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)

This article examines the development of Russell's treatment of propositions, in relation to the topic of psychologism. In the first section, we outline the concept of psychologism, and show how it can arise in relation to theories of the nature of propositions. Following this, we note the anti-psychologistic elements of Russell's thought dating back to his idealist roots. From there, we sketch the development of Russell's theory of the proposition through a number of its key transitions. We show that Russell, (...) in responding to a variety of different problems relating to the proposition, chose to resolve these problems in ways that continually made concessions to psychologism.

(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)

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)

Porphyry'sLife of Plotinusis the earliest extant memoir of a philosopher by his pupil. Historians of philosophy have embraced it as a key to the intellectual development of Plotinus, while historians of the third century have found it an invaluable supplement to the fragmentary records of this era. Yet few have cared to read it as an original work of literature, or even as the mature work of a scholar and philosopher who for centuries eclipsed his master in influence, if not (...) in reputation. In consequence, attention has not been paid to certain striking peculiarities in Porphyry's selection and arrangement of materials, which, if studied, will shed light on the form and purpose of the whole biography. This article is devoted to a strange chapter which, as in any ancient writing, we should expect to be the most instructive because it is the first. (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.

As Edward Hundert--a philosopher, psychiatrist, and award-winning educator--makes clear in this eloquent interdisciplinary work, the newly emerging model for ...

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.

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 (...) Theoretical Philosophy. Solov''ëv can thus be considered as a virtue epistemologist in the current meaning given to this description. 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)
