Strength, Courage, Mastery, and Honor are the alpha virtues of men all over the world. They are the fundamental virtues of men because without them, no 'higher' virtues can be entertained. You need to be alive to philosophize. You can add to these virtues and you can create rules and moral codes to govern them, but if you remove them from the equation altogether you aren't just leaving behind the virtues that are specific to men, you are abandoning the virtues that make civilization possible.
