The demagogue is usually sly, a detractor of others, a professor of humility and disinterestedness, a great stickler for equality as respects all above him, a man who acts in corners, and avoids open and manly expositions of his course, calls blackguards gentlemen, and gentlemen folks, appeals to passions and prejudices rather than to reason, and is in all respects, a man of intrigue and deception, of sly cunning and management.
