Cynics treat values as equivalent and instrumental. Statesmen base practical decisions on moral convictions. It is always easy to divide the world into idealists and power-oriented people. The idealists are presumed to be the noble people, and the power-oriented people are the ones that cause all the world’s trouble. But I believe more suffering has been caused by prophets than by statesmen.
There is no realism without an element of idealism. The idea of abstract power only exists for academics, not in real life.
