Context. The identification of the sources that reionized the Universe and their specific contribution to this process are key missing pieces of our knowledge of the early Universe. Faint star-forming galaxies may be the main contributors to the ionizing photon budget during the epoch of reionization, but their escaping photons cannot be detected directly due to inter-galactic medium opacity. Hence, it is essential to characterize the properties of faint galaxies with significant Lyman continuum photon leakage up to z 4 to (...) define indirect indicators allowing analogues to be found at the highest redshift. Aims. Long gamma-ray bursts explode typically in star-forming regions of faint, star-forming galaxies. Through LGRB afterglow spectroscopy it is possible to detect directly LyC photons. Our aim is to use LGRBs as tools to study LyC leakage from faint, star-forming galaxies at high redshift. Methods. Here we present the observations of LyC emission in the afterglow spectra of GRB 191004B at z = 3:5055, together with those of the other two previously known LyC-emitting LGRB, to determine their LyC escape fraction and compare their properties. Results. From the afterglow spectrum of GRB 191004B we determine a neutral hydrogen column density at the LGRB redshift of og =17:2 0:15, and negligible extinction. The only metal absorption lines detected are C iv and Si iv. In contrast to GRB 050908 and GRB 060607A, the host galaxy of GRB 191004B displays significant Ly emission. From its Ly emission and the non-detection of Balmer emission lines we constrain its star-formation rate to 1 SFR 4:7 M yr. 1. We fit the Ly emission with a shell model and find parameters values consistent with the observed ones. The absolute LyC escape fractions we find for GRB 191004B, GRB 050908 and GRB 060607A are of 0:35+0:10.0:11, 0:08+0:05.0:04 and :20+0:05.0:05, respectively. We compare the LyC escape fraction of LGRBs to the values of other LyC emitters found from the literature, showing that LGRB afterglows can be powerful tools to study LyC escape for faint high-redshift star-forming galaxies. Indeed we could push LyC leakage studies to much higher absolute magnitudes. The host galaxies of the three LGRB presented here have all M1600 >.19:5 mag, with the GRB 060607A host at M1600 >.16 mag. LGRB hosts may therefore be particularly suitable for exploring the ionizing escape fraction in galaxies that are too faint or distant for conventional techniques. Furthermore the time investment is very small compared to galaxy studies. (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.

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.

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.

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.

Professor Flew has recently sought to demolish the philosophical pretensions of Marx and the Marxists by the use of Hume's Fork and Popper's demand for falsifiable consequences. Marx tried to derive matters of ‘fact and existence’ from ‘relations of ideas’, which Hume's Fork states to be impossible. From this and not from empirical study, he derived predictions for the future course of history which neither he nor his followers have ever properly tested by empirical enquiries. Nor have they ever provided (...) any clear, unambiguous and therefore testable formulations of those predictions. In particular, Flew claims, they have never given any concrete content to the central notion of ‘alienation’ such that an Index of Alienation could be drawn up and enquiries could be made as to whether, for example, the workers are more or less alienated under the private or public ownership of factories. Both faults stem from Marx's continuation of German, specifically Hegelian, philosophy. (shrink)

We first consider the entailment logic MC, based on meaning containment, which contains neither the Law of Excluded Middle (LEM) nor the Disjunctive Syllogism (DS). We then argue that the DS may be assumed at least on a similar basis as the assumption of the LEM, which is then justified over a finite domain or for a recursive property over an infinite domain. In the latter case, use is made of Mathematical Induction. We then show that an instance of the (...) LEM is intrumental in the proof of Cantor's Theorem, and we then argue that this is based on a more general form than can be reasonably justified. We briefly consider the impact of our approach on arithmetic and naive set theory, and compare it with intuitionist mathematics and briefly with recursive mathematics. Our "Four Basic Logical Issues" paper would provide useful background, the current paper being an application of the some of the ideas in it. (shrink)

This article tries to analyze the meaning of a decent minimum of health care, by confronting the idea of decent care with the concept of justice. Following the ideas of Margalith about a decent society, the article argues that a just minimum of care is not necessarily a decent minimum. The way this minimum is provided can still humiliate individuals, even if the end result is the best possible distribution of the goods as seen from the viewpoint of justice. This (...) analysis is combined with an analysis from the perspective of solidarity, particularly of reflective solidarity, as a way to develop decent care, which is care that does not humiliate individuals and maintains their dignity.

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.

This edited volume of original contributions deals with the economic and political thought of Michael Polanyi. Requiring little prior knowledge of Polanyi, this volume further develops a somewhat neglected side of Polanyi's work. In particular it examines the 'tacit integration', of subsidiary details into focal objects or actions as central to all knowing and action. It traces ontological counterparts in the structures of comprehensive entities and complex actions, and a multi-level universe in which lower levels have their boundary conditions, the (...) extents to which they apply, determined by those of the next higher level, whilst each possessing its own laws or operative principles. This schema of 'dual control' preserves the reality and relative autonomy of each level, and its interactions with others, against the various reductions. The essays in this volume also employ and develop important additional concepts and distinctions such as: 'corporate' and 'spontaneous' order; 'public' and 'private' liberties; 'general' and 'specific authority'; and 'moral inversion'; which, as the essays show, are necessary for understanding and maintaining a free society and the freedom of institutions within it. Among the topics treated with them are: more of the prerequisites of freedom in public liberties dedicated to principles and transcendent values; totalitarianism and society as spontaneous order; the balance of general and specific authority in society and particular institutions; reductionism, totalitarianism and consumption in consumer societies, as moral inversions; the mutual interactions of economics and politics as distinct and autonomous but interacting levels; the sociological aspects of economics; and Polanyi's own contributions to sociology. Although, as indicated, Polanyi has his special terms, the essays in this volume, like his works, give them meaning with concrete examples and so avoid merely shuffling a mass of abstractions. Together the essays show that his work is a rich seam of ideas and inspiration for yet further extension and application--Publisher. (shrink)

In a recent paper on panentheism, Raphael Lataster and Purushottama Bilimoria offer a critique of several contemporary attempts to define what panentheism is and what panentheism is not. Lataster and Bilimoria find the recent attempts to define panentheism deficient. In particular, they find my approach to panentheism to be riddled with problems. In my reply, I explain that Lataster and Bilimoria have failed to explain what panentheism is and what it is not.

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.

The philosophical problem of knowledge of other minds is rational justifiction. this paper covers n malcolm, h h price, j mill, strawson, hamshire, l wittgenstein and a j ayer's controversial thought. philosophical scepticism holds that it is logically impossible to know mental experiences. "i know, i have a pain." how do i know that other people also can have similar pain? it provides as ideal knowledge of mental events. when i say, "i have a pain," i can have certain knowledge (...) of this because i have conclusive individual evidence for it.
