Ludwig Wittgenstein is one of the greatest and most fascinating philosophers of all time. His Tractatus Logico-Philosophicus, composed in a series of remarkable numbered propositions, was the only book he published in his lifetime. He tackles nothing less than the question of whether there is such a thing as a logically perfect language and, armed with it, what we can say about the nature of the world itself. Pushing the limits of language, logic and philosophy, the Tractatus is a brilliant, (...) cryptic and hypnotic tour de force, exerting a major impact on twentieth-century philosophy and stirring the imagination today. With a new foreword by Ray Monk. (shrink)

One of the cornerstone books of Western philosophy, Critique of Pure Reason is Kant's seminal treatise, where he seeks to define the nature of reason itself and builds his own unique system of philosophical thought with an approach known as transcendental idealism. He argues that human knowledge is limited by the capacity for perception and attempts a logical designation of two varieties of knowledge: a posteriori, the knowledge acquired through experience; and a priori, knowledge not derived through experience. This accurate (...) translation by J. M. D. Meiklejohn offers a simple and direct rendering of Kant's work that is suitable for readers at all levels. (shrink)

Recently we proposed “quantum language”, which was not only characterized as the metaphysical and linguistic turn of quantum mechanics but also the linguistic turn of Descartes = Kant epistemology. And further we believe that quantum language is the only scientifically successful theory in dualistic idealism. If this turn is regarded as progress in the history of western philosophy (i.e., if “philosophical progress” is defined by “approaching to quantum language”), we should study the linguistic mind-body problem more than the epistemological mind-body (...) problem. In this paper, we show that to solve the mind-body problem and to propose “measurement axiom” in quantum language are equivalent. Since our approach is always within dualistic idealism, we believe that our linguistic answer is the only true solution to the mindbody problem. (shrink)
