Quotes about willingness

“Patriotism is the willingness to kill and be killed for trivial reasons”

“Prayer is not overcoming God's reluctance. It is laying hold of His willingness.”

Hour of Gold, Hour of Lead: Diaries and Letters of Anne Morrow Lindbergh, 1929-1932 (1973), p. 3
Source: Gift from the Sea
Context: I do not believe that sheer suffering teaches. If suffering alone taught, all the world would be wise, since everyone suffers. To suffering must be added mourning, understanding, patience, love, openness and the willingness to remain vulnerable. All these and other factors combined, if the circumstances are right, can teach and can lead to rebirth.

Interview with David Frost (1974)

The Golden Speech (1601)

“I consider that willingness to criticize Russia and Stalin is the test of intellectual honesty.”
Letter to John Middleton Murry (5 August 1944), published in The Collected Essays, Journalism, & Letters, George Orwell: As I Please, 1943-1945 (2000), edited by Sonia Orwell and Ian Angus
Context: Of course, fanatical Communists and Russophiles generally can be respected, even if they are mistaken. But for people like ourselves, who suspect that something has gone very wrong with the Soviet Union, I consider that willingness to criticize Russia and Stalin is the test of intellectual honesty. It is the only thing that from a literary intellectual's point of view is really dangerous.

Source: The Devil and Miss Prym [O Demônio e a srta Prym] (2000), p. x; this has also been misquoted as "A moment is more than enough time for us to decide whether or not to accept our destiny."
Context: When we least expect it, life sets us a challenge to test our courage and willingness to change; at such a moment, there is no point in pretending that nothing has happened or in saying that we are not ready. The challenge will not wait. Life does not look back. A week is more than enough time for us to decide whether or not to accept our destiny.

“Earnestness means willingness to live with energy, though energy bring pain.”
Lectures XI, XII, AND XIII : "Saintliness" https://en.wikisource.org/wiki/The_Varieties_of_Religious_Experience/Lectures_XI,_XII,_and_XIII
1900s, The Varieties of Religious Experience (1902)
Context: One mode of emotional excitability is exceedingly important in the composition of the energetic character, from its peculiarly destructive power over inhibitions. I mean what in its lower form is mere irascibility, susceptibility to wrath, the fighting temper; and what in subtler ways manifests itself as impatience, grimness, earnestness, severity of character. Earnestness means willingness to live with energy, though energy bring pain. The pain may be pain to other people or pain to one's self — it makes little difference; for when the strenuous mood is on one, the aim is to break something, no matter whose or what. Nothing annihilates an inhibition as irresistibly as anger does it; for, as Moltke says of war, destruction pure and simple is its essence.

2016, State of the Union address (January 2016)
Context: But democracy does require basic bonds of trust between its citizens. It doesn't – it doesn't work if we think the people who disagree with us are all motivated by malice, it doesn't work if we think that our political opponents are unpatriotic or trying to weaken America. Democracy grinds to a halt without a willingness to compromise or when even basic facts are contested or when we listen only to those who agree with us. Our public life withers when only the most extreme voices get all the attention. And most of all, democracy breaks down when the average person feels their voice doesn't matter; that the system is rigged in favor of the rich or the powerful or some special interest. [... ] So, my fellow Americans, whatever you may believe, whether you prefer one party or no party, whether you supported my agenda or fought as hard as you could against it, our collective futures depends on your willingness to uphold your duties as a citizen, to vote, to speak out, to stand up for others, especially the weak, especially the vulnerable, knowing that each of us is only here because somebody somewhere stood up for us. We need every American to stay active in our public life and not just during election time so that our public life reflects the goodness and the decency that I see in the American people every single day.

1860s, Fourth of July Address to Congress (1861)
Context: It might seem at first thought to be of little difference whether the present movement at the South be called "secession" or "rebellion." The movers, however, well understand the difference. At the beginning they knew they could never raise their treason to any respectable magnitude by any name which implies violation of law. They knew their people possessed as much of moral sense, as much of devotion to law and order, and as much pride in and reverence for the history and Government of their common country as any other civilized and patriotic people. They knew they could make no advancement directly in the teeth of these strong and noble sentiments. Accordingly, they commenced by an insidious debauching of the public mind. They invented an ingenious sophism, which, if conceded, was followed by perfectly logical steps through all the incidents to the complete destruction of the Union. The sophism itself is that any State of the Union may consistently with the National Constitution, and therefore lawfully and peacefully, withdraw from the Union without the consent of the Union or of any other State. The little disguise that the supposed right is to be exercised only for just cause, themselves to be the sole judge of its justice, is too thin to merit any notice. With rebellion thus sugar coated they have been drugging the public mind of their section for more than thirty years, and until at length they have brought many good men to a willingness to take up arms against the Government the day after some assemblage of men have enacted the farcical pretense of taking their State out of the Union who could have been brought to no such thing the day before.

1980s, First term of office (1981–1985), First Inaugural address (1981)
Context: Directly in front of me, the monument to a monumental man, George Washington, father of our country. A man of humility who came to greatness reluctantly. He led Americans out of revolutionary victory into infant nationhood. Off to one side, the stately memorial to Thomas Jefferson. The Declaration of Independence flames with his eloquence. And then, beyond the Reflecting Pool, the dignified columns of the Lincoln Memorial. Whoever would understand in his heart the meaning of America will find it in the life of Abraham Lincoln.
Beyond those monuments to heroism is the Potomac River, and on the far shore the sloping hills of Arlington National Cemetery, with its row upon row of simple white markers bearing crosses or Stars of David. They add up to only a tiny fraction of the price that has been paid for our freedom. Each one of those markers is a monument to the kind of hero I spoke of earlier. Their lives ended in places called Belleau Wood, the Argonne, Omaha Beach, Salerno, and halfway around the world on Guadalcanal, Tarawa, Pork Chop Hill, the Chosin Reservoir, and in a hundred rice paddies and jungles of a place called Vietnam.
Under one such marker lies a young man, Martin Treptow, who left his job in a small town barber shop in 1917 to go to France with the famed Rainbow Division. There, on the western front, he was killed trying to carry a message between battalions under heavy artillery fire.
We are told that on his body was found a diary. On the flyleaf under the heading, "My Pledge," he had written these words: "America must win this war. Therefore, I will work, I will save, I will sacrifice, I will endure, I will fight cheerfully and do my utmost, as if the issue of the whole struggle depended on me alone."
The crisis we are facing today does not require of us the kind of sacrifice that Martin Treptow and so many thousands of others were called upon to make. It does require, however, our best effort and our willingness to believe in ourselves and to believe in our capacity to perform great deeds, to believe that together with God's help we can and will resolve the problems which now confront us. And after all, why shouldn't we believe that? We are Americans.
