Françoise #Dastur: "We must ask ourselves what constitutes the essence of theoretical science itself. #Heidegger shows in his lecture [of 1919] that the experience of the "thing", of what we call "reality", presupposes the objectification of life and a devitalisation of the living experience, in the sense of an eradication of the interpretation immediately given to the environment. The result of this process of devitalisation and disinterpretation is nothing other than the real in the form of the #data (Gegebenheit) which is in fact a false immediacy, a theoretical construct."
