This chapter shows that the antinomies of pure reason present an analogy between the critique and a civil trial in which reason in the narrow sense is challenged to prove that it can legitimately possess and use its ideas. In reconstructing the different parts of this image, Møller suggests reading the tribunal image as a second-order model of evaluation of judgements. In order to achieve this aim, Møller inspects the different roles and procedures mentioned in the juridical metaphors to see how they fit the different procedures in the antinomies. The chapter untangles the notions of the tribunal itself, the trial, the witnesses, the audience and the verdict. The image of the reader as judge is considered in its intellectual historical context, which shows an affinity between Kant’s use of this image and the project of enlightenment.
