Recently, we proposed quantum language (in short,
QL) as a mathematical realization of the
quantum mechanical worldview. QL has the form of “axioms (measurement and causality)” + “linguistic Copenhagen
interpretation”. And
the quantum language can cover both quantum and classical systems. In this way,
QL is one of the most powerful scientific theories beyond statistics, and I
believe QL is the only dualism that has been scientifically successful. If so,
the history of Western philosophy (mostly dualistic idealism) can be discussed
from the quantum linguistic point of view. In this paper, we discuss the
similarities between quantum language and Cartesian and Kantian epistemology.
We conclude that “Axioms
(measurement and causality)” can be
characterized as a study belonging to Continental rationalism that sought to
advance Descartes’s
mind-body dualism. On the other hand, “linguistic Copenhagen interpretation” belongs to British
empiricism (Locke, Berkeley, Hume, Kant), which can be characterized as the
epistemological application of Descartes’s mind-body dualism.The conventional theory is
that continental rationalism and British empiricism were synthesized by Kant.
Therefore, I think it is necessary to weigh the usual conventional theory with
our claims.
