One of the most misleading representational techniques in our language is the use of the word 'I.'

Where two principles really do meet which cannot be reconciled with one another, then each man declares the other a fool and a heretic

The world of those who are happy is different from the world of those who are not.

The world is made up of facts, not things.

Mathematics is a logical method. . . . Mathematical propositions express no thoughts. In life it is never a mathematical proposition which we need, but we use mathematical propositions only in order to infer from propositions which do not belong to mathematics to others which equally do not belong to mathematics.

Russell's books should be bound in two colours, those dealing with mathematical logic in red - and all students of philosophy should read them; those dealing with ethics and politics in blue - and no one should be allowed to read them.
