Antisthenes ... was asked on one occasion what learning was the most necessary, and he replied, "To unlearn one's bad habits."

The Ideal Man of the eighteenth century was the Rationalist; of the seventeenth, the Christian Stoic; of the Renaissance, the Free Individual; of the Middle Ages, the Contemplative Saint. And what is our Ideal Man? On what grand and luminous mythological figure does contemporary humanity attempt to model itself? The question is embarrassing. Nobody knows. And, in spite of all the laudable efforts of the Institute for Intellectual Co-operation to fabricate an acceptable Ideal Man for the use of Ministers of Education, nobody, I suspect, will know until such time as a major poet appears upon the scene with the unmistakable revelation. Meanwhile, one must be content to go on piping up for reason and realism and a certain decency.

Philosophers are often like little children, who first scribble random lines on a piece of paper with their pencils, and now ask an adult "What is that?"

An authorship that began with Either/Or and advanced step by step seeks here its decisive place of rest, at the foot of the altar, where the author, personally most aware of his own imperfections and guilt, certainly does not call himself a truth-witness but only a singular kind of poet and thinker who, without authority, has had nothing new to bring but “has wanted once again to read through, if possible in a more inward way, the original text handed down from the fathers.

Mercy to the guilty is cruelty to the innocent.

I have never seen a class so deeply demoralised, so incurably debased by selfishness, so corroded within, so incapable of progress, as the English bourgeoisie; and I mean by this, especially the bourgeoisie proper, particularly the Liberal, Corn Law repealing bourgeoisie. For it nothing exists in this world, except for the sake of money, itself not excluded. It knows no bliss save that of rapid gain, no pain save that of losing gold. In the presence of this avarice and lust of gain, it is not possible for a single human sentiment or opinion to remain untainted.

It seldom happens, however, that a great proprietor is a great improver.

"Optimism," said Cacambo, "What is that?" "Alas!" replied Candide, "It is the obstinacy of maintaining that everything is best when it is worst!

"A fair day's wages for a fair day's work": it is as just a demand as governed men ever made of governing. It is the everlasting right of man.

Dear youths, I warn you cherish peace divine, And in your hearts lay deep these words of mine.

As to the species of exercise, I advise the gun. While this gives a moderate exercise to the body, it gives boldness, enterprise, and independence to the mind. Games played with the ball, and others of that nature, are too violent for the body, and stamp no character on the mind. Let your gun therefore be the constant companion of your walks. Never think of taking a book with you.

All media of communications are cliches serving to enlarge man's scope of action, his patterns of associations and awareness. These media create environments that numb our powers of attention by sheer pervasiveness.

The rest of the story, to Grand's thinking, was very simple. The common lot of married couples. You get married, you go on loving a bit longer, you work. And you work so hard that it makes you forget to love.

I think I can hardly overrate the malignity of the principles of Protestant ascendancy, as they affect Ireland; or of Indianism, as they affect these countries, and as they affect Asia; or of Jacobinism, as they affect all Europe, and the state of human society itself. The last is the greatest evil.

Whether directly or indirectly all nations are originally nothing but Indian colonies... the oriental antiquity could, if we consented to deepen it, bring us back more safely towards the divine....

Big industry, and the limitless expansion of production which it makes possible, bring within the range of feasibility a social order in which so much is produced that every member of society will be in a position to exercise and develop all his powers and faculties in complete freedom. It thus appears that the very qualities of big industry which, in our present-day society, produce misery and crises are those which, in a different form of society, will abolish this misery and these catastrophic depressions.We see with the greatest clarity: (i) That all these evils are from now on to be ascribed solely to a social order which no longer corresponds to the requirements of the real situation; and (ii) That it is possible, through a new social order, to do away with these evils altogether.

To be sure, risks abound; but no one is proposing compassionate stewardship of ecosystems by philosophers. Humans are capable of choosing our own future pain-sensitivity too; but any species-wide genomic shift in human pain tolerance will depend on the willingness of prospective parents to use preimplantation genetic screening.

It is important to understand what I mean by semiosis. All dynamic action, or action of brute force, physical or psychical, either takes place between two subjects, - whether they react equally upon each other, or one is agent and the other patient, entirely or partially, - or at any rate is a resultant of such actions between pairs. But by "semiosis" I mean, on the contrary, an action, or influence, which is, or involves, a cooperation of three subjects, such as a sign, its object, and its interpretant, this tri-relative influence not being in any way resolvable into actions between pairs.

Earth is a ball that is over 12,000 kilometres in diameter, and if it were modelled into an object the size of a billiard ball, with all its surface unevenness reproduced exactly to scale, the model would be smoother than an ordinary billiard ball and the ocean would be an all but unnoticeable mist of dampness over 70 percent of its surface.

The supreme task of the physicist is to arrive at those universal elementary laws from which the cosmos can be built up by pure deduction. There is no logical path to these laws; only intuition, resting on sympathetic understanding of experience, can reach them. In this methodological uncertainty, one might suppose that there were any number of possible systems of theoretical physics all equally well justified; and this opinion is no doubt correct, theoretically. But the development of physics has shown that at any given moment, out of all conceivable constructions, a single one has always proved itself decidedly superior to all the rest.

When Fortune is on our side, popular favor bears her company.

To believe is to know you believe, and to know you believe is not to believe.

In the same way that the figure of the peasant tends to disappear, so too does the figure of the industrial worker, the service industry worker and all other separate categories.

The love of God consists in an ardent desire to procure the general welfare, and reason teaches me that there is nothing which contributes more to the general welfare of mankind than the perfection of reason.

We are members of this Head, and this body cannot be decapitated. If the Head is in glory forever, so too are the members in glory forever, that Christ may be undivided forever.

Every parting gives a foretaste of death, every reunion a hint of the resurrection.

The hatred that men bear to privilege increases in proportion as privileges become fewer and less considerable, so that democratic passions would seem to burn most fiercely just when they have least fuel. I have already given the reason for this phenomenon. [all conditions are unequal, no inequality is so great as to offend the eye, whereas the slightest dissimilarity is odious in the midst of general uniformity; the more complete this uniformity is, the more insupportable the sight of such a difference becomes.] Hence it is natural that the love of equality should constantly increase together with equality itself, and that it should grow by what it feeds on.

It is necessary that every man be surpassingly temperate. That person would most of all be a man of this sort if he were superior to money, which is what corrupts all men, and if, without caring about his life, he bestowed his pains on things that are just and pursued virtue.

In future, nerve cell responsiveness to naturally occurring endogenous opioids can be increased via receptor enrichment in the brain too. In principle, we can modulate their lifelong "overexpression", intermittently heightened (or gently diminished) by whatever kinds of personal and environmental contingencies we judge fit. Both functionally and anatomically, our reward pathways can be made "bigger and better". But intelligent emotional self-mastery will involve re-engineering the mind-brain so we derive the most intense rewards from activities we deem most lastingly worthwhile: i.e. prioritising our higher-order desires over legacy first-order appetites. Natural selection has "encephalised" our emotions to benefit our genes. Rational agents can "re-encephalise" our emotions to benefit us.

Those who claim to care about the wellbeing of human beings and the preservation of our environment should become vegetarians for that reason alone. They would thereby increase the amount of grain available to feed people elsewhere, reduce pollution, save water and energy, and cease contributing to the clearing of forests; moreover, since a vegetarian diet is cheaper than one based on meat dishes, they would have more money available to devote to famine relief, population control, or whatever social or political cause they thought most urgent. ... when nonvegetarians say that "human problems come first" I cannot help wondering what exactly it is that they are doing for human beings that compels them to continue to support the wasteful, ruthless exploitation of farm animals.

Every hero becomes a bore at last.

He made one of Antipater's recommendation a judge; and perceiving afterwards that his hair and beard were coloured, he removed him, saying, "I could not think one that was faithless in his hair could be trusty in his deeds."

He did not, and could not, understand the meaning of words apart from their context. Every word and action of his was the manifestation of an activity unknown to him, which was his life.

The Value or WORTH of a man, is as of all other things, his Price; that is to say, so much as would be given for the use of his Power...

Never spend your money before you have it.

It shews the anxiety of the great men who influenced the conduct of affairs at that great event, to make the Revolution a parent of settlement, and not a nursery of future revolutions.

Democracy can hardly be expected to flourish in societies where political and economic power is being progressively concentrated and centralized. But the progress of technology has led and is still leading to just such a concentration and centralization of power.

To the rest of the Galaxy, if they are aware of us at all, Earth is but a pebble in the sky. To us it is home, and all the home we know.

Optimism is an alienated form of faith, pessimism an alienated form of despair. If one truly responds to man and his future, ie, concernedly and "responsibly." one can respond only by faith or by despair. Rational faith as well as rational despair are based on the most thorough, critical knowledge of all the factors that are relevant for the survival of man.

Such taxes [upon the necessaries of life], when they have grown up to a certain height, are a curse equal to the barrenness of the earth and the inclemency of the heavens; and yet it is in the richest and most industrious countries that they have been most generally imposed. No other countries could support so great a disorder.

Powerful indeed is the empire of habit.

The rights of men to the use of land are not joint rights: they are equal rights. Were there only one man on earth, he would have a right to the use of the whole earth or any part of the earth. When there is more than one man on earth, the right to the use of land that any one of them would have, were he alone, is not abrogated: it is only limited. The right of each to the use of land is still a direct, original right, which he holds of himself, and not by the gift or consent of the others; but it has become limited by the similar rights of the others, and is therefore an equal right.

Religion should be .... successively freed from all statutes based on history, and one purely moral religion rule over all, in order that God might be all in all. The veil must fall. The leading-string of sacred tradition with all its appendices becomes by degrees useless, and at last a fetter ... The humiliating difference between laymen and clergymen must disappear, and equality spring from true liberty. All this, however, must not be expected from an exterior revolution, which acts violently, and depends upon fortune In the principle of pure moral religion, which is a sort of divine revelation constantly taking place in the soul of man, must be sought the ground for a passage to the new order of things, which will be accomplished by slow and successive reforms.

The aim of protection, in short, is to prevent the bringing into a country of things in themselves useful and valuable, in order to compel the making of such things. But what all mankind in the individual affairs of every-day life, regard as to be desired is not the making of things, but the possession of things.

I sometimes wondered what the use of any of the arts was. The best thing I could come up with was what I call the canary in the coal mine theory of the arts. This theory says that artists are useful to society because they are so sensitive. They are super-sensitive. They keel over like canaries in poison coal mines long before more robust types realize that there is any danger whatsoever.
