Scientia is the term that early modern philosophers applied to a certain kind of demonstrative knowledge, the kind whose starting points were appropriate first principles. In pre-modern philosophy, too, scientia was the name for demonstrative knowledge from first principles. But pre-modern and early modern conceptions differ systematically from one another. This book offers a variety of glimpses of this difference by exploring the works of individual philosophers as well as philosophical movements and groupings of the period. Some of the figures are transitional, falling neatly on neither side of the allegiances usually marked by the scholastic/modern distinction. Among the philosophers whose views on scientia are surveyed are Hobbes, Descartes, Spinoza, Gassendi, Locke, and Jungius. The contributors are among the best-known and most influential historians of early modern philosophy.

The Cambridge Platonists were defenders of tolerance in the political as well as the moral sphere ; they held that practical j u d g e m e n t came down in the last instance to individual conscience ; and they laid the foundations of our modern conceptions of conscience and liberty. But at the same time they ma intained the existence of eternal truths , and of a Good-in-itself , identical with Truth and Being, refusing to admit that freedom of conscience i m p li e d moral relativism. They were critics of dogmatism, and of the sectarian notion of "enthusiasm" as a source of illumination , on the grounds that both were disruptive of social harmony; they pleaded the cause of reason , in the hope that it could become the foundation of all human knowledge . Yet , for all that , they ma intained that a certain sort of mystical illumination lay at the heart of all true thought , and that human reason had validity only in virtue of i t s divine origin . They debated with Des cartes and took a keen interest in his mech- ism and his dualism ; they brought the atomistic theories of Democritus back into repute; and they sought to provide a detailed account of the causality link ing all phenomena.
