“She shrieks above the din. "If you wish a battle, I shall give it. I am the last of my kind. I shall not lie down without a fight.”

The Wild Swans at Coole (1919)
Context: I know that I shall meet my fate
Somewhere among the clouds above;
Those that I fight I do not hate,
Those that I guard I do not love;
My county is Kiltartan Cross,
My countrymen Kiltartan’s poor,
No likely end could bring them loss
Or leave them happier than before.
Nor law, nor duty bade me fight,
Nor public men, nor cheering crowds,
A lonely impulse of delight
Drove to this tumult in the clouds;
I balanced all, brought all to mind,
The years to come seemed waste of breath,
A waste of breath the years behind
In balance with this life, this death.

"Dilemma of a Pacifist"(1937)
Context: I know now that there are things for which I am prepared to die. I am willing to die for political freedom; for the right to give my loyalty to ideals above a nation and above a class; for the right to teach my child what I think to be the truth; for the right to explore such knowledge as my brains can penetrate; for the right to love where my mind and heart admire, without reference to some dictator’s code to tell me what the national canons on the matter are; for the right to work with others of like mind; for a society that seems to me becoming to the dignity of the human race.
I shall pick no fight, nor seek to impose by force these standards on others. But let it be clear. If the fight comes unsolicited, I am not willing to die meekly, to surrender without effort. And that being so, am I still a pacifist?

The Tragic Sense of Life (1913), VI : In the Depths of the Abyss
Context: I will not say that the more or less poetical and unphilosophical doctrines that I am about to set forth are those which make me live; but I will venture to say that it is my longing to live and to live for ever that inspires these doctrines within me. And if by means of them I succeed in strengthening and sustaining this same longing in another, perhaps when it is all but dead, then I shall have performed a man's work, and above all, I shall have lived. In a word, be it with reason or without reason or against reason, I am resolved not to die. And if, when at last I die out, I die altogether, then I shall not have died out of myself — that is, I shall not have yielded myself to death, but my human destiny shall have killed me. Unless I come to lose my head, or rather my heart, I will not abdicate from life — life will be wrested from me.

Final proclamation to the people of Colombia (8 December 1830), as quoted in Man of Glory : Simón Bolívar (1939) by Thomas Rourke
Variant translations: If my death contributes to the end of the parties and the consolidation of the Union, I shall go quietly to my grave.
Colombians! my last wishes are for the welfare of the fatherland. If my death contributes to the cessation of party strife, and to the consolidation of the Union, I shall descend in peace to the grave.
For my enemies I have only forgiveness. If my death shall contribute to the cessation of factions and the consolidation of the Union, I can go tranquilly to my grave.
