Walls

Indeed, we do not really live unless we have friends surrounding us like a firm wall against the winds of the world.
- Charles Hanson Towne

With the pride of an artist, you must blow against the walls of every power that exists, the small trumpet of your defiance.
- Norman Mailer

Wisdom never kicks at the iron walls it can't bring down.
- Olive Schreiner

Each time a man stands up for an ideal, or acts to improve the lot of others, or strikes out against injustice, he sends forth a tiny ripple of hope ... and crossing each other from a million different centers of energy and daring those ripples build a current that can sweep down the mightiest walls of oppression and resistance.
- Robert F. Kennedy, 1925 - 1968

Once more unto the breach, dear friends, once more,
Or close the wall up with our English dead!
In peace there's nothing so becomes a man
As modest stillness and humility;
But when the blast of war blows in our ears,
Then imitate the action of the tiger.
- William Shakespeare, Henry V

Most of us can read the writing on the wall; we just assume it's addressed to someone else.
- Ivern Ball
