 In 1812 Jacobi retired and, aided by his disciples J. F. Köppen and C. J. F. Roth, began the preparation of his collected works (Jacobi, 1812–25). Since the turn of the century, he had begun to attract to his side such younger figures as F. D. E. Schleiermacher, J.  F. Fries, and F. Bouterwek — newly established academics whose thought he had inspired but who, in turn, influenced his final definition of the nature of reason. They all shared a scientific positivism which they combined with a contrasting moral/religious positivism — this latter based on the assumption that higher values and the reality of divine things can be intuitively assessed by way of feeling. This younger generation helped to popularize some of Jacobi’s ideas and attitudes in the nineteenth century. Ironically, despite his life long opposition to Roman Catholicism, Jacobi exercised considerable influence in some German Catholic theological circles (Weindel, 1950).
