John Dos Passos said this quote

Then all at once he´d hear his own voice enunciating clearly and firmly, feel its reverberance along the walls and ceiling, feel ears growing tense, men and women leaning forward in their chairs, see the rows of faces quite clearly, the groups of people who couldn´t find seats crowding at the doors. Phrases like `protest, massaction, united working-class of this country and the world, revolution´, would light up the eyes and faces under him like the glare of a bonfire.
