Book 1
2.18
It is above all things necessary that our future orator, who will have to live in the utmost publicity and in the broad daylight of public life, should become accustomed from his childhood to move in society without fear and habituated to a life far removed from that of the pale student, the solitary and recluse. His mind requires constant stimulus and excitement, whereas retirement such as has just been mentioned induces languor and the mind becomes mildewed like things that are left in the dark, or else flies to the opposite extreme and becomes puffed up with empty conceit; for he who has no standard of comparison by which to judge his own powers will necessarily rate them too high.
2.19
Again when the fruits of his study have to be displayed to the public gaze, our recluse is blinded by the sun's glare, and finds everything new and unfamiliar, for though he has learnt what is required to be done in public, his learning is but the theory of a hermit.
2.20
I say nothing of friendships which endure unbroken to old age having acquired the binding force of a sacred duty: for initiation in the same studies has all the sanctity of initiation in the same mysteries of religion. And where shall he acquire that instinct which we call common feeling, if he secludes himself from that intercourse which is natural not merely to mankind but even to dumb animals?
