We are taking the case of ‘quantum mechanics’. The physicist  Anton Zeilinger would argue: ” When analyzing the various interpretations of quantum mechanics one notices that each understanding contains an element that escapes a complete and exhaustive description. This element is always associated with the stochasticity of the individual event in the process of quantum measurement. It seems that the implications of this limit in any interpretation of the world are not sufficiently appreciated, with notable exceptions, for example, Heisenberg, Pauli and Wheeler. If we assume that a deeper foundation of quantum mechanics is possible, the question arises about what features should have this philosophical foundation. Now, in particular, the Austrian physicist Erwin Schrödinger illustrates the problem of quantum mechanics applied to everyday objects. He described an ideal experiment in which the overlap of two distinct atomic states can be "transferred" to a visible object, definitely going against common sense.

The reason why it is not possible to observe quantum effects in macroscopic objects, is that these are inevitably coupled in any way with the external environment. See the so-called “paradox” of Schrödinger's cat (I’d suggest to read by yourself the long story).

To underscore the difficulty in understanding the relationship between the microscopic and macroscopic world, since in the first applies the quantum superposition of states while in the second the classic behavior of cats denies. This means that the system atom + cat becomes, within a very short time, 'woven' with the external environment, so that - in fact - it is no longer described by a quantum superposition: in other terms, loses consistency.

Niels Bohr, with his usual language a bit 'dark and cryptic’ points out the “essential inadequacy in terms of the usual natural philosophy for a rational description of the physical phenomena of the type we deal in quantum mechanics". (see  N. Bohr, Essays 1958-1962: Atomic Physics And Human Knowledge (Richard Clay And Company, Ltd., 1963)

As we are interested in the philosophical implications of ‘quantum mechanics’, generally speaking, the philosophical concept that is at the basis of the scientific venture we have the “paradox” of Schrödinger's cat. Summarized in the initial postulates and articulated on the analysis of the measurement process, it can not change with the succession of scientific theories. This happens also because since it regards the basic assumptions, it coincides with that of common sense rationally oriented which accompanied and supported humanity a long way in its history.

If we concentrate on the relationship between classical physics and quantum mechanics, the philosophical reference should not be changed. However, this new vision of the world registered “unavoidable philosophical consequences: « the mathematical method of investigation of physical phenomena is and remains valid, but at deeper levels of the mind the physicist is forced to open to new horizons of thought that are linked in part to the Platonic philosophy.

Then, the historical development of science shows that scientific theories can be and are inspired by philosophical positions; or that new scientific knowledge can contribute to possible changing philosophical views. This intertwining can be fruitful, but only if the fields of investigation are kept strictly separate. Assertions of the type "before measurement the photons of the pair have not defined polarization" if not amenable to experimental direct or indirect verification (and, therefore, metaphysical), may not enter within the formal descriptions (mathematized) of physics. Their use led, on the one hand, to the alleged non-locality of quantum mechanics; on the other has given nourishment to philosophical positions that helps the observer to build "reality".

In the Stanford Encyclopedia of Philosophy we read:” [in approaching] the philosophical discussion of quantum mechanics, the more one learns about the relationships about how the spaces of simple systems relate to those of complex ones, and about the equation which describes how state-vectors move through the space, the better will be one's appreciation of both the nature and the difficulty of the problems associated with the theory. The funny backwards thing about quantum mechanics, the thing that makes it endlessly absorbing to a philosopher, is that the more one learns, the harder the problems get”.
