The true line is not between "hard" natural science and "soft" social sciences, but between precise science limited to highly abstract and simple phenomena in the laboratory and inexact science and technology dealing with complex problems in the real world.

So we are always esthetically disappointed when the sensuous qualities and the intellectual properties of an object do not coalesce.

In vain, therefore, should we pretend to determine any single event, or infer any cause or effect, without the assistance of observation and experience.

Feminism in the United States has never emerged from the women who are most victimized by sexist oppression; women who are daily beaten down, mentally, physically, and spiritually-women who are powerless to change their condition in life. They are a silent majority. A mark of their victimization is that they accept their lot in life without visible question, without organized protest, without collective anger or rage.

The truth can be spoken only by someone who is already at home in it; not by someone who still lives in untruthfulness, and does no more than reach out towards it from within untruthfulness.

We have the right to conclude from this that syndicalist violence, perpetrated in the course of strikes by proletarians who desire the overthrow of the State, must not be confused with the acts of savagery which the superstition of the State suggested to the revolutionaries of 1793, when they had power in their hands and were able to oppress the conquered - following the principles which they had received from the Church and from the monarchy.

It is better to lose health like a spendthrift than to waste it like a miser. It is better to live and be done with it, than to die daily in the sick-room.

Scientists believe there is a hierarchy of facts and that among them may be made a judicious choice. They are right, since otherwise there would be no science... One need only open the eyes to see that the conquests of industry which have enriched so many practical men would never have seen the light, if these practical men alone had existed and if they had not been preceded by unselfish devotees who died poor, who never thought of utility, and yet had a guide far other than caprice.As Mach says, these devotees have spared their successors the trouble of thinking.

Consciousness is much more than the thorn, it is the dagger in the flesh.

England, it is true, in causing a social revolution in Hindostan, was actuated only by the vilest interests, and was stupid in her manner of enforcing them. But that is not the question. The question is, can mankind fulfil its destiny without a fundamental revolution in the social state of Asia? If not, whatever may have been the crimes of England she was the unconscious tool of history in bringing about that revolution.

Our own experience provides the basic material for our imagination, whose range is therefore limited. It will not help to try to imagine that one has webbing on one's arms, which enables one to fly around at dusk and dawn catching insects in one's mouth; that one has very poor vision, and perceives the surrounding world by a system of reflected high-frequency sound signals; and that one spends the day hanging upside down by one's feet in an attic. Insofar as I can imagine this (which is not very far), it tells me only what it would be like for me to behave as a bat behaves. But that is not the question. I want to know what it is like for a bat to be a bat. Yet if I try to imagine this, I am restricted to the resources of my own mind, and those resources are inadequate to the task.

Nothing made a happy slave, but a degraded man. In proportion as the mind grew callous to its degradation, and all sense of manly pride was lost, the slave felt comfort. In fact, he was no longer a man. If he were to define a man, he would say with Shakspeare,"Man is a being, holding large discourse,Looking before and after."A slave was incapable of either looking before or after.

Since it is always the same person whose mind thinks, wills, and judges, the autonomous nature of these activities has created great difficulties. Reason's inability to move the will, plus the fact that thinking can only "understand" what is past what neither remove it nor "rejuvenate it" ... have led to the various doctrines asserting the mind's impotence and the force of the irrational, in brief to Hume's famous dictum that "Reason is and ought only to be the slave of the passions," that is, to a rather simple-minded reversal of the Platonic notion of reason's uncontested rulership in the household of the soul. What is so remarkable in all these theories and doctrines is their implicit monism, the claim that behind the obvious multiplicity of the world's appearances and, even more pertinently to our context, behind the obvious plurality of man's faculties and abilities, there must exist a oneness - the old hen pan, "the all is one" - either a single source or a single ruler.

Mahomet himself, after all that can be said about him, was not a sensual man. We shall err widely if we consider this man as a common voluptuary, intent mainly on base enjoyments, - nay on enjoyments of any kind. His household was of the frugalest; his common diet barley-bread and water: sometimes for months there was not a fire once lighted on his hearth. They record with just pride that he would mend his own shoes, patch his own cloak. A poor, hard-toiling, ill-provided man; careless of what vulgar men toil for.

My main theme is the extension of the nervous system in the electric age, and thus, the complete break with five thousand years of mechanical technology. This I state over and over again. I do not say whether it is a good or bad thing. To do so would be meaningless and arrogant.

Deem not life a thing of consequence. For look at the yawning void of the future, and at that other limitless space, the past.

There are Plebes in all classes.

A real reconciliation of East and West is impossible and inconceivable on the basis of a materialistic Communism, or of a materialistic Capitalism, or indeed of a materialistic Socialism. The third way will neither be "anti-Communist" nor "anti-Capitalist". It will recognize the truth in liberal democracy, and it will equally recognize the truth in Communism. A critique of Communism and Marxism does not entail an enmity towards Soviet Russia, just as a critique of liberal democracy is not entail enmity towards the west. ... But the final and most important justification of a "third way" is that there must be a place from which we may boldly testify to, and proclaim, truth, love and justice. No one today likes truth: utility and self interest have long ago been substituted for truth.

Take away your opinion, and there is taken away the complaint. Take away the complaint, and the hurt is gone.

A noble person attracts noble people, and knows how to hold on to them.

Retire into thyself. The rational principle which rules has this nature, that it is content with itself when it does what is just, and so secures tranquility.

Wherever one finds oneself inclined to bitterness, it is a sign of emotional failure: a larger heart, and a greater self-restraint, would put a calm autumnal sadness in the place of the instinctive outcry of pain.

'When two equal weights are supported on the middle point between them, the pressure on the fulcrum is equal to the sum of the weights.'

Like strawberry wives, that laid two or three great strawberries at the mouth of their pot, and all the rest were little ones.

After World War II, liberal rights were not something that were only deserved by white Europeans. ...There was a recognition that the black and brown peoples being held in colonial bondage could not consistently be held in that bondage, because liberalism was a universal doctrine. ...That's the other respect in which we can defend liberalism, a moral one.

Mathematics have a triple aim. They must furnish an instrument for the study of nature. But that is not all: they have a philosophic aim and, I dare maintain, an esthetic aim. They must aid the philosopher to fathom the notions of number, of space, of time. And above all, their adepts find therein delights analogous to those given by painting and music. They admire the delicate harmony of numbers and forms; they marvel when a new discovery opens to them an unexpected perspective; and has not the joy they thus feel the esthetic character, even though the senses take no part therein? Only a privileged few are called to enjoy it fully, it is true, but is not this the case for all the noblest arts?This is why I do not hesitate to say that mathematics deserve to be cultivated for their own sake, and the theories inapplicable to physics as well as the others. Even if the physical aim and the esthetic aim were not united, we ought not to sacrifice either.

The mathematician is born, not made.

I saw the Emperor-this world-soul-riding out of the city on reconnaissance. It is indeed a wonderful sensation to see such an individual, who, concentrated here at a single point, astride a horse, reaches out over the world and masters it.

There is no one at the Communion table who retains against you even the least of your sins, no one, unless you yourself do it. So cast them away from yourself, and the recollection of them, lest in it your retain them; and cast the recollection of your having cast your sins away, lest in it you retain them.

Intelligence is quickness to apprehend as distinct from ability, which is capacity to act wisely on the thing apprehended.

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

The concept of positivity in itself, in abstracto, has become part and parcel of the ideology today. ... Critique has started to become suspect, regardless of its content.

I see myself immersed in the depths of human existence and standing in the face of the ineffable mystery of the world and of all that is. And in that situation, I am made poignantly and burningly aware that the world cannot be self-sufficient, that there is hidden in some still greater depth a mysterious, transcendent meaning. This meaning is called God. Men have not been able to find a loftier name, although they have abused it to the extent of making it almost unutterable. God can be denied only on the surface; but he cannot be denied where human experience reaches down beneath the surface of flat, vapid, commonplace existence.

The Presbyterian clergy are loudest, the most intolerant of all sects, the most tyrannical, and ambitious; ready at the word of the lawgiver, if such a word could be now obtained, to put the torch to the pile, and to rekindle in this virgin hemisphere, the flames in which their oracle Calvin consumed the poor Servetus, because he could not find in his Euclid the proposition which has demonstrated that three are one, and one is three, nor subscribe to that of Calvin that magistrates have a right to exterminate all heretics to Calvinistic creed.

There is in our souls some native seed of reason, which, if nourished by good counsel and training, flowers into virtue, but which, on the other hand, if unable to resist the vices surrounding it, is stifled and blighted.

Luxury is the opposite of the naturally necessary.

The meaning of relativity has been widely misunderstood. Philosophers play with the word, like a child with a doll. Relativity, as I see it, merely denotes that certain physical and mechanical facts, which have been regarded as positive and permanent, are relative with regard to certain other facts in the sphere of physics and mechanics. It does not mean that everything in life is relative and that we have the right to turn the whole world mischievously topsy-turvy.

There is no need for you to develop an armed insurrection. Christ himself has already begun an insurrection with his mouth.

The human understanding is moved by those things most which strike and enter the mind simultaneously and suddenly, and so fill the imagination; and then it feigns and supposes all other things to be somehow, though it cannot see how, similar to those few things by which it is surrounded.

We rarely hear, it has been said, of the combinations of masters, though frequently of those of the workman. But whoever imagines, upon this account, that masters rarely combine, is as ignorant of the world as of the subject.

We can hope that the ways of peace will attract the Arabic nations, for their territory and opportunities are broad enough for immeasurable advance, if the energies vented in spleen, are turned instead to a modernisation of the technology, a restoration of the soil, and a renovation of the economic, social, and political structure of those great and venerable lands.

As the animus is partial to argument, he can best be seen at work in disputes where both parties know they are right. Men can argue in a very womanish way, too, when they are anima-possessed and have thus been transformed into the animus of their own anima.

Before you embark on a journey of revenge, dig two graves.
