Giacomo LEOPARDI’S “L’INFINITO” and Decision Limit Problems Arturo Tozzi When an observer stares out at a horizon that is miles away, the sight of an object caught in the middle allows her mind to imagine the occurrence of the infinity beyond the edge. According to this psychological account of infinity, put forward by Giacomo Leopardi in his masterpiece “L’infinito”, a restricted view is required for our imagination to work properly: in absence of a bounded object with edges, our mind is unable to think about infinity. Here we show how Leopardi’s account is correlated with recent topological approaches to closed curves, and with long-lasting medieval debates on decision limit problems: when a boat disappears over the horizon, what is the instant (o the minimum spatial range) of change between visibility and non visibility? viXra:1912.0474
