“Politics is the art of preventing people from taking part in affairs which properly concern them.”

The Art of Persuasion
Context: This art, which I call the art of persuading, and which, properly speaking, is simply the process of perfect methodical proofs, consists of three essential parts: of defining the terms of which we should avail ourselves by clear definitions, of proposing principles of evident axioms to prove the thing in question; and of always mentally substituting in the demonstrations the definition in the place of the thing defined.

Variant: If we can prevent the government from wasting the labors of the people, under the pretense of taking care of them, they must become happy.

Section 3 : Work Democracy versus Politics. The Natural Social Forces for the Mastery of the Emotional Plague;
Variant translation: Under the influence of politicos, the masses blame the powers that be for wars. In the first world war it was the munition magnates, in the second the Psychopath General. This is shifting the responsibility. The blame for the war belongs only and alone to the same masses of people who have all the means of preventing wars. The same masses of people who — partly through indolent passivity, partly through their active behavior — make possible the catastrophes from which they themselves suffer most horribly. To emphasize this fault of the masses, to give them the full responsibility, means taking them seriously. On the other hand, to pity the masses as a poor victim means treating them like a helpless child. The first is the attitude of the genuine fighter for freedom, the latter is the attitude of the politico.
The Mass Psychology of Fascism (1933), Ch. 10 : Work Democracy
Context: Under the influence of politicians, masses of people tend to ascribe the responsibility for wars to those who wield power at any given time. In World War I it was the munitions industrialists; in World War II it was the psychopathic generals who were said to be guilty. This is passing the buck. The responsibility for war falls solely upon the shoulders of these same masses of people, for they have all the necessary means to avert war in their own hands. In part by their apathy, in part by their passivity, and in part actively, these masses of people make possible the catastrophes under which they themselves suffer more than anybody else. To stress this guilt on the part of masses of people, to hold them solely responsible, means to take them seriously. On the other hand, to commiserate masses of people as victims, means to treat them as small, helpless children. The former is the attitude held by genuine freedom-fighters; the latter the attitude held by the power-thirsty politicians.
