VI. The Age of Kant and Goethe

Leibniz's thoughts tended in the opposite direction. The human soul is, for him, the self dependent monad, strictly closed off in itself. But this monad experiences only what it contains within itself; the world order, which presents itself “from without, as it were,” is only a delusion. Behind it lies the true world, which consists only of monads, the order of which is the predetermined (pre-established) harmony that does not show itself to the outer observation. This world conception leaves its self-dependence to the human soul, the self-dependent existence in the universe, its freedom and hope for an eternal significance in the world's evolution. If, however, it means to remain consistent with its basic principle, it cannot avoid maintaining that everything known by the soul is only the soul itself, that it is incapable of going outside the self-conscious ego and that the universe cannot become revealed to the soul in its truth from without.
