It is as easy to speak extempore as to be silent. A man sitting silent admires the miracle of free, impassioned, picturesque speech in the man addressing the assembly, a state of being & of power how unlike his own. Presently his own emotion rises to his lips & overflows in speech. He must also rise & say somewhat. Once embarked, once having overcome the novelty of the situation he finds it just as easy & natural to speak, to speak with thoughts, with pictures, with rhythmical balance of sentences—as it was to sit silent for it needs not to do but to suffer; he only adjusts himself to the free spirit which gladly utters itself through him. This is a practical lesson in the doctrine that there is but one Mind. Motion is as easy as rest.
