I. Essays on TheodicyTheodicy is a branch of philosophy that seeks to justify the goodness of God in the face of the existence of evil., etc. Parts II and III.
II. Abridgment of the Controversy reduced to formal arguments. In this section, Leibniz translates his theological arguments into "syllogisms"—the rigid, logical structures used by scholars to test the validity of a claim.
III. Reflections on the dispute conducted between Dr. Bramhall, Bishop of Londonderry, and Mr. Hobbes, concerning Liberty, Necessity, and Chance. John Bramhall (1594–1663) and Thomas Hobbes (1588–1679) were famous rivals; their debate focused on whether humans have "free will" or if all actions are predetermined by "necessity."
IV. Remarks on the Book of the Origin of Evil, recently published in London. Leibniz is here critiquing "De Origine Mali" (1702), a significant work by William King, the Archbishop of Dublin.
V. The Cause of God defended by His Justice, etc. original: "Causa Dei asserta per Justitiam ejus"; this is a formal Latin treatise by Leibniz that provides a systematic legal and theological defense of divine providence.
