%0 Journal Article %T Bohr¡¯s Philosophy and Changes of Physical Language Foundations %A Mladen Domazet %J Prolegomena %D 2004 %I Society for the Advancement of Philosophy, Zagreb %X Ever since the beginning of development of Quantum Mechanics there was a metaphysical division between the ¡°macro¡± world as described in ¡°everyday language¡± and the ¡°micro¡± world described by quantum formalism (especially due to entanglement of two or more logically conflicting states). A discussion is offered of the need to reunite these arbitrarily divided worlds through an overview of the main interpretations of the formalism. Bohr¡¯s Copenhagen interpretation, as well as the problems it faces due to EPR thought experiment, is presented in greater detail. It is claimed that Bohr¡¯s answers to the said experiment demand more than a restriction of everyday descriptive metaphysics, when describing phenomena at the micro-level. Thus, the special place Bohr¡¯s interpretation takes among other interpretations of the formalism is forfeited. It is also shown that MacKinnon¡¯s more detailed schema aiming to connect the theoretical and everyday language cannot be applied to EPR conclusions and Bohr¡¯s reply to those. MacKinnon¡¯s own modifications of the ¡°everyday language¡± induced by the mathematical conclusions of Quantum Mechanics are considered too radical and too coarse to take the vacated special place among formalism interpretations. %K Measurement problem %K interpretations of formalism of Quantum Mechanics %K N.
