The difficulty with pride is that there is no obvious barrier between constructive pride yielding excellence, and destructive vainglory yielding boastfulness. Vainglory, the older sibling to pride, is the most puissant enemy a knight or noble will ever face. Vainglory cannot be killed; it strikes unseen by the victim, but is obvious to those around them who are often powerless to lend any assistance. Vainglory is a plight that blinds, quietly seducing men to cover their own eyes with blinders of woven rationalization. These blinders are indeed works of art in their own right; for the individual strands are truths, woven together with logic such that the finished whole whispers pleasant falsehoods directly to the innermost self. And though it is false, this comfortable fantasy finds ready acceptance because it is what we has human beings want to hear that we are right.
Because we are human, most of us struggle against the specter of vainglory, of self-deception, for our entire lives. But also being human, we are provided with tools used in defense of the soul against such assaults, namely: integrity, faith, humility.
Integrity is personal honor, consistence in applying your personal values to every action.
Faith is the belief in the ideal rightness? that gives you the strength even with a complete absence of evidence.
And finally humility, humiliates. Because humility is not flashy, it gains less respect as a weapon of virtue than do courage, loyalty, largesse or fidelity. But none of these other virtues are of any assistance when it comes to combat with vainglory, with the mirrored ghosts of our own righteousness. Although vainglory cannot be killed, it can be held at bay if the gentle wields humility with sincerity. For used sincerely, humility makes the invisible specter more plain to see, refuses the comfort of praise, keeps you listening to the quiet ring of truth in your own heart, and confers a measure of grace.
