The final chapter of this volume provides several points of further theoretical elaborations, which, important for our overall argument, would have unduly cluttered the various chapters. It starts by considering how challenges to common sense arise from various types of dissent or deviance including children, homecomers, newcomers, strangers, foreigners, robots or aliens. It proceeds to discuss why and how object-relations and 'inter-objectivity' thought, noted by various scholars, have not received sufficient attention in psychological scholarship and certainly not in relation to influence by artefacts. The chapter lays out the theoretical foundations for such a broadening of scope. The chapter then proceeds to discuss the historically curious dominance of dual-process models over single-process alternatives. The excursions conclude by revisiting the debates concerning the authority of science in Milgram's obedience studies in light of a broader understanding of autonomy, tyranny, argumentation, legality and violence.
