It is shown that the logical truth of instances of the T-schema is incompatible with the formal nature of logical truth. In particular, since the formality of logical truth entails that the set of logical truths is closed under substitution, the logical truth of T-schema instances entails that all sentences are logical truths.

We are grateful for Roy T. Cook's attention to our work in his recent review of our book If A, Then B: How the World Discovered Logic. But Professor Cook leaves two misimpressions that we should like to correct. First, we have never maintained (as he phrases it) that "one's premises must be more certain than the conclusions that follow from them, ignoring the obvious logical fact that, if B logically follows from A, then B is provably at (...) least as probable as A." Instead, we assert that one must be *initially* more certain of one's premises than the conclusions that follow from them; otherwise, we contend, no argument that relies on those premises to prove such a conclusion can be rationally persuasive. On this view, one might still be equally certain of both the premises and the conclusion after being persuaded by the argument, especially in cases where the premises entail the conclusion. By analogy, Aristotle asserts in the Posterior Analytics that the premises of demonstration must be "better known" than the conclusion—meaning, in part, that the premises must be initially more convincing. But this hardly shows that Aristotle thinks that, if A is invoked to demonstrate B, then A and B can never be regarded as equally probable…. (shrink)

One of the main reasons for providing formal semantics for languages is that the mathematical precision afforded by such semantics allows us to study and manipulate the formalization much more easily than if we were to study the relevant natural languages directly. Michael Tye and R. M. Sainsbury have argued that traditional set-theoretic semantics for vague languages are all but useless, however, since this mathematical precision eliminates the very phenomenon (vagueness) that we are trying to capture. Here we meet this (...) objection by viewing formalization as a process of building models, not providing descriptions. When we are constructing models, as opposed to accurate descriptions, we often include in the model extra ‘machinery’ of some sort in order to facilitate our manipulation of the model. In other words, while some parts of a model accurately represent actual aspects of the phenomenon being modelled, other parts might be merely artefacts of the particular model. With this distinction in place, the criticisms of Sainsbury and Tye are easily dealt with—the precision of the semantics is artefactual and does not represent any real precision in vague discourse. Although this solution to this problem is independent of any particular semantics a detailed account of how we would distinguish between representor and artefact within Dorothy Edgington's degree-theoretic semantics is presented.

The End of the Timeless God considers two approaches to the philosophy of time, presentism and eternalism. It is often held that God cannot be timeless if presentism is true, but can be if eternalism is true. R. T. Mullins draws on recent work in the philosophy of time as well as the work of classical Christian thinkers such as Augustine, Anselm, and Aquinas to contend that the Christian God cannot be timeless in either case.

Christian theism claims that God is in some sense responsible for the existence and nature of time. There are at least two options for understanding this claim. First, the creationist option, which says that God creates time. Second, the identification view, which says that time is to be identified with God. Both options will answer the question, “what is time?” differently. I shall consider different versions of the creationist option, and offer several objections that the view faces. I will also (...) consider different versions of the identification view, and argue that the objections it faces can be refuted. (shrink)

An introductory exploration on the nature of emotions, and examination of some of the critical issues surrounding the emotional life of God as they relate to happiness, empathy, love, and moral judgments. Covering the different criteria used in the debate between impassibility and passibility, readers can begin to think about which emotions can be predicated of God and which cannot.

In certain theological circles today, panentheism is all the rage. One of the most notorious difficulties with panentheism lies in figuring out what panentheism actually is. There have been several attempts in recent literature to demarcate panentheism from classical theism, neo-classical theism, open theism, and pantheism. I shall argue that these attempts to demarcate panentheism from these other positions fail. Then I shall offer my own demarcation.

Within contemporary evangelical theology, a peculiar controversy has been brewing over the past few decades with regard to the doctrine of the Trinity. A good number of prominent evangelical theologians and philosophers are rejecting the doctrine of divine processions within the eternal life of the Trinity. In William Hasker’s recent Metaphysics and the Tri-Personal God, Hasker laments this rejection and seeks to offer a defense of this doctrine. This paper shall seek to accomplish a few things. In section I, I (...) shall first set the stage for a proper understanding of the discussion. Section II will articulate the basic Trinitarian desiderata that must be satisfied by any model of the doctrine of the Trinity. This will help one understand the debate between Hasker and the procession deniers. Section III will offer an articulation of what the doctrine of divine processions teaches. Section IV will examine Hasker’s defense of the doctrine point by point. I shall argue that his defense of the doctrine of the divine processions fails. (shrink)

We review scholarship that examines relationships - and distinctions - between religion and delusion. We begin by outlining and endorsing the position that both involve belief. Next, we present the prevailing psychiatric view that religious beliefs are not delusional if they are culturally accepted. While this cultural exemption has controversial implications, we argue it is clinically valuable and consistent with a growing awareness of the social - as opposed to purely epistemic - function of belief formation. Finally, we review research (...) on continuities between religious and delusional cognition, which reveals that religious content is quite common in delusions and which provides tentative evidence for a positive relationship between religious belief and delusion-like belief in the general population.

The integration of biomedical terminologies is indispensable to the process of information integration. When terminologies are linked merely through the alignment of their leaf terms, however, differences in context and ontological structure are ignored. Making use of the SNAP and SPAN ontologies, we show how three reference domain ontologies can be integrated at a higher level, through what we shall call the OBR framework (for: Ontology of Biomedical Reality). OBR is designed to facilitate inference across the boundaries of domain ontologies (...) in anatomy, physiology and pathology. (shrink)

Every person acquires a worldview, a picture of reality. Within that picture, the existence of some things will be taken wholly for granted as the background to, and support of, everything else. Their existence will rarely be questioned. The cosmos or universe, the gods, God, Brahman, Heaven, the Absolute--R. T. Allen claims that all these and other world- views have been held to be that which necessarily exists and upon which all other beings depend in one way or another. European (...) philosophers, since antiquity, have offered arguments to show that their chosen candidates for the role of the necessary being or beings that support the rest of reality do actually exist. The Necessity of God sets the valid core of previous ontological arguments. It does not and cannot prove that God exists, but only that something necessarily exists. In an a priori manner and without inferring anything from what in fact exists, Allen proceeds to show that which necessarily exists is one, transfinite, eternal, and the archetype of personal existence: in short, that it is God as classically conceived. As for everything else that may exist, it must be finite and dependent for its existence upon God as its creator and sustainer. Few things are more erroneous in philosophy and disastrous in practice than artificial constructions produced without constant reference to concrete reality. That which necessarily exists may be the one exception. Before this constructive argument, Allen examines previous examples of ontological arguments in order to show exactly where they go wrong and to extract the valid core obscured within them. This will make clear the difference between them and his new version. The reader who is eager to engage the philosophical sources of belief will find a distinct treasure in The Necessity of God.

Wnts are a recently described family of secreted glycoproteins related to the Drosophila segment polarity gene, wingless, and to the proto‐oncogene, int‐1. Wnts are thought to function as developmental modulators, with signalling distances of only a few cell diameters. In Xenopus, at least six Wnts, including Xwnts‐1, ‐3A, and ‐4, are expressed initially in the developing central nervous system, with some regions expressing multiple Xwnts. Xwnt‐8 is expressed by mid‐blastula stage, in ventral and lateral mesoderm. Xwnt‐5A mRNAs are stored in (...) the egg, and later are expressed throughout the embryo in both ectoderm and mesoderm, but with a pronounced enrichment in the head and tail. Recent studies in Xenopus have pursued the diverse roles of Xwnts in early development, the mechanisms by which Xwnts signal information between cells, and the cell physiological responses to Xwnt signals.
