The article develops and justifies, on the basis of the epistemological argumentation theory, two central pieces of the theory of evaluative argumentation interpretation: 1. criteria for recognizing argument types and 2. rules for adding reasons to create ideal arguments. Ad 1: The criteria for identifying argument types are a selection of essential elements from the definitions of the respective argument types. Ad 2: After presenting the general principles for adding reasons (benevolence, authenticity, immanence, optimization), heuristics are proposed for finding missing (...) reasons, for deductive arguments, e.g., semantic tableaux are suggested.

When can exerting pressure in a public controversy promote reasonable outcomes, and when is it rather a hindrance? We show how negotiation and persuasion dialogue can be intertwined. Then, we examine in what ways one can in a public controversy exert pressure on others through sanctions or rewards. Finally, we discuss from the viewpoints of persuasion and negotiation whether and, if so, how pressure hinders the achievement of a reasonable outcome.
