Egotism utilises the sufferings of others for its own ends. No doubt cruelty is often a consequence of sheer callousness. The man who has no perception of the pain he is causing or no sympathy with the sufferers will trample them under foot on the least provocation. He feels supremely indifferent to their agonies when they are writhing beneath him, and therefore he will never consider it incumbent on him to adjust his conduct with the least reference to the pain he gives. That is an entirely irrelevant consideration. The least inconvenience to himself outweighs the greatest distress of other people, for the simple reason that that distress counts as nothing in his calculation of motives. In Haman's case, however, we do not meet with this attitude of simple indifference. The grand vizier is irritated, and he vents his annoyance in a vast explosion of malignity that must take account of the agony it produces, for in that agony its own thirst for vengeance is to be slaked. But this only shows the predominant selfishness to be all the greater. It is so great that it reverses the engines that drive society along the line of mutual helpfulness, and thwarts and frustrates any amount of human life and happiness for the sole purpose of gratifying its own desires.
Then the selfishness of vanity promotes cruelty still further by another of its effects. It destroys the sense of proportion. Self is not only regarded as the centre of the universe; like the sun surrounded by the planets, it is taken to be the greatest object, and everything else is insignificant when compared to it. What is the slaughter of a few thousand Jews to so great a man as Haman, grand vizier of Persia? It is no more than the destruction of as many flies in a forest fire that the settler has kindled to clear his ground. The same self-magnification is visibly presented by the Egyptian bas-reliefs, on which the victorious Pharaohs appear as tremendous giants driving back hordes of enemies or dragging pigmy kings by their heads. It is but a step from this condition to insanity, which is the apotheosis of vanity. The chief characteristic of insanity is a diseased enlargement of self. If he is elated the madman regards himself as a person of supreme importance--as a prince, as a king, even as God. If he is depressed he thinks that he is the victim of exceptional malignity. In that case he is beset by watchers of evil intent; the world is conspiring against him; everything that happens is part of a plot to do him harm. Hence his suspiciousness; hence his homicidal proclivities. He is not so mad in his inferences and conclusions. These may be rational and just, on the ground of his premisses. It is in the fixed ideas of these premisses that the root of his insanity may be detected. His awful fate is a warning to all who venture to indulge in the vice of excessive egotism.
