This paper consists in the Spanish translation of a manuscript by Franz Brentano, where he deals with “The Method of Study of Aristotle and, More Generally, the Method of Historical Research in Philosophical Field”. In these pages, Brentano challenges the Aristotelian studies of his time by criticizing the approach followed by E. Zeller and other scholars. Meanwhile, he suggests some hermeneutical rules in order to interpret Aristotle in the right way. The core of his proposal is the use of philosophical (...) hermeneutics, that is, the interpreter should philosophize following the Aristotelian arguments, like the Peripatetics used to do. In his introduction to the text by Brentano, the Spanish translator also recommends a new chronology for the manuscript, i.e. not much later than 1883.
