When we leave the question as to the existence of conscience, and enquire what the precise and particular "command" of conscience may be in any individual case, we approach the edge of an altogether different problem.
The particular message or command of conscience is bound to differ in a thousand ways in the cases of different personalities. Only in its ultimate essence it cannot differ. Because, in its ultimate essence, the conscience of every individual is confronted by that eternal duality of love and malice which is the universal contradiction at the basis of every living soul.
But short of this there is room for an infinite variety of "categorical imperatives." The conscience of one personality is able to accept as its "good" the very same thing that another personality is compelled to regard as its "evil." Indeed it is conceivable that a moment might arise in the history of the race when one single solitary individual called that thing "good" or that thing "evil" which all the rest of the world regarded in the opposite sense. Not only so; but it might even happen that the genius and persuasiveness of such a person might change into its direct opposite the moral valuation of the whole of humanity. In many quite ordinary cases there may arise a clash between the conventional morality of the community and the verdict of an individual conscience. In such cases it would be towards what the community termed "immoral" that the conscience of the individual would point, and from the thing that the community termed "moral" that it would turn instinctively away.
A conscience of this kind would suffer the pain of remorse when in its weakness it let itself be swayed by the "community-morality" and it would experience the pleasure of relief when in absolute loneliness it defied the verdict of society.
Let us consider now an attribute of man's complex vision which must instantaneously be accepted as basic and fundamental by every living person. I refer to what we call "sensation." The impressions of the outward senses may be criticized. They may be corrected, modified, reduced to order, and supplemented by other considerations. Conclusions based upon them may be questioned. But whatever be done with them, or made by them, they must always remain an integral and inveterate aspect of man's personality.
The sensations of pain and pleasure—who can deny the primordial and inescapable character of these? Not that the pursuit of pleasure or the avoidance of pain can be the unbroken motive-force even of the most hedonistic among us. Our complex vision frequently flings us passionately upon pain. We often embrace pain in an ecstasy of welcome. Nor is this fierce embracing of pain "motivated" by a deliberate desire to get pleasure out of pain. It seems in some strange way due to an attraction towards pain for its own sake—towards pain, as though pain were really beautiful and desirable in itself. One element in all this is undoubtedly due to the desire of the will to assert its freedom and the integrity of its being; in other words to the desire of the will towards the irrational, the capricious, the destructive, the chaotic.
It has been only the least imaginative of philosophers who have taken for granted that man invariably desires his own welfare. Man does not even invariably desire his own pleasure. He desires the reactive vibration of power; and very often this "power" is the power to rush blindly upon destruction. But, whether dominant or not as a motive affecting the will, it remains that our experience of pleasure and pain is a basic experience of the complex vision. And this experience of sensation is not only a passive experience. The attribute of sensation has its active, its energetic, its creative side. No one who has suffered extreme pain or enjoyed exquisite and thrilling pleasures, can deny the curious fact that these things take to themselves a kind of independent life within us and become something very like "entities" or living separate objects.
This phenomenon is due to the fact that our whole personality incarnates itself in the pain or in the pleasure of the moment. Such pain, such pleasure, is the quintessential attenuated "matter" with which our soul clothes itself. At such moments we are the pain; we are the pleasure. Our human identity seems merged, lost, annihilated. Our soul seems no longer our soul. It becomes the soul of the overpowering sensation. We ourselves at such moments become fiery molecules of pain, burning atoms of pleasure. Just as the logical reason can abstract itself from the other primal energies and perform strange and fantastic tricks, so the activity of sensation can so absorb, obsess and overpower the whole personality that the rhythm of existence is entirely broken.
Pain at the point of ecstasy, pleasure at the point of ecstasy, are both of them destructive of those rare moments when our complex vision resolves itself into music. Such music is indeed itself a kind of ecstasy; but it is an ecstasy intellectualized and consciously creative. Pain is present there and pleasure is present there; but they are there only as orchestral notes in a larger unity that has absorbed them and transmuted them.
When a work of art by reason of its sensational appeal reduces us to an ecstasy of pleasure or pain it renders impossible that supreme act of the complex vision by means of which the immortal calm of the ideal vision descends upon the unfathomable universe.
