Prejudices and Horizons: G. F. Meier's Vernunftlehre and its Relation to Kant

The object of G. F. Meier's Vernunftlehre and its abridgement for courses, the Auszug aus der Vernunftlehre, does not consist exclusively in the elaboration of the formal aspects of logic, but rather in the individuation of the elements of thought and language, which make human understanding possible. Instead of limiting himself to formal truth, Meier investigates the realms of epistemic, aesthetic, and historic truths, of horizons, and prejudices. Kant used both Meier's Vernunftlehre and its Auszug for about forty years in his logic-lectures. Kant's Logik, and also his Kritik der reinen Vernunft, were thus strongly influenced by Meier.
