The great advantages of simulation and dissimulation are three. First to lay asleep opposition and to surprise. For where a man's intentions are published, it is an alarum to call up all that are against them. The second is to reserve a man's self a fair retreat: for if a man engage himself, by a manifest declaration, he must go through, or take a fall. The third is, the better to discover the mind of another. For to him that opens himself, men will hardly show themselves adverse; but will fair let him go on, and turn their freedom of speech to freedom of thought.
