“Progress is not accomplished in one stage.”

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

“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.”

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

“Have courage for the great sorrows of life and patience for the small ones; and when you have laboriously accomplished your daily task, go to sleep in peace. God is awake.”

“Yes, the brutalities of progress are called revolutions”

“Daring is the price of progress. All splendid conquests are the prize of boldness, more or less.”
