The present article purports to answer the old question of whether the concept (and the method) of Hegelian dialectic can be clarified. Three arguments are advanced in defence of the claim that Hegel's conception is not in fact intelligible. The first argument shows that dialectical negation leads to an infinite regress. The second argument analyses Hegel's claim that the dialectical method yields a positive result and demonstrates that this claim remains completely unsubstantiated and unsubstantiable. The third argument comes to the (...) conclusion that Hegelian dialectic cannot pretend to be an acceptable explication of the “intuitive” understanding of negation. An APPENDIX examines critically a new attempt by D. Wandschneider of reconstructing the first steps of Hegelian dialectical logic by displaying “antinomic structures” and by employing (at least to a limited extent) the techniques of formal logic.
