Cadernos de História e Filosofia da Ciência, Campinas, v. 21, n. 2, p. 353-371, jul./dez. 2011.http://repositorio.bc.ufg.br/handle/ri/19868In this paper, I comment, in the last letters exchanged between Tschirnhaus and Spinoza, the criticism of the latter to Descartes´s notion of extension, and the correlation of this criticism with the spinozistic theory of genetic definition. I propose that such a correlation express, in the physical and logical contexts, the spinozistic solution for the classical problem known as “problem of the One and the Many”, in the ontological context.porAcesso AbertoSpinozaEspinosaDescartesTschirnhausDefinitionExtensionDescartesTschirnhausDefiniçãoExtensãoArtigo
