just as the more fertile a field is, the richer the crop of thorns and of thistles that it can produce, so an excellent intelligence becomes filled with fanciful notions, if it be not sown with the seeds of wisdom and of virtue; and, just as a mill-stone grinds itself away with noise and grating, and often cracks and breaks, if wheat, the raw material of flour, be not supplied to it, so an active mind, if void of serious things, entangles itself utterly with vain, curious, and noxious thoughts, and becomes the cause of its own destruction.
8. What are the rich without wisdom but pigs stuffed with bran? What are the poor who have no understanding of affairs but asses laden with burdens? What is a handsome though ignorant man but a parrot adorned with feathers, or, as has been said, a golden sheath in which there is a leaden dagger?
9. For those who are in any position of authority, for kings, princes, magistrates, pastors of churches, and doctors, it is as necessary to be imbued with wisdom as it is for a guide to have eyes, an interpreter to have speech, a trumpet to be filled with sound, or a sword to have an edge. Similarly, those in subordinate positions should be educated that they may know how to obey their superiors wisely and prudently, not under compulsion, with the obedience of an ass, but of their own free will and from love of order. For a rational creature should be led, not by shouts, imprisonment, and blows, but by reason. Any other method is an insult to God, in whose image all men are made, and fills human affairs with violence and unrest.
10. We see then that all who are born to man’s estate have need of instruction, since it is necessary that, being men, they should not be wild beasts, savage brutes, or inert logs. It follows also that one man excels another in exact proportion as he has received more instruction. We may conclude this chapter with the words of the “Wise Man.” “He who deems wisdom and discipline of no avail is wretched; his hopes (of attaining his desire) are vain, his labour is fruitless, and his work idle” (Wisdom iii. 11).
