From the ancient astronomers of Babylon and Greece through the revolutionary breakthroughs of Copernicus, Galileo, and Kepler, Koestler chronicles the tortuous, often irrational path by which mankind dismantled its geocentric worldview and replaced it with the heliocentric universe — a process less like deliberate discovery than the unconscious wandering of a sleepwalker navigating in the dark.\n\nWhat sets this work apart is Koestler's penetrating argument that scientific progress is rarely the product of pure reason; instead, it is driven by obsession, mysticism, error, and inspired accident. His prose is vivid and accessible yet intellectually rigorous, weaving biography, philosophy, and the history of science into a seamless and gripping narrative. The portrait of Johannes Kepler alone — a tortured genius wrestling with faith and mathematics — stands as one of the most compelling character studies in popular science writing. A book that will forever change the way you think about the nature of discovery, The Sleepwalkers leaves one wondering: how much of what we call knowledge is truly illumination, and how much is simply a lucky stumble through the dark?\u003c\/p\u003e","brand":"Secondhand Stock","offers":[{"title":"Default Title","offer_id":49269356658907,"sku":"2026200017020-SECONDHAND","price":10.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0523\/7646\/9701\/files\/d8010462-72ac-4861-ad1b-b95a0de6430a.png?v=1788999414","url":"https:\/\/bookgrocer.com\/products\/2026200017020-secondhand-the-sleepwalkers-a-history-of-mans-changing-vision-of-the-universe","provider":"Book Grocer","version":"1.0","type":"link"}
