Summary: 'All meaning is an angle.' With this intriguing aphorism, Arthur Young introduces his bold exploration of the fundamental relationships underlying reality. 'Meaning' he explains, 'is in general a kind of 'relationship'...for example, let us take two men competing in a tennis match. They are opponents. They face each other. Their positions, both literally and metaphysically, are represented by an angle of 180 degrees, or a diameter. We refer to diameter when we say that two opinions are diametrically opposed. '

Young conceives of this book as an essay in philosophy, but philosophy is the older sense, encompassing the natural sciences, exploring the implications of science, and dealing with the relationship of the knower and the known. At the heart of the book is what he calls the 'Rosetta Stone of meaning,' a diagram of relationships based upon the twelve measure formulae of modern physics, which he uses to describe the interaction of mind with matter.
