["Chemistry of Concepts”and “Historical Sense”. On Philosophical Concept Formation]

"Chemistry of Concepts" and "Historical Sense". On Philosophical Concept Formation. The question concerning concepts and their relations to objects and words has had a long and controversial history. Recently, it is challenged by an anew turn towards objects and an emphasized object-oriented ontology. The article argues that one reason for this is the reduction of concepts towards pure rational constructions and offers arguments for alternative understandings. In this context, the article proposes a re-reading of Nietzsche's particular approach and shows that Nietzsche's thought is decisively shaped by the sciences of his time, especially physiology and chemistry. Before the background of the recent increase in research interest on Nietzsche and the sciences the article examines place and function of the sciences related to the genealogy and justification of concepts. Opposing a strong naturalist reading it makes a plea for understanding Nietzsche's epistemological critique concerning concepts systematically as a triple one: philological, physiological, and historical.
