The concept of an "idea" played a central role in 17th-century theories of mind and knowledge, but philosophers were divided over the nature of ideas. This book examines an important, but little-known, debate on this question in the work of Leibniz, Malebranche, and Descartes. Looking closely at the issues involved, as well as the particular context in which the debate took place, Jolley demonstrates that the debate has serious implications for a number of major topics in 17th-century philosophy.

This book is a general introduction to the philosophy of John Locke, one of the most influential thinkers in modern times. Nicholas Jolley aims to show the fundamental unity of Locke's thought in his masterpiece, the Essay Concerning Human Understanding. In this work Locke advances a coherent theory of knowledge; as against Descartes he argues that knowledge is possible to the extent that it concerns essences which are constructions of the human mind.

A remarkable thinker, Gottfried Leibniz made fundamental contributions not only to philosophy, but also to the development of modern mathematics and science. At the center of Leibniz's philosophy stands his metaphysics, an ambitious attempt to discover the nature of reality through the use of unaided reason. This volume provides a systematic and comprehensive account of the full range of Leibniz's thought, exploring the metaphysics in detail and showing its subtle and complex relationship to his views on logic, language, physics, and theology.

In this text, the most systematic exposition of Malebranche's philosophy, he presents clear and comprehensive statements of his two best-known contributions to metaphysics and epistemology, namely, the doctrines of occasionalism and vision in God. This edition presents a translation of the text that is clear, readable and more accurate than any of its predecessors, together with an introduction that analyzes Malebranche's central teachings and explains the importance of the Dialogues in the context of seventeenth-century philosophy.

Causality and Mind presents seventeen of Nicholas Jolley's essays on early modern philosophy, which focus on two main themes. One theme is the continuing debate over the nature of causality in the period from Descartes to Hume. Jolley shows that, despite his revolutionary stance, Descartes did no serious re-thinking about causality; it was left to his unorthodox disciple Malebranche to argue that there is no place for natural causality in the new mechanistic picture of the physical world. Several essays explore critical reactions to Malebranche's occasionalism in the writings of Leibniz,...

In seventeenth-century philosophy the mind-body problem and the nature of personal immortality were two of the most controversial and sensitive issues. Nicholas Jolley seeks to show that these issues are more prominent in Locke's philosophy than has been realized. He argues further that Locke takes up unorthodox positions in both cases. Although Locke's official stance on the mind-body problem is agnostic, in places he presents arguments that, taken together, amount to a significant case for a weak form of materialism. Locke also seeks to show that the solution to the mind-body problem is...

Nicholas Jolley argues that Locke's three greatest works - An Essay Concerning Human Understanding, Two Treatises of Government, and Epistola de Tolerantia - are unified by a concern to promote the cause of religious toleration. Jolley shows how Locke uses the principles of his theory of knowledge to criticize religious persecution.
