 Philosophy, at least in Moulton’s (1983) context of late twentieth century Anglo-American or “analytic” philosophy, may be so permeated by the combination of adversarial arguing and deductive logic that the Adversary Method operates as a disciplinary “paradigm”. Moulton argues that this “paradigm” for philosophy demands aggressive opposition to other people’s opinions, in the same way that Thomas Kuhn observed that mature scientific disciplines demand adherence to an overarching theory, an ideal, and a practice that together constitute a cultural paradigm. Philosophers’ technique of aiming to falsify each other’s claims reflects Karl Popper’s epistemology but adversarial reasoning in philosophy has taken many different forms and traces back at least to Aristotle. Descartes and Kant shifted the normative focus of the study of logic from dialogue to individual cognition, and the logic of opposition became internalized (Dutilh Novaes 2011, 2015). Yet, arguing as a dialogical form of reasoning retains the oppositional dynamic.
