About the author
American economist (1932–1998), professor at the University of Maryland and a senior fellow at the Cato Institute. A onetime believer in overpopulation doom who reversed his views, Simon became the leading optimist on resources and population; his famous 1980 wager with Paul Ehrlich, which he won, made him an icon of the cornucopian position.
Synopsis
Simon assembles long-run data showing that, over time, raw materials have grown cheaper, food more abundant, and life expectancy longer, even as population rose. He argues that human creativity, channeled by markets and prices, repeatedly overcomes apparent resource limits, and that population growth, far from a catastrophe, is the engine of progress. He won a famous wager with the ecologist Paul Ehrlich over whether key resource prices would rise or fall.
Core passage idea
Paraphrase · Modern copyrighted workSimon argues that the 'ultimate resource' is human ingenuity itself — that as scarcity raises prices, people innovate and substitute, so that resources effectively expand, and more people mean more minds to solve problems.
By making human creativity the master resource, Simon inverts the Malthusian frame: scarcity is the spur to abundance, not the prelude to collapse. The claim is the core of techno-optimist and market-environmental thought — and the sharpest challenge to the limits-to-growth worldview.
To avoid a bubble
Pair directly with The Limits to Growth and with climate and ecological economists who argue Simon's faith in substitution and innovation ignores irreversible thresholds, ecosystem collapse, and the carbon problem that markets have not solved.
Reading note
Read it as the cornucopian answer to Limits to Growth and the Malthusian tradition; the chapters on resource prices and population are the core. Pair with ecological critics to judge where innovation can — and cannot — overcome limits.
