From Les Miserables, Volume 4, Book 1, Chapter 4. (There’s much good and timely stuff in the long, expository parts that everyone skips in order to get back to the plot.)
There are, in revolutions, swimmers who go against the current; they are the old parties.
For the old parties who clung to heredity by the grace of God, think that revolutions, having sprung from the right to revolt, one has the right to revolt against them. Error. For in these revolutions, the one who revolts is not the people; it is the king. Revolution is precisely the contrary of revolt. Every revolution, being a normal outcome, contains within itself its legitimacy, which false revolutionists sometimes dishonor, but which remains even when soiled, which survives even when stained with blood.
Revolutions spring not from an accident, but from necessity. A revolution is a return from the fictitious to the real. It is because it must be that it is.
