text: How mad is he who leaves the lecture-room in a happy frame of mind simply because of applause from the ignorant! Why do you take pleasure in being praised by men whom you yourself cannot praise? Fabianus used to give popular talks, but his audience listened with self-control. Occasionally a loud shout of praise would burst forth, but it was prompted by the greatness of his subject, and not by the sound of oratory that slipped forth pleasantly and softly. There should be a difference between the applause of the theatre and the applause of the school; and there is a certain decency even in bestowing praise. If you mark them carefully, all acts are always significant, and you can gauge character by even the most trifling signs. The lecherous man is revealed by his gait, by a movement of the hand, sometimes by a single answer, by his touching his head with a finger, by the shifting of his eye. The scamp is shown up by his laugh; the madman by his face and general appearance. These qualities become known by certain marks; but you can tell the character of every man when you see how he gives and receives praise. The philosopher's audience, from this corner and that, stretch forth admiring hands, and sometimes the adoring crowd almost hang over the lecturer's head. But, if you really understand, that is not praise; it is merely applause. These outcries should be left for the arts which aim to please the crowd; let philosophy be worshipped in silence. Young men, indeed, must sometimes have free play to follow their impulses, but it should only be at times when they act from impulse, and when they cannot force themselves to be silent. Such praise as that gives a certain kind of encouragement to the hearers themselves, and acts as a spur to the youthful mind. But let them be roused to the matter, and not to the style; otherwise, eloquence does them harm, making them enamoured of itself, and not of the subject.
