这篇文章提出了一种新颖的方法来解决备受讨论的问题，即哪些对称性具有“直接的经验意义”，哪些没有。该方法基于希拉里·格里夫斯和大卫·华莱士最近提出的框架的发展，他们声称，与物理学哲学家的标准民间传说相反，“局部”对称性可能具有不亚于“全局”对称性的直接经验意义。部分证明了标准民间传说的正确性，这里的结果是从许多看似合理的假设中得出的，该假设表明局部对称性确实没有直接的经验意义。考虑解释结果的方法并概述可能的道德。
The article proposes a novel approach to the much discussed question of which symmetries have 'direct empirical significance' and which do not. The approach is based on a development of a recently proposed framework by Hilary Greaves and David Wallace, who claim that, contrary to the standard folklore among philosophers of physics, 'local' symmetries may have direct empirical significance no less than 'global' ones. Partly vindicating the standard folklore, a result is derived here from a number of plausible assumptions, that states that local symmetries can indeed have no direct empirical significance. Ways to interpret the result are considered and possible morals are outlined.
