An axiom of philosophical hermeneutics is that questioning has hermeneutic priority. Yet there are many different kinds of questions. Which sort has priority in understanding complete thoughts and for bringing about a fusion of horizons? Speech act theory is one resource for specifying which kind. I first develop the broad notion of questioning in philosophical hermeneutics. Second, I examine aspects of question taxonomies in pedagogy as well as their shortcomings. Third, I turn to the Speech Act approach to questioning and (...) provide a challenge to this theory for adequately addressing what kind takes hermeneutic priority. I propose the category of “suspensives” as the kind of interlocutionary act definitive for questions that have hermeneutic priority. (shrink)
