If I were a medical man, I should prescribe a holiday to any patient who considered his work important.

Most people would rather die than think; in fact, they do so.
I am delighted to know that Principia Mathematica can now be done by machinery... I am quite willing to believe that anything in deductive logic can be done by machinery.
So far as I can remember, there is not one word in the Gospels in praise of intelligence.
The doctrine, as I understand it, consists in maintaining that the language of daily life, with words used in their ordinary meanings, suffices for philosophy, which has no need of technical terms or of changes in the significance of common terms. I find myself totally unable to accept this view. I object to it: 1.Because it is insincere; 2.Because it is capable of excusing ignorance of mathematics, physics and neurology in those who have had only a classical education; 3.Because it is advanced by some in a tone of unctuous rectitude, as if opposition to it were a sin against democracy; 4.Because it makes philosophy trivial; 5.Because it makes almost inevitable the perpetuation amongst philosophers of the muddle-headedness they have taken over from common sense.
In a society safe and worthy to be free, teaching which produces a willingness to lead, as well as a willingness to follow, must be given to all.
To expect a personality to survive the disintegration of the brain is like expecting a cricket club to survive when all of its members are dead.
With equal passion I have sought knowledge. I have wished to understand the hearts of men. I have wished to know why the stars shine. And I have tried to apprehend the Pythagorean power by which number holds sway about the flux. A little of this, but not much, I have achieved.
William James describes a man who got the experience from laughing-gas; whenever he was under its influence, he knew the secret of the universe, but when he came to, he had forgotten it. At last, with immense effort, he wrote down the secret before the vision had faded. When completely recovered, he rushed to see what he had written. It was 'A smell of petroleum prevails throughout'.

Real life is, to most men, a long second-best, a perpetual compromise between the ideal and the possible; but the world of pure reason knows no compromise, no practical limitations, no barrier to the creative activity.
In all affairs it's a healthy thing now and then to hang a question mark on the things you have long taken for granted.
A sense of duty is useful in work but offensive in personal relations. Certain characteristics of the subject are clear. To begin with, we do not, in this subject, deal with particular things or particular properties: we deal formally with what can be said about 'any' thing or 'any' property. We are prepared to say that one and one are two, but not that Socrates and Plato are two, because, in our capacity of logicians or pure mathematicians, we have never heard of Socrates or Plato. A world in which there were no such individuals would still be a world in which one and one are two. It is not open to us, as pure mathematicians or logicians, to mention anything at all, because, if we do so we introduce something irrelevant and not formal.
A proverb is one man's wit and all men's wisdom.
The greatest challenge to any thinker is stating the problem in a way that will allow a solution.

The point of philosophy is to start with something so simple as not to seem worth stating, and to end with something so paradoxical that no one will believe it.
In the first place a philosophical proposition must be general. It must not deal specially with things on the surface of the earth, or within the solar system, or with any other portion of space and time.... This brings us to a second characteristic of philosophical propositions, namely that they must be a priori. A philosophical proposition must be such as can neither be proved nor disproved by empirical evidence.... Philosophy, if what has been said is correct, becomes indistinguishable from logic as that word has now come to be used.
Patriotism is the willingness to kill and be killed for trivial reasons.
Indemnity for the past and security for the future.
Three passions, simple but overwhelmingly strong, have governed my life: the longing for love, the search for knowledge, and unbearable pity for the suffering of mankind.
Ordinary language is totally unsuited for expressing what physics really asserts, since the words of everyday life are not sufficiently abstract. Only mathematics and mathematical logic can say as little as the physicist means to say.
There is no nonsense so arrant that it cannot be made the creed of the vast majority by adequate government action.
The study of logic becomes the central study in philosophy: it gives the method of research in philosophy, just as mathematics gives the method in physics.... All this supposed knowledge in the traditional systems must be swept away, and a new beginning m
It is preoccupation with possessions, more than anything else, that prevents us from living freely and nobly.
It seems clear that there must be some way of defining logic otherwise than in relation to a particular logical language. The fundamental characteristic of logic, obviously, is that which is indicated when we say that logical propositions are true in virt

If your experiment needs statistics, you ought to have done a better experiment.
It can be shown that a mathematical web of some kind can be woven about any universe containing several objects. The fact that our universe lends itself to mathematical treatment is not a fact of any great philosophical significance.
'But,' you might say, 'none of this shakes my belief that 2 and 2 are 4.' You are quite right, except in marginal cases and it is only in marginal cases that you are doubtful whether a certain animal is a dog or a certain length is less than a meter. Tw
I wanted certainty in the kind of way in which people want religious faith. I thought that certainty is more likely to be found in mathematics than elsewhere. But I discovered that many mathematical demonstrations, which my teachers expected me to accept,

If I had the power to organize higher education as I should wish it to be, I should seek to substitute for the old orthodox religions which appeal to few among the young, and those as a rule the least intelligent and the most obscurantist something wh

If there were in the world today any large number of people who desired their own happiness more than they desired the unhappiness of others, we could have a paradise in a few years.
If a philosophy is to bring happiness it should be inspired by kindly feelings. Marx pretended that he wanted the happiness of the proletariat; what he really wanted was the unhappiness of the bourgeois.
Happiness is not best achieved by those who seek it directly.
A man who has once perceived, however temporarily and however briefly, what makes greatness of soul, can no longer be happy if he allows himself to be petty, self-seeking, troubled by trivial misfortunes, dreading what fate may have in store for him. The
A good notation has a subtlety and suggestiveness which at times make it almost seem like a live teacher.

5. a priori Logical propositions are such as can be known a priori without study of the actual world.
4. Form The 'form' of a proposition is that, in it, which remains unchanged when every constituent of the proposition is replaced by another.
3. Formality Thus the absence of all mention of particular things or properties in logic or pure mathematics is a necessary result of the fact that this study is, as we say, 'purely formal'.
2. Analytic It is clear that the definition of 'logic' or 'mathematics' must be sought by trying to give a new definition of the old notion of 'analytic' propositions.
1. Generality Certain characteristics of the subject are clear. To begin with, we do not in this subject deal with particular things or particular properties: we deal formally with what can be said about any thing or any property. We are prepared to say that one and one are two, but not that Socrates and Plato are two....

Drunkeness is temporary suicide: the happiness that it brings is merely negative, a momentary cessation of unhappiness.
