Alexander the Great sat down and cried, somewhere in the middle of India, I think, because there were no more new worlds to conquer. What a silly man he was. There he sits sniveling, halfway to China! A conqueror. Conquistadores, always running into new worlds, and quickly running out of them. Conquest is not finding, and it is not making. Our culture, which conquered what is called the New World, and which sees the world of nature as an adversary to be conquered: look at us now. Running out of everything. – Ursula K. Le Guin, World-Making (1981) in Dreams Must Explain Themselves
