On the Tilling of the Earth by Noah (66-70)

Therefore since the mind, the ruler of the flock, having taken the flock of the soul, using the law of nature as its teacher, governs it consistently and vigorously, rendering it worthy of approbation and great praise; but when it manages it sluggishly and indulgently, with a disregard of law, then it renders it blameable. Very naturally, therefore, the one will assume the name of a king, being addressed as a shepherd, but the other will only have the title of a confectioner, or of a baker, being called a keeper of sheep, supplying the means of feasting and gluttonous eating to cattle accustomed to gorge themselves to satiety.

I have now therefore explained, in no superficial manner, in what way a husbandman differs from a tiller of the ground, and a shepherd from a keeper of sheep. There is also a third point, having some connection with what has already been said, which we will now proceed to speak of. For I consider

and he has given himself up to an irrational and restive animal, to such a degree that it is absolutely inevitable that he must be carried wherever the animal chooses to go, and if he fails to see beforehand a chasm in the earth, or a deep pit, it has happened before now that such a man, in consequence of the impetuosity of his course, has been thrown headlong down a precipice and dashed to pieces.

But a horseman, on the other hand, when he is about to mount, takes the bridle in his hand, and then taking hold of the mane on the horse’s neck, he leaps on; and though he appears to be carried by the horse, yet, if one must tell the truth, he in reality guides the animal that carries him, as a pilot guides a ship. For the pilot too, appearing to be carried by the ship which he is managing, does in real truth guide it, and conducts it to whatever harbour he is himself desirous to hasten.

While, therefore, the horse goes on in obedience to the rein, the horseman pats the horse, as if praising it; but when it goes on with too great impetuosity, and is carried away beyond moderation, then he pulls it back with force and vigour, so as to restrain its speed. But if the horse continue to be disobedient, then he takes the whole bridle, and pulls him back, and drags back his neck, so that he is compelled to stop.
