The negative, by providing the necessary balance to the whole being of the positive, gives beauty to its activity. On the other hand, the positive gives strength to the negative. By its expression of itself, the positive may be said even to create the negative. It is this which is symbolically expressed when it is said that Eve was created from the rib of Adam; that is, the negative created from the positive and actually part of the positive. The negative, then, is derived from the positive and is strengthened by it, and to the positive it returns again; and the positive indeed draws from the negative its positive character. The existence of each depends thus entirely upon the other; and every purpose of each, even its ultimate purpose, is accomplished through the co-operation of both.
