项目摘要

I have considered the possibility of the realism through investigations of the interpretation problem of quantum mechanics, supported by Grant-in-Aid for Scientific Research. Scientific realism is the position that accepts as objectively real the picture given by scientific theories confirmed enough. In the history of science, each scientific theory has been presented with its proper image of the world. However, in quantum mechanics that appeared at the beginning of the twentieth century, its mathematical formalism was presented as an algorithm connecting observational results, without any consistent picture of the world. Physicists accept the particle image of the world in some cases, and the undulation image in other cases. Thus they cannot give the consistent picture to the world. This means that they could not adopt scientific realism. Because the world picture itself is not given to hold scientific realism. I have formulated the theory of relativity so that its components directly correspond to elements of the reality, examined the modal interpretation of quantum field theory under my formulation, and announced in the meeting of Philosophy of Science Society Japan the conclusion that the so-called field of operators cannot be regarded as real. And I have considered the conditions to be posed to our knowledge of the world in case that the world should be essentially probabilistic, and examined whether the propensity interpretation of probability hold or not in that case. The positive conclusion I reached to was announced in the symposium of the Japan Association for Philosophy of Science and in the seminar of Nagoya Philosophy Society. Part of that conclusion was published in Journal of the Japan Association for Philosophy of Science 32(2).

我在科学研究补助金的支持下，通过对量子力学解释问题的研究，考虑了实在论的可能性。科学实在论是一种把科学理论所给出的图景充分证实为客观真实的立场。在科学史上，每一种科学理论都有其恰当的世界形象。然而，在20世纪初出现的量子力学中，它的数学形式被呈现为一种连接观测结果的算法，没有任何一致的世界图景。物理学家在某些情况下接受世界的粒子图像，而在其他情况下接受波动图像。因此，他们不能给世界一致的画面。这意味着他们不能采用科学实在论。因为世界图景本身并没有被赋予科学实在论。我已经表述了相对论，使它的组成部分直接对应于现实的元素，在我的表述下检验了量子场论的模态解释，并在日本科学哲学学会的会议上宣布了所谓的算子场不能被视为实在的结论。我考虑了在世界本质上是概率性的情况下我们认识世界的条件，并检验了在这种情况下概率的倾向解释是否成立。我在日本科学哲学协会的研讨会和名古屋哲学学会的研讨会上宣布了我得出的积极结论。该结论部分发表在《日本科学哲学协会学报》32(2)上。
