One thing underpins, makes consistent, and gives meaning to all our other activities on behalf of animals. This one thing is that we take responsibility for our own lives, and make them as free of cruelty as we can. The first step is that we cease to eat animals. Many people who are opposed to cruelty to animals draw the line at becoming a vegetarian. It was of such people that Oliver Goldsmith, the eighteenth-century humanitarian essayist, wrote: "They pity, and they eat the objects of their compassion."

"In the light, the earth remains our first and our last love. Our brothers are breathing under the same sky as we; justice is a living thing. Now is born that strange joy which helps one live and die, and which we shall never again postpone to a later time."

Suffering, sad "female humanity!" What are these feelings which they are taught to consider as disgraceful, to deny to themselves? What form do the Chinese feet assume when denied their proper development? If the young girls of the "higher classes," who never commit a false step, whose justly earned reputations were never sullied even by the stain which the fruit of mere "knowledge of good and evil" leaves behind, were to speak, and say what are their thoughts employed upon, their thoughts, which alone are free, what would they say?

Whoever does not philosophize for the sake of philosophy, but rather uses philosophy as a means, is a sophist.

We used to pay too little attention to utopias, or even disregard them altogether, saying with regret they were impossible of realisation. Now indeed they seem to be able to be brought about far more easily than we supposed, and we are actually faced by an agonising problem of quite another kind: how can we prevent their final realisation? ... Utopias are more realisable than those 'realist politics' that are only the carefully calculated policies of office-holders, and towards utopias we are moving. But it is possible that a new age is already beginning, in which cultured and intelligent people will dream of ways to avoid ideal states and to get back to a society that is less 'perfect' and more free.

When we leave you and assemble together by ourselves, we talk freely about his sayings and doings, treating them with the respect which they deserve: in your presence deep silence is observed about him, and thus you lose that greatest of pleasures, the hearing the praises of your son, which I doubt not you would be willing to hand down to all future ages, had you the means of so doing, even at the cost of your own life.

Harvard now, I think, suffers from a kind of self-idolatry, that it needs to be critical of itself in order to grow. And again, if you can be in contact with the best of its past, then it's got a chance. But if it just remains well adjusted to the status quo, generating careerist and opportunist students rather than critically oriented students who have a heart and soul, concerned about suffering here and around the world - then Harvard has a chance. I'm not giving up on Harvard, but I am making my way to New York.

Reading the morning newspaper is the realist's morning prayer. One orients one's attitude toward the world either by God or by what the world is. The former gives as much security as the latter, in that one knows how one stands.

If you believe what you like in the gospels, and reject what you don't like, it is not the gospel you believe, but yourself.

Intolerance is the besetting sin of moral fervour.

Out from the heart of Nature rolled The burdens of the Bible old.

When the real is no longer what it was, nostalgia assumes its full meaning. "The Precession of Simulacra,"

This is still the strangest thing in all man's travelling, that he should carry about with him incongruous memories.

A very few, as heroes, patriots, martyrs, reformers in the great sense, and men, serve the State with their consciences also, and so necessarily resist it for the most part; and they are commonly treated by it as enemies.

Regarding the plan to collect my writings in volumes, I am quite cool and not at all eager about it because, roused by a Saturnian hunger, I would rather see them all devoured. For I acknowledge none of them to be really a book of mine, except perhaps the one On the Bound Will and the Catechism.

Pure Mathematics is the class of all propositions of the form "p implies q," where p and q are propositions containing one or more variables, the same in the two propositions, and neither p nor q contains any constants except logical constants. And logical constants are all notions definable in terms of the following: Implication, the relation of a term to a class of which it is a member, the notion of such that, the notion of relation, and such further notions as may be involved in the general notion of propositions of the above form. In addition to these, mathematics uses a notion which is not a constituent of the propositions which it considers, namely the notion of truth.

There are some mixt bodies, from which it has not been yet made appear, that any degree of fire can separate either salt, or sulphur, or mercury, much less all the three. The most obvious instance of this truth is gold, which is a body so fixed, and wherein the elementary ingredients (if it have any) are so firmly united to each other, that we find not in the operations, wherein gold is exposed to the fire, how violent soever, that it does discernably so much as lose of its fixedness or weight, so far is it from being dissipated into those principles, whereof one at least is acknowledged to be fugitive enough.

While the positivists were proclaiming the end "once and for all" of unverifiable metaphysical systems and speculative philosophy in general, new doctrines in flagrant contradiction to those ideals have sprung up one after the other. Positivists see no more in this development than evidence of human stupidity, not any reflection on themselves.

Reaching and understanding is the process of bringing about an agreement on the presupposed basis of validity claims that are mutually recognized.

Literature is the effort of man to indemnify himself for the wrongs of his condition.

Sex also concentrates the mind wonderfully, and that is why civilised man is so obsessed by it. It enables him to "savour every fraction of an inch," not merely of the act of sexual intercourse, but of living itself. But that, of course, only underlines the basic problem: after coitus, "man becomes sad," because he quickly returns to his unconcentrated and defocused state. In sexual excitement, it is the spirit itself that becomes erect, and becomes capable of penetrating the meaning of life. Normal consciousness is limp and flaccid; its attitude towards reality is defensive. This is what Sartre called contingency, that feeling of being at the mercy of chance.

I have been writing & speaking what were once called novelties, for twenty five or thirty years, & have not now one disciple. Why? Not that what I said was not true; not that it has not found intelligent receivers but because it did not go from any wish in me to bring men to me, but to themselves. I delight in driving them from me. What could I do, if they came to me? - they would interrupt and encumber me. This is my boast that I have no school & no follower. I should account it a measure of the impurity of insight, if it did not create independence.

Whenever the therapist stands with society, he will interpret his work as adjusting the individual and coaxing his 'unconscious drives' into social respectability. But such 'official psychotherapy' lacks integrity and becomes the obedient tool of armies, bureaucracies, churches, corporations, and all agencies that require individual brainwashing. On the other hand, the therapist who is really interested in helping the individual is forced into social criticism. This does not mean that he has to engage directly in political revolution; it means that he has to help the individual in liberating himself from various forms of social conditioning, which includes liberation from hating this conditioning - hatred being a form of bondage to its object.

Once the philosophical foundation of democracy has collapsed, the statement that dictatorship is bad is rationally valid only for those who are not its beneficiaries, and there is no theoretical obstacle to the transformation of this statement into its opposite.

We ourselves are the entities to be analyzed.

The real struggle is not between East and West, or capitalism and communism, but between education and propaganda.

A further threat to liberalism has to do with the mode of cognition that we call modern natural science. The early liberals were very closely aligned with the founders of modern natural science, people like Bacon and Descartes and Newton, who believed that there was an objective world beyond our subjective consciousnesses, that we could perceive this world through the experimental method, and then come to manipulate it. Natural science gave us technology... that made the world much more habitable, by conquering disease, by inventing things that vastly increased human productivity. So... it's closely related to the wealth, and... the safety and comfort of a modern economically developed world.

It is sometimes maintained that racial mixture is biologically undesirable. There is no evidence whatever for this view. Nor is there, apparently, any reason to think that Negroes are congenitally less intelligent than white people, but as to that it will be difficult to judge until they have equal scope and equally good social conditions.

A good mind possesses a kingdom.

So long as man remains free he strives for nothing so incessantly and so painfully as to find someone to worship. But man seeks to worship what is established beyond dispute, so that all men would agree at once to worship it. For these pitiful creatures are concerned not only to find what one or the other can worship, but to find community of worship is the chief misery of every man individually and of all humanity from the beginning of time. For the sake of common worship they've slain each other with the sword. They have set up gods and challenged one another, 'Put away your gods and come and worship ours, or we will kill you and your gods!' And so it will be to the end of the world, even when gods disappear from the earth; they will fall down before idols just the same.

There has been progress in design, but not progress in accomplishment.

Have courage, or cunning, when you deal with an enemy.

The real point at issue always is Turkey in Europe - the great peninsula to the south of the Save and Danube. This splendid territory [the Balkans] has the misfortune to be inhabited by a conglomerate of different races and nationalities, of which it is hard to say which is the least fit for progress and civilization. Slavonians, Greeks, Wallachians, Arnauts, twelve millions of men, are all held in submission by one million of Turks, and up to a recent period, it appeared doubtful whether, of all these different races, the Turks were not the most competent to hold the supremacy which, in such a mixed population, could not but accrue to one of these nationalities.

The tiger that assails me is in the right, and I who strike him down am also in the right. I defend against him not my right, but myself.

It should be remembered, as an axiom of eternal truth in politics, that whatever power in any government is independent, is absolute also; in theory only, at first, while the spirit of the people is up, but in practice, as fast as that relaxes. Independence can be trusted nowhere but with the people in mass. They are inherently independent of all but moral law.

This is the pure form of servitude: to exist as an instrument.

I am not asking anyone to accept Christianity if his best reasoning tells him that the weight of the evidence is against it.

It is sweet and honorable to die for one's country.

But oppression by your Mock-Superiors well shaken off, the grand problem yet remains to solve: That of finding government by your Real-Superiors! Alas, how shall we ever learn the solution of that, benighted, bewildered, sniffing, sneering, godforgetting unfortunates as we are? It is a work for centuries; to be taught us by tribulations, confusions, insurrections, obstructions; who knows if not by conflagration and despair! It is a lesson inclusive of all other lessons; the hardest of all lessons to learn.

Under all speech that is good for anything there lies a silence that is better.

Again, Amyclas the Heracleotean, one of Plato's familiars, and Menæchmus, the disciple, indeed, of Eudoxus, but conversant with Plato, and his brother Dinostratus, rendered the whole of geometry as yet more perfect. But Theudius, the Magnian, appears to have excelled, as well in mathematical disciplines, as in the rest of philosophy. For he constructed elements egregiously, and rendered many particulars more universal. Besides, Cyzicinus the Athenian, flourished at the same period, and became illustrious in other mathematical disciplines, but especially in geometry. These, therefore, resorted by turns to the Academy, and employed themselves in proposing common questions.

Do you suppose that you can do the things you do now, and yet be a philosopher? Do you suppose that you can eat in the same fashion, drink in the same fashion, give way to anger and to irritation, just as you do now?

No man can visualize four dimensions, except mathematically ... I think in four dimensions, but only abstractly. The human mind can picture these dimensions no more than it can envisage electricity. Nevertheless, they are no less real than electro-magnetism, the force which controls our universe, within, and by which we have our being.

Imagination is not an empirical or superadded power of consciousness, it is the whole of consciousness as it realizes its freedom.

What a monument of human smallness is this idea of the philosopher king. What a contrast between it and the simplicity of humaneness of Socrates, who warned the statesmen against the danger of being dazzled by his own power, excellence, and wisdom, and who tried to teach him what matters most - that we are all frail human beings. What a decline from this world of irony and reason and truthfulness down to Plato's kingdom of the sage whose magical powers raise him high above ordinary men; although not quite high enough to forgo the use of lies, or to neglect the sorry trade of every shaman - the selling of spells, of breeding spells, in exchange for power over his fellow-men.

Believing with you that religion is a matter which lies solely between man and his God, that he owes account to none other for his faith or his worship, that the legislative powers of government reach actions only, and not opinions, I contemplate with sovereign reverence that act of the whole American people which declared that their legislature should "make no law respecting an establishment of religion, or prohibiting the free exercise thereof," thus building a wall of separation between church and State.

Nowadays three witty turns of phrase and a lie make a writer.
