Either in life... or in death... in this modern era?
First of all, C.S. Lewis was an Anglican, not a Roman Catholic. Secondly, Cicero said "How sweet and glorious it is to die for one's country." Really? Sweet and glorious to die for Hitler's Germany? Or for the filthy, cruel Romans? Thirdly, during the triumphs held in ancient Rome, the hero of the hour was led by a man dressed in a simple tunic, who reminded the hero that all glory is fleeting. And finally, this aphorism, which is one of the truest ever written or spoken: "The paths of glory lead but to the grave." Why try to achieve glory, which is all about self? Instead, try to make the world a better place for others.
