Knowledge or intellect, therefore, is only the surrogate of that more intimate unity of feeling or will which is the underlying reality - the principle of all existence, the essence of all manifestations, inorganic and organic. And the perfection of reason is attained when man has transcended those limits of individuation in which his knowledge at first presents him to himself, when by art he has risen from single objects to universal types, and by suffering and sacrifice has penetrated to that innermost sanctuary where the euthanasia of consciousness is reached - the blessedness of eternal repose.
