The instinct of animals or birds for instance warns them very quickly with regard to the presence of some natural enemy whose approach they apprehend through some mysterious sense-impression beyond the analysis of human reason. But when their enemy is the mental intention of a human being they are only too easily tricked.

To take quite a different instance. It may easily happen that while conscience has habitually driven us to a certain course of action against which instinct has never revolted because of its preoccupation with the senses, some sudden flash of intuition reaching us from the hidden substratum of our being changes our whole perspective and gives to conscience itself a completely opposite bias. What these intermittent revelations of intuition certainly do achieve is the preservation in the soul's memory of the clear and deep and free and unfathomable margins of the ultimate mystery, those wavering sea-edges and twilight-shores of our being, which the austere categories of rational logic tend to shut out as if by impenetrable walls.

It remains to consider the attribute of memory. Memory is the name which we give to that intrinsic susceptibility, implying an intrinsic permanence or endurance in the material which displays susceptibility, such as makes it possible for what the soul feels or what the soul creates to write down its own record, so that it can be read at will, or if not "at will," at least can be read, if the proper stimulus or shock be applied.

Memory is not the cause of the soul's concrete identity. The soul's concrete identity is the cause or natural ground of memory. Memory is the "passive-active" power by means of which the concrete identity of the soul grows richer, fuller, more articulate, more complex and more subtle.

In looking back over these eleven attributes of the "soul-monad," what we have to remark is, that two of the number differ radically in their nature from the rest. The attribute of emotion differs from the rest in the sense that it is the living substantial unity or ultimate synthesis in which they all move. It is indeed more than this. For it is the actual "stuff" or "material" out of which they are all, so to speak, "made" or upon which they all, so to speak, inscribe their diverse creations.

The permanent "surface," or identical susceptibility, of this ebbing and flowing stream of emotion is memory; but the emotion itself, divided into the positive and negative "pole," as we say of love and malice, is an actual projection upon the objective universe of the intrinsic "stuff" or psycho-material "substance" of which the substratum of the soul is actually composed. The other aspects of the soul are, so to speak, the various "tongues" of diversely coloured flame with which the soul pierces the "objective mystery"; but the substance of all these flames is one and the same. It is the soul itself, projected upon the plane of material impression; and thus projected, becoming the conflicting duality to which I give the name of "emotion."

The attribute of "will," also, differs radically from the rest; in the sense that "will" is the power which the soul possesses of encouraging or suppressing, re-vivifying or letting fade, all the other attributes of the soul, including that attribute which is the substance and synthesis of them all and which I name "emotion."

In regard to "emotion" the will can do three separate things. It can encourage the emotion of love and suppress that of malice. It can encourage the emotion of malice and suppress that of love. And finally it can use its energy in the effort, an effort which can never be totally successful, to suppress all emotion, of any kind at all.

Man's complex vision then consists, in simple terms, of self-consciousness, reason, taste, imagination, conscience, instinct, sensation, intuition, will, memory, and emotion. These various activities, differentiated clearly enough in their separate energizing, must never be regarded as absolutely separate "faculties," but rather as relatively separated "aspects." Behind all of them and under all of them is the complex vision itself, felt by all of us in rare moments in its creative totality, but constantly being distorted and obscured as one or other of its primal energies invades the appropriate territory of some other.

The complex vision must not be regarded as the mere sum or accumulated agglomeration of all these. It is much more than this. It is more than a mere formal focussing of its own attributes. It is more than a mere logical unity suspended in a vacuum.
