## Abstract

Based on the theory of dialectical structures, I review the concept of degree of justification of a partial position a proponent may hold in a controversial debate. The formal concept of degree of justification dovetails with our pre-theoretic intuitions about a thesis’ strength of justification. The central claim I am going to defend in this chapter maintains that degrees of justification, as defined within the theory of dialectical structures, correlate with a proponent position’s verisimilitude. I vindicate this thesis with the results of simulations of controversial argumentation.
