We are very happy today to be able to publish this exclusive excerpt from Jessica Riskin’s new book, The Power of Life: The Invention of Biology and the Revolutionary Science of Jean-Baptiste Lamarck (Riverhead Books, March 2026). Jessica teaches history and philosophy of science at Stanford University. Many of us are in agreement that her previous book, The Restless Clock (Chicago, 2016) is among the best treatments of the natural-philosophical problem of life in early modern Europe ever written, and deserves to be considered a new classic. It is fitting that she should turn her attention next to Lamarck (1744-1829) — amply memorialized in statues and lecture halls in France and widely characterized here as the “founder of the theory of evolution”, even as his role in the history of science is mostly downplayed or dismissed in the Anglosphere. This dismissiveness is especially regrettable, given that some of Lamarck’s ideas have been positively reassessed in recent years by scientists working in such fields as epigenetics and developmental plasticity theory. It is to be hoped that Jessica’s book will help to bring about a deeper and more complete picture of this crucial figure. Jill Lepore has said of The Power of Life that it is a “truly remarkable achievement, at once a delightfully wry and wildly entertaining biography of Jean-Baptiste Lamarck and a riveting intellectual history.” Order your copy today. —The Editors

From the garret window of the room where Jean-Baptiste Lamarck lived when he first moved to Paris in his mid-twenties, around 1770, he could see nothing but clouds and sky. The clouds therefore became his companions and source of entertainment. Watching them, he began to notice how they formed, gathered and dispersed. They didn’t behave randomly, he observed, but exhibited types and patterns. He began to watch more carefully, and in this way, he became the first person to classify the clouds, producing a veritable cloud atlas for his first presentation to the Academy of Sciences in 1777. He divided clouds into five types: (1) veiled (en voile), (2) gathered (attroupés), (3) dappled (pommelés), (4) sweeping (en balayures), and (5) grouped (groupé). But Lamarck became busy, first with the study of botany and then with his new position at the National Museum of Natural History, created during the French Revolution, the wonderfully named Chair in Insects and Worms. He waited twenty-five years before actually publishing his classification of clouds, finally including it in his meteorological yearbook for Year Ten of the Revolution (1802) – the same year in which he coined the word “Biologie.”
