In his works from maturity, Honoré de Balzac tries to formulate a philosophical system describing the role of the thought and its impact on human life. Those reflections originate already in his early works since 1818, in his philosophical notes, and later in the novels from the 1820s, as well as in other texts. His opinions develop in a certain “economy of thought” through which are expressed dialectics of thought, will and vital energy.
