Abstract
We have studied the veritistic dynamics ofrandom argumentation (with and without explicitbackground knowledge) in the previous chapters. In this chapter, we will drop the assumption that arguments are introduced randomly into the debate and suppose that proponents put forward arguments in line with a specific argumentation strategy they pursue. In close analogy to our investigation in Chap. 6, we distinguish and study four argumentation rules:fortify,attack,convert, andundercut. We simulate debates with two proponents and examine how thetruth-conduciveness of controversial argumentation depends on the strategies chosen by the proponents. In the next chapter, we will extend this analysis to multiproponent debates.

Notes
- 1.
It is because of this fallback option to random argumentation that some verisimilitude evolutions in Figs. 13.1–13.6, such as fortify–fortify in Fig. 13.1, display a sudden and sharp upward turn at densities close to 0.8. This sudden rise indicates the point where there exist typically no more arguments that can be introduced in line with the corresponding strategy and where randomly constructed arguments spawn new inferential relations.
- 2.
That is, the constellation undercut–rule1 causes mean verisimilitude to increase at least as much as (and often substantially more than) any other constellation rule2–rule1 does, for arbitrary rules rule1 and rule2.
