In this book Einstein has expressed his personal views about the purpose and ideals of life, democracy and dictatorship, war and peace, mystery and religion. He says we live for the sake of fellow beings because our happiness depends on the smiles and welfare of others.
He thinks that his fellowman work very hard in order to make his life comfortable, so he must repay in the same measure. He is against class differences, which he thinks are contrary to justice and are based on force and compulsion. He believes in simple living. Philosophers believes in perfect freedom, but Einstein does not agree with them. He thinks the actions of an individual are determined by environment forces as well as by his natural urges.
He believes in the philosophy of Schopenhauer who says that man is not master of his will.
