As courage and intelligence are the two qualities best worth a good man’s cultivation, so it is the first part of intelligence to recognise our precarious estate in life, and the first part of courage to be not at all abashed before the fact. A frank and somewhat headlong carriage, not looking too anxiously before, not dallying in maudlin regret over the past, stamps the man who is well armoured for this world.
And not only well armoured for himself, but a good friend and a good citizen to boot. We do not go to cowards for tender dealing; there is nothing so cruel as panic; the man who has least fear for his own carcass, has most time to consider others.
