Argues that humans can play an active role in their continuing evolution and considers the relationship between knowledge and life

For David Deutsch, a young physicist of unusual originality, quantum theory contains our most fundamental knowledge of the physical world. Taken literally, it implies that there are many universes “parallel” to the one we see around us. This multiplicity of universes, according to Deutsch, turns out to be the key to achieving a new worldview, one which synthesizes the theories of evolution, computation, and knowledge with quantum physics. Considered jointly, these four strands of explanation reveal a unified fabric of reality that is both objective and comprehensible, the subject of this daring, challenging book. The Fabric of Reality explains and connects many topics at the leading edge of current research and thinking, such as quantum computers (which work by effectively collaborating with their counterparts in other universes), the physics of time travel, the comprehensibility of nature and the physical limits of virtual reality, the significance of human life, and the ultimate fate of the universe. Here, for scientist and layperson alike, for philosopher, science-fiction reader, biologist, and computer expert, is a startlingly complete and rational synthesis of disciplines, and a new, optimistic message about existence.

Alfred Schutz was born in Vienna on April 13, 1899, and died in New York City on May 20, 1959. The year 1969, then, marks the seventieth anniversary of his birth and the tenth year of his death. The essays which follow are offered not only as a tribute to an irreplaceable friend, colleague, and teacher, but as evidence of the contributors' conviction of the eminence of his work. No special pleading is needed here to support that claim, for it is widely acknowledged that his ideas have had a significant impact on present-day philosophy and phenomenology of the social sciences. In place of either argument or evaluation, I choose to restrict myself to some bi~ graphical information and a fragmentary memoir. * The only child of Johanna and Otto Schutz (an executive in a private bank in Vienna), Alfred attended the Esterhazy Gymnasium in Vienna, an academic high school whose curriculum included eight years of Latin and Greek. He graduated at seventeen - in time to spend one year of service in the Austrian army in the First World War. For bravery at the front on the battlefield in Italy, he was decorated by his country. After the war ended, he entered the University of Vienna, completing a four year curriculum in only two and one half years and receiving his doctorate in Law.
