Modern Philosophy, Philosophy of Physics, Philosophy of language, Neurobiology, Philosophy of Perception, Modern Political Philosophy—all share a common philosophical foundation: atomism. The theory of atomism that is developed in the writing of Einstein, Bohr, Schrodinger, and Reichenbach shares the same metaphysical roots as the atomism of Gottlob Frege, Ludwig Wittgenstein, and Bertrand Russell. These atomisms share the same foundation as the one developed by John Locke and David Hume. Until now, the full philosophic history, and metaphysical foundations of this theory of atomism have not been presented. Atomist theory not only contains cultural premises of great significance for the fate of public opinion, but it is also an eminently political doctrine, incompatible with the most modest degree of democracy. The atomist theory happens to be false. In this case, the truth does matter.
