Cowardice is badly misunderstood. People act to their capabilities. Those who do the things we call heroic often just follow instinct, they almost never plan an action based on valor.
It can be cowardly to go to war and brave to resist it. Likewise, it can be brave to resist your heart when it pushes you towards desire. Nothing is more capricious and untrustworthy than our yearning heart. To view love with skepticism is to apply proper wisdom.
The greatest cowardice is that based on ease and comfort. To refuse to stand up against an injustice or in support of a loved one simply because it would require effort is the most shameful act.
We should respect everyone who doubts, but freely condemn anyone who can’t find the time to do what they know is right.
