"Tyranny is the opposite of authority."

...Some people have an instinctive itch of irritation against the word "authority." Either they suppose that authority is a pompous name for mere bullying, or else, at the best, they think that mere bullying is an excess of authority. But bullying is almost the opposite of authority. Tyranny is the opposite of authority. For authority simply means right; and nothing is authoritative except what somebody has a right to do, and therefore is right in doing. It often happens in this imperfect world that he has the right to do it and not the power to do it. But he cannot have a shred of authority if he merely has the power to do it and not the right to do it. If you think any form of mastery unjust, it is enough to say that you do not like injustice; but there is no need to say you do not like authority. For injustice, as such, cannot have any authority at all. Moreover, a man can only have authority by admitting something better than himself; and the bully does not get his claim from anybody but himself. It is not the question, therefore, of there being authority, and then tyranny, which is too much authority; for tyranny is not authority. Tyranny means too little authority; for though, of course, an individual may use wrongly the power that may go with it, he is in that act disloyal to the law of right, which should be his own authority. To abuse authority is to attack authority. A policeman is no longer a policeman when he is bribed privately to arrest an innocent man; he is a private criminal. He is not exaggerating authority; he is reducing it to nothing.
