“Now what is aggression? Aggression is another name for government. Aggression, invasion, government are interconvertible terms. The essence of government is control, or the attempt to control. He who attempts to control another is a governor, an aggressor, and invader, and the nature of such invasions is not changed, whether it is made by one man upon another man, after the matter of the ordinary criminal, or by one man upon all other men, after the manner of an absolute monarch, or by all other men upon one man, after the manner of modern democracy. On the other hand, he who resists another’s attempt to control is not an aggressor, an invader, a governor, but simply a defender, a protector; and the nature of such resistance is not changed whether it be offered by one man to another man, as when repels a criminal’s onslaught, or by one man to all other men, as when one declines to obey an oppressive law . . . This distinction between invasion and resistance, between government and defence, is vital. Without it there can be no valid philosophy of politics.”
