Abstract

Francisco Varela's extensive body of work spans a wide range of subjects, making it challenging to discern their underlying connections. This issue becomes particularly acute when we compare Varela's early mathematical enquiries with his later phenomenological investigations. I argue that the 'missing link' — the common thread running through Varela's oeuvre — is the act of distinction. When talking about 'distinction', it is important to differentiate between the ready-made distinctions (distinctions as entities) and distinctions in their act of distinguishing (distinctions as processes). My contention is that distinction in this second sense forms the bedrock of Varela's non-dual thought style, the aim of which was to address and supersede the challenges inherent in the dualist (modernist) thought style, especially the infamous two-pronged problem of the bifurcation and disenchantment of nature. The paper delves into Varela's explorations of the act of distinction by tracing its origins in the works of Spencer-Brown, examining its underlying philosophical implications (non-dual onto-epistemology), and exploring its connections to different aspects of his work (form dynamics, autopoiesis, and phenomenology).
