Words are always getting conventionalized to some secondary meaning. It is one of the works of poetry to take the truants in custody and bring them back to their right senses.
Overcome the Empyrean; hurl
Heaven and Earth out of their places,
That in the same calamity
Brother and brother, friend and friend,
Family and family,
City and city may contend.
Come, heart, where hill is heaped upon hill:
For there the mystical brotherhood
Of sun and moon and hollow and wood
And river and stream work out their will.
It takes more courage to dig deep in the dark corners of your own soul and the back alleys of your society than it does for a soldier to fight on the battlefield.
