"No man should tell a lie unless he is shrewd enough to recognize the time for renouncing it, if and when it comes, and knows how to renounce it gracefully."

One should not as a rule reveal one's secrets, since one does not know if and when one may need them again. The essential English leadership secret does not depend on particular intelligence. Rather, it depends on a remarkably stupid thick-headedness. The English follow the principle that when one lies, one should lie big, and stick to it. They keep up their lies, even at the risk of looking ridiculous.
