A quote
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.
