“To understand the nature of the Revolution we must call it "progress"; and we may define progress by the word "tomorrow".”

“If you wish to understand what Revolution is, call it Progress; and if you wish to understand what Progress is, call it Tomorrow.”

“Yes, the brutalities of progress are called revolutions”

“In saying no to progress, it is not the future which they condemn, but themselves. They give themselves a melancholy disease; they inoculate themselves with the past. There is but one way of refusing tomorrow, that is to die.”

“Progress is the goal, the ideal is the type. What is this ideal? It is God. Ideal, absolute, perfection, infinity: identical words.”

“Let no one misunderstand our idea; we do not confound what are called 'political opinions' with that grand aspiration after progress with that sublime patriotic, democratic, and human faith, which, in our days, should be the very foundation of all generous intelligence.”

“Progress is not accomplished in one stage.”
