In this paper I argue that Hegel’s treatment of dialectical inferences, in particular of Plato’s dialectics in the Lectures on the History of Philosophy, belongs to the history of the logical rule that, from Gerolamo Cardano to Bertrand Russell, is known as consequentia mirabilis. In 1906 Russell formalises it as follows: and its correspondent positive form as My paper has two parts. First, I show that dialectical inferences, for Hegel, involve sentences of the form and. Hegel, following Plato, stresses that (...) these inferences are das Wunderbare, the marvellous element of dialectical reasoning. In this sense Hegel’s view belongs to the history of CM from a perspective that is both terminological and logical. Second, I stress the peculiarity of Hegel’s CM. In a classical setting, the conditional is admissible and from we can, by CM, derive, and from, by CM, infer. However, in Hegel’s analysis it is evident that we can neither infer from, nor from. Rather, in dialectical inferences what we can vali... (shrink)

Taking as point of departure Hegelrsquo;s early reflections on his historical present, this essay examines the relationship between dialectical reason and the activity of the understanding in generating contradiction. Dialecticmdash;as logic and methodmdash;is Hegelrsquo;s attempt at a philosophical comprehension of the conflicts and the deep changes of his contemporary world. This idea of dialectic as logic of historical transformation guides the development of consciousness in the emPhenomenology of Spirit/em. Since my claim is that the dialectic of consciousness and its capacity (...) of overcoming contradiction are rooted in the historical situation of 1807, the question is raised of what would be the specific problems encountered by consciousness in our contemporary worldmdash;in 2007. What are the challenges posed by our globalized world to a phenomenology of contemporary spirit; and what is the role that contradiction and dialectic play in the understanding of our own historical present?
