The main aim of this paper is to demonstrate the viability and fruitfulness of employing a cybernetic formulation for analyzing many important facets of goal-directed activity, both non-purposeful and purposeful. Unsuccessful past attempts at this program are examined. A reformulation of the cybernetic analysis is proposed which avoids the pitfalls of these attempts by constructing evidentiary tests for rather than a behavioral definition of goal-directedness. This new formulation enables one to counter the most salient criticisms of a cybernetic analysis. A cybernetic account of goal-directedness retains the distinguishing features of teleological explanations without construing them as distinct in kind from causal ones. An empirically adequate sense of the causal efficacy of goals is proposed.

© 2015 Elsevier Ireland Ltd.The fornix is the primary subcortical output fiber system of the hippocampal formation. In children with 22q11.2 deletion syndrome, hippocampal volume reduction has been commonly reported, but few studies as yet have evaluated the integrity of the fornix. Therefore, we investigated the fornix of 45 school-aged children with 22q11.2DS and 38 matched typically developing children. Probabilistic diffusion tensor imaging tractography was used to reconstruct the body of the fornix in each child[U+05F3]s brain native space. Compared with children, significantly lower fractional anisotropy and higher radial diffusivity was observed bilaterally in the body of the fornix in children with 22q11.2DS. Irregularities were especially prominent in the posterior aspect of the fornix where it emerges from the hippocampus. Smaller volumes of the hippocampal formations were also found in the 22q11.2DS group. The reduced hippocampal volumes were correlated with lower fornix FA and higher fornix RD in the right hemisphere. Our findings provide neuroanatomical evidence of disrupted hippocampal connectivity in children with 22q11.2DS, which may help to further understand the biological basis of spatial impairments, affective regulation, and other factors related to the ultra-high risk for schizophrenia in this population.

In this truly interdisciplinary study that reflects the author's work in philosophy, political science, law, and policy studies, Thomas W. Simon argues that democratic theory must address the social injustices inflicted upon disadvantaged groups. By shifting theoretical sights from justice to injustice, Simon recasts the nature of democracy and provides a new perspective on social problems. He examines the causes and effects of injustice, victims' responses to injustice, and historical theories of disadvantage, revealing that those theories have important repercussions for contemporary policy debates. Finally, Simon considers which institutions and practices come within the grasp of democracy and discusses the concept of a 'Negative Utopia,' or a future without injustice

A hierarchical ordering of approaches afflicts environmental thinking. An ethics of individualism unjustly overrides social/political philosophy in environmental debates. Dialectics helps correct this imbalance. In dialectical fashion, a synthesis emerges between conflicting approaches to dialectics and to nature from: Marxism (Levins and Lewontin), anarchism (Bookchin), and Native Americanism (Black Elk). Conflicting (according to Marxists) and cooperative (according to anarchists) forces both operate in nature. Ethics (anarchist), political theory (Marxist), and spirituality (Native American) constitute the interconnected interpretative domains of a dialectically informed ecophilosophy. In a world painted too often in blacks and whites, ecological dialectics colors the picture a more realistic gray.

Some might say that there is a sense in which the very consideration of whether science is equated with rationality is obscene. For far too long science has been dealt with by philosophers within the confines of a protectionist, if not an apologist, policy. Putnam has provided a service by exposing some of the weaker links of the scientism mythology. I have tried to bolster that critique by indicating how, along Bayesian lines, value and holistic considerations could be used to help positively transform science.Richard Rudner would have undoubtedly agreed with very little of what I have said — he seldon did. But he would have been there with open-mind and open-heart. Forqua mentor andqua friend he was, indeed, the philosopher par excellence
