This collection of essays is concerned with different ways of knowing; the particular problems of philosophy; and the ultimate nature of matter. They reveal Russell's lifelong preoccupation: the disentanglement with ever-increasing precision of what is subjective or intellectually cloudy from what is objective or capable of logical demonstration. In them we can see the Russell method in operation: intellectual analysis dissecting a problem to its bare bones. Also included is Bertrand Russel's celebrated essay "A Free Man's Worship". In it he maintains that a new and deeper faith can be constructed, not faith in a theological sense but faith in the power of reason; his faith in man's capacity to create his own world through his own effort.
