ABSTRACT
The idea of the history of philosophy as the lingua franca of thought would be a matter not only of mere communication, but also of the production of ideas. It is true that Wilfrid Sellars's reconstructions are very often ideal-typical rather than historical, but it is also true that he was working at a time when specialization had yet to produce its disruptive effects. The subsequent fortunes of the historiography on Leibniz help us to understand this point: up until the Sixties, works published on Leibniz were relatively few and often unsatisfactory. In Sellars's interpretation of Leibniz we can identify two quite distinct, albeit internally linked, fields of inquiry: the first focuses on some technical questions of logic and philosophy of language; the second on some broader questions of epistemology, ontology and history of philosophy. Leibniz's thesis of the inesse is supported by several considerations regarding the nature of truth.
