lexicon(词汇系统①)是库恩晚年思想中最重要的概念,也是范式的替代物。库恩从语言层面讨论分类学范畴和词汇系统,不再从知觉、方法论和本体论讨论不可通约性,将不可通约发展为词汇系统间的不可翻译性。库恩所阐释的词汇系统具有一定程度的本体论特质,与其世界观念密切相关。从范式到词汇系统的演变表明库恩的思想发生变化,然究其实质其实一以贯之。库恩自称“具有可变范畴的康德主义者”有其失误之处。 lexicon (lexicon system) is the most important concept of Kuhn’s later years and is also an alternative to the paradigm. Kuhn discusses taxonomic categories and lexical systems at the linguistic level. He no longer discusses incommensurability from perceptual, methodological and ontological norms and develops non-universality into non-translatability between lexical systems. Kuhn’s explanation of the vocabulary system has a certain degree of ontological qualities that are closely related to his worldview. The evolution from the paradigm to the lexical system indicates that Kuhn’s thought has changed, but its essence is in fact consistent. Kuhn claimed that “Kantians with variable categories” have their mistakes.
