Radical self-silencing is a particular variety of speech act disablement where the subject silences themselves, whether knowingly or not, because of their own faults or deficiencies. The paper starts with some concrete cases and preparatory comments to help orient and motivate the investigation. It then offers a summary analysis, drawing on a small number of basic concepts to identify its five individually necessary and jointly sufficient conditions and discriminating their two basic forms, ‘internalist’ and ‘externalist’. The paper then explicates and (...) defends what has been proposed, where the most salient and pressing objections concern the use of two basic concepts: ‘uptake’ and ‘silencing’. Finally, the paper gives a longer-term motivation for deepening our understanding of radical self-silencing, what it is and what it implies. (shrink)
