As one of the most important ethicists to emerge since the Second World War, Alan Gewirth continues to influence philosophical debates concerning morality. In this ground-breaking book, Gewirth's neo-Kantianism, and the communitarian problems discussed, form a dialogue on the foundation of moral theory. Themes of agent-centered constraints, the formal structure of theories, and the relationship between freedom and duty are examined along with such new perspectives as feminism, the Stoics, and Sartre. Gewirth offers a picture of the philosopher's theory and (...) its applications, providing a richer, more complete critical assessement than any which has occurred to date. (shrink)

Philosophy: The Big Questions occupies a unique position among introductory texts in philosophy. Designed for a single-semester introductory course in philosophy, it includes both classic readings in philosophy and newer articles. Presents, in one volume, canonical and contemporary works in ethics, metaphysics, philosophy of religion, and epistemology. Topics discussed include knowledge, religion, freedom, morality, and the meaning of life. Serves as a comprehensive and compelling introduction to philosophy. Together with traditional readings it also presents non-traditional, feminist eadings from a continental (...) perspectives. (shrink)

I advance a type of conceptualist argument for substance dualism – minimally, the view that we are spiritual substances that have bodies – based on the understandability of what it would be for something to be a spirit, e.g. what it would be for God to be a spirit. After presenting the argument formally, I clarify and defend its various premises with a special focus on what I take to be the most controversial one, namely, if thinking matter is metaphysically (...) possible, it is not the case that we have a distinct positive concept of God's being a divine spirit.

There are two tasks for any adequate philosophy of mind: (1) articulate one’s position and explain why dualism is the commonsense view; (2) defend one’s position. I believe that there is an argument that simultaneously satisfies both desiderata in a non–ad hoc way and, thus, the argument can thereby claim the virtue of theoretical simplicity in its favor. In what follows, I shall present the argument and defend its most crucial premise, respond to three criticisms that have been raised against (...) it, and draw out one dialectical implication of the argument.

The appearance of consciousness in the world is an amazing and puzzling fact in its own right. Indeed, consciousness is one of the most mystifying features of the cosmos. The unity of consciousness is something that cries out for analysis and explanation as well. This chapter provides a way of relating the three types of unity: objectual phenomenal unity; subject phenomenal unity; and subsumptive phenomenal unity. According to Tim Bayne and David Chalmers, this sort of unity is irrelevant for investigating (...) the nature of consciousness' unity because it is trivially true by definition and tells us nothing about consciousness. Many thinkers, including Bayne himself, believe there is no self or subject that unifies consciousness. Bayne's position amounts to a bunch of mere assertions that allow him to avoid an obvious solution: substance dualism. (shrink)

For some time now, Nancey Murphy has been a major voice on behalf of a certain form of Christian physicalism. This is a part of her project of reconciling science with Christian faith. In what follows, I shall state and criticize the three central components of her Christian physicalism, followed by a presentation of a dualist alternative along with a clarification of its advantages over Murphy-style physicalism.

While most philosophers agree that libertarian agency and naturalism are incompatible, few attempts have been offered to spell out in some detail just why this is the case. My purpose in this article is to fill this gap in the literature by expanding on and clarifying the connection between naturalism as it is widely understood today and the rejection of libertarian agency. To accomplish this end I begin by clarifying different forms of libertarian agency and identity the key philosophical components (...) that constitute libertarian agency per se. Second, three different aspects of contemporary scientific naturalism are analyzed and the relations among them clarified: the naturalist epistemic attitude, etiology, and ontology. This is followed by a presentation of six arguments for the claim that libertarian agency should be rejected by advocates of scientific naturalism. Finally, I criticize a recent attempt by Randolf Clarke to reconcile libertarian agency and scientific naturalism. (shrink)

1. The Commentariolum Petitionis is not in the Codex Mediceus of Cicero's correspondence with his brother Quintus, but it appears at the end of the letters to Quintus in the other manuscripts. It starts in the normal manner of a letter and is, or purports to be, a collection of tips on canvassing set in the particular context of M. Cicero's consular candidature in 64: a composition of his brother Quintus. It is printed as no. 12 in Tyrrell and Purser's (...) collection of Cicero's Letters. (shrink)

In an attempt to discover the properties of the nervous system, we imagined the conditions under which a machine would be able to construct its own program and from which emerged the model of Self Modifying Automata. We demonstrated the unicity of the SMA model, their convergence in a p-cycle and, in this case, the SELFREFERENCE of a stabilised SMA, their adaptability when connected to a deterministic world. The SMA reaches its p-cycle very quickly and the most probable length of (...) the -cycle is 1. (shrink)

Very often, living beings seem able to change their functioning when external conditions vary. In order to study this property, we have devised abstract machines whose internal organisation changes whenever the external conditions vary. The internal organisations of these machines, are as simple as possible, functions of discrete variables. We call such machines self-modifying automata.These machines stabilise after any transient steps when they go indefinitely through a loop called p-cycle or limit cycle of length p. More often than not, the (...) p in the cycle is equal to one and the cycle reduces to a fixed point. (shrink)

One of the most important features of living beings that seems universal is perhaps their ability to be modified in a functional way.In order to modelize this characteristic, we designed automata with a finite number of instantaneous internal descriptions, with input(s) and output(s) and which are able to be functionally modified.

I criticize the view that top-down causation is a proper model for depicting and justifying belief in mental causation. When properly interpreted, I believe that there are no clear examples of top-down causation, and there is a persuasive case against it. In order to defend these claims, I, first, clarify three preliminary considerations; second, undermine alleged examples of top-down causation; third, present a case for why there is no top-down mental causation; fourth, explain an important option for moving forward in (...) preserving what we all know to be the case—that mental causation is real.

I present and clarify one form of the modal argument for substance dualism, and go on to state and provide defeaters for five of the major arguments raised against the modal argument as a whole. I do not provide an unabridged defence of the modal argument. Instead, I focus on a range of defeaters scattered throughout the literature that are raised against the modal argument. In my view, these have not been gathered in one place and freshly evaluated. Accordingly, my (...) limited purpose is to fill this lacuna. Thus, I present a representative version of the modal argument to set the context for what follows. Next, I clarify and critique the five major objections directed at the modal argument in general.

Hume fully recognised, and partially explained, the role of inductions from single experiments in human knowledge - something his Scottish critics, and some more recent ones, failed to understand. Those inferences, he maintains, depend on the use of a Newtonian rule and the removal of superfluous circumstances. But that rule is not sufficient, and Hume never stated the exact conditions of this removal. We should distinguish between survey and experience in his philosophy, to understand how experience of conjunctions where inductive (...) knowledge has accumulated, in uniform or regular classes or sets of phenomena, may produce cognitive situations when once is enough - without relying on any mysterious innate principles.

Steve Cowan had criticized my defense of theistic science on four grounds: (1) my critique of compatibilism attacks a straw man; (2) libertarianism cannot meet some of the conditions for responsible action; (3) attributing libertarian agency to God has the unacceptable implication that God can do evil; and (4) we don’t need libertarianism to provide a model of divine actions sufficient to justify the scientific detectability of miracles. I clarify and respond to these points in the order listed and conclude (...) that Cowan’s critique fails. (shrink)

This article reflects on three issues: the past twenty years of the Evangelical Philosophical Society, ideas for EPS's future, and some words of advice to my younger EPS colleagues. Regarding, I identify four values that were central to the rebirth of the EPS and that have guided us for twenty years. Regarding, I issue a warning and a challenge. Regarding, I provide three words of advice for keeping us on course.

In a previous article, I argue that on the assumption that God exercises libertarian agency, a primary causal divine miracle could, in principle, leave a scientifically detectable gap in the natural world. In a subsequent publication, Evan Fales offered a critique of my argument and this article is my rejoinder. I justify my employment of Divine libertarian agency and respond to Fales’s two, closely-related questions: How much energy could one add to a room by making a lot of decisions? Would (...) the increase in energy be measurable? (shrink)

The progress in artificial intelligence enables us to conceive adaptive systems whose characteristics are nearer and nearer to those of living beings. These characteristics though depend on ingenious choices by the designer of these systems: Initial conditions, parameters, optimisation functions, gradient and measure of fitness within the environment. Nevertheless, in living systems which are non-finalist, there are no programmers or designers to conceive of such ingenious choices. Our paper “Self-Programming Machines (I)” presents a non-finalist model since initial states and functions (...) are randomly chosen at the beginning and once and for all. In spite of the fact that they are non-finalist, these machines always stabilise at fixed points when they are connected to an external process. (shrink)

Of the early Roman historians who wrote in Greek, A. Postumius Albinus was not necessarily alone in realizing that his Greek was not the best Greek; while, on the other hand, Cato and those who followed the new fashion of writing in Latin would have resented, we may assume, could they have foreknown, the statement of Q,. Catulus in Cicero's De Oratore that they had no literary or rather ‘oratorical’ merit; though Cato might have approved Catulus' caustic comment on Roman (...) historical writing, ‘Satis est non esse mendacem’. That an historian should not, consciously and deliberately, lie all second-century historians would no doubt have agreed; and they would have endorsed Polybius' condemnation of masquerading as history in a story whose falseness was self-evident, because it assumed, on the part of the young sons of senators at Rome, a gravitas such as no young boy could possibly possess.

We isolate two abstract determinacy theorems for games of length $\omega_1$ from work of Neeman and use them to conclude, from large-cardinal assumptions and an iterability hypothesis in the region of measurable Woodin cardinals thatif the Continuum Hypothesis holds, then all games of length $\omega_1$ which are provably $\Delta_1$ -definable from a universally Baire parameter are determined;all games of length $\omega_1$ with payoff constructible relative to the play are determined; andif the Continuum Hypothesis holds, then there is a model of (...) ${\mathsf{ZFC}}$ containing all reals in which all games of length $\omega_1$ definable from real and ordinal parameters are determined.

It is shown that the determinacy of $G_{\delta \sigma }$ games of length $\omega ^2$ is equivalent to the existence of a transitive model of ${\mathsf {KP}} + {\mathsf {AD}} + \Pi _1\textrm {-MI}_{\mathbb {R}}$ containing $\mathbb {R}$. Here, $\Pi _1\textrm {-MI}_{\mathbb {R}}$ is the axiom asserting that every monotone $\Pi _1$ operator on the real numbers has an inductive fixpoint.

We characterize the determinacy of $F_\sigma $ games of length $\omega ^2$ in terms of determinacy assertions for short games. Specifically, we show that $F_\sigma $ games of length $\omega ^2$ are determined if, and only if, there is a transitive model of ${\mathsf {KP}}+{\mathsf {AD}}$ containing $\mathbb {R}$ and reflecting $\Pi _1$ facts about the next admissible set.As a consequence, one obtains that, over the base theory ${\mathsf {KP}} + {\mathsf {DC}} + ``\mathbb {R}$ exists,” determinacy for $F_\sigma $ (...) games of length $\omega ^2$ is stronger than ${\mathsf {AD}}$, but weaker than ${\mathsf {AD}} + \Sigma _1$ -separation.
