The outdated part nine. 1 on similar examine has been up to date and extended right into a complete bankruptcy, whereas the remainder of the previous bankruptcy is now in revised shape in bankruptcy 10. This bankruptcy additionally comprises new contributions, a close dialogue of Gordon's Pleadings online game, and a basic description of a multi-Iayered total view at the constitution of argu mentation, comprising a logieal, dialectical, procedural and strategie layer. ultimately, within the revised end i've got paid extra cognizance to the relevance of my investigations for criminal philosophy and argumentation theory.
