But by far the greatest obstacle to the progress of science and to the undertaking of new tasks and provinces therein is found in this - that men despair and think things impossible.

No one has yet been found so firm of mind and purpose as resolutely to compel himself to sweep away all theories and common notions, and to apply the understanding, thus made fair and even, to a fresh examination of particulars. Thus it happens that human knowledge, as we have it, is a mere medley and ill-digested mass, made up of much credulity and much accident, and also of the childish notions which we at first imbibed.

The brain may be regarded as a kind of parasite of the organism, a pensioner, as it were, who dwells with the body.

He was seized and dragged off to King Philip, and being asked who he was, replied, "A spy upon your insatiable greed."

A company of solemn tyrants is impervious to all seductions.

The new media are not bridges between man and nature - they are nature...The new media are not ways of relating us to the old world; they are the real world and they reshape what remains of the old world at will.

All names of God remain hallowed because they have been used not only to speak of God but also to speak to him.

None but a Craftsman can judge of a craft.

When one says, for example, that superiority and inferiority is a formation to be found in every human association, though the proposition certainly involves very profound insight into the essence of human nature and human relationship, yet the assertion is so general that it affords little knowledge of particular societary formations. In order to reach such particular knowledge we must study separate types of superiority and inferiority, and we must master the special features of their formation, which in proportion to their definiteness of course lose generality of application.

Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. This is the first and great commandment. And the second is like unto it, Thou shalt love thy neighbour as thyself. On these two commandments hang all the law and the prophets.

It is difficult for the isolated individual to work himself out of the immaturity which has become almost natural for him. He has even become fond of it and for the time being is incapable of employing his own intelligence, because he has never been allowed to make the attempt. Statutes and formulas, these mechanical tools of a serviceable use, or rather misuse, of his natural faculties, are the ankle-chains of a continuous immaturity. Whoever threw it off would make an uncertain jump over the smallest trench because he is not accustomed to such free movement. Therefore there are only a few who have pursued a firm path and have succeeded in escaping from immaturity by their own cultivation of the mind.

...what I look to with seriousness is the Phalanx of Party which exists in the body of the dissenters, who are, at the very least, nine tenths of them entirely devoted, some with greater some with less zeal, to the principles of the French Revolution.

We're terrible animals. I think that the Earth's immune system is trying to get rid of us, as well it should.

The Christian priesthood, finding the doctrines of Christ levelled to every understanding, and too plain to need explanation, saw in the mysticism of Plato, materials with which they might build up an artificial system, which might, from its indistinctness, admit everlasting controversy, give employment for their order, and introduce it to profit, power and pre-eminence. The doctrines which flowed from the lips of Jesus himself are within the comprehension of a child ; but thousands of volumes have not yet explained the Platonisms engrafted on them; and for this obvious reason, that nonsense can never be explained.

The essential nature (concerning the soul) cannot be corporeal, yet it is also clear that this soul is present in a particular bodily part, and this one of the parts having control over the rest (heart).

The highest perfection of human life consists in the mind of man being detached from care, for the sake of God.

When governments fear the people, there is liberty. When the people fear the government, there is tyranny.

It seems to be almost an invariable rule that as real power declines, the symbols of power multiply and intensify in compensation.

The usage of the words "public" and "public sphere" betrays a multiplicity of concurrent meanings. Their origins go back to various historical phases and, when applied synchronically to the conditions of a bourgeois society that is industrially advanced and constituted as a social-welfare state, they fuse into a clouded amalgam. Yet the very conditions that make the inherited language seem inappropriate appear to require these words, however confused their employment.

I'm delighted to hear someone make the claim that there is moral progress because it can be such a incendiary thing to say, and its something that I say and deeply believe in.

However hard they try, men cannot create a social organism, they can only create an organization. In the process of trying to create an organism they will merely create a totalitarian despotism.

He who intends to enjoy life should not be busy about many things, and in what he does should not undertake what exceeds his natural capacity. On the contrary, he should have himself so in hand that even when fortune comes his way, and is apparently ready to lead him on to higher things, he should put her aside and not o'erreach his powers. For a being of moderate size is safer than one that bulks too big.

The distance between oneself and other persons and other species can fall anywhere on a continuum. Even for other persons the understanding of what it is like to be them is only partial, and when one moves to species very different from oneself, a lesser degree of partial understanding may still be available. The imagination is remarkably flexible. My point, however, is not that we cannot know what it is like to be a bat. I am not raising that epistemological problem. My point is rather that even to form a conception of what it is like to be a bat and a fortiori to know what it is like to be a bat, one must take up the bat's point of view.

When technology extends one of our senses, a new translation of culture occurs as swiftly as the new technology is interiorized.

One reason why mathematics enjoys special esteem, above all other sciences, is that its laws are absolutely certain and indisputable, while those of other sciences are to some extent debatable and in constant danger of being overthrown by newly discovered facts.

Bishop Berkeley destroyed this world in one volume octavo; and nothing remained after his time, but mind - which experienced a similar fate from the hand of Mr. Hume, in 1737.

If it is my interest to have a farm, it is my interest to take it away from my neighbour; if it is my interest to have a cloak, it is my interest also to steal it from a bath. This is the source of wars, seditions, tyrannies, plots.

It cannot be doubted, I think, that Mr. Darwin has satisfactorily proved that what he terms selection, or selective modification, must occur, and does occur, in nature; and he has also proved to superfluity that such selection is competent to produce forms as distinct, structurally, as some genera even are. If the animated world presented us with none but structural differences, I should have no hesitation in saying that Mr. Darwin has demonstrated the existence of a true physical cause, amply competent to account for the origin of living species, and of man among the rest.

Children have as much mind to shew that they are free, that their own good actions come from themselves, that they are absolute and independent, as any of the proudest of you grown men, think of them as you please.

I do not understand! I understand nothing! I cannot understand nor do I want to understand! I want to believe! To Believe!

The political freedom of conscience and of the press, so far from being as it is commonly supposed an extension, is a new case of the limitation of rights and discretion. Conscience and the press ought to be unrestrained, not because men have a right to deviate from the exact line that duty prescribes, but because society, the aggregate of individuals, has no right to assume the prerogative of an infallible judge, and to undertake authoritatively to prescribe to its members in matters of pure speculation.

Nothing is more indispensable to true religiosity than a mediator that links us with divinity.

The most obvious division of society is into rich and poor; and it is no less obvious, that the number of the former bear a great disproportion to those of the latter. The whole business of the poor is to administer to the idleness, folly, and luxury of the rich; and that of the rich, in return, is to find the best methods of confirming the slavery and increasing the burdens of the poor. In a state of nature, it is an invariable law, that a man's acquisitions are in proportion to his labours. In a state of artificial society, it is a law as constant and as invariable, that those who labour most enjoy the fewest things; and that those who labour not at all have the greatest number of enjoyments. A constitution of things this, strange and ridiculous beyond expression! We scarce believe a thing when we are told it, which we actually see before our eyes every day without being in the least surprised.

Should it be proved that woman is naturally weaker than man, from whence does it follow that it is natural for her to labour to become still weaker than nature intended her to be? Arguments of this cast are an insult to common sense, and savour of passion. The divine right of husbands, like the divine right of kings, may, it is to be hoped, in this enlightened age, be contested without danger, and though conviction may not silence many boisterous disputants, yet, when any prevailing prejudice is attacked, the wise will consider, and leave the narrow-minded to rail with thoughtless vehemence at innovation.

Science is the knowledge of Consequences, and dependence of one fact upon another: by which, out of that we can presently do, we know how to do something else when we will, or the like, another time.

It is then unnecessary to investigate whether there be beyond the heaven Space, Void or Time. For there is a single general space, a single vast immensity which we may freely call Void; in it are innumerable globes like this one on which we live and grow. This space we declare to be infinite, since neither reason, convenience, possibility, sense-perception nor nature assign to it a limit. In it are an infinity of worlds of the same kind as our own.

How many women does one need to sing the scale of love all the way up and down?

It is the business of the future to be dangerous; and it is among the merits of science that it equips the future for its duties.

We Jews have been too adaptable. We have been too eager to sacrifice our idiosyncrasies for the sake of social conformity. ... Even in modern civilization, the Jew is most happy if he remains a Jew.

In all sectors of society there should be roughly equal prospects of culture and achievement for everyone similarly motivated and endowed. The expectations of those with the same abilities and aspirations should not be affected by their social class.

No man can have a peaceful life who thinks too much about lengthening it.

The workmen's revolution, with the terrors of destruction and murder, not only threatens us, but we have already been living upon its verge during the last thirty years, and it is only by various cunning devices that we have been postponing the crisis... The hatred and contempt of the oppressed people are increasing, and the physical and moral strength of the richer classes are decreasing: the deceit which supports all this is wearing out, and the rich classes have nothing wherewith to comfort themselves.

The best and greatest winning is a true friend; and the greatest loss is the loss of time.

Those who have ever valued liberty for its own sake believed that to be free to choose, and not to be chosen for, is an inalienable ingredient in what makes human beings human.

A free man thinks of death least of all things; and his wisdom is a meditation not of death but of life.

The sins of the flesh are bad, but they are the least bad of all sins. All the worst pleasures are purely spiritual: the pleasure of putting other people in the wrong, of bossing and patronising and spoiling sport, and back-biting; the pleasures of power, of hatred. For there are two things inside me, competing with the human self which I must try to become. They are the Animal self, and the Diabolical self. The Diabolical self is the worse of the two. That is why a cold, self-righteous prig who goes regularly to church may be far nearer to hell than a prostitute. But, of course, it is better to be neither.
