Russell, New Hopes for a Changing World (1951). Compare also: "The best lack all conviction, while the worst / Are full of passionate intensity." W. B. Yeats, The Second Coming (1919).

Context: Suppose atomic bombs had reduced the population of the world to one brother and one sister, should they let the human race die out? I do not know the answer, but I do not think it can be in the affirmative merely on the ground that incest is wicked.
"What We Must Do"
1920s, Why I Am Not a Christian (1927)
Context: The whole conception of God is a conception derived from the ancient Oriental despotisms. It is a conception quite unworthy of free men. When you hear people in church debasing themselves and saying that they are miserable sinners, and all the rest of it, it seems contemptible and not worthy of self-respecting human beings. We ought to stand up and look the world frankly in the face. We ought to make the best we can of the world, and if it is not so good as we wish, after all it will still be better than what these others have made of it in all these ages. A good world needs knowledge, kindliness, and courage; it does not need a regretful hankering after the past, or a fettering of the free intelligence by the words uttered long ago by ignorant men.
Essay Do We Survive Death? (1936)
1930s
Context: It is only when we think abstractly that we have such a high opinion of man. Of men in the concrete, most of us think the vast majority very bad. Civilized states spend more than half their revenue on killing each other's citizens. Consider the long history of the activities inspired by moral fervour: human sacrifices, persecutions of heretics, witch-hunts, pogroms leading up to wholesale extermination by poison gases … Are these abominations, and the ethical doctrines by which they are prompted, really evidence of an intelligent Creator? And can we really wish that the men who practised them should live for ever? The world in which we live can be understood as a result of muddle and accident; but if it is the outcome of a deliberate purpose, the purpose must have been that of a fiend. For my part, I find accident a less painful and more plausible hypothesis.
An Outline of Philosophy Ch.15 The Nature of our Knowledge of Physics (1927)
1920s
Context: Physics is mathematical not because we know so much about the physical world, but because we know so little: it is only its mathematical properties that we can discover.
1900s, "The Study of Mathematics" (November 1907)
Context: Real life is, to most men, a long second-best, a perpetual compromise between the ideal and the possible; but the world of pure reason knows no compromise, no practical limitations, no barrier to the creative activity embodying in splendid edifices the passionate aspiration after the perfect from which all great work springs. Remote from human passions, remote even from the pitiful facts of nature, the generations have gradually created an ordered cosmos, where pure thought can dwell as in its natural home, and where one, at least, of our nobler impulses can escape from the dreary exile of the actual world.
An Outline of Philosophy Ch.4 Language (1927)
1920s
Context: Written words differ from spoken words in being material structures. A spoken word is a process in the physical world, having an essential time-order; a written word is a series of pieces of matter, having an essential space-order.
The Analysis of Mind (1921), Lecture IX: Memory, p. 159
1920s
Context: There is no logical impossibility in the hypothesis that the world sprang into being five minutes ago, exactly as it then was, with a population that "remembered" a wholly unreal past. There is no logically necessary connection between events at different times; therefore nothing that is happening now or will happen in the future can disprove the hypothesis that the world began five minutes ago.
“The secret of happiness is to face the fact that the world is horrible, horrible, horrible.”

"Fear, the Foundation of Religion"
1920s, Why I Am Not a Christian (1927)
Source: Why I Am Not a Christian and Other Essays on Religion and Related Subjects
Context: Religion is based, I think, primarily and mainly upon fear. It is partly the terror of the unknown and partly, as I have said, the wish to feel that you have a kind of elder brother who will stand by you in all your troubles and disputes. Fear is the basis of the whole thing – fear of the mysterious, fear of defeat, fear of death. Fear is the parent of cruelty, and therefore it is no wonder if cruelty and religion have gone hand-in-hand. It is because fear is at the basis of those two things. In this world we can now begin a little to understand things, and a little to master them by the help of science, which has forced its way step by step against the Christian religion, against the churches, and against the opposition of all the old precepts. Science can help us to get over this craven fear in which mankind has lived for so many generations. Science can teach us, and I think our own hears can teach us, no longer to look around for imaginary supports, no longer to invent allies in the sky, but rather to look to our own efforts here below to make this world a fit place to live in, instead of the sort of place that the churches in all these centuries have made it.
“Is there any knowledge in the world which is so certain that no reasonable man could doubt it?”

"The Emotional Factor"Religion is based, I think, primarily and mainly upon fear.
Often paraphrased as "The Christian religion has been and still is the principal enemy of moral progress in the world."
1920s, Why I Am Not a Christian (1927)
Context: You find as you look around the world that every single bit of progress of humane feeling, every improvement in the criminal law, every step toward the diminution of war, every step toward better treatment of the colored races, or even mitigation of slavery, every moral progress that there has been in the world, has been consistently opposed by the organized churches of the world. I say quite deliberately that the Christian religion, as organized in its churches, has been and still is the principal enemy of moral progress in the world.
“How much longer is the world willing to endure this spectacle of wanton cruelty?”
"Message from Bertrand Russell to the International Conference of Parlimentarians in Cairo, February 1970," reprinted in The New York Times (23 February 1970)
1960s
Context: The tragedy of the people of Palestine is that their country was "given" by a foreign power to another people for the creation of a new state. The result was that many hundreds of thousands of innocent people were made permanently homeless. With every new conflict their numbers increased. How much longer is the world willing to endure this spectacle of wanton cruelty? It is abundantly clear that the refugees have every right to the homeland from which they were driven, and the denial of this right is at the heart of the continuing conflict. No people anywhere in the world would accept being expelled en masse from their country; how can anyone require the people of Palestine to accept a punishment which nobody else would tolerate? A permanent just settlement of the refugees in their homeland is an essential ingredient of any genuine settlement in the Middle East.
