Quantum

A. These are not my words. The unity of opposites (in the sense of a logical contradiction) is a meaningless concept. Schrödinger's cat does not contradict this because it does not involve a logical contradiction. The cat is in a superposition of alive and dead, but it is not correct to say that it is both alive and dead. In a borrowed way, it can be said that it is half alive and half dead (and not both alive and dead). B. Even in quantum theory, it is not clear that consciousness changes reality. The concept of measurement there is still unclear. Beyond that, quantum theory deals only with the micro. The solution you proposed is essentially the Kantian solution. It's not that measurement changes the world, but that the world is painted in the colors of the measurer. There is also an idealistic solution. To those who see one of these – to their health. It doesn't seem so to me.
