The purpose of this article is to introduce, interpret, and develop two incompatible process -ontological theories of personal identity that have received little attention in analytic metaphysics. The first theory derives from the notion of personal identity proposed in Alfred North Whitehead’s philosophy, but I interpret this notion differently from previous commentators. The Whiteheadian theory may appeal to those who believe that personal identity involves an entity or entities that are essentially dynamic, but has nothing to do with diachronic objectual (...) identity : the binary equivalence relation that every entity bears to itself, and only to itself, even after undergoing intrinsic change. The Whiteheadian theory may also find favor with those who, like Whitehead, reject the possibility of pure processes and hold that in every becoming, something—which need not be an object, thing, or individual substance—becomes. The second theory derives from the notion of recurrent dynamics presented in Johanna Seibt’s General Process Theory. The Seibtian theory may appeal to those who believe that personal identity involves not only an entity or entities that are essentially dynamic, but also the relation of diachronic objectual identity. The Seibtian theory may also find favor with those who, like Broad and Sellars, find reason to postulate pure processes. (shrink)

The Study of Time XVI: Time's Urgency celebrates the 50th anniversary of the International Society for the Study of Time. It includes a keynote speech by renowned physicist Julian Barbour, a dialogue between British author David Mitchell, Katie Paterson and ISST's previous president Paul Harris. The volume is divided into dialogues and papers that directly address the issue of urgency and time scales from various disciplines. This book offers a unique perspective on the contemporary status of the interdisciplinary study of (...) time. It will open new paths of inquiry for different approaches to the important issues of narrative structure and urgency. These are themes that are becoming increasingly relevant during our times.

Processing of emotional speech in the absence of visual information relies on two auditory channels: semantics and prosody. No study to date has investigated how blindness impacts this process. Two theories, Perceptual Deficit, and Sensory Compensation, yiled different expectations about the role of visual experience (or its lack thereof) in processing emotional speech. To test the effect of vision and early visual experience on processing of emotional speech, we compared individuals with congenital blindness (CB, n = 17), individuals with late (...) blindness (LB, n = 15), and sighted controls (SC, n = 21) on identification and selective-attention of semantic and prosodic spoken-emotions. Results showed that individuals with blindness performed at least as well as SC, supporting Sensory Compensation and the role of cortical reorganisation. Individuals with LB outperformed individuals with CB, in accordance with Perceptual Deficit, supporting the role of early visual experience. The LB advantage was moderated by executive functions (working-memory). Namely, the advantage was erased for individuals with CB who showed higher levels of executive functions. Results suggest that vision is not necessary for processing of emotional speech, but early visual experience could improve it. The findings support a combination of the two aforementioned theories and reject a dichotomous view of deficiencies/enhancements of blindness. (shrink)

The loss or absence of vision is probably one of the most incapacitating events that can befall a human being. The importance of vision for humans is also reflected in brain anatomy as approximately one third of the human brain is devoted to vision. It is therefore unsurprising that throughout history many attempts have been undertaken to develop devices aiming at substituting for a missing visual capacity. In this review, we present two concepts that have been prevalent over the last (...) two decades. The first concept is sensory substitution, which refers to the use of another sensory modality to perform a task that is normally primarily sub-served by the lost sense. The second concept is cross-modal plasticity, which occurs when loss of input in one sensory modality leads to reorganization in brain representation of other sensory modalities. Both phenomena are training-dependent. We also briefly describe the history of blindness from ancient times to modernity, and then proceed to address themeansthat have been used to help blind individuals, with an emphasis on modern technologies, invasive (various type of surgical implants) and non-invasive devices. With the advent of brain imaging, it has become possible to peer into the neural substrates of sensory substitution and highlight the magnitude of the plastic processes that lead to a rewired brain. Finally, we will address the important question of the value and practicality of the available technologies and future directions. (shrink)

Scientific advancement is inextricably linked to cultural advancement, and historically the arts have worked hand in hand with technological change. This essay explores some of the connections that exist between science, technology, and the arts, privileging instances where technological change resulted in new forms of artistic creation. Although the role of the arts in contemporary society has ebbed in comparison to that of technology and science, the essay argues that quality, meaningfulness, and longevity are key components in how the arts (...) can retain cultural value in today’s technocentric world. It explores significant instances from the history of music and visual art as the authors make the case that the methods of science and art are both distinct yet commensurate in their ability to shape the values and ideas of contemporary society.

Four predictors were posited to affect business student attitudes about the social responsibilities of business, also known as corporate social responsibility (CSR). Applying Forsyth's (1980, "Journal of Personality and Social Psychology" 39, 175–184, 1992, "Journal of Business Ethics" 11, 461–470) personal moral philosophy model, we found that ethical idealism had a positive relationship with CSR attitudes, and ethical relativism a negative relationship. We also found materialism to be negatively related to CSR attitudes. Spirituality among business students did not significantly predict (...) CSR attitudes. Understanding the relationship between CSR attitudes and the significant predictors has important implications for researchers and teachers in particular. (shrink)

Majority cycling and related social choice paradoxes are often thought to threaten the meaningfulness of democracy. But deliberation can prevent majority cycles – not by inducing unanimity, which is unrealistic, but by bringing preferences closer to single-peakedness. We present the first empirical test of this hypothesis, using data from Deliberative Polls. Comparing preferences before and after deliberation, we find increases in proximity to single-peakedness. The increases are greater for lower versus higher salience issues and for individuals who seem to have (...) deliberated more versus less effectively. They are not merely a byproduct of increased substantive agreement. Our results both refine and support the idea that deliberation, by increasing proximity to single-peakedness, provides an escape from the problem of majority cycling. (shrink)

The current study examined whether pigeons could learn to use abstract concepts as the basis for conditionally switching behavior as a function of time. Using a mid-session reversal task, experienced pigeons were trained to switch from matching-to-sample (MTS) to non-matching-to-sample (NMTS) conditional discriminations within a session. One group had prior training with MTS, while the other had prior training with NMTS. Over training, stimulus set size was progressively doubled from 3 to 6 to 12 stimuli to promote abstract concept development. (...) Prior experience had an effect on the initial learning at each of the set sizes but by the end of training there were no group differences, as both groups showed similar within-session linear matching functions. After acquiring the 12-item set, abstract-concept learning was tested by placing novel stimuli at the beginning and end of a test session. Prior matching and non-matching experience affected transfer behavior. The matching experienced group transferred to novel stimuli in both the matching and non-matching portion of the sessions using a matching rule. The non-matching experienced group transferred to novel stimuli in both portions of the session using a non-matching rule. The representations used as the basis for mid-session reversal of the conditional discrimination behaviors and subsequent transfer behavior appears to have different temporal sources. The implications for the flexibility and organization of complex behaviors are considered. (shrink)

Barrett et al. present four puzzles for the ZFEL-view of evolution that we present in our 2010 book, Biology’s First Law: The Tendency for Diversity and Complexity to Increase in Evolutionary Systems. Our intent in writing this book was to present a radically different way to think about evolution. To the extent that it really is radical, it will be easy to misunderstand. We think Barrett et al. have misunderstood several crucial points and so we welcome the opportunity to clarify.

Bruineberg et al. provide compelling clarity on the roles Markov blankets could (and perhaps should) play in the study of life and mind. However, here we draw attention to a further role blankets might play: as a hypothesis about cognition itself. People and other animals may use blanket-like representations to model the boundary between themselves and their worlds.

Boddy and his colleagues have published several articles on “corporate psychopathy” using what they refer to as a Psychopathy Measure—Management Research Version. They based this measure on the items that comprise the Interpersonal and Affective dimensions of the Hare Psychopathy Checklist-Revised, a widely used copyrighted and controlled instrument. The PM-MRV not only misspecifies the construct of psychopathy, but also serves as an example of the problems associated with an attempt to form a “new” scale by adapting items from a proprietary (...) scale. The PCL-R measures a superordinate construct underpinned by four correlated dimensions or first-order factors, not just the two in the PM-MRV. The other two dimensions are Lifestyle and Antisocial, which together form Factor 2 of the PCL-R. As defined by the PCL-R, psychopathy requires high scores on both Factor 1 and Factor 2. Lack of validity aside, even if the PM-MRV were to be a useful measure of Factor 1, it would not discriminate between psychopathy and other “dark personalities,” such as Machiavellianism and narcissism, which, along with psychopathy, form the Dark Triad. This lack of discrimination stems from the fact that each of these personalities shares features measured by Factor 1 and, by implication, by the PM-MRV. Research findings based on the PM-MRV may have some meaning with respect to dark personalities in general, but their relevance to psychopathy, as measured with the PCL-R, is tenuous at best.

In this interview, Robert Sapolsky outlines his view on Free Will and related topics. The discussion anticipates his upcoming book Determined: The Science of Life Without Free Will. Various topics are covered at the intersection of neuroscience with philosophy, education, and the criminal justice system.

This survey explores interactions between syntax and discourse, through a case study of patterns of extraction from coordinate structures. The theoretical breadth of the volume makes it the most complete account of extraction from coordinate structures to date: at first glance, it appears to be a syntactic matter, but the survey raises theoretical and empirical questions not just for syntax, but also across semantics, pragmatics, and discourse structure. Rather than promoting a single analysis, Daniel Altshuler and Robert Truswell (...) outline reasonable hypotheses that allow theoretical conclusions to be deducted from empirical facts. The theoretical conclusions show that coordinate structures have the potential to discriminate between current syntactic theories, and to inform work on the interfaces between syntax, semantics, pragmatics, and discourse. In many cases, however, the necessary empirical work has not yet been carried out, and too much of the literature revolves around the same handful of primarily English examples. The volume offers a starting point for further research on extraction from coordinate structures, particularly in understudied languages, and provides a guide to how to tease out the theoretical implications of empirical findings.

Chronic myeloid leukemia (CML) is a cancer of the hematopoietic system initiated by a single genetic mutation which results in the oncogenic fusion protein Bcr-Abl. Untreated, patients pass through different phases of the disease beginning with the rather asymptomatic chronic phase and ultimately culminating into blast crisis, an acute leukemia resembling phase with a very high mortality. Although many processes underlying the chronic phase are well understood, the exact mechanisms of disease progression to blast crisis are not yet revealed. In (...) this paper we develop a mathematical model of CML based on causal Bayesian networks in order to study possible disease progression mechanisms. Our results indicate that an increase of Bcr-Abl levels alone is not sufficient to explain the phenotype of blast crisis and that secondary changes such as additional mutations are necessary to explain disease progression and the poor therapy response of patients in blast crisis.
