In his later work »Philosophical Investigations«, Ludwig Wittgenstein focused his musings on a grammatical description of our everyday actions. This distancing from essentialist, Aristotelian definitions of beings has not lost any of its power today. With Habermas, the »world-shaping acts« (weltkonstituierende Leistungen) were passed on to »grammatical structures« in the 20th century. Thus, new light is shed on the subject's talk of itself: it is composed in a grammatical way, with knowledge of the constant mutability of those rule systems that become established through grammatical standards. For the very first time, this volume describes the category of grammatical subjectivity as a broadening of the frame of reference in which people speak of themselves: regarding topics such as knowledge, ethics, politics, the circumstances of modernity, or the notion of cogito.
