Descartes’ Regulae are the first text in which the idea of ​​a universal mathematics is put in connection with algebra. Young Descartes thinks of geometrical figures as a representation of algebraic procedures so as to guarantee its feasibility: i.e., an epistemological foundation of analysis. The young Leibniz starts from a similar problem. He…[Read more]
