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.
