For more than 600 years, Western civilization has relied on exploration to learn about a wider world and universe. The Great Ages of Discovery details the different eras of Western exploration in terms of its locations, its intellectual contexts, the characteristic moral conflicts that underwrote encounters, and the grand gestures that distill an age into its essence. Historian and MacArthur Fellow Stephen J. Pyne identifies three great ages of discovery in his fascinating new book. The first age of discovery ranged from the early 15th to the early 18th century, sketched out the contours of the globe, aligned with the Renaissance, and had for its grandest expression the circumnavigation of the world ocean. The second age launched in the latter half of the 18th century, spanning into the early 20th century, carrying the Enlightenment along with it, pairing especially with settler societies, and had as its prize achievement the crossing of a continent. The third age began after World War II, and, pivoting from Antarctica, pushed into the deep oceans and interplanetary space. Its grand gesture is Voyager’s passage across the solar system. Each age had in common a galvanic rivalry: Spain and Portugal in the first age, Britain and France—followed by others—in the second, and the USSR and USA in the third. With a deep and passionate knowledge of the history of Western exploration, Pyne takes us on a journey across hundreds of years of geographic trekking. The Great Ages of Discovery is an interpretive companion to what became Western civilization’s quest narrative, with the triumphs and tragedies that grand journey brought, the legacies of which are still very much with us.

The present is a contest between the bright and dark sides of discovery. To avoid being torn apart by its stresses, we need to recognize the fact—and gain courage and wisdom from the past. Age of Discovery shows how. Now is the best moment in history to be alive, but we have never felt more anxious or divided. Human health, aggregate wealth and education are flourishing. Scientific discovery is racing forward. But the same global flows of trade, capital, people and ideas that make gains possible for some people deliver big losses to others—and make us all more vulnerable to one another. Business and science are working giant revolutions upon our societies, but our politics and institutions evolve at a much slower pace. That’s why, in a moment when everyone ought to be celebrating giant global gains, many of us are righteously angry at being left out and stressed about where we’re headed. To make sense of present shocks, we need to step back and recognize: we’ve been here before. The first Renaissance, the time of Columbus, Copernicus, Gutenberg and others, likewise redrew all maps of the world, democratized communication and sparked a flourishing of creative achievement. But their world also grappled with the same dark side of rapid change: social division, political extremism, insecurity, pandemics and other unintended consequences of discovery. Now is the second Renaissance. We can still flourish—if we learn from the first.

The Age of Exploration, which spanned roughly from 1400 to 1550, was the first time in history that European powers—eyeing new trade routes to the East or seeking to establish empires—began actively looking far past their own borders to gain a better understanding of the world and its many resources. The individuals who set out on behalf of the countries they represented came from a variety of backgrounds, and included master navigators such as Christopher Columbus and Ferdinand Magellan—the latter of whom was the first to circle the globe—as well as the often ruthless conquistadors of the New World such as Francisco Pizarro and Hernan Cortes. The exciting and sometimes tragic lives and journeys of these and many others as well as the battles for empire that arose are chronicled in this engaging volume.
