Favonius Cornelius is very pertinent here-the Legions were the epitome of professional excellence ,consider what they actually achieved ,and their utter deadliness. The Stoic ideal is often overlooked but may I suggest strong parallels with Samurai Zen ? Extreme physical effort and life threatening situations often give a sublime mental clarity beyond the actual event. The Stoic ideal gives a very calm and centred view of the world and the fleeting nature of the flesh, and is a comfort to the rational man beset by enemies, neither does it belittle human endeavour . Quintus in Gladiator and General Kurugame in Ran are worth looking at as modern sketches of such philosophies.Philosophy is fine as an abstract goal but remember the prodigies of valour the Legions actually achieved.
