This book is composed of texts that were written and evaluated as partial requisites for the conclusion of the Master's Degree in Philosophy, and the Specialization in Clinical Psychology, both held at the University of Caxias do Sul. As an exception, some small productions are presented (four last writings) derived from the work in cartels carried out at CAPPES (Clinica de Atendimento Psicanalítico/Psiquiátrico e Estudos).
