Ernst Julius Wilhelm Schuppe, the German philosopher, was born in Brieg, Silesia. He studied at the universities of Breslau, Bonn, and Berlin, and he took his doctorate at Berlin in 1860. He taught at grammar schools in Silesia and then held a chair of philosophy at the University of Greifswald from 1873 to 1910.

Epistemology

In his main work, Erkenntnistheoretische Logik (Bonn, 1878), largely anticipated by his earlier book Das menschliche Denken (Berlin, 1870) and summarized in his later Grundriss der Erkenntnistheorie und Logik (Berlin, 1894; 2nd ed., Berlin, 1910), Schuppe was concerned with the epistemological bases of knowledge generally and of logic in particular. Schuppe held that a theory of knowledge should avoid hypotheses such as the transcendent reality postulated by realists and metaphysicians, but that it should equally avoid one-sided objective or subjective foundations of knowledge, whether materialist, positivist, or idealist.
