Postphenomenology and the Politics of Sustainable

proper access to the question concerning sustainable technology and I do so in three steps. First, I lay bare how a modern framework that systematically separates facts and instru-ments from values, choices and responsibilities yields no space for engaged decisions and responsible action towards more sustainable societies. In a second step, I elaborate how post-phenomenology’s ‘in-between ’ perspective opens up the possibility of questioning science and technology as an inherent part of our human existence. Building on this, I argue how a ‘normativity of the in-between ’ may be developed around the concept of ‘topical measure’ and which is grounded in the foundationless foundation of postphenomenology’s relational ontology. In a last step, I show how such a ‘topical measure ’ opens up two fields of norma-tive action vis-à-vis the question concerning sustainable technology: one critical, the other empowering. Whereas ‘topical criticism ’ focuses on bringing into the open the powerful sub-politics of science and technology, the field of ‘topical responsibility ’ rather aims at actively assuming responsibility in these political circles. Besides its main interest, which lies in forg-ing a genuine and adequate way into the issue of sustainability, this paper also constitutes an entry into Ihde’s philosophical oeuvre.
