量词可变学说是一种宣称不存在描述世界的最佳语言的学说。在本文中,我将考察该学说对于那些强调关注结构的重要性的科学观,诸如结构实在论和结构经验论的意蕴。本文将论证,在量词可变学说的与境中,结构实在论将会显现出一些显著的问题,而结构经验论则无须面对这些问题。 The rhetoric of quantification is a doctrine that claims that there is no best language to describe the world. In this article, I examine the scientific view of the doctrine for those that emphasize the importance of structure, such as structural realism and structural empiricism. This article will argue that structural realism will show some notable problems in the context of variable-word theory, while structural empirical theory need not face these problems.
