„At length the morn and cold indifference came.“

„But tir'd at length poor Beauty slept,
And while she rested, wearied quite,
Indifference to the dear lamp crept,
And quench'd its warm, and splendid light.“

—  Eliza Acton Poet, cook 1799 - 1859

Song (1826)

„The days hardened with cold and boredom like last year's loaves of bread. One began to cut them with blunt knives without appetite, with a lazy indifference.“

„As Adolf Berle, a fellow cold warrior, once remarked, 'Being vindicated by history is cold comfort.' For one thing, the political scars of those with whom one has polemicized seem more long-lasting and painful than their memories of the political issues that gave rise to them. And yet indifference to the political life of one's times I deem a flagrant expression of moral irresponsibility. Those who profess such indifference owe the intellectual and cultural freedoms in which they luxuriate to the commitment and sacrifices of others.“

„Too unconcerned to love and too passionless to hate, too detached to be selfish and too lifeless to be unselfish, too indifferent to experience joy and too cold to express sorrow, they are neither dead nor alive; they merely exist.“

„We went to morning services in variouis places and were deeply impressed by the spiritual poverty of these churches, by the lack of any congregation and the miserable spiritual status of the clergy, the poverty of their sermons, and the nonchalance and indifference of the ritual.“

—  Ingmar Bergman Swedish filmmaker 1918 - 2007

On Winter Light, Jonas Sima interview <!-- pages 173-174 -->
Kontext: We drove about, looking for churches, my father and I. My father, as you probably know, was a clergyman — he knew all the Uppland churches like the back of his hand. We went to morning services in variouis places and were deeply impressed by the spiritual poverty of these churches, by the lack of any congregation and the miserable spiritual status of the clergy, the poverty of their sermons, and the nonchalance and indifference of the ritual.
In one church, I remember — and I think it has a great deal to do with the end of the film — Father and I were sitting together. My father had already been retired for many years, and was old and frail.... Just before the bell begins to toll, we hear a car outside, a shining Volvo: the clergyman climbs out hurriedly, and there is a faint buzz from the vestry, and then the clergyman appears before he ought to — when the bell stops, that is — and says he feels very poorly and that he's talked to the rector and the rector has said he can use an abbrviated form of the service and drop the part at the altar. So there would be just one psalm and a sermon and another psalm. And goes out. Whereon my father, furious, began hammering on the pew, got to his feet and marched out into the vestry, where a long mumbled conversation ensued; after which the churchwarden also went in, then someone ran up the organ gallery to fetch the organist, after which the churchwarden came out and announced that there would be a complete service after all. My father took the service at the altar, but at the beginning and the end.
In some way I feel the end of the play was influenced by my father's intervention — that at all costs one must do what it is one's duty to do, particularly in spiritual contexts. Even if it can seem meaningless.

„What I have achieved has been largely a matter of chance. Many problems I thought about at length with no success. With other problems, there was the inspiration—indeed, some that astound me today. Certainly the best times were when I was alone with mathematics, free of ambition and of pretense, and indifferent to the world.“

„The opposite of love is not hate, it's indifference. The opposite of art is not ugliness, it's indifference. The opposite of faith is not heresy, it's indifference. And the opposite of life is not death, it's indifference. Because of indifference, one dies before one actually dies. To be in the window and watch people being sent to concentration camps or being attacked in the street and do nothing, that's being dead.“

The Spirit of Revolt (1880)
Kontext: Whoever has a slight knowledge of history and a fairly clear head knows perfectly well from the beginning that theoretical propaganda for revolution will necessarily express itself in action long before the theoreticians have decided that the moment to act has come. Nevertheless, the cautious theoreticians are angry at these madmen, they excommunicate them, they anathematize them. But the madmen win sympathy, the mass of the people secretly applaud their courage, and they find imitators. In proportion as the pioneers go to fill the jails and the penal colonies, others continue their work; acts of illegal protest, of revolt, of vengeance, multiply.
Indifference from this point on is impossible. Those who at the beginning never so much as asked what the "madmen" wanted, are compelled to think about them, to discuss their ideas, to take sides for or against. By actions which compel general attention, the new idea seeps into people's minds and wins converts. One such act may, in a few days, make more propaganda than thousands of pamphlets.
Above all, it awakens the spirit of revolt: it breeds daring. The old order, supported by the police, the magistrates, the gendarmes and the soldiers, appeared unshakable, like the old fortress of the Bastille, which also appeared impregnable to the eyes of the unarmed people gathered beneath its high walls equipped with loaded cannon. But soon it became apparent that the established order has not the force one had supposed.

„Relativism is not indifference; on the contrary, passionate indifference is necessary in order for you not to hear the voices that oppose your absolute decrees“

—  Karel Čapek Czech writer 1890 - 1938

"On Relativism" (1925)
Kontext: Socialism is good when it comes to wages, but it tells me nothing when it comes to other questions in life that are more private and painful, for which I must seek answers elsewhere. Relativism is not indifference; on the contrary, passionate indifference is necessary in order for you not to hear the voices that oppose your absolute decrees … Relativism is neither a method of fighting, nor a method of creating, for both of these are uncompromising and at times even ruthless; rather, it is a method of cognition. If one must fight or create, it is necessary that this be preceded by the broadest possible knowledge... One of the worst muddles of this age is its confusing of the ideas behind combative and cognitive activity. Cognition is not fighting, but once someone knows a lot, he will have much to fight for, so much that he will be called a relativist because of it.

„Whatever dwelt among the stars had nothing to do with earthly concerns. I wonder if you will understand me if I said, staring at the indifference of the cold heavens, that I never felt less religious than in that moment, but staring at their majesty, the grandeur, I never felt more. Cruel Saturn’s created world was worthy of awe.“
