Man differs from other animals in one very important respect, and that is that he has some desires which are, so to speak, infinite, which can never be fully gratified, and which would keep him restless even in Paradise. The boa constrictor, when he has had an adequate meal, goes to sleep, and does not wake until he needs another meal. Human beings, for the most part, are not like this.

The decisions of law courts should never be printed: in the long run, they form a counterauthority to the law.

Pain and suffering are always inevitable for a large intelligence and a deep heart. The really great men must, I think, have great sadness on Earth.

I am here to speak on freedom of speech. It is a great topic, and I am going to make my speech as free as possible. But you know that this cannot be done, for when anyone announces that he is going to speak his mind freely, everyone is frightened. This shows that there is no such thing as true freedom of speech. No one can afford to let his neighbors know what he is thinking about them. Society can exist only on the basis that there is some amount of polished lying and that no one says exactly what he thinks.

Why has the Revolution of France been stained with crimes, which the Revolution of the United States of America was not? Men are physically the same in all countries; it is education that makes them different. Accustom a people to believe that priests or any other class of men can forgive sins, and you will have sins in abundance.

I found Randi likable and plausible; the only thing that bothered me was the sweeping and intense nature of his skepticism. He was obviously working from the premise that all paranormal phenomena, without exception, are fakes or delusions. He seemed to take to take it for granted that all of us - there were also two women present - shared his opinions, and he made jovial, disparaging remarks about psychics and other such weirdos. I began to get the uncomfortable feeling of a Jew who has accidentally walked into a Nazi meeting, or a Jehovah's Witness at a convention of militant atheists. As a supposedly scientific psychic investigator, Randi struck me as being oddly fixed in his opinions.

Every man has his own circle composed of trees, animals, men, ideas, and he is in duty bound to save this circle. He, and no one else. If he does not save it, he cannot be saved. These are the labors each man is given and is in duty bound to complete before he dies. He may not otherwise be saved. For his own soul is scattered and enslaved in these things about him, in trees, in animals, in men, in ideas, and it is his own soul he saves by completing these labors.

It is the way of the superior man to prefer the concealment of his virtue, while it daily becomes more illustrious, and it is the way of the mean man to seek notoriety, while he daily goes more and more to ruin. It is characteristic of the superior man, appearing insipid, yet never to produce satiety; while showing a simple negligence, yet to have his accomplishments recognized; while seemingly plain, yet to be discriminating. He knows how what is distant lies in what is near. He knows where the wind proceeds from. He knows how what is minute becomes manifested. Such a one, we may be sure, will enter into virtue.

I would say that teleology is theology, and that God is not a "because," but rather an "in order to."

Of escape there are but three methods - two chimerical and a third real. The first two are the dram-shop and the church, debauchery of the body or debauchery of the mind; the third is social revolution.

I am convinced we do not only love ourselves in others but hate ourselves in others too.

Real culture lives by sympathies and admirations, not by dislikes and disdain - under all misleading wrappings it pounces unerringly upon the human core.

The images of mankind have become the most basic thing about them. And they're all software, and disembodied.

A true prayer and religious reconciling of ourselves to Almighty God cannot enter into an impure soul, subject at the very time to the dominion of Satan. He who calls God to his assistance whilst in a course of vice, does as if a cut-purse should call a magistrate to help him, or like those who introduce the name of God to the attestation of a lie.

We look at the present through a rear-view mirror. We march backwards into the future.

A witty statesman said, you might prove anything by figures.

When one admits that nothing is certain one must, I think, also admit that some things are much more nearly certain than others. It is much more nearly certain that we are assembled here tonight than it is that this or that political party is in the right. Certainly there are degrees of certainty, and one should be very careful to emphasize that fact, because otherwise one is landed in an utter skepticism, and complete skepticism would, of course, be totally barren and completely useless.

Small creatures die because larger creatures are hungry. How superior to this human confusion of greed and creed, blood and fire.

To say that all philosophy is writing is, minimally, to say that it is never the transparent expression of thought.

Life, individual or collective, personal or historic, is the one entity in the universe whose substance is compact of danger, of adventure. It is, in the strict sense of the word, drama. ... The primary, radical meaning of life appears when it is employed in the sense not of biology, but of biography. For the very strong reason that the whole of biology is quite definitely only a chapter in certain biographies, it is what biologists do in the portion of their lives open to biography.

For legislators make the citizens good by forming habits in them, and this is the wish of every legislator, and those who do not effect it miss their mark, and it is in this that a good constitution differs from a bad one.

The history of the American kings of capital and authority is the history of repeated crimes, injustice, oppression, outrage, and abuse, all aiming at the suppression of individual liberties and the exploitation of the people. A vast country, rich enough to supply all her children with all possible comforts, and insure well-being to all, is in the hands of a few, while the nameless millions are at the mercy of ruthless wealth gatherers, unscrupulous lawmakers, and corrupt politicians.The reign of these kings is holding mankind in slavery, perpetuating poverty and disease, maintaining crime and corruption; it is fettering the spirit of liberty, throttling the voice of justice, and degrading and oppressing humanity. It is engaged in continual war and slaughter, devastating the country and destroying the best and finest qualities of man; it nurtures superstition and ignorance, sows prejudice and strife, and turns the human family into a camp of Ishmaelites.

So far as living instruments of labour are concerned, for instance horses, their reproduction is timed by nature itself. Their average lifetime as instruments of labour is determined by the laws of nature. As soon as this term has expired they must be replaced by new ones. A horse cannot be replaced piecemeal; it must be replaced by another horse.

It is very likely that there are many, many planets carrying life, even intelligent life, throughout the universe, because there are so many stars. By sheer chance, even if those chances are small, a great many life forms and a great many intelligences may exist.

The proximity between the counterfeit and the good coin does not make the good coin counterfeit nor the counterfeit good. In the same way the proximity between truth and falsehood does not make truth falsehood nor falsehood truth.

One could count on one's fingers the number of scientists in the entire world who have a general idea of the history and development of their own particular science; there is not one who is really competent as regards sciences other than his own. As science forms an indivisible whole, one may say that there are no longer, strictly speaking, any scientists, but only drudges doing scientific work. . . .

The power of the periodical press is second only to that of the people.

If you would convince a man that he does wrong, do right. But do not care to convince him. Men will believe what they see.

Rules necessary for axioms. Not to demand in axioms any but things perfectly evident.

Whensoever hostile aggressions...require a resort to war, we must meet our duty and convince the world that we are just friends and brave enemies.

My friend Professor Tolkien asked me the very simple question, "What class of men would you expect to be most preoccupied with, and most hostile to, the idea of escape?" and gave the obvious answer: jailers.

No pleasure is in itself evil, but the things which produce certain pleasures entail annoyances many times greater than the pleasures themselves.

Negative-utilitarianism is only one particular denomination of a broad church to which the reader may well in any case not subscribe. Fortunately, the program can be defended on grounds that utilitarians of all stripes can agree on. So a defence will be mounted against critics of the theory and application of a utilitarian ethic in general. For in practice the most potent and effective means of curing unpleasantness is to ensure that a defining aspect of future states of mind is their permeation with the molecular chemistry of ecstasy: both genetically precoded and pharmacologically fine-tuned. Orthodox utilitarians will doubtless find the cornucopian abundance of bliss this strategy delivers is itself an extra source of moral value. Future generations of native ecstatics are unlikely to disagree.

Instead of enabling humans to improve their lot, science degrades the natural environment in which humans must live. Instead of enabling death to be overcome, it produces ever more powerful technologies of mass destruction. None of this is the fault of science; what it shows is that science is not sorcery. The growth of knowledge enlarges what humans can do. It cannot reprieve them from being what they are.

Now the mass of mankind are plainly... choosing a life like that of brute animals...

I think all the great religions of the world - Buddhism, Hinduism, Christianity, Islam, and Communism - both untrue and harmful. It is evident as a matter of logic that, since they disagree, not more than one of them can be true. With very few exception, the religions which a man accepts is that of the community in which he lives, which makes it obvious that the influence of environment is what has led him to accept the religion in question.

Dialogue never ends not for lack of time or opportunity but for essential reasons.

The fact is he made a prodigious blunder in commencing the attack, and now his only chance is to be silent and let people forget the exposure. I do not believe that in the whole history of science there is a case of any man of reputation getting himself into such a contemptible position.

People praise virtue, but they hate it, they run away from it. It freezes you to death, and in this world you've got to keep your feet warm.

Invention is the mother of all necessities.

The other big issue is an emotional one. We tend to feel the greatest bonds of solidarity with people that are close to us. There are very few true citizens of the world. We're citizens of individual countries and we really feel the closest bonds to people that live within our nation, and therefore... the nation becomes a kind of social glue. But if you're going to make a national identity compatible with liberalism, it has to be the right kind of national identity. It has to be one that is open to all of the citizens that actually live in the territory of the nation. It can't exclude certain groups by race, by ethnicity, by religious belief and the like, and therefore it needs to be an open identity that is based on essentially liberal ideas.

History is nothing but assisted and recorded memory. It might almost be said to be no science at all, if memory and faith in memory were not what science necessarily rest on. In order to sift evidence we must rely on some witness, and we must trust experience before we proceed to expand it. The line between what is known scientifically and what has to be assumed in order to support knowledge is impossible to draw. Memory itself is an internal rumour; and when to this hearsay within the mind we add the falsified echoes that reach us from others, we have but a shifting and unseizable basis to build upon. The picture we frame of the past changes continually and grows every day less similar to the original experience which it purports to describe.

Self-respect will keep a man from being abject when he is in the power of enemies, and will enable him to feel that he may be in the right when the world is against him.

Heroes abound at the dawn of civilizations, during pre-Homeric and Gothic epochs, when people, not having yet experienced spiritual torture, satisfy their thirst for renunciation through a derivative: heroism.

If it is not right, do not do it, if it is not true, do not say it. For let thy efforts be -

Apart from any other basis which might justify a superiority, education, as a power, raised him who possessed it over the weak, who lacked it, and the educated man counted in his circle, however large or small it was, as the mighty, the powerful, the imposing one: for he was an authority.
