He is the hoarder of the general benefit. He is the monster avid for the greedy rights of ‘my and mine.’ The havoc wrought by him is described in mythology and fairy tale as being universal throughout his domain. This may be no more than his household, his own tortured psyche, or the lives that he blights with the touch of his friendship and assistance; or it may amount to the extent of his civilization. The inflated ego of the tyrant is a curse to himself and his world – no matter how his affairs may seem to prosper. Self-terrorized, fear-haunted, alert at every hand to meet and battle back the anticipated aggressions of his environment, which are primarily the reflections of the uncontrollable impulses to acquisition within himself, the giant of self-achieved independence is the world’s messenger of disaster, even though, in his mind, he may entertain himself with humane intentions. Wherever he sets his hand there is a cry (if not from the housetops, then – more miserably – within every heart): a cry for the redeeming hero, the carrier of the shining blade, whose blow, whose touch, whose existence, will liberate the land.
