The central supposition of the sceptical controversy regarding rationality in the theory of argumentation is that either there are universal standards against which the reasonableness of arguments can be evaluate or, conversely, that there are no determinate standards against which arguments can be evaluated, and hence no methods by which disputes can be rationally resolved. The paper argues that the basic terms of this debate are erroneously defined and that there is a middle path in this sceptical controversy. The paper (...) adopts the later Wittgensteinian approach to language and applies it to the concept of rationality. Furthermore, it maintains that the search for universal standards of reasonableness in theories of argumentation is likely to come to naught, and that, nonetheless, there are discoverable methods by which arguments are evaluated, facts constituted, and disputes resolved.

The French philosopher and intellectual historian Pierre Hadot (1922-2010) is known primarily for his conception of philosophy as spiritual exercise, which was an essential reference for the later Foucault. An aspect of his work that has received less attention is a set of methodological reflections on intellectual history and on the relationship between philosophy and history. Hadot was trained initially as a philosopher and was interested in existentialism as well as in the convergence between philosophy and poetry. Yet he chose (...) to become a historian of philosophy and produced extensive philological work on neo-Platonism and ancient philosophy in general. He found a philosophical rationale for this shift in his encounter with Wittgenstein's philosophy in the mid-1950s (Hadot was one of Wittgenstein's earliest French readers and interpreters). For Hadot, ancient philosophy must be understood as a series of language games, and each language game must be situated within the concrete conditions in which it happened. The reference to Wittgenstein therefore supports a strongly contextualist and historicist stance. It also supports its exact opposite: presentist appropriations of ancient texts are entirely legitimate, and they are the only way ancient philosophy can be existentially meaningful to us. Hadot addresses the contradiction by embracing it fully and claiming that his own practice aims at a coincidence of opposites (a concept borrowed from the Heraclitean tradition). For Hadot the fullest and truest way of doing philosophy is to be a philosopher and a historian at the same time. (shrink)
