Abstract
_Nicolai Hartmann and Alexius Meinong on Apriority and Causality. Notes on the Correspondence_
The article offers a critical reading of the nine letters composing the correspondence exchanged by Alexius Meinong (1853-1920) and Nicolai Hartmann (1882-1950) in 1915 and 1918-1920. The author explores the main contents of the correspondence, through a chronological-thematic analysis. The letters of 1915 are eminently dedicated to a discussion of the gnoseology-ontology relationship. Here, the author focuses (1.1) on the relationship between reality and knowledge and (1.2) on that between a priori and cognitive principles. The analysis (2) of the 1918-1920 correspondence concludes the article, engaging in the theme of the law of causality. Different in the philosophical background and argumentative style, the late Meinong and the young Hartmann find a field of dialogue that appears not lacking in consequences on the philosophical evolution of the latter.
