In this short discussion note, I cast doubt upon the common view that social groups persist throughout changes in their membership, by virtue of the maintenance of their structure and/or function. I offer two counterexamples, and consider two possible responses to a natural objection to them, neither of which support the view that it is a metaphysical truth that social groups persist through changes in their membership, or persist by virtue of the maintenance of their structure and/or function.

在这篇简短的讨论笔记中，我对以下共同观点表示怀疑：社会团体由于其结构和/或功能的维持而在其成员变动中始终存在。我提供了两个反例，并考虑了对它们的自然异议的两种可能的应对方式，它们都不支持这样一个观点，即社会群体通过其成员资格的改变而坚持下去，或者由于维持其结构和地位而坚持下来是一种形而上的真理。 /或功能。
