One of the major adaptations during the evolution of Homo sapiens was an increase in brain size. Here we present evidence that a significant and substantial proportion of variation in brain size may be related to changes in temperature. Based on a sample of 109 fossilized hominid skulls, we found that cranial capacities were highly correlated with paleoclimatic changes in temperature, as indexed by oxygen isotope data and sea-surface temperature. Indeed, as much as 52% of the variance in the cranial (...) capacity of these skulls could be accounted for by temperature variation at 100 ka intervals. As an index of more short-term seasonal fluctuations in temperature, we examined the latitude of the sites from which the crania originated. More than 22% of the variance in cranial capacity of these skulls could be accounted for by variation in equatorial distance. (shrink)

We argue that cognitive empathy and other instances of mental state attribution are a byproduct of self-awareness. Evidence is brought to bear on this proposition from comparative psychology, early child development, neuropsychology, and abnormal behavior.

Using a sample of 652 college students, we examined several implications of the hypothesis that the shape of the human penis evolved to enable males to substitute their semen for those of their rivals. The incidence of double mating by females appears sufficient to make semen displacement adaptive (e.g., one in four females acknowledge infidelity, one in eight admit having sex with two or more males in a 24-hour period, and one in 12 report involvement in one or more sexual (...) threesomes with two males). We also document several changes in post-ejaculatory behavior (e.g., reduced thrusting, penis withdrawal, loss of an erection) which may have evolved to minimize displacement of the male’s own semen. Consistent with predictions derived from a theoretical model (Gallup and Burch 2006), we discovered that most females report waiting at least 48 hours following an instance of infidelity before resuming sex with their in-pair partners.

The data reviewed in Barresi & Moore's treatment of social understanding is recast in terms of a model of social intelligence that was advanced some time ago (Gallup 1982). When it comes to their analysis of the behavior of other individuals, most primates (and humans younger than 18 months of age) appear to function as radical behaviorists, whereas chimpanzees and older infants show evidence of becoming primitive cognitive psychologists.

Heyes's attempt to reinterpret research on primate cognition from the standpoint of radical behaviorism is strong on dialogue and debate but weak on evidence. Recent evidence concerning self-recognition, for example, shows that her arguments about differential recovery from anesthetization and species differences in face touching as alternative accounts of the behavior of primates in the presence of mirrors) are invalid.

This article focuses on mirror self-recognition, the ability to recognize one's own image in a mirror. It presents the result of the first experiment on mirror self-recognition which showed that chimpanzees are able to learn that the chimps they see in the mirror are not other chimps, but themselves, as evidenced by self-directed behaviour. It reviews evidence for neural network for self-recognition and self-other differentiation and cites evidence that frontal cortex and cortical midline structures are implicated in self-recognition tasks. It (...) also suggests that the mirror self-recognition ability correlates to large brain size relative to the animal's body size. (shrink)

Aspects of Northoff's argument lend themselves to the ongoing investigation of localizing the self in the brain. Recent data from the fields of neuropsychology and cognitive neuroscience provide evidence that the right hemisphere is a candidate for localization of self. The data on catatonia further that proposition and add insight into the continuing investigation of self in the brain across sensory and motor domains.

I said that the book is brilliant. This is not so much because of the conclusions eventually reached about the inadequacy of a purely naturalistic approach to mind. These conclusions are already familiar in the work of Donald Davidson and others. Rather, it is because of the accumulation of historical detail and insight on the basis of which these conclusions are reached. It is often said, for instance, that Kant is a watershed figure, in some sense synthesizing and then moving (...) beyond both empiricism and naturalism. Hatfield uses these terms. But he reinvests them with meaning and energy and in the process shows how radical Kant was in refocusing, by way of a sharp distinction between empirical and transcendental inquiries, the central questions of philosophy.

Traditional accounts stress certain features of theoretical objects such as their alleged imperceptibility, that are taken to raise epistemological difficulties. But these accounts do not show how theoretical objects, rightly understood, either differ in kind from more ordinary sorts of objects or make science possible. I sketch a new account that focuses on the underdetermination and similarity of theoretical objects, features closely connected to the explanatory roles they play, and construes them on an algebraic model.

Numerous searches have failed to identify a single co-occurrence of total blindness and schizophrenia. Evidence that blindness causes loss of certain NMDA-receptor functions is balanced by reports of compensatory gains. Connections between visual and anterior cingulate NMDA-receptor systems may help to explain how blindness could protect against schizophrenia.

The US neutrino community gathered at the Workshop on the Intermediate Neutrino Program at Brookhaven National Laboratory February 4-6, 2015 to explore opportunities in neutrino physics over the next five to ten years. Scientists from particle, astroparticle and nuclear physics participated in the workshop. The workshop examined promising opportunities for neutrino physics in the intermediate term, including possible new small to mid-scale experiments, US contributions to large experiments, upgrades to existing experiments, R&D plans and theory. The workshop was organized into (...) two sets of parallel working group sessions, divided by physics topics and technology. Physics working groups covered topics on Sterile Neutrinos, Neutrino Mixing, Neutrino Interactions, Neutrino Properties and Astrophysical Neutrinos. Technology sessions were organized into Theory, Short-Baseline Accelerator Neutrinos, Reactor Neutrinos, Detector R&D and Source, Cyclotron and Meson Decay at Rest sessions.This report summarizes discussion and conclusions from the workshop.

While interest in Kant's philosophy has increased in recent years, very little of it has focused on his theory of science. This book gives a general account of that theory, of its motives and implications, and of the way it brought forth a new conception of the nature of philosophical thought. To reconstruct Kant's theory of science, the author identifies unifying themes of his philosophy of mathematics and philosophy of physics, both undergirded by his distinctive logical doctrines, and shows how (...) they come together to form a relatively consistent system of ideas. A new analysis of the structure of central arguments in the Critique of Pure Reason and the Prolegomena draws on recent developments in logic and the philosophy of science. Professor Brittan's unified account of the philosophies of mathematics and physics explores the nature of Kant's commitment to Euclidean geometry and Newtonian mechanics as well as providing an integrated reading of the Critique of Pure Reason and the Metaphysical Foundations of Natural Science. Contemporary ideas help both to illuminate Kant's position and to show how that position, in turn, illuminates contemporary problems in the philosophy of science. Originally published in 1978. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

The economic and moral defense of sweatshops given by Powell and Zwolinski has been criticized in two recent papers. Coakley and Kates focus on putative weaknesses in the logic of Powell’s and Zwolinski’s argument. Preiss :55–82, 2014) argues that, even granting the validity of their economic argument, Powell’s and Zwolinski’s defense is without force when viewed from a Kantian republican viewpoint. We are concerned that sweatshop critics have misinterpreted the economic literature and overstated the conclusions that follow from their ethical (...) premises. We show that the best understanding of the current economic literature supports Powell’s and Zwolinski’s conclusions about the negative effects of sweatshop wage regulation, and that it is unreasonable to reject economic analysis in moral argument against sweatshops even from a Kantian perspective. Additionally, we defend the theory of exploitation as unfairness given by Wertheimer, and show how economic analysis can be applied to that theory to identify cases of sweatshop exploitation.

Science is made possible by the introduction of theoretical objects. Why this should be so has never been made clear. Indeed, it has never been made clear how theoretical objects are rightly to be understood, or in what ways they differ from more ordinary sorts of physical objects. What follows is a sketch of a new theory. In my view, this theory becomes explicit on the so-called “Copenhagen interpretation” of quantum mechanics. But it has implicitly characterized scientific development since the (...) revolution of the 16th and 17th centuries.How are theoretical objects rightly to be understood? I say that they are objects whose existence is postulated by a theory is alright as far as it goes, but it doesn’t go far enough. We also need to know what theories are. (shrink)

Excerpt“We are now living in a totally new era,” Henry Kissinger said in May 2022 in an interview with the Financial Times)1.

Arnold and Bowie (2003) attempt to derive ethical constraints on the actions of the managers of multinational enterprises (MNEs), orthe MNEs themselves, from a Kantian perspective. We contest Arnold and Bowie’s claims regarding MNE duties, in particular that MNEs have a duty to pay a subsistence wage above market levels. We conclude that even within Arnold and Bowie’s Kantian framework such a duty does not properly emerge. In addition, we argue that the account of coercion used by Arnold and Bowie (...) does not serve their purposes. Arnold and Bowie address consequentialist issues by arguing that their conclusions are not undercut by economic considerations regarding unemployment. We argue that Arnold and Bowie have misread the economic literature in this regard. (shrink)

Abstract:In contrast to “social contract” theories of the corporation, a moral justification of the corporation as actual, not hypothetical, agreement is presented. Central to the justification is the idea of personal projects, as developed by Loren Lomasky. The key idea is the role that corporations can play in the construction and advancement of personal, value-creating projects. The concept of the corporation as actual agreement, as a type of “right of association” theory, is defended against influential criticism of such theories by (...) Thomas Donaldson. (shrink)
