| Abstract: | Among normative models for democracy, the Deliberative model suggests that public policy decisions should be made only following rational, public deliberation of alternative courses of action. We argue that such a model is particularly appropriate for the assessment of environmental and health risks of new substances and technologies, and for the development of appropriate regulatory responses. To give operational effect to these ideas, we propose a dialectical argumentation formalism for an intelligent system within which deliberative debates about risk and regulation can be conducted. Our formalism draws on various philosophies of argumentation, scientific and moral discourse, and communicative action, due to Toulmin, Pera, Alexy and Habermas. |
