We live in an age in which we are repeatedly reminded – by scientists, by the media, by popular culture – of the looming threat of mass extinction. We're told that human activity is currently producing a sixth mass extinction, perhaps of even greater magnitude than the five previous geological catastrophes that drastically altered life in the past. Indeed, there is a very real concern that the human species may itself be poised to go the way of the dinosaurs, victims of the most recent mass extinction some 65 million years ago.
How we interpret the causes, consequences, and moral imperatives of extinction is deeply embedded in the cultural values of any given historical moment. And as David Sepkoski reveals, the history of scientific ideas about extinction over the past two hundred years – as both a past and current process – are implicated in major changes in the way Western society has approached biological and cultural diversity. It seems self-evident to most of us that diverse ecosystems and societies are intrinsically valuable, but the current fascination with diversity is a relatively recent phenomenon. In fact, the way we value diversity depends crucially on our sense that it is precarious – that it is something actively threatened, and that its loss could have profound consequences. In Catastrophic Thinking, Sepkoski uncovers how and why we learned to value diversity as a precious resource at the same time as we learned to think catastrophically about extinction.
"In his wise and meticulously argued new book, Sepkoski explains why every era gets the dinosaur story it deserves, how the threat to biodiversity helped fashion cultural diversity into an ideal, and why extinction has become personal to each and every one of us. An urgent and brilliant exemplar of history of science at its very best, Catastrophic Thinking beautifully shows that the ways we construct the past are always reflections of our hopes and fears for the future."

"An authoritative, compelling, and insightful account of how biological and cultural diversity has come to be so highly prized in contemporary Western society. This is a definitive history of the cultural and scientific developments, especially in paleontology, that have helped forge our sense of the modern biodiversity crisis. Lucid, historically sweeping, and accessible, Sepkoski's book ably reconstructs key aspects of the larger culture in which ideas about extinction, catastrophe, and diversity emerged."
