A logical theory may be tested by its capacity for dealing with puzzles, and it is a wholesome plan, in thinking about logic, to stock the mind with as many puzzles as possible, since these serve much the same purpose as is served by experiments in physical science.

To doubt everything or to believe everything are two equally convenient solutions; both dispense with the necessity of reflection.

A bad feeling is a commotion of the mind repugnant to reason, and against nature.

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.

He is dead, and my hatred has died with him.

While it is in no way racist for any author to write a book exclusively about white women, it is fundamentally racist for books to be published that focus solely on the American white woman's experience in which that experience is assumed to be the American woman's experience.

You [a disciple], shall I teach you about knowledge? What you know, you know, what you don't know, you don't know. This is true knowledge.

You could send your soul after the good you had expected, instead of turning it to the good you had got. You could refuse the real good; you could make the real fruit taste insipid by thinking of the other.

All of those who are "without" - without employment, without residence, without housing - are really excluded only in part.

Whatever can happen at any time can happen today.

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.

By all evidence we are in the world to do nothing.

It really is worth the trouble to invent a new symbol if we can thus remove not a few logical difficulties and ensure the rigour of the proofs. But many mathematicians seem to have so little feeling for logical purity and accuracy that they will use a word to mean three or four different things, sooner than make the frightful decision to invent a new word.

To expect, indeed, that the freedom of trade should ever be entirely restored in Great Britain, is as absurd as to expect that an Oceana or Utopia should never be established in it.

Consciousness must essentially cover an interval of time; for if it did not, we could gain no knowledge of time, and not merely no veracious cognition of it, but no conception whatever. We are therefore, forced to say that we are immediately conscious through an infinitesimal interval of time.

A person who is transformed by the instructions of a teacher, devotes himself to study, and abides by ritual and rightness may become a noble person, while one who follows his nature and emotions, is content to give free play to his passions, and abandons ritual and rightness is a lesser person.

We cannot suppose that an individual's thinking survives bodily death, since that destroys the organization of the brain and dissipates the energy which utilized the brain tracks. God and immortality, the central dogma of the Christian religion, find no support in science. But we in the West have come to think of them as the irreducible minimum of theology. No doubt people will continue to entertain these beliefs, because they are pleasant, just as it is pleasant to think ourselves virtuous and our enemies wicked. But for my part I cannot see any grounds for either. I do not pretend to be able to prove that there is no God. I equally cannot prove Satan is a fiction. The Christian God may exist, so might the Gods of Olympus, Ancient Egypt or Babylon; but no one of these hypotheses is more probable than any other. They lie outside the region of provable knowledge and there is no reason to consider any of them.

Of all the cultural aspects of humanity, the only one which is not broken up into national or regional splinters is science. Different nations have different languages, they may have different religions, may have different dietaries, may have different holidays, different ways of thinking, but here's only one science. 

There are people with whom everything they consider a means turns mysteriously into an end.

Disturbances in society are never more fearful than when those who are stirring up the trouble can use the pretext of religion to mask their true designs.

Many Britons...feel strongly about something which was once called "the alien wedge". And surely it cannot be doubted, even by those who profess allegiance to the "multicultural society", that our society, unlike America, is not of that kind, and therefore that immigration cannot be an object of merely passive contemplation on the part of the present citizenship. There is perhaps no greater sign of the strength of liberalism (a strength which issues, not from popular consensus, but from the political power of the liberal elite) than that it has made it impossible for any but the circumlocutory to argue that the English, the Scots and the Welsh have a prior claim to the benefits of the civilization that their ancestors created, which entitles them to reserve its benefits for themselves.

I think no virtue goes with size; The reason of all cowardice Is, that men are overgrown, And, to be valiant, must come down To the titmouse dimension.

The measure of a man is a man. Justice, morality, ethics, fairness, goodness all based on the preservation of life. You can do other things, but you'd be Good by coincidence.

Man is a creature who lives not upon bread alone, but principally by catchwords; and the little rift between the sexes is astonishingly widened by simply teaching one set of catchwords to the girls and another to the boys.

This "knowing what to do"... is a matter of having the right purpose, the purpose appropriate to the situation in hand... The one who "knows what to do" is the one on whom you can rely to make the best shot at success, whenever success is possible.

The people reign over the American political world as God rules over the universe. It is the cause and the end of all things; everything rises out of it and is absorbed back into it.

All nature abounds in proofs of other influences than merely mechanical action, even in the physical world. They crowd in upon us at the rate of several every minute. And my observation of men has led me to this little generalization. Speaking only of men who really think for themselves and not of mere reporters, I have not found that it is the men whose lives are mostly passed within the four walls of a physical laboratory who are most inclined to be satisfied with a purely mechanical metaphysics. On the contrary, the more clearly they understand how physical forces work the more incredible it seems to them that such action should explain what happens out of doors. A larger proportion of materialists and agnostics is to be found among the thinking physiologists and other naturalists, and the largest proportion of all among those who derive their ideas of physical science from reading popular books.

But how can the characters in a play guess the plot? We are not the playwright, we are not the producer, we are not even the audience. We are on the stage. To play well the scenes in which we are "on" concerns us much more than to guess about the scenes that follow it.

A prudent man should always follow in the path trodden by great men and imitate those who are most excellent.

Death poses a problem which replaces all the others. What is deadly to philosophy, to the naive belief in the hierarchy of perplexities.

Cato requested old men not to add the disgrace of wickedness to old age, which was accompanied with many other evils.

In its mad passion for power, the Communist State even sought to strengthen and deepen the very ideas and conceptions which the Revolution had come to destroy. It supported and encouraged all the worst antisocial qualities and systematically destroyed the already awakened conception of the new revolutionary values.The sense of justice and equality, the love of liberty and of human brotherhood - these fundamentals of the real regeneration of society - the Communist State suppressed to the point of extermination. Man's instinctive sense of equity was branded as weak sentimentality; human dignity and liberty became a bourgeois superstition; the sanctity of life, which is the very essence of social reconstruction, was condemned as unrevolutionary, almost counter-revolutionary. This fearful perversion of fundamental values bore within itself the seed of destruction.

Friendship is almost always the union of a part of one mind with the part of another; people are friends in spots.

One never goes so far as when one doesn't know where one is going.

What the public wants is the image of passion, not passion itself.

Ideal legislators do not vote their interests.

Some say that the body is the "tomb" of the soul, their notion being that the soul is buried in the present life; and again, because by its means the soul gives any signs which it gives, it is for this reason also properly called "sign". But I think it most likely that the Orphic poets gave this name, with the idea that the soul is undergoing punishment for something; they think it has the body as an enclosure to keep it safe, like a prison, and this is, as the name itself denotes, the "safe" for the soul, until the penalty is paid, and not even a letter needs to be changed.

The new education must consist essentially in this, that it completely destroys freedom of will in the soil which it undertakes to cultivate, and produces on the contrary strict necessity in the decisions of the will, the opposite being impossible. Such a will can henceforth be relied on with confidence and certainty.

The prospect for the human race is sombre beyond all precedent. Mankind are faced with a clear-cut alternative: either we shall all perish, or we shall have to acquire some slight degree of common sense. A great deal of new political thinking will be necessary if utter disaster is to be averted.

It is an unsufferable blasphemy to reject the public ministry or to say that people can become holy without sermons and Church. This involves a destruction of the Church and rebellion against ecclesiastical order; such upheavals must be warded off and punished like all other revolts.

The trade of governing has always been monopolized by the most ignorant and the most rascally individuals of mankind.

And now the sagacious reader, who is capable of reading into these lines what does not stand written in them, but is nevertheless implied, will be able to form some conception of the serious feelings with which I then set foot in Emmendingen.

When you read God's Word, in everything you read, continually to say to yourself: It is I to whom it is speaking - this is earnestness, precisely this is earnestness. Not a single one of those to whom the cause of Christianity in the higher sense has been entrusted forgot to urge this again and again as most crucial, as unconditionally the condition if you are to come to see yourself in the mirror.
