Thought style and thought collective are two well-known concepts from Ludwik Fleck’s theory of science, which he originally formulated in Polish and German. This paper contends that these two concepts cannot be fully understood without a third—Stimmung/nastrój, which is one of the musical metaphors that play an important role in Fleck’s thinking. Because it is most often translated into English as “mood”, Fleck’s musical metaphors are mostly lost in translation, appearing as mere rhetoric. Only if and when we understand Stimmung/nastrój in the musical meaning of attunement, we can fully understand thought collectives, for which Stimmung/nastrój is sine qua non, and thought style, which appears if and when a collective turns out to be an enduring and not a momentary one.

思想风格和思想集体是路德维克·弗莱克（Ludwik Fleck）最初用波兰语和德语提出的科学理论中的两个著名概念。本文认为，如果没有第三个概念-Stimmung / nastrój，就无法完全理解这两个概念，Stimmung / nastrój是在Fleck思维中起重要作用的音乐隐喻之一。由于弗勒克的音乐隐喻最常被翻译为“心情”，因此在翻译中大部分都被遗忘了，仅表现为修辞。只有并且当我们在调性的音乐意义上理解Stimmung /nastrój时，我们才能完全理解思想集中的人，其中Stimmung / nastrój是必要的，以及思想风格，当集体最终成为持久而不是短暂的集体时，就会出现这种思想。
