’Tis good to Provide against All Chances both Sleeping and Waking; for
a Man cannot be too Circumspect, upon Condition on the other hand, that
his Caution do not make him Over-sollicitous. Past Dangers make us Wiser

the Wit to lie in the Hall; which tells us that a Wise Body is not to be
Caught Twice by the same Snare and Trick. His Promise to the _Wolf_ was
a kind of a _Dog-Case of Conscience_, and the _Wolf_ play’d the Fool in
Taking his Word, for That which he was not obliged to Perform.
