“To be frank, politics is about wanting power, getting it, exercising it, and keeping it.”

Context: We must distinguish between military and political power.
Political power is a psychological relation between those who exercise it and those over whom it is exercised. It gives the former control over certain actions of the latter through the influence which the former exert over the latter's minds. That influence may be exerted through orders, threats, persuasion, or a combination of any of these.

Mittel Energie auszuüben und nur ihn anzuordnen der Energie besitzt kann sie ausüben. Dieser direkte Anschluß der Energie und der Richtlinie bildet die grundlegende Wahrheit aller Politik und den Schlüssel zu aller Geschichte.

Context: The incapacity for freedom can only arise from a want of moral and intellectual power; to elevate this power is the only way to counteract this want; but to do this presupposes the exercise of that power, and this exercise presupposes the freedom which awakens spontaneous activity. Only it is clear we cannot call it giving freedom, when fetters are unloosed which are not felt as such by him who wears them. But of no man on earth—however neglected by nature, and however degraded by circumstances—is this true of all the bonds which oppress and enthral him. Let us undo them one by one, as the feeling of freedom awakens in men’s hearts, and we shall hasten progress at every step. There may still be great difficulties in being able to recognize the symptoms of this awakening. But these do not lie in the theory so much as in its execution, which, it is evident, never admits of special rules, but in this case, as in every other, is the work of genius alone.

Je crois que le pouvoir politique s’exerce encore, s’exerce en outre, de plus, par l’intermédiaire d’un certain nombre d’institutions qui ont l’air comme ça de n’avoir rien de commun avec le pouvoir politique, qui ont l’air d’en être indépendantes et qui ne le sont pas.
