The ingenious thought of Anton Günther (1783–1863) is rarely mentioned in the annals of nineteenth-century philosophy. However, in the eyes of his contemporaries, Günther belonged to the key thinkers of his age on par with Kant, Fichte, Hegel, and Schelling. Günther was an original writer yet he left many of his insights undeveloped or ambiguously formulated. As a flamboyant and popular debater, he attacked the most influential philosophers of his time. His attacks were aimed especially at what he termed the (...) unavoidable pantheism of these thinkers, a pantheism Günther often identified with monism. Monism, semi-monism, pantheism, and semi-pantheism are recurring charges of Günther against many influential thinkers, including even Descartes, whose thought Günther considered otherwise epoch-making. Based on a reformed Cartesianism, Günther elaborated his antidote he termed dualism. Yet Güntherian dualism turns out to be a synthesis properly termed organicism. On such a basis, Günther carried out a heroic attempt to transcend the horizon of traditional views and open the vista of an I-centered philosophy built on the universal notion of revelation. By re-reading this Bohemia-born thinker, one can have a better understanding of the scope and influence of what we term Austrian Philosophy. (shrink)
