Leonardo da Vinci was a brilliant artist, scientist, engineer, mathematician, architect, inventor, and even musician—the archetypal Renaissance man. But he was also a profoundly modern man. Not only did Leonardo invent the empirical scientific method over a century before Galileo and Francis Bacon, but Capra’s decade-long study of Leonardo’s fabled notebooks reveals that he was a systems thinker centuries before the term was coined. At the very core of Leonardo’s science, Capra argues, lies his persistent quest for understanding the nature of life. His science is a science of living forms, of qualities and patterns, radically different from the mechanistic science that emerged 200 years later.
