This project tested a two-way model of communication between lay groups and experts about genetic medicine in Perth, Western Australia. Focus group discussion with community group participants was followed by a communication workshop between community group participants and experts. Four groups of concerns or themes emerged from discussion: clinical considerations; legislative concerns; research priorities, and ethical and wider considerations. Community group concerns are not always met by the actions of "experts". This is, in part, because of the differing life-worlds of (...) each group. However, the communication workshop showed the potential of two-way communication for both lay and expert members in understanding the others' viewpoint. Further, the approach developed here offers one possible way for community groups to participate in a substantial way in policy formulation processes. (shrink)

We discuss five kinds of representations of rationales and provide a formal account of how they can alter disputation. The formal model of disputation is derived from recent work in argument. The five kinds of rationales are compilation rationales, which can be represented without assuming domain-knowledge (such as utilities) beyond that normally required for argument. The principal thesis is that such rationales can be analyzed in a framework of argument not too different from what AI already has. The result is (...) a formal understanding of rationales, a partial taxonomy, and a foundation for computer programs that represent and reason with rationales.The five kinds of rationales are as follows: (c)ompression and (s)pecialization, which yield rules, and (d)isputation, which yields a decision. These are modeled as potentially changing the focus of the dispute. Then there are (f)it, a rationale for rules, and (r)esolution, a rationale for decisions. These cannot be modeled as simply; they force disputation to a meta-level, at least temporarily. (shrink)

I answer Alvin Plantinga's challenge to provide a ‘proper’ de jure objection to religious belief. What I call the ‘sophisticates’ evidential objection' concludes that sophisticated Christians lack epistemic justification for believing central Christian propositions. The SEO utilizes a theory of epistemic justification in the spirit of the evidentialism of Richard Feldman and Earl Conee. I defend philosophical interest in the SEO against objections from Reformed epistemology, by addressing Plantinga's criteria for a proper de jure objection, his anti-evidentialist arguments, and the (...) relevance of ‘impulsional evidence’. I argue that no result from Plantinga-style Reformed epistemology precludes the reasons I offer in favour of giving the SEO its due philosophical attention. (shrink)

Rationalizing the perceptual effects of spectral stimuli has been a major challenge in vision science for at least the last 200 years. Here we review evidence that this otherwise puzzling body of phenomenology is generated by an empirical strategy of perception in which the color an observer sees is entirely determined by the probability distribution of the possible sources of the stimulus. The rationale for this strategy in color vision, as in other visual perceptual domains, is the inherent ambiguity of (...) the real-world origins of any spectral stimulus. (shrink)

On the heels of the advance since the twentieth-century of wholly physicalist accounts of human persons, the influence of materialist ontology is increasingly evident in Christian theologizing. To date, the contemporary literature has tended to focus on anthropological issues (e.g., whether the traditional soul / body distinction is viable), with occasional articles treating physicalist accounts of such doctrines as the Incarnation and Resurrection of Jesus cropping up, as well. Interestingly, the literature to date, both for and against this influence, is (...) dominated by philosophers. The present volume is a collection of philosophers and theologians who advance several novel criticisms of this growing trend toward physicalism in Christian theology. The present collection definitively shows that Christian physicalism has some significant philosophical and theological problems. No doubt all philosophical anthropologies have their challenges, but the present volume shows that Christian physicalism is most likely not an adequate accounting for essential theological topics within Christian theism. Christians, then, should consider alternative anthropologies. (shrink)

In The Colorful Conservative, R.O.P. Lopez culls important insights into American culture from the works of Phillis Wheatley, Edgar Allan Poe, Henry David Thoreau, William Wells Brown, and Walt Whitman. Lopez contends that many of the tensions that emerged prior to the Civil War remain unresolved; thus, the nineteenth century never ended and Americans still live in the literary framework of the 1800s. Beyond political distinctions of the left and the right, there are really four poles: The Left, The Conformist (...) Burkeans, The Anarchist-Nihilist-Libertarians, and The Colorful Conservatives. The Left and the Colorful Conservatives are the two poles most at odds with each other. The Colorful Conservatives, Lopez argues, encompass these five American authors and are the driving force behind many unique paradoxes in the United States' political culture"--Back cover. (shrink)
