Institutio Oratoria

This view is universally accepted, although in my opinion rhetoric draws largely on the two other kinds of art. For it may on occasion be content with the mere examination of a thing. Rhetoric is still in the orator's possession even though he be silent, while if he gives up pleading either designedly or owing to circumstances over which he has no control, he does not therefore cease to be an orator, any more than a doctor ceases to be a doctor when he withdraws from practice.

Perhaps the highest of all pleasures is that which we derive from private study, and the only circumstances under which the delights of literature are unalloyed are when it withdraws from action, that is to say from toil, and can enjoy the pleasure of self-contemplation.
