There is nothing makes a man suspect much, more than to know little; and therefore men should remedy suspicion, by procuring to know more, and not to keep their suspicions in smother. What would men have? Do they think, those they employ and deal with, are saints? Do they not think, they will have their own ends, and be truer to themselves, than to them? Therefore there is no better way, to moderate suspicions, than to account upon such suspicions as true, and yet to bridle them as false. For so far a man ought to make use of suspicions, as to provide, as if that should be true, that he suspects, yet it may do him no hurt. Suspicions that the mind of itself gathers, are but buzzes; but suspicions that are artificially nourished, and put into men's heads, by the tales and whisperings of others, have stings.
