A survey of the entire field of human existence presents to the ordinary consciousness of mankind the widest variety of interests and means of satisfaction. There is, in the first instance, the complex system of purely physical necessities, to the satisfaction of which the whole economy of industrial enterprise, through all its complicated tissue of commerce, merchandize, and technical crafts, is actively pursued. If we raise the level of our review to a more spiritual range, we are confronted with the world where rights are established and enforced, the world of legislative enactment, family life, division of social classes, in a word, the concrete living organism of the State. And more than this, there is the religious want, which asserts itself in the hearts of particular men and women, and finds its satisfaction in the life of a church. Finally, there is the many-sided and intricately specialized activity of scientific research, the organized effort to integrate all knowledge, and the comprehension which that knowledge implies, in one all-embracing system. Within this latter are comprised the activities of the fine arts, the interest, that is to say, in beauty, and which derives its spiritual nutriment in the realization of that beauty in plastic shapes. (_d_) The question becomes inevitable how far a spiritual want of this kind is bound up as a necessary element in the life of man and his world-history. In the first instance these two spheres[180] appear simply as immediate factors of our entire survey. It is, however, the requirement of philosophy to probe more deeply into that which binds them as essential and necessarily interacting constituents of one organic whole. For on closer inspection it will be found that they do not stand in relation to one another on the mere basis of utility; rather we shall discover that only through the one we shall fully comprehend the other. In other words, the one circle overlaps the other, in the sense that the higher forms of its activity are found to be a part of the other; and that which is of less value in its own province is lifted into a finer atmosphere; and what had failed to free itself from its original bounds is now enlarged to liberty through the profounder satisfaction it receives in the widening of the range of its interests[181]. And it is this which makes clear the necessity of the ideal bond.
