_Son._ Since you seem to think that sufficient has been said about weapons both for attack and defense, how they should be made or built, and on what occasion each kind should be used (and after your comments these things are very clear to me), I now wish to ask whether there may not be other subjects which you think ought to be discussed, such as pertain to customs that one must observe in the presence of great men or at royal courts. _Father._ There still remain a number of things which a man should not fail to hear discussed and to reflect upon, if he is to attend on kings or other magnates and wishes to be ranked among them as a worthy man. But there are three things (which are, however, almost the same in reality) which one must observe with care: they are wisdom, good breeding, and courtesy. It is courtesy to be friendly, humble, ready to serve, and elegant in speech; to know how to behave properly while conversing or making merry with other men; to know precisely, when a man is conversing with women, whether they be young or older in years, of gentle or humble estate, how to select such expressions as are suited to their rank and are as proper for them to hear as for him to use. In like manner when one speaks with men, whether they be young or old, gentle or humble, it is well to know how to employ fitting words and how to determine what expressions are proper for each one to take note of. Even when mere pleasantry is intended, it is well to choose fair and decent words. It is also courtesy to know how to discriminate in language, when to use plural and when to use singular forms in addressing the men with whom one is conversing; to know how to select one’s clothes both as to color and other considerations; and to know when to stand or sit, when to rise or kneel. It is also courtesy to know when a man ought to let his hands drop gently and to keep them quiet, or when he ought to move them about in service for himself or for others; to know in what direction to turn his face and breast, and how to turn his back and shoulders. It is courtesy to know precisely when he is free to wear his cloak, hat, or coif, if he has one, and when these are not to be worn; also to know, when at the table, whether good breeding demands that one must watch the great men partake of food, or whether one may eat and drink freely in any way that seems convenient and proper. It is also courtesy to refrain from sneers and contemptuous jests, to know clearly what churlishness is and to avoid it carefully.
