It is shown that the validity of Ludwig Boltzmann’s statistical approach to thermodynamical asymmetry depends on the metaphysical standpoints concerning time. Price advocates one metaphysical standpoint that denies the direction of time itself, the denial leads to a difficulty in explaining the thermodynamical asymmetry. In the case of Price’s strategy, the direction of the law does not warrant as much explanation as does the constraint condition on the past, which does not work. In contrast, our study advocates the other metaphysical standpoint. Our strategy suggests that the constraint condition on the past does not warrant as much explanation as does the direction of the law. These findings are exactly opposite to those of Price.

Popperʼs analysis of the conceptual problems of quantum mechanics and the propensity interpretation of probability are reviewed. Although these theories do not prove to be sufficient in resolving issues with regard to quantum mechanics, there exists a modern theory, stochastic mechanics, that validates Popperʼs framework. Two aspects of his idea in particular, are essential for stochastic mechanics to explain quantum mechanics without any conceptual confusion. One is that a whole experimental arrangement determines a propensity field. The other is that propensity is objective and is qualified to be considered as a physical entity. This relationship between Popperʼs philosophy and stochastic mechanics is illustrated with an example of the double-slit experiment, wherein Popperʼs theory is proved.

投稿論文はじめに2. 確率過程量子化の動機と歴史3. 確率過程量子化の理論4. 確率過程量子化の古典性5. 古典的確率過程と物理的概念の衝突6. なぜ時間対称性か7. 確率が先か確率振幅が先か8. さいごにWe show that the theory of quantum stochastic processes, which is one of the formalisms of quantum mechanics, is a generalization of Newtonian mechanics so as to be applied to the motion which has noise. We notice that the time-symmetry of stochastic processes plays an essential role in the generalization. The approach of the theory of quantum stochastic processes restricts our investigation to the timesymmetry of stochastic processes, while the interpretational problems of quantum mechanics are so chaotic that we can not specify the problems. The subjective probability, which represents our ignorance on the deterministic world, is a timeasymmetrical prediction either from the past to the future or from the future to the past, and satisfies the additivity of probability. We first doubt the time-asymmetry of objective stochastic processes which stochastic processes have been supposed to have. Then, necessarily we are forced to doubt the additivity, too. The timesymmetry of objective stochastic processes mentioned above leads to the conclusion that the strangeness of quantum mechanics is not the strange-ness of mechanical parts of quantum mechanics. The quantum mechanical strangeness results from our biased view about the concept of probability. Finally, an answer to the question whether or not quantum stochastic processes are classically mechanical is given.
