It is as impossible for a man to be cheated by any one but himself, as for a thing to be and not to be at the same time.
Ibid.
Ralph Waldo Emerson
It is better to suffer wrong than to do it, and happier to be sometimes cheated than not to trust. —Samuel Johnson, The Rambler
Samuel Johnson
5004 Every man takes care that his neighbor does not cheat him. But a day comes when he begins to care that he does not cheat his neighbor. Then all goes well.
