Context: Why, then, are the world's governments intent on controlling and regulating the Internet? Free speech is most threatening to authoritarian systems such as autocracies, militaries, the police and security services. Security services in principle exist for our protection but that is so only when they are accountable to the public for their considerable power. We are seeing a push by these agencies to move beyond the rule of law, to be accountable to no one but themselves. National security is becoming the new word of God to which all must submit in blind obedience. The decisions made, the liberties eroded, the crimes committed in the name of national security cannot be challenged because the information on which they are based remains secret.

"Publisher's Statement", in the first issue of National Review (19 November 1955).
Context: Radical conservatives in this country have an interesting time of it, for when they are not being suppressed or mutilated by Liberals, they are being ignored or humiliated by a great many of those of the well-fed Right, whose ignorance and amorality have never been exaggerated for the same reason that one cannot exaggerate infinity.
There are, thank Heaven, the exceptions. There are those of generous impulse and a sincere desire to encourage a responsible dissent from the Liberal orthodoxy. And there are those who recognize that when all is said and done, the market place depends for a license to operate freely on the men who issue licenses — on the politicians. They recognize, therefore, that efficient getting and spending is itself impossible except in an atmosphere that encourages efficient getting and spending. And back of all political institutions there are moral and philosophical concepts, implicit or defined. Our political economy and our high-energy industry run on large, general principles, on ideas — not by day-to-day guess work, expedients and improvisations. Ideas have to go into exchange to become or remain operative; and the medium of such exchange is the printed word.
