Liberty is the ideal of aristocracy, just as equality stands for the bourgeoisie and fraternity for the peasantry. One can combine liberty with fraternity but neither of them with equality.

It must be stated again in all candor that equality presupposes force on account of its unnaturalness. Force is the end of liberty as well as of fraternity. In order to level a landscape full of mountains and valleys one needs dynamite, tractors, picks, and shovels. By filling the valleys with the mountaintops a level with a uniform altitude could be established. Thus there is only liberty or equality.
