International conference: Values in Argumentation – Values of Argumentation

The goal of the conference is to investigate the intricate relationships between argument and value. Given an understanding of argument as articulated reason and a broad conception of values, stretching from individual preferences to deep moral principles and convictions, are these two friends or foes? There is a long tradition of arguing from values, arguing about values and arguing for values: from Perelman’s articulation of the theory of argumentation as “the logic of value judgments” to on-going work in practical philosophy, meta-ethics, applied ethics and value theory in general. The chief problem today is, however, what role argumentation can play in a situation of value pluralism, value conflicts, even deep disagreements. This problem permeates both practical and theoretical reason, given the feeble fact-value distinction. While we have been recommended to respond by resorting to sound argumentation directed to rational “universal audience” (Perelman, Tindale), the reality of the public discourse today seems dominated by appeals to propaganda in order to convert the divided public to one “authoritarian value-system” (Stanley). Is there any way to challenge the simple but ever-stronger uses of arguments supporting that value-system? In any case, we need to re-examine the values in and of argumentation.


These questions, we believe, run deeper than simple semantic ambiguities of the concepts of argument and value. They concern key issues regarding the force of the better argument in the public sphere, the power of values to govern our theoretical and practical reason, and the possible compatibilities and incompatibilities between the two concepts. Accordingly, the focus of the conference is theoretical but not without some practical importance. While the investigation of values and arguments continues among different branches of philosophy – as well as humanities and social sciences in general – the “post-truth society” of today challenges many of the recognised truths. Our aim is to deepen this important current debate.
