Good can imagine Evil; but Evil cannot imagine Good.
My deepest feeling about politicians is that they are dangerous lunatics to be avoided when possible and carefully humored; people, above all, to whom one must never tell the truth.
The belief that politics can be scientific must inevitably produce tyrannies. Politics cannot be a science, because in politics theory and practice cannot be separated, and the sciences depend upon their separation. Empirical politics must be kept in bounds by democratic institutions, which leave it up to the subjects of the experiment to say whether it shall be tried, and to stop it if they dislike it, because, in politics, there is a distinction, unknown to science, between Truth and Justice.
