Mind Als Geist In Der Welt Der Kultur: Kultuphilosophie, "Naturalistische" Transzendentalphilosophie Und Die Frage Nach Dem Raum Der Kultur, Sebastian Luft Jan 2018

Mind Als Geist In Der Welt Der Kultur: Kultuphilosophie, "Naturalistische" Transzendentalphilosophie Und Die Frage Nach Dem Raum Der Kultur, Sebastian Luft

Philosophy Faculty Research and Publications

Abstract: Mind as Spirit in the World of Culture. Philosophy of Culture, "Naturalistic" Transcendental Philosophy and the Question of the Space of Culture. In this essay I present Cassirer's philosophy of culture as a special application of Kant's transcendental philosophy. I then compare and contrast it to another tradition, namely the Pittsburgh School, especially McDowell. The starting point here is the Sellarsian concept of the 'Space of reasons', which McDowell expands through his Aristotelian-inspired concept of 'Second nature'. By way of a rather peculiar interpretation of an early interpreter of Cassirer -Howe- I will attempt to bring 'Marburg' and 'Pittsburgh' …
