A new, original, and evidence-based concept that unites science with religion Original and significant conclusions that reprise the work of a great philosopher Relativity and quantum theory, united with consciousness, require a new world-view David Roper reprises the Principles of Human Knowledge, as advanced by Bishop George Berkeley, and presents a viable theory of the true nature of reality based upon a striking new model of space-time, world-lines and consciousness. He shows how this theory accounts for the unification of a wide variety of hitherto unresolved problems. They include space-time, world-lines, time, natural laws, cause and effect, memory, freewill, determinism, precognition, the mind-brain problem, heaven, and the place of prayer in the world. Readership: Philosophers, theologians and scientists with an interest in the logical implications and consequences of work carried out by the physical sciences. It will also interest a more general readership for the many famous, historical references that correlate in an error-free way to their foreknowledge.
