14h00: TURING AND FIBONACCI: FORM AND FUNCTION OF MATHEMATICS INTO THE BIOLOGICAL SCIENCES
By reviewing some mathematical models, the use of mathematics in the biological science is discussed. In particular it is shown that same mathematical forms can have different functions from both the biological and the philosophical point of view.

15h45: Pause

16h00: VAGUENESS, KANT AND TOPOLOGY
An original approach to vagueness is proposed. It is characterized by two features. The first one is philosophical: I move along a Kantian approach emphasizing the knowing subject's conceptual framework. The second one is formal: to face vagueness the introduction of a formalism based on topology is suggested. I show that the Kantian and the topological features joined together allow us an atypical, but fruitful, way of considering vagueness.
