Complementarity is the central component of the so-called Copenhagen interpretation of quantum mechanics, which Niels Bohr first presented at the Como and Solvay Conferences in 1927. The content of Bohr's speech was published in an article entitled "the quantum postulate and recent development of Atomic Theory" in 1928. The purpose of this study is to formulate Bohr's philosophical approaches by content analysis of his paper (1928) related to complementarity. The research method is based on the conceptual analysis of the content and text of this paper (1928) from which conceptual inferences can be deduced, and based on them, philosophical approaches are tried to be formulated. Finally, the four philosophical approaches including Unificationism, empiricism (positivistic and metaphysical), anti-causality and indeterministic, as well as anti-realism can be formulated. In addition, for more accurate inferences, we need to refer to the following works of Bohr, or in other words, "Bohr from Bohr's point of view".

The common understanding of Copenhagen interpretation of the uncertainty principle and indeterminism in quantum physics is that it is a negation of causal relationships. Having the relationship between the existence of God and causality in mind, some advocates of ontological naturalism assert that by negating causality in modern physics, there remains no room for belief in God as the necessary cause of the world and His actions in it. To examine this claim, I will explain briefly the quantum theory, Copenhagen interpretation of uncertainty principle, and its epistemological position. Next, I will investigate its relationship with causality and divine actions. The article concludes that not only is there no conflict between Copenhagen interpretation and causality, but the former is based on the latter and has complete coherence with the belief in God and His actions in the world. Compared to classical physics, its consistency with direct and special divine actions in the world is more.

Heisenberg is one of the founders of quantum mechanics, and one of the pioneers and intellectual leaders of the Copenhagen interpretation of quantum mechanics. He proposed in two seminal papers in 1925 and 1927, the fundamentals of matrix mechanics (1925) as the first formalism of quantum mechanics, and then the uncertainty relations (1927) as one of the essential components of the Copenhagen interpretation. The purpose of this paper is to formulate Heisenberg's philosophical approaches during the formation of quantum mechanics and its Copenhagen interpretation. The main question of the paper is whether philosophical approaches can be formulated in the development of quantum mechanics through Heisenberg's works? To answer this question, two seminal papers by Heisenberg (1925 and 1927) are examined. The research method of the paper is based on the content analysis of the text (physics) of Heisenberg's papers. The findings of this study show that three crucial principles - observability, correspondence, and analogy-can be formulated from Heisenberg's 1925 paper, which has played a key role in the formation of the fundamentals of matrix mechanics. Moreover, from his 1927 paper, some issues are addressed including interpretation, understanding and classical-quantum relation, the role of experience and measurement, the subject of causality, as well as reality. Finally, it is concluded that through these works of Heisenberg, four philosophical approaches can be formulated including empiricism, Unificationism, indeterminism, and anti-causality, as well as anti-realism, which themselves include other sub-approaches.

Philosophical conclusions from Copenhagen interpretation of quantum mechanics including the rejection of realism، negation of causality and Lack of determination on nuclear or atomic events and etc، lead to a gap or twofoldness between classical and Quantum physics. In this article، we will show this gap and there is an attempt to offer responses to major claims of Copenhagen school based on Popper’s falsificationism، its tools and attributes. We also contend that the mentioned gap can be restored with an appropriate philosophical interpretation and Once again، we can return unity to the philosophy of physics.

It is a common view that, most of the elements of Copenhageninterpretation, as the first and the most famous interpretation ofquantum mechanics, is rooted historically and philosophically, logicalpositivism. The aim of this paper is to show that, philosophically,pragmatism supports Copenhagen interpretation more intensively,whether or not the initiators of the interpretation, such as Niels Bohr asthe most important figure of the interpretation, were aware of that. Weproclaim that some elements of the interpretation, which are consistentwith logical positivism, are perfectly supported by pragmatism. Someof these elements are: weak objectivism, senselessness of the conceptof “thing in itself”, instrumentalist approaches to theories, and theavoidance to deal with ontological issues irrespective of experiment.Furthermore, and more particularly, it is argued that pragmatismespouses some of other fundamental and important elements ofCopenhagen interpretation such as holism, uncertainty principle, andcomplementarity.
