De Agricultura

and what can man be but the kind that is in every one of us, which is accustomed to reap the advantage from all that is sown or planted? But since milk is the food of infants, but cakes made of wheat are the food of fullgrown men, so also the soul must have a milk-like nourishment in its age of childhood, namely, the elementary instruction of encyclical science. But the perfect food which is fit for men consists of explanations dictated by prudence, and temperance, and every virtue. For these things being sown and implanted in the mind will bring forth most advantageous fruit, namely, good and praiseworthy actions.
