Appunti sulla ricezione del De brutorum loquela: il caso di Florent Schuyl

Abstract: in 1603 the anatomist Fabrici of Aquapendente published his De brutorum loquela, a treatise on animal language and cognition, in which he demonstrated that the presence of an articulated language in non-human animals allows to claim their rationality and to read the difference between them and human beings from a gradualistic point of view. Unfortunately, the emergence of the anti-gradualistic cartesian theory of beast-machine didn’t allow Fabrici’s theories to spread adequately. therefore, Fabrici’s legacy became a historiographical problem: has Fabrici’s work been forgotten during the modern age? An unexpected quotation of the De brutorum loquela in the Preface to Descartes’ Treatise on man (1662) allows us to point out some hypothesis on this question.
