In 1917, the Russian peasants were demanding: “Land and Freedom!” But Lenin and Stalin is what they got.

In 1933, the Germans were demanding: “Room to live!” But what they got was Hitler.

In 1793, the French were shouting: “Liberty, Equality, Fraternity!” What they got was Napoleon.

In 1776, the Americans were proclaiming “The Rights of Man”—and, led by political philosophers, they achieved it.

No revolution, no matter how justified, and no movement, no matter how popular, has ever succeeded without a political philosophy to guide it, to set its direction and goal.
