Sensation carried to its extreme limit becomes impersonal; for in its unconscious mechanism personality is devoured. But it does not become impersonal in that magical liberating sense in which the impersonal is an escape, bringing with it a feeling of large, cool, quiet, and unruffled space. It becomes impersonal in a thick, gross, opaque, mechanical manner.
There is brutality and outrage; there is bestiality and obscenity about both pain and pleasure when in their voracious maw they devour the magic of the unfathomable world. Thus it may be noted that most great and heroic souls hold their supreme pain at a distance from them, with a proud gesture of contempt, and go down at the last with their complex vision unruffled and unimpaired. There is indeed a still deeper "final moment" than this; but it is so rare as to be out of the reach of average humanity. I refer to an attitude like that of Jesus upon the cross; in whose mood towards his own suffering there was no element of "pride of will" but only an immense pity for the terrible sensitiveness of all life, and a supreme heightening of the emotion of love towards all life.
It will be noted that in my analysis of "sensation" I have said nothing of what are usually called "the five senses." These senses are obviously the material "feelers" or the gates of material sentiency by which the soul's attribute of sensation feeds itself from the objective world; but they are so penetrated and percolated, through and through, by the other basic activities of the soul, that it is extremely difficult to disentangle from our impressions of sight, of sound, of touch, of taste, and of smell, those interwoven threads of reason, imagination and so forth which so profoundly modify and transmute, even in the art of seeing, hearing, touching, tasting, and smelling, the various manifestations of "the objective mystery" which we apprehend in our sensuous grasp.
By emphasizing the feelings of pleasure and pain as the primary characteristics of the attribute of sensation we are indicating the fact that every sensation we experience carries with it in some perceptible degree or other, the feeling of "well-being" or the feeling of distress.
We now come to consider that dim, obscure, but nevertheless powerful energy, which the universal tradition of language dignifies by the name of "instinct." This "instinct" is the portion of the activity of the soul which works more blindly and less consciously than any other.
The French philosopher Bergson isolates and emphasizes this subterranean activity until it seems to him to hold in its grasp a deeper secret of life than any other energy which man possesses To secure for instinct this primary place in the panorama of life it is necessary to eliminate from the situation that silent witness which we call "the mind" or self-consciousness; that witness which from its invisible watch-tower looks forth upon the whole spectacle. It is necessary to take for granted the long historic stream of evolutionary development. It is necessary to regard this development in its organic totality as the sole reality with which we have to deal.
The invisible mental witness being eliminated, it becomes necessary, if instinct is to be thus made supreme, to regard the appearance of the soul as a mere stage in an evolutionary process, the driving-force of which is the power of instinct itself. Planets and plants, men and animals, are seen in this way to be all dominated by instinct; and instinct is found to be so much the most important element in evolution, that upon it, rather than upon anything else, the whole future of the universe may be said to depend.
Having made this initial plunge into shameless objectivity, having put completely out of court the invisible witness of it all, we find ourselves reduced to regarding this "blind" instinct as the galvanic battery which moves the world. Thus isolated from the other powers of the soul, this mysterious energy, this subterranean driving-force, has to bear the whole weight of everything that happens in space and time. A strange sort of "blindness" must its blindness be, when its devices can supply the place of the most passionate intellectual struggles of the mind!
If it is blind, it gropes its way, in its blindness, through the uttermost gulfs of space and into the nethermost abysses of life. If it is dumb, its silence is the irresistible silence of Fate, the silence of the eternal "Mothers."
But the "instinct" which is one of the basic attributes of the complex vision is not quite such an awe-inspiring thing as this. To raise it into such a position as this there has to be a vigorous suppression, as I have hinted, of many other attributes of the soul. Instinct may be defined as the pressure of obscure creative desire, drawn from the inscrutable recesses of the soul, malleable up to a certain point by reason and will, but beyond that point remaining unconscious, irrational, incalculable, elusive. That it plays an enormous part in the process of life cannot be denied; but the part it plays is not so isolated from consciousness as sometimes has been imagined.
