This leads up to the matter of proposing problems. Now the person who comes to a dinner is bound to eat what is set before him and not to ask for anything else or to be critical; so he who comes to a feast of reason, if it be on a specified subject, must feel bound to listen to the speaker in silence. For those persons who lead the speaker to digress to other topics, and interject questions, and raise new difficulties, are not pleasant or agreeable company at a lecture; they get no benefit from it, and they confuse both the speaker and his speech. However, when the speaker requests his hearers to ask questions or to propose problems, one should always manifestly propose some problem which is useful and essential. Now Odysseus among the suitors is derided for Asking for morsels of food and not for swords or for cauldrons,Homer, , xvii. 222. for they regard it just as much a sign of magnanimity to ask for something great as to give it. But there is more reason for ridiculing a hearer who diverts the speaker to petty and frivolous problems, such as some of the young men are in the habit of proposing when they are only fooling and withal showing off their skill in logic or mathematics; take, for example, the question about the division of indeterminate propositions Apparently a quibble in logic: Man lives and breathes; which man lives and which man breathes? or What is movement as determined by the bounding side or by the diagonal ? When a body moves are its various positions determined by the position of its diagonal (i.e. interior lines) or of its exterior lines? To such by the position of its diagonal (i.e. interior lines) or of its exterior lines ? persons we may retort with the remark of Philotimus Again referred to by Plutarch, , 73 B. to the man who was dying of consumption. When he had addressed the physician, asking him for something to cure a sore finger, Philotimus, perceiving his condition from his colour and respiration, said,My dear sir, your concern is not about a sore finger. And so for you, young man, it is not the time to be inquiring about such questions, but how you may be rid of self-opinion and pretension, love affairs and nonsense, and settle down to a modest and wholesome mode of living.
