'I am she who have fashioned the form and eminence of man into the likeness of the original mundane mechanism, that in him, as in a mirror of the world itself, combined nature may appear. For just as, of the four elements, the concordant discord, the single plurality, the dissonant consonance, the dissenting agreement, produce the structures of the palace of earth, so, of four ingredients, the similar unsimilarity, the unequal equality, the unformed conformity, the separate identity, firmly erect the building of the human body. And those qualities which come together as mediators among the elements -these establish a firm peace among the four humors.
And just as the army of the planets opposes with contrary motion the fixed rolling of the firmament, so in man is found a continual hostility between lust and reason. For the activity of reason, taking its rise from a celestial source, passes through the low levels of earth, and, watchful of heavenly things, turns again to heaven. The activities of lust, on the other hand, wandering waywardly and contrary to the firmament of reason, turn and slip down into the decline of things of earth. Now the latter, lust, leads the human mind into the ruin of vices, so that it perishes ; the former, reason, bids it, as it rises, to ascend to the serenity of virtue. The one dishonors man, and changes him to a beast; the other mightily transfigures him into a god. Reason illuminates the darkness of the brain by the light of contemplation; lust extinguishes the radiance of the mind by the night of desire. Reason makes man to talk with angels; lust forces him to wanton with brutes. Reason teaches man to find in exile a home; lust forces him in his home to be an exile.
