Pseudoproblems, pseudoquestions, pseudosentences (etc.) constitute an iridescent group of concepts which were prominently used by the Vienna Circle (including Wittgenstein). In the course of an explication this paper presents a compilation of the many different meanings that were given to these expressions. This includes the more prominent Viennese approaches as well as a more recent one by Roy Sorensen. A novel proposal concerning the use ofthe term is made, suggesting that nothing is just a pseudoproblem, but only relative to a (...) certain state of discourse. While the paper follows an explicative methodology, several uses of 'pseudoproblem', including the explicated one, relate pseudoproblemhood to other kinds of analysis. (shrink)
