Hegel gave many lectures in logic at Berlin University between 1818 and his untimely death in 1831. Edited posthumously by Hegel’s son, Karl, these lectures were published in German in 2001 and now appear in English in Clark Butler’s translation. Because they were delivered orally, Lectures on Logic is more approachable and colloquial than much of Hegel’s formal philosophy. The lectures provide important insight into Hegel’s science of logic, dialectical method, and symbolic logic. Readers at all levels will find a mature and particularly clear presentation of Hegel’s systematic philosophical vision.
