The purpose of this paper is to present the philosophical questions that revolve around the ordinary Schopenhauerian accusation of quackery against his opponents. The study of these satellite-questions shows that quackery can be understood as a philosophical problem and not merely an offense empty of theoretical relevance, as commonly understood. They can be summarized as aesthetic or rhetorical questions, because they problematize the style of the philosophical text, its use and its communicative function. Close to the pedant and the sophist, the charlatan is one who abuses obscurity because of his distancing from concreteness by an option for abstract writing.The purpose of this paper is to present the philosophical questions that revolve around the ordinary Schopenhauerian accusation of quackery against his opponents.

O estudo dessas questões-satélites mostra que o charlatanismo pode ser compreendido como um problema filosófico e não mero xingamento vazio de relevância teórica, como se entende comumente. Elas podem ser resumidas como questões estéticas ou retóricas, porque problematizam o estilo do texto filosófico, o seu uso e sua função comunicativa. Próximo do pedante e do sofista, o charlatão é aquele que abusa da obscuridade por conta de seu afastamento da concretude por uma opção pela escrita abstrata.
