Abstract

Johann Friedrich Ludwig Schröder (1774-1845 ) was born in Germany but moved to Holland at the age of 13. After studying at Halle he joined the Kantian movement in Amsterdam as an active member, cooperating with Paulus van Hemert and contributing articles to his Kantian magazine. During his professional career as a marine instructor (1803-11 ), however, he became increasingly critical of Kantianism. As professor of mathematics, physics and philosophy at the University of Utrecht (1816-44) he traded in his former Kantianism for a variant of the common sense philosophy then in favour in the Netherlands. He now regarded Kantianism as a form of scepticism. Accordingly, in his major work, the Contnbution to a Critique of the Truth of Human Knowledge, he propounds an anti-sceptical doctrine of such ‘basic truths’ as are founded on the immediate relevation of our consciousness. Schröder also attempts to reduce the Kantian doctrine of the noumenon to an inconsistent set of propositions, by showing them to be antinomies in the Kantian sense of the term, even using Kant's own dialectical method in proving their contradictoriness ; these contradictory propositions he calls the 'antinomies of the Kantian philosophy'. In a minor work, The Sign Relation as the Basis of Human Knowledge (translated freely), we find reminiscences of Thomas Reid's Inquiry into the Human Mind: of the doctrine of sensations suggesting our conceptions of things, of causes being the signs of their effects, of 'the natural language of mankind'. Schröder, in developing these ideas in his own way, presents the sign relation as being fundamental to the construction of our knowledge of both nature and the human soul. Only by taking one thing as the ‘sign’ (signal, symbol, symptom, index, expression, picture, representation etc.) of another can we attain a conception of the world as a coherent whole. Our perception of this relation is partly a matter of innate capacities, partly the result of acquired skill
