The first man who, having enclosed a piece of land, thought of saying, "This is mine", and found people simple enough to believe him, was the real founder of civil society. How many crimes, wars and murders, how much misery and horror the human race would have been spared if someone had pulled up the stakes and filled in the ditch and cried out to his fellow men: "Beware of listening to this impostor. You are lost if you forget that the fruits of the earth belong to everyone, and that the earth itself belongs to no one!" But it is highly probable that by this time things had reached a point beyond which they could not go on as they were; for the idea of property, depending on many prior ideas which could only have arisen in successive stages, was not formed all at once in the human mind.
