Concurring, Whitney v. California, 274 U.S. 357, 375 (1927), at 375. In this case, in which the Court upheld a California anti-Communist statute, Brandeis, writing in a concurrence joined by Justice Oliver Wendell Holmes, Jr., concurred in the judgment but not in the reasoning. Whitney was later overruled (with the later Court adopting Brandeis's reasoning) in Brandenburg v. Ohio, 395 U.S. 444 (1969).

The Tale of Taleisin
Context: I have fled in the shape of a raven of prophetic speech,
in the shape of a satirizing fox,
in the shape of a sure swift,
in the shape of a squirrel vainly hiding.
I have fled in the shape of a red deer,
in the shape of iron in a fierce fire,
in the shape of a sword sowing death and disaster,
in the shape of a bull, relentlessly struggling.

"What I Believe" in The Forum 84 (September 1930), p. 139; some of these expressions were also used separately in other Mencken essays.
1930s
Context: I believe that religion, generally speaking, has been a curse to mankind — that its modest and greatly overestimated services on the ethical side have been more than overcome by the damage it has done to clear and honest thinking.
I believe that no discovery of fact, however trivial, can be wholly useless to the race, and that no trumpeting of falsehood, however virtuous in intent, can be anything but vicious.
I believe that all government is evil, in that all government must necessarily make war upon liberty and the democratic form is as bad as any of the other forms.
I believe that the evidence for immortality is no better than the evidence of witches, and deserves no more respect.
I believe in the complete freedom of thought and speech — alike for the humblest man and the mightiest, and in the utmost freedom of conduct that is consistent with living in organized society.
I believe in the capacity of man to conquer his world, and to find out what it is made of, and how it is run.
I believe in the reality of progress.
I —But the whole thing, after all, may be put very simply. I believe that it is better to tell the truth than to lie. I believe that it is better to be free than to be a slave. And I believe that it is better to know than be ignorant.

Manasseh: On the Speech and Gesture of Jesus
Jesus, The Son of Man (1928)
Context: I admired Him as a man rather than as a leader. He preached something beyond my liking, perhaps beyond my reason. And I would have no man preach to me.
I was taken by His voice and His gestures, not by the substance of His speech. He charmed me but never convinced me; for He was too vague, too distant and obscure to reach my mind.
I have known other men like Him. They are never constant nor are they consistent. It is with eloquence not with principles that they hold your ear and your passing thought, but never the core of your heart.

Stephen Hero (1944)
Context: This triviality made him think of collecting many such moments together in a book of epiphanies. By an epiphany he meant a sudden spiritual manifestation, whether in the vulgarity of speech or of gesture or in a memorable phase of the mind itself. He believed that it was for the man of letters to record these epiphanies with extreme care, seeing that they themselves are the most delicate and evanescent of moments. He told Cranly that the clock of the Ballast Office was capable of an epiphany. Cranly questioned the inscrutable dial of the Ballast Office with his no less inscrutable countenance:
—Yes, said Stephen. I will pass it time after time, allude to it, refer to it, catch a glimpse of it. It is only an item in the catalogue of Dublin's street furniture. Then all at once I see it and I know at once what it is: epiphany.

"For the Defense Written for the Associated Press, for use in my obituary" (20 November 1940)
1940s–present
Context: Having lived all my life in a country swarming with messiahs, I have been mistaken, perhaps quite naturally, for one myself, especially by the others. It would be hard to imagine anything more preposterous. I am, in fact, the complete anti-Messiah, and detest converts almost as much as I detest missionaries. My writings, such as they are, have had only one purpose: to attain for H. L. Mencken that feeling of tension relieved and function achieved which a cow enjoys on giving milk. Further than that, I have had no interest in the matter whatsoever. It has never given me any satisfaction to encounter one who said my notions had pleased him. My preference has always been for people with notions of their own. I have believed all my life in free thought and free speech—up to and including the utmost limits of the endurable.

Journals A 126 (March 1836)
1830s, The Journals of Søren Kierkegaard, 1830s
Context: One could construe the life of man as a great discourse in which the various people represent different parts of speech (the same might apply to states). How many people are just adjectives, interjections, conjunctions, adverbs? How few are substantives, active verbs, how many are copulas? Human relations are like the irregular verbs in a number of languages where nearly all verbs are irregular.

1860s, The Constitution of the United States: Is It Pro-Slavery or Anti-Slavery? (1860)
Context: The American people in the Northern States have helped to enslave the black people. Their duty will not have been done till they give them back their plundered rights. Reference was made at the City Hall to my having once held other opinions, and very different opinions to those I have now expressed. An old speech of mine delivered fourteen years ago was read to show — I know not what. Perhaps it was to show that I am not infallible. If so, I have to say in defense, that I never pretended to be.

Interview with Laura Knoy, New Hampshire Public Radio (5 November 2003)
Context: I think General Eisenhower was exactly right, I think we should be concerned about the military-industrial complex. I think if you look at where the country is today you've consolidated all these defense firms into just a few large firms — like Halliburton — and with contracts and contacts at the top level of government. You've got most of the retired generals are one way or another associated with the defense firms — that's the reason that you'll find very few of them speaking out in any public way — I'm not. When I got out I determined I wasn't going to sell arms, I was going to do as little as possible with the Department of Defense because I just figured it was time to make a new start. But I think the military-industrial complex does wield a lot of influence — I'd like to see us create a different complex. And I'm going to be talking about foreign policy in a major speech tomorrow, but we need to create an agency that is not about waging war but about creating conditions for peace around the world. We need some people who will be advocates for peace, advocates for economic development abroad, not just advocates for better weapon systems. So we need to create countervailing power to the military-industrial complex.

"Quotes", The Educated Imagination (1963), Talk 2: The Singing School
Context: [L]iterature not only leads us toward the regaining of identity, but it also separates this state from its opposite, the world we don't like and want to get away from... We have to look at the figures of speech a writer uses, his images and symbols, to realize that underneath all the complexity of human life that uneasy stare at an alien nature is still haunting us, and the problem of surmounting it is still with us.... Literature is still doing the same job that mythology did earlier, but filling in its huge cloudy shapes with sharper lights and deeper shadows.

Quotes 1990s, 1995-1999, The Common Good (1998)
Context: Property rights are not like other rights, contrary to what Madison and a lot of modern political theory says. If I have the right to free speech, it doesn't interfere with your right to free speech. But if I have property, that interferes with your right to have that property, you don't have it, I have it. So the right to property is very different from the right to freedom of speech. This is often put very misleadingly about rights of property; property has no right. But if we just make sense out of this, maybe there is a right to property, one could debate that, but it's very different from other rights.

Nobel Prize acceptance speech (1962)
Context: Literature was not promulgated by a pale and emasculated critical priesthood singing their litanies in empty churches — nor is it a game for the cloistered elect, the tinhorn mendicants of low calorie despair.
Literature is as old as speech. It grew out of human need for it, and it has not changed except to become more needed.
The skalds, the bards, the writers are not separate and exclusive. From the beginning, their functions, their duties, their responsibilities have been decreed by our species.

Source: Zen and the Art of Motorcycle Maintenance (1974), Ch. 30
Context: It is an immortal dialogue, strange and puzzling at first, but then hitting you harder and harder, like truth itself. What Phædrus has been talking about as Quality, Socrates appears to have described as the soul, self-moving, the source of all things. There is no contradiction. There never really can be between the core terms of monistic philosophies. The One in India has got to be the same as the One in Greece. If it's not, you've got two. The only disagreements among the monists concern the attributes of the One, not the One itself. Since the One is the source of all things and includes all things in it, it cannot be defined in terms of those things, since no matter what thing you use to define it, the thing will always describe something less than the One itself. The One can only be described allegorically, through the use of analogy, of figures of imagination and speech. Socrates chooses a heaven-and-earth analogy, showing how individuals are drawn toward the One by a chariot drawn by two horses.

Speech to the Empire Rally of Youth at the Royal Albert Hall (18 May 1937), quoted in Service of Our Lives (1937), pp. 166-167.
1937
Context: The torch I would hand to you, and ask you to pass from hand to hand along the pathways of the Empire, is a Christian truth rekindled anew in each ardent generation. Use men as ends and never merely as means; and live for the brotherhood of man, which implies the Fatherhood of God. The brotherhood of man to-day is often denied and derided and called foolishness, but it is, in fact, one of the foolish things of the world which God has chosen to confound the wise, and the world is confounded by it daily. We may evade it, we may deny it; but we shall find no rest for our souls, or will the world until we acknowledge it as the ultimate wisdom. That is the message I have tried to deliver as Prime Minister in a hundred speeches.

Perelandra (1943)
Context: And now, by a transition which he did not notice, it seemed that what had begun as speech was turned into sight, or into something that can be remembered only as if it were seeing. He thought he saw the Great Dance. It seemed to be woven out of the intertwining undulation of many cords or bands of light, leaping over and under one another and mutually embraced in arabesques and flower-like subtleties. Each figure as he looked at it became the master-figure or focus of the whole spectacle, by means of which his eye disentangled all else and brought it into unity — only to be itself entangled when he looked to what he had taken for mere marginal decorations and found that there also the same hegemony was claimed, and the claim made good, yet the former pattern thereby disposed but finding in its new subordination a significance greater than that which it had abdicated. He could see also (but the word "seeing" is now plainly inadequate) wherever the ribbons or serpents of light intersected minute corpuscles of momentary brightness: and he knew somehow that these particles were the secular generalities of which history tells — people, institutions, climates of opinion, civilizations, arts, sciences and the like — ephemeral coruscations that piped their short song and vanished. The ribbons or cords themselves, in which millions of corpuscles lived and died, were the things of some different kind. At first he could not say what. But he knew in the end that most of them were individual entities. If so, the time in which the Great Dance proceeds is very unlike time as we know it. Some of the thinner more delicate cords were the beings that we call short lived: flowers and insects, a fruit or a storm of rain, and once (he thought) a wave of the sea. Others were such things we think lasting: crystals, rivers, mountains, or even stars. Far above these in girth and luminosity and flashing with colours form beyond our spectrum were the lines of personal beings, yet as different from one another in splendour as all of them from the previous class. But not all the cords were individuals: some of them were universal truths or universal qualities. It did not surprise him then to find that these and the persons were both cords and both stood together as against the mere atoms of generality which lived and died in the clashing of their streams: But afterwards, when he came back to earth, he wondered. And by now the thing must have passed together out of the region of sight as we understand it. For he says that the whole figure of these enamored and inter-inanimate circlings was suddenly revealed as the mere superficies of a far vaster pattern in four dimensions, and that figure as the boundary of yet others in other worlds: till suddenly as the movement grew yet swifter, the interweaving yet more ecstatic, the relevance of all to all yet more intense, as dimension was added to dimension and that part of him which could reason and remember was dropped further and further behind that part of him which saw, even then, at the very zenith of complexity, complexity was eaten up and faded, as a thin white cloud fades into the hard blue burning of sky, and all simplicity beyond all comprehension, ancient and young as spring, illimitable, pellucid, drew him with cords of infinite desire into its own stillness. He went up into such a quietness, a privacy, and a freshness that at the very moment when he stood farthest from our ordinary mode of being he had the sense of stripping off encumbrances and awaking from a trance, and coming to himself. With a gesture of relaxation he looked about him…

1940s, State of the Union Address — The Four Freedoms (1941)
Context: In the future days which we seek to make secure, we look forward to a world founded upon four essential human freedoms.
The first is freedom of speech and expression — everywhere in the world.
The second is freedom of every person to worship God in his own way — everywhere in the world.
The third is freedom from want, which, translated into world terms, means economic understandings which will secure to every nation a healthy peacetime life for its inhabitants — everywhere in the world.
The fourth is freedom from fear, which, translated into world terms, means a world-wide reduction of armaments to such a point and in such a thorough fashion that no nation will be in a position to commit an act of physical aggression against any neighbor — anywhere in the world.
That is no vision of a distant millennium. It is a definite basis for a kind of world attainable in our own time and generation.
