Some forty years on from the great events of the Second Vatican Council, there is still much debate about the interpretation of the Council and its documents. In recent years there has been what might be termed a hermeneutical project: to develop an understanding of the complex processes involved in the genesis of the texts and to explore the interactions of the various individuals and groups that helped to shape the Council. What has emerged is a view of the Council (...) as something organic and dynamic. This article seeks to outline the questions that this hermeneutical project has raised; such as the various sources that can be used to interpret the Council, the impact of various theological strands of tradition present at the Council, the authorship of the texts and the methodologies adopted by the Council. It also provides a review of the work that has taken place with this project, especially in the last ten years or so. (shrink)
Associative learning is an essential feature of human cognition, accounting for the influence of priming and interference effects on memory recall. Here, we extend our account of associative learning that learns asymmetric item-to-item associations over time via experience by including link maturation to balance associations between longer-term stability while still accounting for short-term variability. This account, combined with an existing account of activation strengthening and decay, predicts both human response times and error rates for the fan effect for both target (...) and foil stimuli.

Koonin argues that CRISPR-Cas systems present the best-known case in point for Lamarckian evolution because they satisfy his proposed criteria for the specific inheritance of acquired adaptive characteristics. We see two interrelated issues with Koonin’s characterization of CRISPR-Cas systems as Lamarckian. First, at times he appears to confuse an account of the CRISPR-Cas system with an account of the mechanism it employs. We argue there is no evidence for the CRISPR-Cas system being “Lamarckian” in any sense. Second, it is unclear (...) whether the mechanism is more “Lamarckian” than many other forms of genetic change already well-characterized in Darwinian terms. We present three conceptually distinct senses in which the mechanism of IAC may be considered Lamarckian and argue that only the strongest sense of goal-directed IAC would be difficult to accommodate in a Darwinian account. As the CRISPR-Cas mechanism does not qualify as “Lamarckian” in this strong sense, we argue there is no conceptual value in calling it “Lamarckian”. Finally, we suggest that CRISPR-Cas systems do hold the potential for genuinely non-Darwinian, directed evolution in a way that Koonin did not discuss, involving their potential use as a human gene-editing tool.

It is argued that Athenagoras, Leg. 17, draws on Pausanias 1.26.4, and may join Aelian, Pollux, Philostratus and Longus in the list of possible readers of the periegete.
Presents the basic principles of inductive logic including traditional material, such as Mill's methods, as well as more modern topics, such as statistical testing of hypotheses.
The prevailing economic paradigm, in which a closed circular flow of production and consumption can be described in terms of 'natural laws ' of the equilibrium of market forces, is being challenged by our growing knowledge of complex systems, particularly ecosystems. It is increasingly apparent that neo-classical economics does not reflect social, economic and environmental realities in a world of limited resources. The best way to understand the problems implicit in the concept of 'sustainable development ' is provided by Ecological (...) Economics – a new synthesis in which the traditional virtue of thrift is justified using modern ideas from systems theory and thermodynamics. (shrink)
In these days of inflation, perhaps we should not be surprised that the fourteenth and latest addition to the Library of Living Philosophers, should require two volumes. Previous subjects, including Bertrand Russell, Albert Einstein and G.E. Moore, were adequately accomodated within the covers of one volume. This expansion is hardly justified by the contents of the volumes. The most interesting and useful material is to be found in Popper's opening autobiographical section, but the other contributors and critics for the most (...) part are disappointing in their lack of critical bite.For this reason perhaps Popper's reply to his critics adds little to our understanding of his philosophical positions, although even when his critic is as acute as A.J. Ayer, Popper's reply has an air of defensive obfuscation.Another recent book giving a brief but clear exposition of Popper's philosophy by a former student, Bryan Magee also fails to give his views the critical examination they deserve.
