Therefore all such sheepishness and self-conceit being set aside, let us learn to lay up in our minds whatever is usefully said, enduring to be laughed at by such as set up for wits and railers. This course took Cleanthes and Xenocrates, who being somewhat slower than their fellows did not therefore give over hearing or despond; but prevented the jests of others, by comparing themselves to narrow-mouthed vessels and to copper plate; because, though they received learning with some difficulty, yet they retained it surely. For he that will be a good man must not only, as Phocylides says, — Expect much fraud, and many a time be caught, — but be laughed at and disgraced, and endure many scurrilous and virulent reflections; he must also encounter ignorance and wrestle with it with all the strength of his mind, and subdue it too. Neither on the other hand must the faults be passed by which some troublesome people commit out of mere laziness and negligence; such men as will not bestow any pains in considering themselves, but asking often the same questions are a perpetual vexation to the speaker; like callow birds always gaping at the bill of the old one, and still reaching after what has been prepared and worked over by others. Another sort there are, who, affecting the reputation of quickness and attention, confound the speaker with their pragmatical curiosity and jargon, always haling in something unnecessary and requiring demonstrations of things foreign to the business in hand. Thus a short way is long and tedious made, as Sophocles says, and that not only to themselves, but others also. For by taking off the speaker with vain and unnecessary questions they retard the progress of instruction, like travellers in the road, by impertinent halts and stops. Hieronymus compares these men to lazy and greedy curs, which within doors bite and tear the skins of wild animals and lie tugging at their shaggy hair, but in the field dare not fasten upon beasts themselves. A Concluding Exhortation. Yet one exhortation let me leave with these people, that having received the general heads of things they would supply the rest by their own industry, making their memory a guide to their invention; and that, looking on the discourse of others only as a kind of first principle or seed, they would take care to cherish and increase it. For the mind requires not like an earthen vessel to be filled up; convenient fuel and aliment only will inflame it with a desire of knowledge and ardent love of truth. Now, as it would be with a man who, going to his neighbor’s to borrow fire and finding there a great and bright fire, should sit down to warm himself and forget to go home; so is it with the one who comes to another to learn, if he does not think himself obliged to kindle his own fire within and inflame his own mind, but continues sitting by his master as if he were enchanted, delighted by hearing. Such a one, although he may get the name of a philosopher, as we get a bright color by sitting by the fire, will never clear away the mould and rust of his mind, and dispel the darkness of his understanding by the help of philosophy. In fine, if there is any other precept concerning hearing, it is briefly this, to be careful in observing the last exhortation, — that is, to join the exercise of our invention to our hearing; that so, while we lay down the rule that hearing well is the first step to living well, we may not content ourselves with a superficial commonplace knowledge, but endeavor after such a philosophical habit as shall be deeply imprinted on the mind.
