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.
