“Can you see other people's battles as your own? There are so many similarities in every war in this world. Some are fighting for freedom and independence. Some fight for principles and ideals. But there are also those who fight only for their blind faith and ego.”

1930s, Speech to the Democratic National Convention (1936)
Context: We do not see faith, hope, and charity as unattainable ideals, but we use them as stout supports of a nation fighting the fight for freedom in a modern civilization.
Faith — in the soundness of democracy in the midst of dictatorships.
Hope — renewed because we know so well the progress we have made.
Charity — in the true spirit of that grand old word. For charity literally translated from the original means love, the love that understands, that does not merely share the wealth of the giver, but in true sympathy and wisdom helps men to help themselves.

Variant: Simply, all what we did is that we avoided the country a big crisis and a battle between Egyptians. Beware, instead of Egyptians fighting each other, no, you can fight us, and we protect all. how many would fight us? but Egyptians fighting each other would be a big war we couldn't have had the ability to deal with.

Talking about Busted Flush the Wild Cards novel, Interview on Pat's Fantasy Hotlist http://fantasyhotlist.blogspot.com/2008/12/interview-with-george-r-r-martin-and.html (December 2008)
Context: With great power comes great responsibility, Stan Lee once wrote. Spidey's credo articulates the basic premise of every superhero universe, including ours. But Lord Acton wrote that power corrupts, and absolute power corrupts absolutely. The tension between those two truths is where the drama comes in. My own heroes are the dreamers, those men and women who tried to make the world a better place than when they found it, whether in small ways or great ones. Some succeeded, some failed, most had mixed results... but it is the effort that's heroic, as I see it. Win or lose, I admire those who fight the good fight.

Light (1919), Ch. XVI - De Profundis Clamavi
Context: War will come again after this one. It will come again as long as it can be determined by people other than those who fight. The same causes will produce the same effects, and the living will have to give up all hope.

"In Praise of the Fighters" (song)
Variant translation: There are men who struggle for a day and they are good.
There are men who struggle for a year and they are better.
There are men who struggle many years, and they are better still.
But there are those who struggle all their lives:
These are the indispensable ones.
As quoted in Democracy Unbound : Progressive Challenges to the Two Party System (1997) by David Reynolds; also quoted by Cuban musician and poet Silvio Rodríguez before his song "Sueño con serpientes".
Also quoted by Eduardo Galeano (Uruguayan writer) to describe Nestor Kirchner as he received the notice of his death.
