While the dogmatist is harmful, the sceptic is useless ...; one is certain of knowing, the other of not knowing. What philosophy should dissipate is certainty, whether of knowledge or of ignorance. Knowledge is not so precise a concept as is commonly thought. Instead of saying 'I know this', we ought to say 'I more or less know something more or less like this'. ... Knowledge in practical affairs has not the certainty or the precision of arithmetic.
Bertrand RussellIt is essential to happiness that our way of living should spring from our own deep impulses and not from the accidental tastes and desires of those who happen to be our neighbors, or even our relations.
Bertrand RussellIdeas and principles that do harm are as a rule, though not always, cloaks for evil passions.
Bertrand RussellA world full of happiness is not beyond human power to create; the obstacles imposed by inanimate nature are not insuperable. The real obstacles lie in the heart of man, and the cure for these is a firm hope, informed and fortified by thought.
Bertrand RussellTo abandon the struggle for private happiness, to expel all eagerness of temporary desire, to burn with passion for eternal things-this is emancipation, and this is the free man's worship... United with his fellow men by the strongest of all ties, the tie of a common doom, the free man finds that a new vision is with him always, shedding over every daily task the light of love.
