The fundamental-ontological approach of Selbstheit and Selbstsein, that is, ipseity and Beingoneself, constitutes rather a complete paradigm-shift in the history of Modern philosophy, and a complete break with the egologies as a whole, since both concepts refer only to “ways of being” or “ways of existing” of Dasein. Insofar as its novelty is acknowledged, the concept of ipseity may thus also be taken as an heuristic tool to investigate the history of philosophy, and especially to reformulate in slightly different terms the problem that was at the centre of the courses on « subjectivity and truth » of the late Foucault
