A collection of more than 40 case studies covering diverse topics such as genetic engineering, aesthetics, pollution, animal rights, population, and resource management, Case Studies in Environmental Ethics is intended as a supplemental book for college courses primarily in environmental ethics. Each case presents factual information on a particular topic, followed by a discussion of the ethical implications of each topic and several insightful discussion questions.

We develop a cultural evolutionary theory of the origins of prosocial religions and apply it to resolve two puzzles in human psychology and cultural history: (1) the rise of large-scale cooperation among strangers and, simultaneously, (2) the spread of prosocial religions in the last 10–12 millennia. We argue that these two developments were importantly linked and mutually energizing. We explain how a package of culturally evolved religious beliefs and practices characterized by increasingly potent, moralizing, supernatural agents, credible displays of faith, (...) and other psychologically active elements conducive to social solidarity promoted high fertility rates and large-scale cooperation with co-religionists, often contributing to success in intergroup competition and conflict. In turn, prosocial religious beliefs and practices spread and aggregated as these successful groups expanded, or were copied by less successful groups. This synthesis is grounded in the idea that although religious beliefs and practices originally arose as nonadaptive by-products of innate cognitive functions, particular cultural variants were then selected for their prosocial effects in a long-term, cultural evolutionary process. This framework (1) reconciles key aspects of the adaptationist and by-product approaches to the origins of religion, (2) explains a variety of empirical observations that have not received adequate attention, and (3) generates novel predictions. Converging lines of evidence drawn from diverse disciplines provide empirical support while at the same time encouraging new research directions and opening up new questions for exploration and debate.

In our response to the 27 commentaries, we refine the theoretical claims, clarify several misconceptions of our framework, and explore substantial disagreements. In doing so, we show that our framework accommodates multiple historical scenarios; debate the historical evidence, particularly about “pre-Axial” religions; offer important details about cultural evolutionary theory; clarify the termprosociality;and discuss proximal mechanisms. We review many interesting extensions, amplifications, and qualifications of our approach made by the commentators.

(1) The induced colours led to perceptual grouping and pop-out, (2) a grapheme rendered invisible through ‘crowding’ or lateral masking induced synaesthetic colours — a form of blindsight — and (3) peripherally presented graphemes did not induce colours even when they were clearly visible. Taken collectively, these and other experiments prove conclusively that synaesthesia is a genuine percep- tual phenomenon, not an effect based on memory associations from childhood or on vague metaphorical speech. We identify different subtypes of number–colour synaesthesia (...) and propose that they are caused by hyperconnectivity between col- our and number areas at different stages in processing; lower synaesthetes may have cross-wiring (or cross-activation) within the fusiform gyrus, whereas higher synaesthetes may have cross-activation in the angular gyrus. This hyperconnec- tivity might be caused by a genetic mutation that causes defective pruning of con- nections between brain maps. The mutation may further be expressed selectively (due to transcription factors) in the fusiform or angular gyri, and this may explain the existence of different forms of synaesthesia. If expressed very diffusely, there may be extensive cross-wiring between brain regions that represent abstract concepts, which would explain the link between creativity, metaphor and synaesthesia (and the higher incidence of synaesthesia among artists and poets). Also, hyperconnectivity between the sensory cortex and amygdala would explain the heightened aversion synaesthetes experience when seeing numbers printed in the ‘wrong’ colour. Lastly, kindling (induced hyperconnectivity in the temporal lobes of temporal lobe epilepsy [TLE] patients) may explain the purported higher incidence of synaesthesia in these patients. We conclude with a synaesthesia-based theory. (shrink)

Two experiments examine the effects of unreportable hints on anagram solving performance and on solvers' subjective experience of insight. In Experiment 1, after seeing a hint presented too briefly to identify, participants solved anagrams preceded by the solution fastest and solved anagrams preceded by unrelated hints slowest. Participants' “warmth” ratings for solution hints were more insight-like than those for unrelated hints. In Experiment 2 a hint, or no hint, was presented at one of three different exposure durations. Participants benefited from (...) solution-relevant hints that were either unreportable or reportable, but showed a cost only for unrelated hints that were reportable. Participants' ratings of their insight experiences showed that unreportable solution and semantically related hints produced more insight-like experiences than did unrelated hints. The results suggest that unreportable processing of solution-related information is important for the insight experience. (shrink)

Clarke and Beck suggest that the ratio processing system may be a component of the approximate number system, which they suggest represents rational numbers. We argue that available evidence is inconsistent with their account and advocate for a two-systems view. This implies that there may be many access points for numerical cognition – and that privileging the ANS may be a mistake.

We studied two otherwise normal, synaesthetic subjects who `saw' a speci¢c colour every time they saw a speci¢c number or letter. We conducted four experiments in order to show that this was a genuine perceptual experience rather than merely a memory association. (i)The synaesthetically induced colours could lead to perceptual grouping, even though the inducing numerals or letters did not. (ii)Synaesthetically induced colours were not experienced if the graphemes were presented peripherally. (iii)Roman numerals were ine¡ective: the actual number grapheme was (...) required. (iv)If two graphemes were alternated the induced colours were also seen in alternation. However, colours were no longer experienced if the graphemes were alternated at more than 4 Hz. We propose that grapheme colour synaesthesia arises from `cross-wiring' between the `colour centre' (area V4 or V8)and the `number area', both of which lie in the fusiform gyrus. We also suggest a similar explanation for the representation of metaphors in the brain: hence, the higher incidence of synaesthesia among artists and poets. (shrink)

On the basis of his acquaintance with theoretical elementary particle physics, and following the lead of Thomas Torrance, John Polkinghorne maintains that the data upon which a science is based, and the method by which it treats those data, must respect the idiosyncratic nature of the object with which the science is concerned. Polkinghorne calls this the "accommodation" (or "conformity") of a discipline to its object. The question then arises: What should we expect religious experience and theological method to be (...) like if they are accommodated to the idiosyncratic nature of God? Polkinghorne's methodological program is typical of postcritical positions in the theology-science dialogue in holding that the fiduciary element in theological method is simply a species of the fiduciary element that is a de facto part of all knowing—in other words, theological method does not differ in fundamental kind from the methods of the natural sciences. But this program may contain the seeds of an alienation of theological method from the transcendence of God similar to the double self-alienation of theology described by Michael Buckley in At the Origins of Modern Atheism. I contend that something like Bernard Lonergan's position on how the method of faith seeking understanding is related to the methods of the natural sciences is exactly the sort of thing that one should expect on the supposition of Polkinghorne's principle of accommodation, at least if the God who is the object of theological science is transcendent. The way in which the divine differs from all other objects ought to be disclosed or reflected in religious experience and theological method. Polkinghorne charts the course for an accommodated theology, but it seems to be Lonergan who is more intent on following it. (shrink)

One of the most ingenious arguments in all of Attic oratory is to be found in the speech Lysias wrote for Euphiletus to deliver at his trial for the murder of Eratosthenes . In his speech Euphiletus first describes to the court how his wife was seduced by Eratosthenes, then recounts how he discovered the affair, caught the adulterer in the act, and, despite an offer to pay compensation, slew him. Euphiletus defends his action by citing the law of the (...) Areopagus that whoever kills an adulterer caught in flagranti with his wife cannot be convicted of murder. Euphiletus further points out that the same exemption applies to the man who catches someone seducing his pallakē. If the lawgiver regarded the seduction of a pallakē as so serious that it merited the death penalty, Euphiletus argues, he must have regarded the seduction of a wife as even more reprehensible, deserving a penalty worse than death.

This article supplements our earlier paper on synaesthesia published in JCS (Ramachandran & Hubbard, 2001a). We discuss the phenomenology of synaesthesia in greater detail, raise several new questions that have emerged from recent studies, and suggest some tentative answers to these questions.

In this commentary we discuss a predictive sensorimotor illusion, the size-weight illusion, in which the smaller of two objects of equal weight is perceived as heavier. We suggest that Grush's emulation theory can explain this illusion as a mismatch between predicted and actual sensorimotor feedback, and present preliminary data suggesting that the cerebellum may be critical for implementing the emulator.

In this book Hundert proposes a new, unified view of the mind, one that integrates the insights of philosophers, psychologists, and neuroscientists. Through a detailed discussion of major theories from these and related disciplines, he gradually reveals links between what were previously unconnected approaches to human thought and experience.

Epistemology — the study of knowledge — is a philosophical discipline with close ties to psychiatry. When epistemologists address specific questions about how knowledge is actually realized by human beings, their philosophy must be informed by empirical studies of the sort psychiatrists now take up in a variety of forms. As this paper describes, psychiatrists can likewise improve their understanding of human psychology through a deeper appreciation of philosophical analysis in epistemology.The aim of this article is to introduce a unifying (...) framework within which the experience from different approaches to psychiatry — (1) the conceptual schemas of cognitive psychiatry, (2) the mental structures of psychoanalytic psychiatry, (3) the categorical forms of existential psychiatry, and (4) the neural pathways of biological psychiatry — can all be applied productively to the central question of epistemology. By establishing a broad understanding of the problem of knowledge, this new view of epistemology is developed within the idiom of each psychiatric approach. In addressing themselves to a unitary problem, these diverse psychiatric approaches are themselves revealed, not as competing points of view, but as complementary views of a single subject. The result is a new epistemology that can not only bring the insights of psychiatry to philosophy, but can also contribute to the care of patients when psychiatrists bring this broader view to their clinical work.

While corporate fiduciary duties in many jurisdictions are generally understood to be owed to shareholders, recent Canadian Supreme Court cases have held that directors owe their duties to the corporation, period, not to shareholders or any other stakeholders. This development has introduced significant indeterminacy to the law since it is not clear what such a conception of the duty requires. The Supreme Court did, however, make one clear statement: it held that directors owe a fiduciary duty to ensure that their (...) corporations obey statutory law. Such a duty encourages compliance with law, but may over-encourage compliance: individual directors do not necessarily gain personally from legal breaches, but may lose personally from them because of fiduciary liability, so they will have excessively strong incentives to avoid such breaches. The Article connects the fiduciary duty to obey law with recent developments in financial regulation that have increased the obligations on directors of financial institutions to oversee risk. By requiring directors to be engaged with risk at a governance level, regulators have enhanced the probability that directors will face liability under their fiduciary duties if their institutions do not comply with financial regulations. As the Article explains, the policy tradeoff between enhanced compliance benefits and over-compliance costs of fiduciary liability is different in the context of financial regulation from that in other settings. For example, significant corporate penalties, as opposed to penalties borne by individual directors, may be inconsistent with the prudential goals of regulation, perhaps because of toobig- to-fail concerns. The fiduciary duty to cause the corporation to obey financial regulation, and a stricter application of this duty than the highly deferential standard that exists in Delaware law, has advantages that do not exist in other legal and regulatory contexts.

At one point in his treatise against the ‘Gnostics’ Plotinus treats his adversaries as men of flesh and blood, not merely as proponents of false books and false beliefs: For I feel a certain shame with regard to some of my friends, who, having chanced upon this doctrine before the beginning of our friendship, have continued to adhere to it for reasons that I cannot understand. Not that they themselves show any compunction in saying what they say: they may believe (...) what they say to be true, but perhaps they rather wish others to be persuaded of the truth of their own opinions.

That the most poetic of all the Greek philosophers should also be the severest judge of the poets was a perpetual embarrassment to his disciples and an invitation to enemies who could never have found their way into the difficulties of his thought. At the hands of Colotes, an early Epicurean, Plato became the butt of his own asperities; the allegorist Heraclitus, showing equal contempt for Plato and for ‘the Phaeacian Epicurus’, found that philosophy lent itself to vices for which (...) the Iliad and the Odyssey had no name. Proclus, in his Commentary on the Republic, has the task of reconciling Homer with Plato, and of showing that the mythopoeic faculty is an instrument of the profoundest thought in both. (shrink)

TheClementine RecognitionsandClementine Homilies, both of which evolved between the second and the fourth centuries after Christ, are treated all too frequently as material for historians, not for critics. A book on the ancient novel is sufficiently erudite if the author shows that he has read them; theHomiliesare omitted in a volume of translations under the title ofCollected Ancient Greek Novels. It might be said that this is as it should be, since theHomiliesare largely what their title advertises, and even theRecognitionscontain (...) much that is extrinsic to the plot. By itself (it might be said) this threadbare plot holds little to engage us, and it is disposed of in a few pages in the works of Hägg and Perry. My object is to show that this neglect is undeserved.

I attempt to clarify the connection between two late texts by V.S. Solov''ëv: Justification of the Good and Theoretical Philosophy. Solov''ëv drew attention to the intrinsic connection between moral and intellectual virtues. Theoretical Philosophy is the initial -- unfinished -- sketch of the dynamism of mind seeking truth as a good. I sketch several parallels and analogies between the doctrine of moral experience set out in Justification and the account of the intellect''s dynamism based on immediate certitude set out in (...)

I conclude by suggesting that Solov''ëv''s position on these questions does not easily cohere with the impersonalism he appears to defend in Theoretical Philosophy. (shrink)

This study explores the nature of parental attitudinal beliefs towards educational inclusion and the factors that determine these beliefs. Participants were drawn from the Growing Up in Scotland Survey. Results indicate that majority of parents held positive generalised belief towards including children with additional support needs in mainstream classrooms, compared with belief about the benefits of inclusion for children with ASN, or benefits for typically developing children. Lower parental income and higher levels of satisfaction with child’s current school were associated (...) with positive generalised beliefs. Belief about the benefits of inclusion for children with ASN was also positively associated with lower parental income, while belief about benefits for typically developing children was determined by higher parental education and age. Our findings suggest that efforts to increase parental attitudes should target salient beliefs and take into account the determinants of each of these beliefs. (shrink)

Associations between family income and child developmental outcomes are well documented. However, family income is not static but changes over time. Although this volatility represents income shocks that are likely to affect children’s lives, very few studies have so far examined its effect on early cognitive development. This study investigated associations between family income, volatility, and changes in cognitive outcomes in early childhood and examined whether these associations are dependent on a family’s overall income position. Data for the study spanned (...) five waves of the Growing Up in Scotland longitudinal survey. Findings indicate that income volatility was more prevalent among disadvantaged sociodemographic groups. In addition to average income, short-term volatility was associated with changes in child cognitive outcomes from ages 3 to 5. While upward volatility was associated with gains in expressive vocabulary, downward and fluctuating volatility were associated with declines in child problem-solving abilities. The association between volatility and changes in cognitive outcomes was similar for both children living in poverty and those from medium–high-income households. Our results suggest that policies aiming to cushion all families from negative income shocks, boost family income to ensure stability, and take low-income families out of poverty will have a significant impact on children’s cognitive development. Additionally, a more nuanced conceptualization of income is needed to understand its multidimensional impact on developmental outcomes. (shrink)
