The use of clarificatory metaphors in argumentative discourse in British Public Bill Committee debates

Abstract In this paper, we aim to explain how metaphors can be employed for clarificatory purposes in British parliamentary debates. These debates typically involve an exchange of arguments concerning complex issues, which more often than not may require clarification. In clarifying something complex, metaphors are often employed in which an unfamiliar and abstract concept is compared to a more familiar and concrete concept. Because the choice of metaphor affects how an issue is understood and reasoned about, discussants may wish to oppose such a metaphor to avoid biased conceptions or even misunderstandings of the issue under discussion. We present a number of cases in which metaphors used for clarificatory purposes are opposed in a British Public Bill Committee debate on the Digital Economy Bill. Our analyses uncover which metaphors are used for clarificatory purposes, to what extent these clarificatory metaphors contribute to furthering the resolution of a debate on the acceptability of legislative proposals, and what consequences opposing such metaphors may have on the continuation of the debate.
