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 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.
