The moment one abandons the idea that he was born to discover what is right and enforce it upon the rest of the world, he begins to feel an increasing disposition to let others alone and to refrain even from retaliation or resistance except in those emergencies which immediately and imperatively require it.
Anarchism is for liberty, and neither for nor against anything else. Anarchy is the mother of co-operation, yes, just as liberty is the mother of order; but, as a matter of definition, liberty is not order nor is Anarchism co-operation. I define Anarchism as the belief in the greatest amount of liberty compatible with equality of liberty; or, in other words, as the belief in every liberty except the liberty to invade.
The Anarchists answer that the abolition of the State will leave in existence a defensive association, resting no longer on a compulsory but on a voluntary basis, which will restrain invaders by any means that may prove necessary.
Aggression is simply 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, an invader; and the nature of such invasion is not changed, whether it is made by one man upon another man, after the manner 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 a modern democracy.
The makers of dictionaries are dependent upon specialists for their definitions. A specialist's definition may be true or it may be erroneous. But its truth cannot be increased or its error diminished by its acceptance by the lexicographer. Each definition must stand on its own merits.
