The reflections herein gathered differ from the mental forms of the conventional Brazilian, a meaning in which they exert a pedagogical and therapeutic function: pedagogical because they explicit certain littleness of the Brazilian mental means, exalt values better than the trivial, clarify situation; that is, teach the reader how to interpret a given portion of the world and life with more lucidity. Therapeutic because, as he censures the censurable, he exalts the meritorious, denounces usages; Post Scriptum is virtually capable of inducing its readers to review their values and sub-values, behaviors and sub-behaviors and, therefore, contribute to (if you will pardon the expression) “build a better world”.
