It means that we must deal smartly and cunningly with cunning people. We should use their tricks on themselves. For example, in the fable of the fox and the crane, bye serving soup in a plate the fox "played the fox with the fox" (Here the crane was at fault as he acted cunningly at first, and the fox took revenge by "playin the fox").
It means that with wicked people we must not behave friendly and we should be alert and instead try their own wickedness on them
Thomas Fullerβs phrase "With foxes, we must play the fox" suggests that when dealing with cunning people, we should also be clever and strategic. This reflects a broader understanding of human behavior and strategy in social interactions, emphasizing the need to adapt based on the character of others. It encourages using wit and cunning in response to similar traits in others to protect oneself and achieve oneβs goals.
