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.

We are not convinced by Gangestad & Simpson that differential mating strategies within each sex would be greater than such strategies between sexes. The target article does not provide actual evidence of human males who do not desire mating with multiple females, or evidence that the benefits for females of short-term matings with multiple males have ever outweighed the associated costs.

Quartz & Sejnowski (Q&S) disregard evidence that suggests that their view of dendrites is inadequate and they ignore recent results concerning the role of neurotrophic factors in synaptic remodelling. They misrepresent neuronal selectionism and thus erect a straw-man argument. Finally, the results discussed in section 4.2 require neuronal proliferation, but this does not occur during the period of neuronal development of relevance here.

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.

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.

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.

According to classical theism, impassibility is said to be systematically connected to divine attributes like timelessness, immutability, simplicity, aseity, and self-sufficiency. In some interesting way, these attributes are meant to explain why the impassible God cannot suffer. I shall argue that these attributes do not explain why the impassible God cannot suffer. In order to understand why the impassible God cannot suffer, one must examine the emotional life of the impassible God. I shall argue that the necessarily happy emotional life (...) of the classical God explains why the impassible God cannot suffer. (shrink)

In a previous publication, I offered a novel argument against physicalist approaches to the Incarnation called “the Two Sons Worry.” In brief, I argued that a physicalist who is committed to the ecumenical teachings about the Incarnation cannot easily escape the worry that there are two persons in Jesus Christ. Keith Hess has recently pointed out a flaw in the argument that I present. In this paper, I offer a reply that fixes the argument, thus leaving the problem for the (...) physicalist intact.

This new study of modern educational thought relates the selected thinkers and theories to a profound change in the way in which men have come to understand themselves and the world. The theories of Rousseau, Kant, Froebel, Hegel, Marx, Nietzsche contemporary English-speaking philosophers and schemes of education, Sartre, Helvetius and B.F. Skinner, are shown, in separate studies, to be variations upon the theme of man as a self-defining and self-legislating subject in a world that does nothing to present him with (...) any Law or Way. Education therefore becomes a problem, a matter of arbitrary selection of what the young are to be taught and to do. (shrink)

Allen examines Polanyi's and Hayek's thinking with respect to the nature, value, and foundations of liberty. For Allen, only Christianity, and certainly no modern philosophy, has a conception of the unique individual and his irreplaceable value and of a political order that transcends itself into the moral order. Beyond Liberalism challenges deeply ingrained notions of liberty and its meaning in modern society.
