„Imagine no possessions,
I wonder if you can;
No need for greed or hunger –
A brotherhood of man;
Imagine all the people
Sharing all the world…“
— John Lennon English singer and songwriter 1940 - 1980
You may say I'm a dreamer,
But I'm not the only one;
I hope some day you will join us,
And the world will live as one.

„That's why the peoples have to die -- so that the Jew can live. He drives the peoples to war to make a profit from the fratricide of the white race.
In the World War 11 million gentiles had to die. The Jew was the winner.“
— Julius Streicher German politician 1885 - 1946
Deswegen müssen die Völker sterben, damit der Jude leben kann. Er hetzt die Völker zum Krieg, um aus dem Brudermord der weißen Rasse Gewinn zu ziehen.
Im Weltkrieg mussten 11 Millionen Nichtjuden sterben. Der Jude aber war der Sieger.
05/20/1932, speech in the Hercules Hall in Nuremberg ("Kampf dem Weltfeind", Stürmer publishing house, Nuremberg, 1938)

„But in the imagination anything goes that can be imagined, and the limit of the imagination is a totally human world.“
— Northrop Frye Canadian literary critic and literary theorist 1912 - 1991
"Quotes", The Educated Imagination (1963), Talk 1: The Motive For Metaphor http://northropfrye-theeducatedimagination.blogspot.ca/2009/08/1-motive-for-metaphor.html
Context: At the level of ordinary consciousness the individual man is the centre of everything, surrounded on all sides by what he isn't. At the level of practical sense, or civilization, there's a human circumference, a little cultivated world with a human shape, fenced off from the jungle and inside the sea and the sky. But in the imagination anything goes that can be imagined, and the limit of the imagination is a totally human world.
„I say the entities that are named as gods by Earthians are imagined into being by Earthians as personal helper-buddies, justifiers, threateners (my god can beat up your god). They don't "run on" anything any more than a mirror image "runs on" anything. They merely reflect what people want them to be.“
— Sheri S. Tepper American fiction writer 1929 - 2016
Strange Horizons interview (2008)
Context: I say the entities that are named as gods by Earthians are imagined into being by Earthians as personal helper-buddies, justifiers, threateners (my god can beat up your god). They don't "run on" anything any more than a mirror image "runs on" anything. They merely reflect what people want them to be. "I want to have more children than my brother does, thus proving I'm a better man than he is, so my god tells me I should have a big family." "I want to screw women, so my god is going to give me seventy virgins I can screw for all eternity." The "gods" in The Margarets who could really do anything were actually an old, highly evolved race of real people. The others were only reflections. The real God, who may really exist, is outside all that, perhaps watching closely, perhaps merely asleep for a few trillion years while the experiment runs out.
We — thee and me as individuals — will never know that God, though after a few trillion years, the universe as a whole may come to understand that God.
„War may be unavoidable sometimes, but its progeny are terrible to contemplate. Not mere killing, for man must die, but the deliberate and persistent propagation of hatred and falsehood, which gradually become the normal habits of the people.“
The Discovery of India (1946)
Context: The world of today has achieved much, but for all its declared love for humanity, it has based itself far more on hatred and violence than on the virtues that make one human. War is the negation of truth and humanity. War may be unavoidable sometimes, but its progeny are terrible to contemplate. Not mere killing, for man must die, but the deliberate and persistent propagation of hatred and falsehood, which gradually become the normal habits of the people. It is dangerous and harmful to be guided in our life's course by hatreds and aversions, for they are wasteful of energy and limit and twist the mind and prevent it from perceiving truth.
„Letting men die is a money-saving device. Safety costs money… as one safety official put it, ‘When everything is hurry, hurry, hurry, when you start pressuring people and taking shortcuts, things can go wrong. And then people die.’ No. And then men die.“

„Life is a gamble. You can get hurt, but people die in plane crashes, lose their arms and legs in car accidents; people die every day. Same with fighters: some die, some get hurt, some go on. You just don't let yourself believe it will happen to you.“

„In a population of hundreds of millions, such a small number of people is a mere drop in the bucket… but enough drops can make any bucket overflow“
