At the present paper it will be pursued to give account of how discursiveness is configured in the works of Nietzsche and Freud around the notion of life from a Freudian concept, that of underpinning. From the same, the particular discursive field relative to the vital will be characterized ―both in Freud and Nietzsche― as hybrid field ―meaning, a field that does not subscribe to any particular epistemological canon― thus giving account that innovation is produced not only when thinking the (...) very concept, but also when constructing the discourse.
