对偶性是弦论框架内的核心概念之一,其主要立场是“理论形式或物理系统的描述似乎十分不同,却导致了相同的物理学”。这种奇特的对偶对称对科学哲学而言意义非凡,许多传统的哲学主张能以此获得拓展和深化。其中,它所涉及的主要哲学问题有:理论的非经验确证、亚决定性、理论间的同一与个性化、系统观、结构实在论、科学生成及其演化上的方法论。 Duality is one of the central concepts within the framework of string theory whose main stance is that “the description of the theoretical form or physical system seems quite different, but leads to the same physics.” This peculiar duality symmetry is of great significance to the philosophy of science, and many traditional philosophical ideas can be extended and deepened. Among them, the main philosophical problems it involves are: the inexperience and confirmation of theory, the sub-decisiveness, the unity and individuation among theories, the systematic view, the structural realism, the methodology of scientific production and its evolution.
