Prudence has been an essential leadership virtue historically, but the word has largely fallen out of use. Prudence was considered one of the greatest of virtues two thousand years ago. A hundred years ago it was part of moral philosophy, and today it is the punchline of a joke. For people of a certain generation it will forever conjure up the memory of Dana Carvey impersonating George H. W. Bush saying, “Wouldn’t be wise; wouldn’t be prudent.”
