The truth is that in this ultimate revelation of the complex vision we are confronted with an inevitable triad, or trinity, of primordial aspects. We are compelled to think of a plurality of living souls of which our own is one; of certain ideal companions of all souls whose vision gives to our vision its objective value; and of an external universe which is the creation of this vision. What the complex vision indicates, therefore, is a system of things which has a monistic aspect, for there is only one space and only one succession of time; a pluralistic aspect, for the system of things gives birth continually to innumerable individual souls; and a dualistic aspect, for the universe itself is created by the struggle between love and malice. What the complex vision does not indicate is any ultimate principle which reduces this complex system of things to the unbroken mass of one integral unity. The nearest approach to such an unbroken, integral unity is to be found in that indefinable "medium" which makes it possible for the innumerable souls which compose the universe to communicate with one another and with their invisible pre-existent companions. It is only the existence of this indefinable medium which makes it possible for us to speak of a universe at all. For this medium is the objective ground, or basis, so to say, from the midst of which each individual vision creates its own universe, always appealing as it does so to that objective standard or pattern of truth offered by the vision of man's invisible companions. What we roughly and loosely call "the universe" or "nature" is therefore an accumulated projection or creation of all the souls which exist, held together by this pervading medium which enables them to communicate with one another. In this eternal process of creating the universe by their united visions, all these souls must inevitably appeal, consciously or unconsciously, to the vision of their pre-existent companions.
