Major Works and Enduring Influence
Religion and the Decline of Magic: Studies in Popular Beliefs in Sixteenth- and Seventeenth-Century England (1971): This monumental study delves into the transition from a pervasive magical worldview to a more rational and scientific outlook in early modern England. Thomas meticulously examines the widespread belief in astrology, witchcraft, divination, and the efficacy of charms, alongside the complex role of the Church in both accommodating and challenging these practices. The book's innovative use of an anthropological lens to understand historical phenomena was revolutionary, demonstrating how popular beliefs, rituals, and superstitions permeated all levels of society, from peasant to peer. It remains a foundational text for understanding the cultural and religious history of the period, exploring how social change and evolving intellectual currents gradually led to the marginalization of magical thought.
Man and the Natural World: A History of the Modern Sensibility (1983): This highly influential work explores the evolving attitudes of human beings towards animals and plants in Britain between the 16th and 18th centuries. Thomas traces the emergence of a distinctive "modern sensibility" towards nature, examining topics such as the growth of vegetarianism, the development of natural history as a scientific discipline, the rise of pet-keeping, and early concerns about environmental degradation. The book masterfully illustrates how cultural, economic, and intellectual changes reconfigured the relationship between humanity and the natural environment, laying some of the conceptual groundwork for modern environmental thought and conservation movements. It is considered a pioneering work in environmental history.
