While superfluity engenders disgust, appetite is but whetted when fruit is forbidden.
Come la copia delle cose genera fastidio, cosl l'esser le desiderate negate moltiplica l'appetito.

As a plethora of good things generates satiety, so does the denial of our wants increase our appetite. (tr. Harbottle and Dalbiac)
