Neste artigo examinamos a concepção filosófica do suicídio em Schopenhauer. Mostramos que a razão fundamental pela qual Schopenhauer rejeita o suicídio está intimamente ligada ao fundamento da sua metafísica. Explicamos suas diferenças face às rejeições tradicionais do suicídio, visto que Schopenhauer considera o suicídio um erro mas não um crime, e quais são os casos nos quais o suicídio pode ser aceito.

For several years I have been developing a general theory of logics that I have called Universal Logic. In this article I will try to describe how I was led to this theory and how I have progressively conceived it, starting my researches about ten years ago in Paris in paraconsistent logic and the broadening my horizons, pursuing my researches in Brazil, Poland and the USA.

Using methods of abstract logic and the theory of valuation, we prove that there is no paraconsistent negation obeying the law of double negation and such that $\neg(a\wedge\neg a)$ is a theorem which can be algebraized by a technique similar to the Tarski-Lindenbaum technique.
