A psicanálise é uma ciência e o discurso analítico é uma práxis?

I propose in this article that psychoanalysis is, in its absolute sense, within the field of science, since with topology, mathemes, formulas of sexualization and borromean knots, Lacan insisted on separating these structures of the meaning. I make a distinction between science and praxis, admitting that psychoanalysis is divided between one and other. However, if psychoanalysis is - in the absolute sense - an experience that leads to a meaningless existence, we better reexamine this distinction.
