Upon the completion of his Principia Mathmatica, in collaboration with Dr. Alfred North Whitehead, Bertrand Russell reached the conclusion that little could be achieved by writings addressed exclusively to specialists. Abstract pursuits gave way to a quest for a better way of life, where co-operation, not competition, is the road to happiness. These essays reveal the quintessence of Bertrand Russell’s enlightened philosophy. They are for readers who are conscious of the social and political problems of our age and who seek solutions under the guidance of science and a humane philosophy.
