Quantum mechanics: a realist reflection about the paradoxes

Luigi E. Picasso

Michel Bitbol

Instead of either formulating new metaphysical images (as realists would do) or rejecting any metaphysical attempt (as empiricists would do), the case of quantum mechanics might well require from us a complete redefinition of the nature and task of metaphysics.The sought redefinition can be performed in the spirit of Kant, according to whom metaphysics is the discipline of the boundaries of human knowledge.This can be called a "reflective" conception of metaphysics.In this paper, each one of the most popular "interpretations" of quantum mechanics is shown to be naturally associated with a variety of Kant-like reflective metaphysics.Then, the two major "paradoxes" of quantum mechanics (the measurement problem and the EPR correlations) are reformulated by way of this reflective attitude, and they are thereby "dissolved".Along with this perspective, quantum mechanics becomes one of the most elegant and understandable theories of the history of physics in addition of being one of the most efficient.The only point that must be clarified is why it looks culturally so difficult to accept a reflective and non-ontological standpoint on physical theories.

Abstract In this second part of the series of comments for foundation of quantum mechanics,we concentrate ourselves in the EPR paradox.The recent development of this field is critically surveyed and our comments or suggestions for further investigations are added.We show that quantum mechanics can be rewritten realistically by using the so-called hidden variables.The local realistic theory is the common feature in most theory of natural science.Quantum mechanics also has this common feature and is not an exceptional theory in science.|量子力学の基礎についてのコメントと題するシリーズの第2部では、EPRパラドックスに重点をおく。この分野の最近の発展が批判的に概観され、さらなる研究へのコメントと示唆が付加されている。量子力学はいわゆるかくされた変数を用いて実在論的に書き直すことが可能である。この局所実在論は多くの自然科学の理論で共通にみられることである。量子力学もまたこの共通点をもち、科学における例外的な理論ではない。

We propose a realistic and nonlocal interpretation for quantum mechanics, which requires new mathematical, physical and philosophical foundations for space-time. Our theory violates Bell's inequality. We also discuss the cat paradox.
