Americans and Englishmen, when they become acquainted with the Balkans, feel an astonished contempt when they study the mutual enmities of Bulgarians and Serbs, of Hungarians and Rumanians. It is evident to them that these enmities are absurd and that the belief of each little nation in its own superiority has no objective basis. But most of them are quite unable to see that the national pride of a Great Power is essentially as unjustifiable as that of a little Balkan country.

I think we ought always to entertain our opinions with some measure of doubt. I shouldn't wish people dogmatically to believe any philosophy, not even mine.

I suggest to young professors that their first work should be written in a jargon only to be understood by the erudite few. With that behind them, they can ever after say what they have to say in a language 'understand of the people.'

The social psychologist of the future will have a number of classes of school children on whom they will try different methods of producing an unshakable conviction that snow is black. When the technique has been perfected, every government that has been in charge of education for more than one generation will be able to control its subjects securely without the need of armies or policemen.

Men fear thought as they fear nothing else on earth - more than ruin, more even than death.

There is... in our day, a powerful antidote to nonsense, which hardly existed in earlier times - I mean science. Science cannot be ignored or rejected, because it is bound up with modern technique; it is essential alike to prosperity in peace and to victory in war. That is, perhaps from an intellectual point of view, the most hopeful feature of our age, and the one which makes it most likely that we shall escape complete submersion in some new or old superstition.

I conclude that, while it is true that science cannot decide questions of value, that is because they cannot be intellectually decided at all, and lie outside the realm of truth and falsehood. Whatever knowledge is attainable, must be attained by scientific methods; and what science cannot discover, mankind cannot know.
