“I'll just have them change the entry in the demonology textbook from 'almost extinct' to 'not extinct enough for Alec. He prefers his monsters really, really extinct.”

Will that make you happy?"

“In an individual, selfishness uglifies the soul; for the human species, selfishness is extinction.”

The Pacific Journal of Adam Ewing, Monday, 13th January —, p. 528
Cloud Atlas (2004)
Context: Scholars discern motions in history & formulate these motions into rules that govern the rises & falls of civilizations. My belief runs contrary, however. To wit: history admits no rules; only outcomes.
What precipitates outcomes? Vicious acts & virtuous acts.
What precipitates acts? Belief.
Belief is both prize & battlefield, within the mind & in the mind’s mirror, the world. If we believe humanity is a ladder of tribes, a colosseum of confrontation, exploitation & bestiality, such a humanity is surely brought into being, & history’s Horroxes, Boer-haaves & Gooses shall prevail. You & I, the moneyed, the privileged, the fortunate, shall not fare so badly in this world, provided our luck holds. What of it if our consciences itch? Why undermine the dominance of our race, our gunships, our heritage & our legacy? Why fight the “natural” (oh, weaselly word!) order of things?
Why? Because of this: — one fine day, a purely predatory world shall consume itself. Yes, the Devil shall take the hindmost until the foremost is the hindmost. In an individual, selfishness uglifies the soul; for the human species, selfishness is extinction.
Is this the doom written within our nature?
If we believe that humanity may transcend tooth & claw, if we believe divers races & creeds can share this world as peaceably as the orphans share their candlenut tree, if we believe leaders must be just, violence muzzled, power accountable & the riches of the Earth & its Oceans shared equitably, such a world will come to pass. I am not deceived. It is the hardest of worlds to make real. Torturous advances won over generations can be lost by a single stroke of a myopic president’s pen or a vainglorious general’s sword.

“I would dare say that today this species is facing a very real and true danger of extinction, and no one can be sure, listen to this well, no one can be sure that it will survive this danger.”

Fidel Castro (1926–2016) former First Secretary of the Communist Party and President of Cuba

University of Havana address (2005)
Context: I would dare say that today this species is facing a very real and true danger of extinction, and no one can be sure, listen to this well, no one can be sure that it will survive this danger.
Well, the fact that the species would not survive was discussed about 2,000 years ago. I remember that when I was a student I heard of the Apocalypse, a book of prophesy in the Bible. Apparently, 2000 years ago someone realized that this weak species could one day disappear.

“The dinosaur is for most people the epitome of extinctness, the proto­type of an animal so maladapted to a changing environment that it dies out, leaving fossils but no descendants.”
