A smile happens in a flash, but its memory can last a lifetime.
Frege has the merit of ... finding a third assertion by recognising the world of logic which is neither mental nor physical.
On the one hand, philosophy is to keep us thinking about things that we may come to know, and on the other hand to keep us modestly aware of how much that seems like knowledge isn't knowledge
I like mathematics because it is not human and has nothing particular to do with this planet or with the whole accidental universe - because, like Spinoza's God, it won't love us in return.
It has become a commonplace that aggressiveness also often has its roots in fear. I am inclined to think that this theory has been pushed too far. [...] The type of aggressiveness that is the outcome of timidity is not, I think, that which inspires great leaders; the great leaders, I should say, hav
What is wanted is not the will to believe, but the will to find out, which is the exact opposite.
My first advice on how not to grow old would be to choose you ancestors carefully.
Freedom in general may be defined as the absence of obstacles to the realization of desires.
But if thought is to become the possession of many, not the privilege of the few, we must have done with fear. It is fear that holds men back - fear lest their cherished beliefs should prove delusions, fear lest the institutions by which they live should prove harmful, fear lest they themselves shou
This is one of those views which are so absolutely absurd that only very learned men could possibly adopt them.
A million million years gives us some time to prepare for the end . . . let us make the best of it.
I do not myself feel that any person who is really profoundly humane can believe in everlasting punishment.
The teacher, like the artist and the philosopher, can perform his work adequately only if he feels himself to be an individual directed by an inner creative impulse, not dominated and fettered by an outside authority.
Respectability, regularity, and routine - the whole cast-iron discipline of a modern industrial society - have atrophied the artistic impulse, and imprisoned love so that it can no longer be generous and free and creative, but must be either stuffy or furtive.
All the conditions of happiness are realized in the life of the man of science.
I think it would be just to say the most essential characteristic of mind is memory, using this word in its broadest sense to include every influence of past experience on present reactions.
Change is scientific; progress is ethical; change is indubitable, whereas progress is a matter of controversy.
The scientific attitude of mind involves a sweeping away of all other desires in the interests of the desire to know-it involves suppression of hopes and fears, loves and hates, and the whole subjective emotional life, until we become subdued to the material, able to see it frankly, without preconce
When you want to teach children to think, you begin by treating them seriously when they are little, giving them responsibilities, talking to them candidly, providing privacy and solitude for them, and making them readers and thinkers of significant thoughts from the beginning. Thatâ€™s if you want
Life is nothing but a competition to be the criminal rather than the victim.
In emancipation from the fears that beset the slave of circumstance he will experience a profound joy, and through all the vicissitudes of his outward life he will remain in the depths of his being a happy man.
Is a man what he seems to the astronomer, a tiny lump of impure carbon and water crawling impotently on a small and unimportant planet? Or is he what he appears to Hamlet? Is he perhaps both as once?
Brief and powerless is man's life; on him and all his race the slow, sure doom falls pitiless and dark.
You find as you look around the world that every single bit of progress in humane feeling, every improvement in the criminal law, every step toward the diminution of war, every step toward better treatment of the colored races, or every mitigation of slavery, every moral progress that there has been
Morality in sexual relations, when it is free from superstition, consists essentially in respect for the other person, and unwillingness to use that person solely as a means of personal gratification, without regard to his or her desires.
In detective stories . . . I alternately identify myself with the murderer and the huntsman-detective, but . . . there are those to which this vicarious outlet is too mild.
To be happy in this world, especially when youth is past, it is necessary to feel oneself not merely an isolated individual whose day will soon be over, but part of the stream of life slowing on from the first germ to the remote and unknown future.
Psychology often becomes the disease of which it should be the cure.
I read Zuleika Dobson with pleasure. It represents the Oxford that the two World Wars have destroyed with a charm that is not likely to be reproduced anywhere in the world for the next thousand years.
The theoretical understanding of the world, which is the aim of philosophy, is not a matter of great practical importance to animals, or to savages, or even to most civilised men.
