Such accentuation of autonomy in life and morality, might seem to exalt man unduly, and to inspire him with self-conscious pride. But we have already guarded ourselves against such misapprehension. We have seen that every undertaking possible to the individual lies within a sustaining and impelling movement of the whole. The recognition of morality is therefore not a matter of personal option or caprice. The life of the whole operates in the individual; but, on the other hand, his decision influences the whole of reality in the direction of progress or retrogression. In this way the conception of duty arises, in which the whole of life, the whole of the cosmic movement formulates a claim on us. Kant rightly pointed out that duty cannot come to us from without, but must proceed from our own being. This can only be the case if our being experiences an inner gradation. A spiritual world speaks within us, not as something alien, but in union with our own innermost being, as the depth of our own soul. The idea of duty is necessary in proportion to the consciousness and recognition of the difference between man as he is, and the inner world which corresponds to his innermost being. Wherever this consciousness grows dim, there morality speedily experiences an inner weakening. Duty is the salt of life. Where it is lacking, life, however brilliant externally, becomes inwardly tame and insipid, while on the other hand, duty can impart inner greatness and dignity to what appears small and insignificant. But as we do not wish the presence of salt to be everywhere perceptible, so also the idea of duty must not always force itself on our consciousness, but must be a latent power in our soul and life, lifting us above all that is arbitrary and capricious. We must take duty up into our inner being, and not place it there as something alien or hostile. Moral life can quite well unite earnestness and joy, reverence and love--earnestness and reverence towards the superior majesty of a higher power operative to us, joy and love arising from the mighty presence of this higher power within us. * * * * *
