‘Time was’, wrote William, ‘when the corrupt love of the flesh had its masters, who were so skilled in their subject that the most famous of them was constrained, even by the lovers and companions of his depravity, to recant by praising the opposite of what he had originally taught’. The reference to Ovid is clear enough. The Ars Amatoria, to a monastic mind of the twelfth century, is the testament of a pastmaster in corruption and perversity, of a persistent follower of the bent of fallen nature, which is away from God, back to the flesh, and downward to the earth.
The due order of nature, for William, is the upward direction that fire takes, for the soul is created to look heavenward, to rise in pure spirituality and be identified with God whose image it is. And it is meant to spiritualise the body, and carry it in that same upward direction – as far as that is possible on earth – aiming at least toward some position between earth and heaven. If heaven is unattainable before death, at least one can strive to be lifted up from the earth. But fallen man, with such as Ovid for his guide, is only too prone to cleave downward, to the flesh, to the earth, and to corruption. And this is the opposition that William traces in the first chapter of his Nature and Dignity of Love, the work which was called Anti-Masonem in the middle ages, on account of its avowed attack on the Ars Amatoria.
