This volume offers a reappraisal of a classic text of European philosophy, Leibniz's 'Theodicy'. New essays from leading scholars open a window on the historical context of the work and give close attention to its subtle and enduring philosophical arguments.

"Theodicy" is a book of philosophy by the German polymath Gottfried Leibniz published in 1710, whose optimistic approach to the problem of evil is thought to have inspired Voltaire's "Candide". Much of the work consists of a response to the ideas of the French philosopher Pierre Bayle, with whom Leibniz carried on a debate for many years. The "Theodicy" tries to justify the apparent imperfections of the world by claiming that it is optimal among all possible worlds. It must be the best possible and most balanced world, because it was created by an all powerful and all knowing God, who would not choose to create an imperfect world if a better world could be known to him or possible to exist. In effect, apparent flaws that can be identified in this world must exist in every possible world, because otherwise God would have chosen to create the world that excluded those flaws. Leibniz distinguishes three forms of evil: moral, physical, and metaphysical. Moral evil is sin, physical evil is pain, and metaphysical evil is limitation. God permits moral and physical evil for the sake of greater goods, and metaphysical evil is unavoidable since any created universe must necessarily fall short of God's absolute perfection.

In the New Essays on Human Understanding, Leibniz argues chapter by chapter with John Locke's Essay Concerning Human Understanding, challenging his views about knowledge, personal identity, God, morality, mind and matter, nature versus nurture, logic and language, and a host of other topics. The work is a series of sharp, deep discussions by one great philosopher of the work of another. Leibniz's references to his contemporaries and his discussions of the ideas and institutions of the age make this a fascinating and valuable document in the history of ideas. The work was originally written in French, and the version by Peter Remnant and Jonathan Bennett, based on the only reliable French edition (published in 1962), first appeared in 1981 and has become the standard English translation. It has been thoroughly revised for this series and provided with a new and longer introduction, a chronology on Leibniz's life and career and a guide to further reading.

Paul Rateau traces the genesis and development of G.W. Leibniz's treatment of the problem of evil, from his earliest writings through the Essays on Theodicy (1710). By investigating Leibniz's early thinking about what evil is and where it comes from, Rateau reveals the deeply original nature of Leibniz's later work and the challenges it raises. Rateau explores the ways in which the Theodicy's theoretical project, which integrates numerous disciplines and various argumentative strategies, informs and is influenced by two more practical aims-justifying the end of denominational divisions between Catholics and Protestants, and inculcating “true piety” in believers. By paying equal attention to both Leibniz's intellectual and personal development, Rateau offers a holistic view of Leibniz's most profound and sophisticated work of philosophy. Rateau shows how the young Leibniz moves from suggesting that the author of evil is God himself to later defending an original theory of necessitarianism (in The Confession of a Philosopher), which makes God the first link in the chain of beings that constitute the world, but which ultimately denies God's responsibility for sin. By examining Leibniz's theoretical development after 1673, he demonstrates how Leibniz comes to a revised framework that forms the basis for the project of theodicy. After having examined the defensive and the doctrinal aspects of the Theodicy, Rateau shows how human freedom can be reconciled with divine freedom in Leibniz's system. Newly translated from the original French edition, Rateau's book offers a novel and important new interpretation of Leibniz and will appeal to scholars both of Leibniz and of early modern thought generally.

Of all the issues in the philosophy of religion, the problem of reconciling belief in God with evil in the world arguably commands more attention than any other. For over two decades, Michael L. Peterson’s The Problem of Evil: Selected Readings has been the most widely recognized and used anthology on the subject. Peterson's expanded and updated second edition retains the key features of the original and presents the main positions and strategies in the latest philosophical literature on the subject. It will remain the most complete introduction to the subject as well as a resource for advanced study. Peterson organizes his selection of classical and contemporary sources into four parts: important statements addressing the problem of evil from great literature and classical philosophy; debates based on the logical, evidential, and existential versions of the problem; major attempts to square God's justice with the presence of evil, such as Augustinian, Irenaean, process, openness, and felix culpa theodicies; and debates on the problem of evil covering such concepts as a best possible world, natural evil and natural laws, gratuitous evil, the skeptical theist defense, and the bearing of biological evolution on the problem. The second edition includes classical excerpts from the book of Job, Voltaire, Dostoevsky, Augustine, Aquinas, Leibniz, and Hume, and twenty-five essays that have shaped the contemporary discussion, by J. L. Mackie, Alvin Plantinga, William Rowe, Marilyn Adams, John Hick, William Hasker, Paul Draper, Michael Bergmann, Eleonore Stump, Peter van Inwagen, and numerous others. Whether a professional philosopher, student, or interested layperson, the reader will be able to work through a number of issues related to how evil in the world affects belief in God.
