The discourse which I gave on the subject of listening to lectures I have written out and sent to you, my dear Nicander, so that you may know how rightly to listen to the voice of persuasion, now that you are no longer subject to authority, having assumed the garb of a man. Now absence of control, which some of the young men, for want of education, think to be freedom, establishes the sway of a set of masters, harsher than the teachers and attendants of childhood, in the form of the desires, which are now, as it were, unchained. And just as Herodotus says that women put off their modesty along with their undergarments, so some of our young men, as soon as they lay aside the garb of childhood, lay aside also their sense of modesty and fear, and, undoing the habit that invests them, straightway become full of unruliness. But you have often heard that to follow God and to obey reason are the same thing, and so I ask you to believe that in persons of good sense the passing from childhood to manhood is not a casting off of control, but a recasting of the controlling agent, since instead of some hired person or slave purchased with money they now take as the divine guide of their life reason, whose followers alone may deservedly be considered free. For they alone, having learned to wish for what they ought, live as they wish; but in untrained and irrational impulses and actions there is something ignoble, and changing one's mind many times involves but little freedom of will.

We may find a comparison in the case of newly naturalized citizens; those among them who were alien born and perfect strangers find fault with many of the things that are done, and are discontented; whereas those who come from the class of resident aliens, having been brought up under our laws and grown to be well acquainted with them, have no difficulty in accepting what devolves upon them and are content. And so you, who have been brought up for a long time in contact with philosophy, and have from the beginning been accustomed to philosophic reasoning as an ingredient in every portion of early instruction and information, ought to feel like an old friend and familiar when you come to philosophy, which alone can array young men in the manly and truly perfect adornment that comes from reason.

I think you may not find unwelcome some preliminary remarks about the sense of hearing, which Theophrastus asserts is the most emotional of all the senses. For nothing which can be seen or tasted or touched brings on such distractions, confusions, and excitements, as take possession of the soul when certain crashing, clashing, and roaring noises assail the hearing. Yet this sense is more rational than emotional. For while many places and parts of the body make way for vice to enter through them and fasten itself upon the soul, virtue's only hold upon the young is afforded by the ears, if they be uncontaminated and kept from the outset unspoiled by flattery and untouched by vile words. For this reason Xenocrates advised putting ear-protectors on children rather than on athletes, on the ground that the latter have only their ears disfigured by the blows they receive, while the former have their characters disfigured by the words they hear; not that he would thus court heedlessness or deafness, but he advises vigilance against vile words, until such time as other words, of good sort, fostered in the character by philosophy, should, like watchmen, have taken under their charge the post chiefly exposed to influence and persuasion. And Bias of old, on receiving orders to send to Amasis the portion of the sacrificial animal which was at the same time the best and the worst, cut out the tongue and sent it to him, on the ground that speech contains both injuries and benefits in the largest measure. Most people in bestowing an affectionate kiss on little children not only take hold of the children by the ears but bid the children to do the same by them, thus insinuating in a playful way that they must love most those who confer benefit through the ears. For surely the fact is plain, that the young man who is debarred from hearing all instruction and gets no taste of speech not only remains wholly unfruitful and makes no growth towards virtue, but may also be perverted towards vice, and the product of his mind, like that of a fallow and untilled piece of ground, will be a plentiful crop of wild oats. For if the impulses towards pleasure and the feelings of suspicion towards hard work (which are not of external origin nor imported products of the spoken word, but indigenous sources, as it were, of pestilent emotions and disorders without number) be allowed to continue unconstrained along their natural channels, and if they be not either removed or diverted another way through the agency of goodly discourse, thus putting the natural endowments in a fit condition, there is not one of the wild beasts but would be found more civilized than man.

Therefore, since listening to lectures is attended by great benefit, but by no less danger, to the young, I think it is a good thing to discuss the matter continually both with oneself and with another person. The reason for so doing is because we observe that a poor use is made of this by the great majority of persons, who practise speaking before they have acquired the habit of listening. They think that there must be study and practice in discourse, but as for hearing, benefit will come however it be used. It is true that, in the case of persons playing ball, learning to throw and learning to catch take place at the same time; but in the use of discourse its proper reception comes before its delivery, just as conception and pregnancy come before parturition. It is said that when fowls labour and bring forth wind-eggs, these result from some imperfect and infertile residue from conception; and if young men have not the power to listen, or the habit of getting some profit through listening, the speech brought forth by them is windy indeed, and

Void of repute and unheeded beneath the clouds it is scattered.

For although they can incline and turn vessels properly to receive any liquid which is being poured into them, in order that there may actually be a filling and not a spilling, they never learn to apply themselves to a speaker and to accord attention to his lecture so that none of its good points may escape them. But here is the most ridiculous thing in the world: if they chance upon somebody who is giving an account of a dinner or a procession or a dream or a wordy brawl which he has had with another man, they listen in silence, and importune him to continue; yet if anybody draws them to one side and tries to impart something useful, or to advise them of some duty, or to admonish them when in the wrong, or to mollify them when incensed, they have no patience with him; but, eager to get the better of him if they can, they fight against what he says, or else they beat a hasty retreat in search of other foolish talk, filling their ears like worthless and rotten vessels with anything rather than the things they need. As skilful horse-trainers give us horses with a good mouth for the bit, so too skilful educators give us children with a good ear for speech, by teaching them to hear much and speak little. Indeed, Spintharus declared in commendation of Epameinondas that it was not easy to find a man who knew more and spoke less. And it is a common saying that nature has given to each of us two ears and one tongue, because we ought to do less talking than listening.

In all cases, then, silence is a safe adornment for the young man, and especially so, when in listening to another he does not get excited or bawl out every minute, but even if the remarks be none too agreeable, puts up with them, and waits for the speaker to pause, and, when the pause comes, does not at once interpose his objection, but, as Aeschines puts it, allows an interval to elapse, in case the speaker may desire to add something to what he has said, or to alter or unsay anything. But those who instantly interrupt with contradictions, neither hearing nor being heard, but talking while others talk, behave in an unseemly manner; whereas the man who has the habit of listening with restraint and respect, takes in and masters a useful discourse, and more readily sees through and detects a useless or false one, showing himself thus to be a lover of truth and not a lover of disputation, nor froward and contentious. Wherefore it is sometimes said not unaptly that it is even more necessary to take the wind of self-opinion and conceit out of the young, than to deflate wine-skins, if you wish to fill them with something useful; otherwise, being full of bombast and inflation, they have no room to receive it.

Moreover, just as in learning to read and write, or in taking up music or physical training, the first lessons are attended with much confusion, hard work, and uncertainty, but later, as the learner makes progress, by slow degrees, just as in his relations with human beings, a full familiarity is engendered and knowledge which renders everything attractive, feasible, and easy, both to say and to do, so also is it with philosophy, which undoubtedly has something knotty and unfamiliar in its terms and subject matter at the outset; yet one ought not to take fright at its beginnings, and to abandon it in timorous and craven fashion; rather should he examine each point, and persist and stick to the task of getting on, while awaiting that familiarity which makes every noble thing a pleasure. For come it will without long delay, bringing with it abundant light for the subject of study; it will inspire also a passionate love for virtue; and anyone who could endure to pass the rest of his life without this passion, because he has exiled himself from philosophy for want of true manliness, brands himself either as a very presumptuous man or else a coward.

It is quite possible that the subject of philosophy contains some matter which is difficult for young and inexperienced students to apprehend at the outset. But, at the same time, they must hold themselves responsible for most of the uncertainty and misunderstanding in which they find themselves involved, since quite opposite characters come to fall into the same error. Some, because of a feeling of shame and a desire to spare the speaker, hesitate to ask questions and to get the argument firmly fixed in their minds, nodding their heads in assent as though they comprehended it; others, led by an unseasonable ambition and inane rivalry with their fellow-students, to show off their acuteness and their ability to learn easily, avow that they have the meaning before they have grasped it, and so do not grasp it at all. Then the result is that those modest and silent persons, after leaving the lecture, distress themselves over their difficulties, and finally, driven by necessity, with even greater shame this time, they trouble the lecturers with questions which they should have asked before, and try to catch up; but with the ambitious and self-confident young men, the result is that they are all the time trying to cover up and conceal the ignorance that abides with them.

Let us therefore put from us all such foolishness and pretension, and, as we go onward to the task of learning, let us take pains thoroughly to comprehend all profitable discourses; let us submit with patience to the laughter of those reputed to be clever, as did Cleanthes and Xenocrates, who, although they seemed to be slower than their schoolmates, yet did not try to escape learning or give it up in despair, but were the first to make jokes at themselves by comparing themselves to narrow-necked bottles and bronze tablets, as much as to say that they found great difficulty in taking in what was said, yet they kept it safely and securely. For not only is one bound, as Phocylides says,

Many a time to be cheated of hope when he seeks to be noble,

but he is bound also many a time to be laughed at and to be in disrepute, and to put up with joking and buffoonery as he struggles with might and main against his ignorance and overthrows it.

On the other hand, however, we certainly must not neglect the mistake that leads to the opposite extreme, which some persons are led to commit by laziness, thus making themselves unpleasant and irksome. For when they are by themselves they are not willing to give themselves any trouble, but they give trouble to the speaker by repeatedly asking questions about the same things, like unfledged nestlings always agape toward the mouth of another, and desirous of receiving everything ready prepared and predigested. There is another class, who, eager to be thought astute and attentive out of due place, wear out the speakers with loquacity and officiousness, by continually propounding some extraneous and unessential difficulty and asking for demonstrations of matters that need no demonstration, and so, as Sophocles puts it,

Much time it takes to go a little way,

not only for themselves but for the rest of the company too. For holding back the speaker on every possible occasion by their inane and superfluous questions, as in a company of persons travelling together, they impede the regular course of the lecture, which has to put up with halts and delays. Now such persons are, according to Hieronymus, like cowardly and persistent puppies which, at home, bite at the skins of wild animals, and tear off what bits they can, but never touch the animals themselves. But as for those lazy persons whom we have mentioned, let us urge them that, when their intelligence has comprehended the main points, they put the rest together by their own efforts, and use their memory as a guide in thinking for themselves, and, taking the discourse of another as a germ and seed, develop and expand it. For the mind does not require filling like a bottle, but rather, like wood, it only requires kindling to create in it an impulse to think independently and an ardent desire for the truth. Imagine, then, that a man should need to get fire from a neighbour, and, upon finding a big bright fire there, should stay there continually warming himself; just so it is if a man comes to another to share the benefit of a discourse, and does not think it necessary to kindle from it some illumination for himself and some thinking of his own, but, delighting in the discourse, sits enchanted; he gets, as it were, a bright and ruddy glow in the form of opinion imparted to him by what is said, but the mouldiness and darkness of his inner mind he has not dissipated nor banished by the warm glow of philosophy.

Finally, if there be need of any other instruction in regard to listening to a lecture, it is that it is necessary to keep in mind what has here been said, and to cultivate independent thinking along with our learning, so that we may acquire a habit of mind that is not sophistic or bent on acquiring mere information, but one that is deeply ingrained and philosophic, as we may do if we believe that right listening is the beginning of right living.
