Barbara Skarga's book 'Tozsamosc i róznica. Eseje metafizyczne' (Identity and Difference. Metaphysical essays, 1997) is a book of excellence - a fundamental work that engages in the crucial philosophical debate. In this paper, the author sketches one of the points of the discussion of this work that concerns the question of the Self, or - in another philosophical idiom - the question of the contemporary crisis of subjectivity. B. Skarga brings out this problem in three perspectives: eidetic, teleological and existential. She establishes at the same time incommensurability of the contemporary 'theories' that announce the demise of the subject to her own position that grows out of the 'experience' of the subject - of its multifarious affirmation. This incommensurability is an occasion to pose several questions, such as 'linguistic' articulation of experience or philosophical nature of B. Skarga's project, that are supposed to challenge the consistency of the incommensurability as stated in the book. The aurho is of the opinion that B. Skarga, by entering the domain of metaphysical research, is forced to leave territories where a simple principle of opposition between 'theory and experience' is at work.
