The term "Frankfurt School" is an informal term used to designate the thinkers affiliated with the Institute for Social Research or influenced by them—it is not the title of any institution and the main thinkers of the Frankfurt School did not use the term to refer to themselves.
“法兰克福学派”是一个非正式术语，用来指称隶属于社会研究所或受其影响的思想家——不是任何机构的名称，法兰克福学派的主要思想家也没有使用这个术语来指称他们自己。
