Prudence

Cardinal Virtue of Prudence from Judaism, Plato, and later adapted by Augustine, Ambrose, Aquinas, and here continued by Clive Staples Lewis:

 "...Christ never meant that we were to remain children in intelligence:  on the contrary, He told us to be not only 'as harmless as doves', but also 'as wise as serpents'.  He wants a child's heart, but a grown-up's head.  He wants us to be simple, single-minded, affectionate, and teachable, as good children are; but He also wants every bit of intelligence we have to be alert at its job, and in first class fighting trim."

1898-1963
