This thesis presents and criticizes Hilary Putnam's argument that mathematics is as empirical as science, in particular the argument that the switch from Euclidean geometry to Riemannian geometry as the approporiate geometry for physical space constituted an instance of revising mathematics as a result of observation. The thesis explains Putnam's views on mathematics as following from his theory of meaning and reference for natural kind terms. It is argued that Putnam's account of reference is unsuitable for mathematical terms and that (...) an "if-thenist" approach to mathematical knowledge is more fruitful. (shrink)

Flora Levin explores how and why music was so important to the ancient Greeks. She examines the distinctions that they drew between the theory of music as an art ruled by number and the theory wherein number is held to be ruled by the art of music. These perspectives generated more expansive theories, particularly the idea that the cosmos is a mirror-image of music's structural elements and, conversely, that music by virtue of its cosmic elements - time, motion, and the (...) continuum - is itself a mirror-image of the cosmos. These opposing perspectives gave rise to two opposing schools of thought, the Pythagorean and the Aristoxenian. Levin argues that the clash between these two schools could never be reconciled. Her book shows how the Greeks' appreciation of the profundity of music's interconnections with philosophy, mathematics, and logic led to groundbreaking intellectual achievements that no civilisation has ever matched.

Advanced Cell Technology's Ethics Advisory Board has been called window dressing for a corporate marketing plan. But the scientists and managers have paid attention, and the lawyers have gone along.

In this book, 11 leading scholars contribute to the understanding of the scientific and philosophical works of Moses Maimonides (1135-1204), the most luminous Jewish intellectual since Talmudic times. Deeply learned in mathematics, astronomy, astrology (which he strongly rejected), logic, philosophy, psychology, linguistics, and jurisprudence, and himself a practising physician, Maimonides flourished within the high Arabic culture of the 12th century, where he had momentous influence upon subsequent Jewish beliefs and behavior, upon ethical demands, and upon ritual traditions. For him, mastery (...) of the sciences was indispensable in the process of religious fulfilment. (shrink)

We use Homer and Sun Tzu as a background to better understand and reformulate confrontation, anger and violence in medicine, contrasting an unproductive ‘love of war’ with a productive ‘art of war’ or ‘art of strategy’. At first glance, it is a paradox that the healing art is not pacific, but riddled with militaristic language and practices. On closer inspection, we find good reasons for this cultural paradox yet regret its presence. Drawing on insights from Homer's The Iliad and The (...) Odyssey, we argue for better understanding of confrontation, anger, bullying, intimidation and violence in medicine in order to change the culture. For example, equating medicine with war is not a given condition of medicine but a convenient metaphor with historical origins and a historical trajectory. Other, non-martial metaphors, such as medicine as collaboration, may be more appropriate in an age of team-based care. Taking lessons from Homer, we suggest three key ways in which cold-hearted confrontation and anger in medicine can be transformed into productive, warm-hearted engagement: the transformation of angry impulse into reflection, moral courage and empathy. Thinking with Homer can offer an aesthetically and morally charged alternative to the current body of literature on topics, such as anger in doctors, and how this may be ‘managed’, without recourse to an instrumental economy where emotions are viewed as commodities, and emotional responses can be ‘trained’ through communication skills courses.

Observers have difficulty detecting visual changes. However, they are unaware of this inability, suggesting that people do not have an accurate understanding of visual processes. We explored whether this error is related to participants’ beliefs about the roles of intention and scene complexity in detecting changes. In Experiment 1 participants had a higher failure rate for detecting changes in an incidental change detection task than an intentional change detection task. This effect of intention was greatest for complex scenes. However, participants (...) predicted equal levels of change detection for both types of changes across scene complexity. In Experiment 2, emphasizing the differences between intentional and incidental tasks allowed participants to make predictions that were less inaccurate. In Experiment 3, using more sensitive measures and accounting for individual differences did not further improve predictions. These findings suggest that adults do not fully understand the role of intention and scene complexity in change detection. (shrink)

Ayahuasca, a hallucinogen with profound consciousness- altering properties, has been increasingly utilized in recent studies (e.g., Strassman, 2001; Shanon, 2002a,b). However, other than Shanon's recent work, there has been little attempt to examine the effects of ayahuasca on perceptual, affective and cognitive experience, its relation to fringe consciousness or to pertinent personality variables. Twenty-one volunteers attending a seminar on ayahuasca were administered personality measures and a semi-structured interview about phenomenal qualities of their experience. Ayahuasca ingestion was associated with profound alterations (...) of temporal- spatial experiences including expansive space and slowed time. Ayahuasca use was also associated with positive emotional states, higher levels of fantasy proneness and psychological absorption and a greater openness to mystical experiences. Conversely, quickened time was associated with negative emotionality. The results are discussed within a multi-faceted model of fringe consciousness with a particular emphasis on Hunt's (1995) models of cross-modal translation as the basis for higher-order symbolic cognition and support James' (1890/1950) contention that fringe consciousness is essential to human cognition.

Smilek, Eastwood, Reynolds, and Kingstone suggests that the studies reported in Beck, M. R., Levin, D. T. and Angelone, B. A. are not ecologically valid. Here, we argue that not only are change blindness and change blindness blindness studies in general ecologically valid, but that the studies we reported in Beck, Levin, and Angelone, 2007 are as well. Specifically, we suggest that many of the changes used in our study could reasonably be expected to occur in the real world. Furthermore, (...) the conclusion from Beck et al. that knowledge about the role of intention and scene complexity in change detection is not readily accessible applies not only to the laboratory studies we conducted but also to real world situations.

This article argues that we could improve the design of research protocols by developing an awareness of and a responsiveness to the social contexts of all the actors in the research enterprise, including subjects, investigators, sponsors, and members of the community in which the research will be conducted. ?Social context? refers to the settings in which the actors are situated, including, but not limited to, their social, economic, political, cultural, and technological features. The utility of thinking about social contexts is (...) introduced and exemplified by the presentation of a hypothetical case in which one central issue is limitation of the probability of injury to subjects by selection of individuals who are not expected to live long enough for the known risks of the study to become manifest as harms. Benefits of such considerations may include enhanced subject satisfaction and cooperation, community acceptance, and improved data quality, among other desirable consequences. (shrink)

Recently, a number of experiments have emphasized the degree to which subjects fail to detect large changes in visual scenes. This finding, referred to as “change blindness,” is often considered surprising because many people have the intuition that such changes should be easy to detect. Levin, Momen, Drivdahl, and Simons documented this intuition by showing that the majority of subjects believe they would notice changes that are actually very rarely detected. Thus subjects exhibit a metacognitive error we refer to as (...) “change blindness blindness.” Here, we test whether CBB is caused by a misestimation of the perceptual experience associated with visual changes and show that it persists even when the pre- and postchange views are separated by long delays. In addition, subjects overestimate their change detection ability both when the relevant changes are illustrated by still pictures, and when they are illustrated using videos showing the changes occurring in real time. We conclude that CBB is a robust phenomenon that cannot be accounted for by failure to understand the specific perceptual experience associated with a change. (shrink)

Amidst the “lavender scare” of the Cold War, James Schuyler, “the great queer voice of the New York School,” subverted the state’s auditory surveillance of queer life. Refunctionalizing its tools of espionage as poetic tactics, Schuyler eavesdrops on errant conversations (the espoused) and joining (espousing) them in paratactic assembly. In so doing, Schuyler expands José Esteban Muñoz’s “queer optic,” the utopian capacity to see beauty amidst ruins, beyond the visual into a queer otic that drags into being a world of (...) freer espousal. I survey the aural surveillance of mid-century queer life before tracing Schuyler’s détournement of bugging, wiretapping, and overhearing in his 1969 Freely Espousing. In turn, I uncover the queer political commitments lurking beneath Schuyler’s classification as a pastoral lyricist concerned only with “leaves and flowers and weather.”. (shrink)

Previous research demonstrates that implicitly learned probability information can guide visual attention. We examined whether the probability of an object changing can be implicitly learned and then used to improve change detection performance. In a series of six experiments, participants completed 120–130 training change detection trials. In four of the experiments the object that changed color was the same shape on every trial. Participants were not explicitly aware of this change probability manipulation and change detection performance was not improved for (...) the trained shape versus untrained shapes. In two of the experiments, the object that changed color was always in the same general location . Although participants were not explicitly aware of the change probability, implicit knowledge of it did improve change detection performance in the trained location. These results indicate that improved change detection performance through implicitly learned change probability occurs for location but not shape. (shrink)
