This two-volume work, first published in 1843, was John Stuart Mill's first major book. It reinvented the modern study of logic and laid the foundations for his later work in the areas of political economy, women's rights and representative government. In clear, systematic prose, Mill disentangles syllogistic logic from its origins in Aristotle and scholasticism and grounds it instead in processes of inductive reasoning. An important attempt at integrating empiricism within a more general theory of human knowledge, the work constitutes (...) essential reading for anyone seeking a full understanding of Mill's thought. Continuing the discussion of induction, Volume 2 concludes with Book VI, 'On the Logic of the Moral Sciences', in which Mill applies empirical reasoning to human behaviour. A crucial early formulation of his thinking regarding free will and necessity, this book establishes the centrality of 'the social science' to Mill's philosophy. (shrink)

This superb abridgement and annotated translation of Maimonides' monumental work includes discussions of divine language, the scope and limits of human knowledge, cosmological doctrines concerning the creation or eternity of the world, prophecy and providence, the nature and purpose of divine law, and moral and political philosophy.

The Principle of Sufficient Reason says that all contingent facts must have explanation. In this 2006 volume, which was the first on the topic in the English language in nearly half a century, Alexander Pruss examines the substantive philosophical issues raised by the Principle Reason. Discussing various forms of the PSR and selected historical episodes, from Parmenides, Leibnez, and Hume, Pruss defends the claim that every true contingent proposition must have an explanation against major objections, including Hume's imaginability argument and (...) Peter van Inwagen's argument that the PSR entails modal fatalism. Pruss also provides a number of positive arguments for the PSR, based on considerations as different as the metaphysics of existence, counterfactuals and modality, negative explanations, and the everyday applicability of the PSR. Moreover, Pruss shows how the PSR would advance the discussion in a number of disparate fields, including meta-ethics and the philosophy of mathematics. (shrink)

This chapter is a work in applied metaphysics. Recent discussions of monism and metaphysical dependence are deployed to develop a view—the doctrine of divine priority (DDP)—that is a viable alternative to the doctrine of divine simplicity (DDS). DDS and the traditional motivation for it are discussed, then DDP is introduced by way of an analogy involving Jonathan Schaffer’s distinction between two forms of monism. It is argued that DDP is an alternative to DDS by showing that it is consistent with (...) the traditional motivation for the latter view, and argued that DDP is a viable alternative by showing that objections to its peculiar implications rest on assumptions that can reasonably be rejected. In the concluding section, the findings of the main discussion are summarized and DDP’s potential theological import is illustrated with a brief discussion of a possible solution to the Problem of the Trinity it affords.

Doing and Being confronts the problem of how to understand two central concepts of Aristotle's philosophy: energeia and dunamis. While these terms seem ambiguous between actuality/potentiality and activity/capacity, Aristotle did not intend them to be so. Through a careful and detailed reading of Metaphysics Theta, Beere argues that we can solve the problem by rejecting both "actuality" and "activity" as translations of energeia, and by working out an analogical conception of energeia. This approach enables Beere to discern a hitherto unnoticed (...) connection between Plato's Sophist and Aristotle's Metaphysics Theta, and to give satisfying interpretations of the major claims that Aristotle makes in Metaphysics Theta, the claim that energeia is prior in being to capacity and the claim that any eternal principle must be perfectly good.

I argue that the one and only truthmaker is the world. This view can be seen as arisingfrom (i) the view that truthmaking is a relation of grounding holding between true propositions and fundamental entities, together with (ii) the view that the world is the one and only fundamental entity. I argue that this view provides an elegant and economical account of the truthmakers, while solving the problem of negative existentials, in a way that proves ontologically revealing.

Consider a circle and a pair of its semicircles. Which is prior, the whole or its parts? Are the semicircles dependent abstractions from their whole, or is the circle a derivative construction from its parts? Now in place of the circle consider the entire cosmos (the ultimate concrete whole), and in place of the pair of semicircles consider the myriad particles (the ultimate concrete parts). Which if either is ultimately prior, the one ultimate whole or its many ultimate parts?

That being than which a greater cannot be conceived.' This was the way in which the living God of biblical tradition was described by the great Medieval philosophers such as Augustine, Anselm and Aquinas.Contemporary philosophers find much to question, criticise and reject in the traditional analysis of that description. Some hold that the attributes traditionally ascribed to God - simplicity, necessity, immutability, eternity, omniscience, omnipotence, creativity and goodness - are inherently incoherent individually, or mutually inconsistent. Others argue that the divinity (...) described by philosophers cannot be the same as the providential God of revelation.In Perfect Being Theology Katherin A. Rogers defends the traditional approach, considering contemporary criticisms but concluding that the most adequate account of the nature of God should build upon the foundation laid by the Medieval philosophers.Written in a lively and accessible style and offering an important historical perspective, this book covers key areas of contention and many of the major ideas and thinkers from all sides of the debate are included.

Sets of contingent objects, perhaps, are as contingent as their members; but properties, propositions, numbers and states of affairs, it seems, are objects whose non-existence is quite impossible. If so, however, how are they related to God? Suppose God has a nature: a property he has essentially that includes each property essential to him. Does God have a nature? And if he does, is there a conflict between God's sovereignty and his having a nature? How is God related to such (...) abstract objects as properties and propositions? These are the questions I want to explore. - Introduction. (shrink)

Aristotle holds that individual substances are ontologically independent from nonsubstances and universal substances but that non-substances and universal substances are ontologically dependent on substances. There is then an asymmetry between individual substances and other kinds of beings with respect to ontological dependence. Under what could plausibly be called the standard interpretation, the ontological independence ascribed to individual substances and denied of non-substances and universal substances is a capacity for independent existence. There is, however, a tension between this interpretation and the (...) asymmetry between individual substances and the other kinds of entities with respect to ontological independence. I will propose an alternative interpretation: to weaken the relevant notion of ontological independence from a capacity for independent existence to the independent possession of a certain ontological status.

Anselmian theists claim (a) that there is a being than which none greater can be conceived; and (b) that it is knowable on purely—solely, entirely—a priori grounds that there is a being than which none greater can be conceived. In this paper, I argue that Anselmian Theism gains traction by conflating different interpretations of the key description ‘being than which no greater can be conceived’. In particular, I insist that it is very important to distinguish between ideal excellence and maximal (...) possible excellence. At the end of my paper, I illustrate the importance of this distinction by applying my discussion to the recent defence of Anselmian Theism in Nagasawa (Philos Q 58:577–591, 2008). (shrink)

The so-called Anselmian thesis says that God is that than which no greater can be thought. This thesis has been widely accepted among traditional theists and it has for several hundred years been a central notion whenever philosophers debate the existence and nature of God. Proponents of the thesis are often silent, however, about exactly what it means to say that God is that than which no greater can be thought. The aim of this paper is to offer an answer (...) to this question by providing rigorous, systematic models of the Anselmian thesis. The most straightforward model, which I call the “Linear Model,” says that God is that than which no greater can be thought by virtue of occupying the top link in the “great chain of being,” a universal linear ranking of all possible beings. Most contemporary philosophers believe, however, that the Linear Model does not succeed because the notion of the great chain of being is untenable. I therefore explore alternatives to the Linear Model. I argue that what I call the “Extended Radial Model” characterizes the Anselmian thesis correctly, even though the model faces a powerful objection. I argue further that the Linear Model should be taken seriously as a backup option for Anselmian theists because (i) it is not vulnerable to the objection that the Extended Radial Model faces and (ii) what is widely regarded as a knock-down objection to the Linear Model is not as compelling as some have claimed.

Anselmian theists, for whom God is the being than which no greater can be thought, usually infer that he is an omniscient, omnipotent and omnibenevolent being. Critics have attacked these claims by numerous distinct arguments, such as the paradox of the stone, the argument from God's inability to sin, and the argument from evil. Anselmian theists have responded to these arguments by constructing an independent response to each. This way of defending Anselmian theism is uneconomical. I seek to establish a (...) new defence which undercuts almost all the existing arguments against Anselmian theism at once. In developing this defence, I consider the possibility that the Anselmian God is not an omniscient, omnipotent and omnibenevolent being. (shrink)

I display the historical roots of perfect being theology in Greco-Roman philosophy, and the distinctive reasons for Christians to take up a version of this project. I also rebut a recent argument that perfect-being reasoning should lead one to atheism.

According to the doctrine of divine simplicity, God is an absolutely simple being lacking any distinct metaphysical parts, properties, or constituents. Although this doctrine was once an essential part of traditional philosophical theology, it is now widely rejected as incoherent. In this paper, I develop an interpretation of the doctrine designed to resolve contemporary concerns about its coherence, as well as to show precisely what is required to make sense of divine simplicity.

Each volume of this series of companions to major philosophers contains specially commissioned essays by an international team of scholars, together with a substantial bibliography, and will serve as a reference work for students and non-specialists.

Plotinus was the greatest philosopher in the 700-year period between Aristotle and Augustine. He thought of himself as a disciple (...) of Plato, but in his efforts to defend Platonism against Aristotelians, Stoics, and others, he actually produced a reinvigorated version of Platonism that later came to be known as 'Neoplatonism'. In this volume, sixteen leading scholars introduce and explain the many facets of Plotinus' complex system. They place Plotinus in the history of ancient philosophy while showing that he was a founder of medieval philosophy. (shrink)

The so-called "Theology of Aristotle" is a translation of the Enneads of Plotinus, the most important representative of late ancient Platonism. It was produced in the 9th century CE within the circle of al-Kindī, one of the most important groups for the early reception of Greek thought in Arabic. In part because the "Theology" was erroneously transmitted under Aristotle's authorship, it became the single most important conduit by which Neoplatonism reached the Islamic world. It is referred to by such thinkers (...) as al-Fārābī, in an attempt to demonstrate the agreement between Platonism and Aristotelianism, Avicenna, who wrote a set of comments on the text, and later on thinkers of Safavid Persia including Mullā Ṣadrā. Yet the "Theology" is not just a translation. It may in fact more accurately be described as a creative paraphrase, which takes frequent liberties with the source text and even includes whole paragraphs' worth of new material. Adamson's book offers a philosophical interpretation of the changes introduced in the Arabic version. It is argued that these changes were in part intended to show the relevance of Plotinus' thought for contemporary Islamic culture, for instance by connecting the Neoplatonist theory of the First Principle to theological disputes within Islam over the status of God's attributes. At the same time the paraphrase reflects a tendency to harmonize the various strands of Greek thought, so that a critique by Plotinus of Aristotle's theory of the soul is subtly changed into a defense of Aristotle's theory against a possible misinterpretation. The upshot, or so Adamson argues, is that the "Theology" needs to be read as an original philosophical work in its own right, and understood within the context of the ʿAbbāsid era. (shrink)

The argument from contingency for the existence of God is best understood as a request for an explanation of the total sequence of causes and effects in the universe (‘History’ for short). Many puzzles about how there could be such an explanation arise from the assumption that God is being introduced as one more cause prepended to the sequence of causes that (allegedly) needed explaining. In response to this difficulty, this chapter defends three theses. First, it argues that, if the (...) argument from contingency is to succeed, the explanation of History in terms of God must not be a causal explanation; second, that a particular hypothesis about God’s relation to History—that God is what I call the foundational ground of History—is intelligible and explanatory; third and finally, that the explanatory advantages of this hypothesis cannot be had within the confines of naturalism.
