Il problema del mondo nei primi corsi friburghesi di Martin Heidegger

My research concerns Martin Heidegger’s early lectures, held in Freiburg 1919-1923. These years represent for Heidegger an intense period of phenomenological experimentation, based on new fields for Phenomenology, as the one represented by the notion of «Lifeworld» (die Lebenswelt) and generally all phenomenological questions involved in the concept of World and Environment, frequently examined by Heidegger in those years. My statement is that the problem of World is one of the most important impulse for Heidegger in elaborating his own phenomenological philosophy that will lead him up to Being and Time.
