The act or habit of arrogating, or making undue claims in an overbearing manner; that species of pride which consists in exorbitant claims of rank, dignity, estimation, or power, or which exalts the worth or importance of the person to an undue degree; proud contempt of others; lordliness; haughtiness; self-assumption; presumption.
When power leads man toward arrogance, poetry reminds him of his limitations. When power narrows the area of man's concern, poetry reminds him of the richness and diversity of existence. When power corrupts, poetry cleanses. John F. Kennedy
