtedly is the philosophy of the origin of shame after the fall. Adam and Eve first sunk the spiritual in the sensual, in eating the forbidden fruit; and then, having lost the true balance of their natures, they sunk the spiritual in the sensual in their intercourse with each other, by pushing prematurely beyond the amative to the propagative, and so became ashamed, and began to look with an evil eye on the instruments of their folly.
