There is a mystery at the heart of Plato's Parmenides. In the first part, Parmenides criticizes what is widely regarded as Plato's mature theory of Forms, and in the second, he promises to explain how the Forms can be saved from these criticisms. Ever since the dialogue was written, scholars have struggled to determine how the two parts of the work fit together. Did Plato mean us to abandon, keep, or modify the theory of Forms, on the strength of Parmenides' criticisms? Samuel Rickless offers something that has never been done before: a careful reconstruction of every argument in the dialogue. He concludes that Plato's main aim was to argue that the theory of Forms should be modified by allowing that forms can have contrary properties. To grasp this is to solve the mystery of the Parmenides and understand its crucial role in Plato's philosophical development.

Samuel C. Rickless presents a novel interpretation of the thought of George Berkeley. In A Treatise Concerning the Principles of Human Knowledge (1710) and Three Dialogues Between Hylas and Philonous (1713), Berkeley argues for the astonishing view that physical objects (such as tables and chairs) are nothing but collections of ideas (idealism); that there is no such thing as material substance (immaterialism); that abstract ideas are impossible (anti-abstractionism); and that an idea can be like nothing but an idea (the likeness principle). It is a matter of great controversy what Berkeley's argument for idealism is and whether it succeeds. Most scholars believe that the argument is based on immaterialism, anti-abstractionism, or the likeness principle. In Berkeley's Argument for Idealism, Rickless argues that Berkeley distinguishes between two kinds of abstraction, 'singling' abstraction and 'generalizing' abstraction; that his argument for idealism depends on the impossibility of singling abstraction but not on the impossibility of generalizing abstraction; and that the argument depends neither on immaterialism nor the likeness principle. According to Rickless, the heart of the argument for idealism rests on the distinction between mediate and immediate perception, and in particular on the thesis that everything that is perceived by means of the senses is immediately perceived. After analyzing the argument, Rickless concludes that it is valid and may well be sound. This is Berkeley's most enduring philosophical legacy.

Just War theory - as it was developed by the Catholic theologians of medieval Europe and the jurists of the Renaissance - is a framework for the moral and legal evaluation of armed conflicts. To this day, Just War theory informs the judgments of ethicists, government officials, international lawyers, religious scholars, news coverage, and perhaps most importantly, the public as a whole. The influence of Just War theory is as vast as it is subtle - we have been socialized into evaluating wars largely according to the principles of this medieval theory, which, according to the eminent philosopher David Rodin, is "one of the few basic fixtures of medieval philosophy to remain substantially unchallenged in the modern world". Some of the most basic assumptions of Just War Theory have been dismantled in a barrage of criticism and analysis in the first dozen years of the 21st century. "The Ethics of War" continues and pushes past this trend. This anthology is an authoritative treatment of the ethics and law of war by both the eminent scholars who first challenged the orthodoxy of Just War theory, as well as by new thinkers. The twelve original essays span both foundational and topical issues in the ethics of war, including an investigation of: whether there is a "greater-good" obligation that parallels the canonical lesser-evil justification in war; the conditions under which citizens can wage war against their own government; whether there is a limit to the number of combatants on the unjust side who can be permissibly killed; whether the justice of the cause for which combatants fight affects the moral permissibility of fighting; whether duress ever justifies killing in war; the role that collective liability plays in the ethics of war; whether targeted killing is morally and legally permissible; the morality of legal prohibitions on the use of indiscriminate weapons; the justification for the legal distinction between directly and indirectly harming civilians; whether human rights of unjust combatants are more prohibitive than have been thought; the moral repair of combatants suffering from PTSD; and the moral categories and criteria needed to understand the proper justification for ending war.

The Oxford Handbook of Berkeley is a compendious examination of a vast array of topics in the philosophy of George Berkeley (1685-1753), Anglican Bishop of Cloyne, the famous idealist and most illustrious Irish philosopher. Berkeley is best known for his denial of the existence of material substance and his insistence that the only things that exist in the universe are minds (including God) and their ideas; however, Berkeley was a polymath who contributed to a variety of different disciplines, not well distinguished from philosophy in the eighteenth century, including the theory and psychology of vision, the nature and functioning of language, the debate over infinitesimals in mathematics, political philosophy, economics, chemistry (including his favoured panacea, tar-water), and theology. This volume includes contributions from thirty-four expert commentators on Berkeley's philosophy, some of whom provide a state-of-the-art account of his philosophical achievements, and some of whom place his philosophy in historical context by comparing and contrasting it with the views of his contemporaries (including Mandeville, Collier, and Edwards), as well as with philosophers who preceded him (such as Descartes, Locke, Malebranche, and Leibniz) and others who succeeded him (such as Hume, Reid, Kant, and Shepherd).
