Authority Argument Schemes,Types, and Critical Questions

Authority arguments generate support for claims by appealing to an agent’s authority status, rather than to reasons independent of it. With few exceptions, the current literature on argument schemes acknowledges two basic authority types. The epistemic type grounds in knowledge, the deontic type grounds in power. We review how historically earlier scholarship acknowledged an attractiveness-based and a majority-based authority type as equally basic type. Crossing these with basic speech act types thus yields authority argument sub-schemes. Focusing on the epistemic-assertive sub-scheme (‘an epistemic authority A_E asserts a proposition P’), we apply a meta-level approach to specifying critical questions. Results improve the evaluation of this sub-scheme and show how similar improvements are obtainable for other schemes.
