Through a collection of works from key thinkers in natural philosophy, the second edition of The Scientific Background to Modern Philosophy illuminates the central role scientific writing played in developing modern philosophical thought. This revised and expanded edition includes many new translations and incorporates works by foundational eighteenth- and nineteenth-century thinkers not in the first edition, including selections from works by Jean-Baptiste, le Rond d'Alembert, Denis Diderot, milie Du Chtelet, Jean-Jacques Rousseau, Joseph Priestley, Immanuel Kant, Carl Linnaeus, William Paley, and Charles Robert Darwin. These new additions provide students with a more comprehensive understanding of the scientific context in which the major philosophical works of the modern era were written and complement the selections from works by Nicolaus Copernicus, Francis Bacon, Galileo Galilei, Ren Descartes, Robert Boyle, Christiaan Huygens, and Isaac Newton that are retained from the first edition.
