`This book is a model of philosophical lucidity.' - Philip Toynbee, The Observer`The most careful and systematic discussion of the philosophy of ethics he has written.' - Herald Tribune`I have once again been captivated by the strength of Lord Russell's intellect, the elegance of his prose and the causticity of his wit. He is the Voltaire of his time, and one likes him or dislikes him accordingly.' - Sunday Times`The best course is to give him up as hopeless and read everything he writes.' - Saturday Review`A book which commends intelligence, friendship, courage, hope and love surely has much of right on its side.' - The Scotsman`To converse with a man of great intelligence is always a delight, and when we read the works of Lord Russell we feel ourselves in his presence.' - The Listener
