With the Kantian criticism of the pseudo-science of theology Jacobi had in one way no fault to find. That reasoning by its demonstration cannot find out God, was to him an axiomatic belief. But the 'man of feeling' felt uneasy at the trenchant methods of the Königsberg man of logic. He seemed to see the world of men and things passing under Kant's manipulation into a mere collection of phenomena and ideas of the mind. Still more was he sensible to the loss of his God. That surrogate of an argument for theism which Kant seemed to offer in the implications of the Moral Law did not give what Jacobi wanted. Mere morality is a cold and mechanical principle--he thinks--compared with that infinite life and love which we deem we have in God. The son of man, he felt, was, in virtue of an indwelling genius of conscience, supreme over the moral law: how much more, then, the Absolute and Eternal on a higher grade of being than its mechanical regularities! If the way of reasoning will not carry us to the Absolute, still less (and that is whither Jacobi wishes to reach) to God, there must be another way: for something in him, which may be called Faith or Feeling, Spiritual Sense or Reason, proclaims itself certain of the reality both of God and Nature. There _is_ an objective reality--outside and beyond him--yet somehow to be reached by a daring leap,--whereby, out of sheer force of will, he, shutting his eyes to the temporal and the mechanical, finds himself carried over the dividing gulf into the land of eternal life and love.
