Adding more people causes problems. But people are also the means to solve these problems. The main fuel to speed the world’s progress is our stock of knowledge; the brakes are our lack of imagination and unsound social regulations of these activities. The ultimate resource is people—especially skilled, spirited, and hopeful young people endowed with liberty—who will exert their wills and imaginations for their own benefits, and so inevitably they will benefit the rest of us as well.

Not understanding the process of a spontaneously-ordered economy goes hand-in-hand with not understanding the creation of resources and wealth.

The main fuel to speed the world's progress is our stock of knowledge, and the brake is our lack of imagination.

Progress toward a more abundant material life does not come like manna from heaven. . . . My message certainly is not one of complacency. In this I agree with the doomsayers: our world needs the best efforts of all humanity to improve our lot.

Because we can expect future generations to be richer than we are, no matter what we do about resources, asking us to refrain from using resources now so that future generations can have them later is like asking the poor to make gifts to the rich.

We now have in our hands—really, in our libraries—the technology to feed, clothe, and supply energy to an ever-growing population for the next seven billion years.
