There be three degrees of hiding and veiling of a man’s self. The first, closeness, reservation, and secrecy; when a man leaveth himself without observation, or without hold to be taken, what he is. The second, dissimulation, in the negative; when a man lets fall signs and arguments, that he is not, that he is. And the third, simulation, in the affirmative; when a man industriously and expressly feigns and pretends to be, that he is not.
– Francis Bacon, “Of Simulation and Dissimulation,” Essays (1597)
