Abstract

Recently I proposed “QL (=quantum language)” (or, “the linguistic Copenhagen interpretation of quantum theory”), which was not only characterized as the metaphysical and linguistic turn of quantum mechanics but also as the scientific understanding of Descartes=Kant epistemology. Namely, quantum language is the scientific final goal of dualistic idealism. It has a great power to describe classical systems as well as quantum systems. In this research report, quantum language is seen as a fundamental theory of statistics and reveals the true nature of statistics. I hope the readers to enjoy the beautiful world of dualistic idealism.
