Abstract
After a brief survey of arguments for a unitary particle theory of matter, offered by the writer in previous publications, the following new items are discussed. (1) The wave part of the dual aspect of matter, resting on the translation formula λ=h/p, is not covariant in the nonrelativistic domain. And relativistically, it is untenable not only on methodological grounds, but because it leads to obvious contradictions to elementary experience, e.g., in the equilibrium between a material oscillator and radiation. (2) The photon story as usually presented is rectified historically and factually. (3) The previous derivation by the writer of quantum mechanical theory from a nonquantal background is supplemented, in order to be conclusive, by the postulate that the general probability relation is to become the ordinary addition law in the average. (4) Quotations from the writings of prominant dualists, intended by the latter to support their ideology, disclose a fantastic disarray of pseudophilosophical standpoints which can be cleared up only by repudiating the alleged dual nature of matter and of light and by ceasing to constantly mix up the contrast between particles and fields with that between particles and waves, and by returning to a strictly unitary aspect
