This scholarly study examines Cornelius Agrippa within the intellectual upheavals of the Renaissance. Charles Nauert treats Agrippa not only as a biographical figure but as a revealing case through which to understand the tensions, contradictions, and transformations of early modern European thought. The book situates Agrippa’s writings and career amid the competing currents of humanism, theology, natural philosophy, magic, rhetoric, and skepticism that shaped Renaissance intellectual life. By tracing the development of his ideas and the contexts in which they emerged, the work explores how a learned figure could embody both the ambitions and the crises of an age marked by changing views of knowledge, authority, and the human place in the world. Aimed at readers interested in Renaissance history, early modern philosophy, and the history of ideas, the study offers a detailed account of Agrippa’s significance as a thinker whose work reflects the instability and creativity of Renaissance culture.
