Henry Stapp (a physicist at Berkeley) in his book The Mindful Universe states: "Let there be no doubt about this point. The original form of quantum theory is subjective, in the sense that it is forthrightly about relationships among conscious human experiences, and it expressly recommends to scientists that they resist the temptation to try to understand the reality responsible for the correlations between our experiences that the theory correctly describes. The following brief collection of quotations by the founders gives a conspectus of the Copenhagen philosophy: Heisenberg (1958a, p. 100): The conception of objective reality of the elementary particles has thus evaporated not into the cloud of some obscure new reality concept but into the transparent clarity of a mathematics that represents no longer the behavior of particles but rather our knowledge of this behavior" As philosophers, what is your take on these statements? It appears to me that these quite distinguished physicists are saying that physics is no longer of an ontological nature, but it has been found to be, irremediably, of an epistemological nature?
