In the fourth century, Saint Jerome completely rejected the notion that Adam and Eve had sexual intercourse in Paradise. On the other hand, Johannes Scotus Erigena, the great ninth-century theologian, accepted the idea. He believed, moreover, that Adam's virile member could be made to rise like an arm or a leg, when and as its owner wished. We must not dismiss this fancy as the recurrent dream of a man obsessed with the threat of impotence. Erigena's idea has a different meaning. If it were possible to raise the penis by means of a simple command, then sexual excitement would have no place in the world. The penis would rise not because we are excited but because we order it to do so. What the great theologian found incompatible with Paradise was not sexual intercourse and the attendant pleasure; what he found incompatible with Paradise was excitement.

Bear in mind: There was pleasure in Paradise, but no excitement.

Erigena's argument holds the key to a theological justification (in other words, a theodicy) of shit. As long as man was allowed to remain in Paradise, either (like Valentinus' Jesus) he did not defecate at all, or (as would seem more likely) he did not look upon shit as something repellent. Not until after God expelled man from Paradise did He make him feel disgust. Man began to hide what shamed him, and by the time he removed the veil, he was blinded by a great light. Thus, immediately after his introduction to disgust, he was introduced to excitement. Without shit (in both the literal and figurative senses of the word), there would be no sexual love as we know it, accompanied by pounding heart and blinded senses.

In Part Three of this novel I told the tale of Sabina standing half-naked with a bowler hat on her head and the fully dressed Tomas at her side. There is something I failed to mention at the time. While she was looking at herself in the mirror, excited by her self-denigration, she had a fantasy of Tomas seating her on the toilet in her bowler hat and watching her void her bowels. Suddenly her heart began to pound and, on the verge of fainting, she pulled Tomas down to the rug and immediately let out an orgasmic shout.
