“I have heard so much about the perils ahead that I have had nightmares for several nights, in which I lived through all the horrors of war... The militia are quartered in the studio, hence there is no way of using it. I do not read the newspapers much any more; one a day is enough for me. The Prussian atrocities upset me, and I want to retain my composure... Would you believe that I am accustomed to the sound of the canon [of the Prussians]? It seems to me that I am now absolutely inured to war and capable of enduring everything.”

Original: Je suis un grand artiste et je le sais. C'est parce que je le suis que j'ai tellement enduré de souffrances. Pour poursuivre ma voie, sinon je me considérerai comme un brigand. Ce que je suis du reste pour beaucoup de personnes. Enfin, qu'importe! Ce qui me chagrine le plus c'est moins la misère que les empêchements perpétuels à mon art que je ne puis faire comme je le sens et comme je pourais le faire sans la misère qui me lie les bras. Tu me dis que j'ai tort de rester éloigné du centre artistique. Non, j'ai raison, je sais depuis longtemps ce que je fais et pourquoi je le fais. Mon centre artistique est dans mon cerveau et pas ailleurs et je suis fort parce que je ne suis jamais dérouté par les autres et je fais ce qui est en moi.

Context: It matters not where you live, or what rank of life you hold, the evil or the blessing will reach you all. The far and the near, the home counties and the back, the rich and the poor, will suffer or rejoice alike. The heart that feels not now is dead; the blood of his children will curse his cowardice, who shrinks back at a time when a little might have saved the whole, and made them happy. I love the man that can smile in trouble, that can gather strength from distress, and grow brave by reflection. 'Tis the business of little minds to shrink; but he whose heart is firm, and whose conscience approves his conduct, will pursue his principles unto death.
My own line of reasoning is to myself as straight and clear as a ray of light. Not all the treasures of the world, so far as I believe, could have induced me to support an offensive war, for I think it murder; but if a thief breaks into my house, burns and destroys my property, and kills or threatens to kill me, or those that are in it, and to "bind me in all cases whatsoever" to his absolute will, am I to suffer it? What signifies it to me, whether he who does it is a king or a common man; my countryman or not my countryman; whether it be done by an individual villain, or an army of them? If we reason to the root of things we shall find no difference; neither can any just cause be assigned why we should punish in the one case and pardon in the other. Let them call me rebel and welcome, I feel no concern from it; but I should suffer the misery of devils, were I to make a whore of my soul by swearing allegiance to one whose character is that of a sottish, stupid, stubborn, worthless, brutish man.
