The counsels of a wise man are certain, but events are uncertain: and yet if I have passed a rash promise, I will in some degree punish the temerity of making it with the damage of keeping it, unless it turn very much to my shame or detriment, and then I will be my own confessor in the point, and rather be once guilty of denying, than always of giving. It is not with a benefit as with a debt—it is one thing to trust an ill paymaster, and another thing to oblige an unworthy person—the one is an ill man, and the other only an ill husband.
