George Orwell - 1984

I tell you Winston, that reality is not external. Reality exists in the human mind, and nowhere else. Not in the individual mind, which can make mistakes, and in any case soon perishes: only in the mind of the party, which is collective and immortal. Whatever the party holds to be truth, is truth. It is impossible to see reality except by looking through the eyes of the Party.

(...)

The Party seeks power entirely for its own sake. We are not interested in the good of others; we are interested solely in power. Not wealth or luxury or long life or happiness: only power, pure power. What pure power means you will understand presently. We are different from all the oligarchies of the past, in that we know what we are doing. All the others, even those who resembled ourselves, were cowards and hypocrites.

Alfred Jules Ayer - Language, Truth, and Logic

The metaphysician, on the other hand, does not intend to write nonsense. He lapses into it through being deceived by grammar, or through committing errors of reasoning, such as that which leads to the view that the sensible world is unreal. But it is not the mark of a poet simply tdmake mistakes of this sort. There are some, indeed, who would see in the fact that the metaphysician's utterances are senseless a reason against the view that they have aesthetic value.

Murray N. Rothbard - The Ethics of Liberty

All other persons and groups in society (except for acknowledged and sporadic criminals such as thieves and bank robbers) obtain their income voluntarily: either by selling goods and services to the consuming public, or by voluntary gift (e.g., membership in a club or association, bequest, or inheritance). Only the State obtains its revenue by coercion, by threatening dire penalties should the income not be forthcoming. That coercion is known as "taxation," although in less regularized epochs it was often known as “tribute." Taxation is theft, purely and simply even though it is theft on a grand and colossal scale which no acknowledged criminals could hope to match. It is a compulsory seizure of the property of the State's inhabitants, or subjects.

Murray N. Rothbard - For A New Liberty

... libertarians and other Americans must guard against a priori history: in this case, against the assumption that, in any conflict, the State which is more democratic or allows more internal freedom is necessarily or even presumptively the victim of aggression by the more dictatorial or totalitarian State. There is simply no historical evidence whatever for such a presumption. In deciding on relative rights and wrongs, on relative degrees of aggression in any dispute in foreign affairs, there is no substitute for a detailed empirical, historical investigation of the dispute itself. It should occasion no great surprise, then, if such an investiga tion concludes that a democratic and relatively far freer United States has been more aggressive and imperialistic in foreign affairs than a relatively totalitarian Russia or China.

Colorless green ideas sleep furiously.

Frédéric Bastiat - The Law

It seems to me that this is theoretically right, for whatever the question under discussion– whether religious, philosophical, political, or economic; whether it concerns prosperity, morality, equality, right, justice, progress, responsibility, cooperation, property, labor, trade, capital, wages, taxes, population, finance, or government– at whatever point on the scientific horizon I begin my researches, I invariably reach this one conclusion: The solution to the problems of human relationships is to be found in liberty.
