Temperance is love surrendering itself wholly to Him who is its object; courage is love bearing all things gladly for the sake of Him who is its object; justice is love serving only Him who is its object, and therefore rightly ruling; prudence is love making wise distinction between what hinders and what helps itself.
There is another form of temptation, even more fraught with danger. This is the disease of curiosity. It is this which drives us to try and discover the secrets of nature, those secrets which are beyond our understanding, which can avail us nothing and which man should not wish to learn.
