Abstract
The problem of mind and consciousness cannot be treated as an object of science without much difficulty. Inevitably there is the self-contradiction that the work itself in science and thinking is an object of thought. In this meaning, we need to get back to the fundamental problem of how the world is perceived. The fundamental concept of quantum theory includes essentially unsolved problems such as the observation problem. In this paper, we begin to consider this fundamental problem in quantum theory and discuss the possibility of a description of mind in terms of quantum theory.
