The power of measuring the danger, together with a certain alertness and watchfulness, is very important. There should be a balance of these two, Prudence and Courage;Prudence in contemplation, Courage in execution.Lord Bacon says: “In meditation all dangers should be seen; in execution one, unless very formidable.”Connected with these qualities,properly an outgrowth of them, is a third, viz:promptness. The mind convinced, the act should follow. In the words of Macbeth; “Henceforth the very firstlings of my heart shall be the firstlings of my hand.” Think, act, promptly.
