This article presents a central cultural areopagus of French-speaking Switzerland from1906 to 1939, the Société romande de philosophie (SRP), nearly unknown to philosophersand historians alike, a blind spot of philosophy in Romandie. The spontaneous readingphilosophers can make of their past as a history of philosophical theories ensues in aretrospective disciplinary unit attributed to philosophy. Yet, contrary to that view, weshow that, in Romandie, this past was structured both by adisciplinary pluralismsup-ported by numerous cantonal, intercantonal and international networks, and by a genuineunity around certain values other than the criterion of discipline. As a result, identity—and therefore belonging—was not basedon philosophyas a discipline, but on disciplinaryplurality as much as on the very sharing of many values. Those ranged from intellectualfraternity to taking the divine seriously, from the celebration of the homeland to feder-alism and the tolerance vis-à-vis divergent ideas, from the praise of living together to thesearch of the truth.
