An old Mayan story from the movie Apocalypto:
And a Man sat alone, drenched deep in sadness. And all the animals drew near to him and said, “We do not like to see you so sad. Ask us for whatever you wish and you shall have it.” The Man said, “I want to have good sight.” The vulture replied, “You shall have mine.” The Man said, “I want to be strong.” The jaguar said, “You shall be strong like me.” Then the Man said, “I long to know the secrets of the earth.” The serpent replied, “I will show them to you.” And so it went with all the animals. And when the Man had all the gifts that they could give, he left. Then the owl said to the other animals, “Now the Man knows much, he’ll be able to do many things. Suddenly I am afraid.” The deer said, “The Man has all that he needs. Now his sadness will stop.” But the owl replied, “No. I saw a hole in the Man, deep like a hunger he will never fill. It is what makes him sad and what makes him want. He will go on taking and taking, until one day the World will say, ‘I am no more and I have nothing left to give.'”
Which kind of echoes this quote from H.G. Well’s Things to Come:
Oswald Cabal: Rest enough for the individual man – too much, and too soon – and we call it death. But for Man, no rest and no ending. He must go on, conquest beyond conquest. First this little planet with its winds and ways, and then all the laws of mind and matter that restrain him. Then the planets about him and at last out across immensity to the stars. And when he has conquered all the deeps of space and all the mysteries of time, still he will be beginning.
