Daniel Quinn said this quote

There's nothing fundamentally wrong with people. Given a story to enact that puts them in accord with the world, they will live in accord with the world. But given a story to enact that puts them at odds with the world, as yours does, they will live at odds with the world. Given a story to enact in which they are the lords of the world, they will ACT like lords of the world. And, given a story to enact in which the world is a foe to be conquered, they will conquer it like a foe, and one day, inevitably, their foe will lie bleeding to death at their feet, as the world is now.

~ Daniel Quinn

The premise of the Taker story is 'the world belongs to man'. … The premise of the Leaver story is 'man belongs to the world'.

~ Daniel Quinn

Do you see the slightest evidence anywhere in the universe that creation came to an end with the birth of man? Do you see the slightest evidence anywhere out there that man was the climax toward which creation had been straining from the beginning? ...Very far from it. The universe went on as before, the planet went on as before. Man's appearance caused no more stir than the appearance of jellyfish.

~ Daniel Quinn

You're captives of a civilizational system that more or less compels you to go on destroying the world in order to live. … You are captives—and you have made a captive of the world itself. That's what's at stake, isn't it?—your captivity and the captivity of the world.
