"Translated with an uncanny sense for the overall point of Augustine's doctrine. In short, a very good translation. The Introduction is admirably clear." --Paul Vincent Spade, Indiana University.

This book traces the development of formal logic from its origins inancient Greece to the present day. The authors first discuss the work oflogicians from Aristotle to Frege, showing how they were influenced by thephilosophical or mathematical ideas of their time. They then examinedevelopments in the present century.

This essay challenges the widely accepted principle that a person is morally responsible for what he has done only if he could have done otherwise. The author considers situations in which there are sufficient conditions for a certain choice or action to be performed by someone, So that it is impossible for the person to choose or to do otherwise, But in which these conditions do not in any way bring it about that the person chooses or acts as he (...) does. In such situations the person may well be morally responsible for what he chooses or does despite his inability to choose or to do otherwise. Finally the author considers certain suggestions for revising the principle he rejects or for replacing it with a principle of an altogether different kind. (shrink)

This long-awaited book replaces Hughes and Cresswell's two classic studies of modal logic: _An Introduction to Modal Logic_ and _A Companion to Modal Logic_. _A New Introduction to Modal Logic_ is an entirely new work, completely re-written by the authors. They have incorporated all the new developments that have taken place since 1968 in both modal propositional logic and modal predicate logic, without sacrificing tha clarity of exposition and approachability that were essential features of their earlier works. The book takes (...) readers from the most basic systems of modal propositional logic right up to systems of modal predicate with identity. It covers both technical developments such as completeness and incompleteness, and finite and infinite models, and their philosophical applications, especially in the area of modal predicate logic.

Several years ago I came across a marvelous little paper in which Hector-Neri Castaneda shows that standard versions of act utilitarian l ism are formally incoherent. I was intrigued by his argument. It had long seemed to me that I had a firm grasp on act utilitarianism. Indeed, it had often seemed to me that it was the clearest and most attractive of normative theories. Yet here was a simple and relatively uncontrover sial argument that showed, with only some trivial (...) assumptions, that the doctrine is virtually unintelligible. The gist of Castaneda's argument is this: suppose we understand act utilitarianism to be the view that an act is obligatory if and only if its utility exceeds that of each alternative. Suppose it is obligatory for a certain person to perform an act with two parts - we can call it 'A & B'. Then, obviously enough, it is also obligatory for this person to perform the parts, A and B. If act utilitarianism were true, we appar ently could infer that the utility of A & B is higher than that of A, and higher than that of B (because A & B is obligatory, and the other acts are alternatives to A & B).

Luis de Molina was a leading figure in the remarkable sixteenth-century revival of Scholasticism on the Iberian peninsula. Molina is best known for his innovative theory of middle knowledge. Alfred J. Freddoso's extensive introductory essay clears up common misconceptions about Molina's theory, defends it against both philosophical and theological objections, and makes it accessible to contemporary readers.

This book investigates what it means, and whether it is coherent, to say that there is a God.

This book discusses and exemplifies the philosophy of religion, or philosophical reflection on central themes of religion.

“The problem of universals” in general is a historically variable bundle of several closely related, yet in different conceptual frameworks rather differently articulated metaphysical, logical, and epistemological questions, ultimately all connected to the issue of how universal cognition of singular things is possible. How do we know, for example, that the Pythagorean theorem holds universally, for all possible right triangles? Indeed, how can we have any awareness of a potential infinity of all possible right triangles, given that we could only (...) see a finite number of actual ones? How can we universally indicate all possible right triangles with the phrase ‘right triangle’? Is there something common to them all signified by this phrase? If so, what is it, and how is it related to the particular right triangles? The medieval problem of universals is a logical, and historical, continuation of the ancient problem generated by Plato's (428-348 B.C.) theory answering such a bundle of questions, namely, his theory of Ideas or Forms.

A good deal of attention has been given in recent philosophy of religion to the question of whether we can sensibly attribute to God a form of knowledge which the 16th-century Jesuit theologian Luis de Molina termed "middle knowledge". Interest in the doctrine has been spurred by a recognition of its intimate connection to certain conceptions of providence, prophecy, and response to petitionary prayer. According to defenders of the doctrine, which I will call "Molinism", the objects of middle knowledge are (...) all the true counterfactuals of the form, 'If C were to occur, then S would freely do A', where C specifies a particular set of circumstances. (Such propositions are usually referred to as "counterfactuals of freedom" - hereafter "CFs".)' I will try to assess the current status of two distinct questions: (1) Are there true CFs? and (2) Could God know true CFs if there are any? Obviously, Molinism must answer both questions affirmatively. Most of the discussion has focused on the first question. I hope to show that this approach has been a dialectical mistake on the part of critics of Molinism, for the difficulties of giving an affirmative answer to question (2) are, I believe, far easier to state clearly and convincingly.

One of the strongest arguments for the incompatibility of divine foreknowledge and human free action appeals to the apparent fixity or necessity of the past. Two leading responses to the argument—Ockhamism, which denies a premiss of the argument, and the so-called “eternity solution”, which holds that strictly speaking God does not have foreknowledge—have both come under attack on similar grounds. Neither response, it is alleged, is adequate to the case of divine prophecy. In this paper I shall first state the (...) argument in question and the two responses to it. I shall then consider objections to these responses, focusing primarily on how they deal with prophecy. (shrink)

"This is an important book, and no one interested in issues which touch on the free will will want to ignore it."--Ethics. In this stimulating and thought-provoking book, the author defends the thesis that free will is incompatible with determinism. He disputes the view that determinism is necessary for moral responsbility. Finding no good reason for accepting determinism, but believing moral responsiblity to be indubitable, he concludes that determinism should be rejected.

Recently, John Fischer has applied Frankfurt’s well-known counter-example to the principle of alternate possibilities to refute the traditional libertarian position which holds that a necessary condition for an agent’s decision (choice) to be free in the sense of freedom required for moral responsibility is that the decision not be causally determined, and that the agent could have avoided making it. Fischer’s argument has consequently led various philosophers to develop libertarian accounts of freedom which try to dispense with the avoidability constraint (...) on freedom. My purpose in this article is to show that Fischer’s attack on traditional libertarianism fails, and, therefore, it is premature to abandon that position. (shrink)

This volume succeeds the same authors' well-known An Introduction to Modal Logic and A Companion to Modal Logic. We designate the three books and their authors NIML, IML, CML and H&C respectively. Sadly, George Hughes died partway through the writing of NIML.

On a Molinist account of creation and providence, not only is there is a complete set of truths about what every possible person would freely do in any possible set of circumstances, but these conditional truths are part of the very explanation of our existence. Robert Adams has recently argued that the explanatory priority of these conditionals undermines libertarian freedom. In the present essay, I take at close look at Adams’ argument and at the Molinist response of Thomas Flint. After (...) showing that Flint’s response is inadequate, I develop what I believe to be a more successful Molinist response to Adams’ argument. Along the way, I seek to provide some insight into the nature of libertarian freedom and the proper interpretation of the much discussed “principle of alternate possibilities.”. (shrink)

This volume contains selections of Ockham's philosophical writings which give a balanced introductory view of his work in logic, metaphysics, and ethics.

WHAT do we mean by saying that a being, God for example, is omniscient? One way of answering this question is to translate ‘God is omniscient’ into some slightly more formalised language than colloquial English, e.g. one with variables of a number of different types, including variables replaceable by statements, and quantifiers binding thes.

This classic, provocative introduction to classical metaphysical questions focuses on appreciating the problems, rather than attempting to proffer answers.

The Molinist doctrine that God has middle knowledge requires that God knows the truth-values of counterfactuals of freedom, propositions about what free agents would do in hypothetical circumstances. A well-known objection to middle knowledge, the grounding objection, contends that counterfactuals of freedom have no truth-value because there is no fact to the matter as to what an agent with libertarian freedom would do in counterfactual circumstances. Molinists, however, have offered responses to the grounding objection that they believe are adequate for (...) maintaining the coherence of middle knowledge. I argue that these responses to the grounding objection are not adequate, and that what I call the ‘generic grounding objection’ still poses a serious challenge to middle knowledge. (shrink)

The conviction ofthe New Testament writers was that there is no salvation apart from Jesus. This orthodox doctrine is widely rejected today because God’s condemnation of persons in other world religions seems incompatible with various attributes of God.Analysis reveals the real problem to involve certain counterfactuals of freedom, e.g., why did not God create a world in which all people would freely believe in Christ and be saved? Such questions presuppose that God possesses middle knowledge. But it can be shown (...) that no inconsistency exists between God's having middle knowledge and certain persons' being damned; on the contrary it can be positively shown that these two notions are compatible.

Some contemporary theologians dismiss the classical discussions of the existence and nature of God as out of step with and unworthy of serious consideration by so-called "modern man." Others contend that even though the historical giants of philosophical theology generally had an intimate acquaintance with Sacred Scripture, their philosophical biases beguiled them unwittingly into forming conceptions of God that are wholly foreign to as well as incompatible with the biblical conception of God. These two distinct lines of criticism sometimes converge (...) in the suggestion that today's philosophical theologians should forsake their old heroes for duly modern ones like Whitehead, Heidegger, and Wittgenstein, whose writings allegedly provide philosophical outlooks more in tune with biblical categories of thought. Just as often, however, we find an attitude of distrust toward any sort of metaphysical reflection on the ostensible theological claims of the Judaeo-Christian tradition--both on the part of those who believe that the Judaeo-Christian myths have at most only ethical and perhaps political significance and on the part of those who believe that metaphysical inquiry invariably distorts theological truths by displacing Sacred Scripture as the foundation of the life of faith. Despite their disagreements, however, all sides concur in assigning little if any systematic importance to traditional philosophical theology. (shrink)

Libertarian treatments of free will face the objection that an uncaused human decision would lack full explanation, and hence violate the principle of sufficient reason. It is argued that this difficulty can be overcome if God, as creator, wills that I decide as I do, since my decision could then be explained in terms of his will, which must be for the best. It is further argued that this view does not make God the author of evil in any damaging (...) sense. Neither does it impugn my freedom. God’s creative activity does not put in place any secondary causes that determine my decision; and his will does not stand as an independent determining condition either, since it is fully expressed in my decision alone.

Joseph Owens presents an introduction to metaphysics designed to develop in the reader a habitus of thinking. Using original Thomistic texts and Etienne Gilson's interpretation of St. Thomas Aquinas, Owens examines the application of metaphysical principles to the issues that arise in a specifically Christian environment. An Elementary Christian Metaphysics focuses on questions of existence and the nature of revealed truths. Following his historical introduction to metaphysics, Owens provides a general investigation of the first principles and causes of being and (...) also a study of knowledge and of the divine nature and attributes in light of natural reason. "Irrespective of one's intellectual genotype, an exposure to the sustained, developmental elucidation of Aquinas' insights executed by an author such as Owens can only enhance any metaphysical approach to reality." --The New Scholastic "An Elementary Christian Metaphysics is intended primarily for undergraduate students as an introduction to metaphysics. . . . The scope of the metaphysical study pursued by Owens includes not only a general investigation of beings but also an analysis of knowledge (epistemology) and of the divine nature, all in light of natural reason." --Studies in Religion Joseph Owens (1908-2005) taught philosophy at the Pontifical Institute of Mediaeval Studies and the University of Toronto for forty years. He is the author of a number of books, including An Interpretation of Existence, also published by the University of Notre Dame Press. (shrink)
