symbolic knowledge), as is paradigmatically the case of mathematics, by operating with symbols according to rules – even when these symbols do not represent anything? This problem presented itself very early in Husserl's philosophical life and was a dominant factor in the development of his thought. From the first to the last work he published the task of clarifying the sense and delimitating the scope of symbolization and formalization in science and mathematics was one of Husserl's major concerns. In this paper I want to show how Husserl dealt with the problem of symbolic knowledge in mathematics, and the central role it played in his philosophical development." /> Beyond Leibniz - Da Silva Jairo José | sdvig press
