Do we have introspective access to our own thoughts? Peter Carruthers challenges the consensus that we do: he argues that access to our own thoughts is always interpretive, grounded in perceptual awareness and sensory imagery. He proposes a bold new theory of self-knowledge, with radical implications for understanding of consciousness and agency.

Since its original publication in 1975, this groundbreaking work has awakened millions of people to the existence of "speciesism"—our systematic disregard of nonhuman animals—inspiring a worldwide movement to transform our attitudes to animals and eliminate the cruelty we inflict on them. In Animal Liberation, author Peter Singer exposes the chilling realities of today’s "factory farms" and product-testing procedures—destroying the spurious justifications behind them, and offering alternatives to what has become a profound environmental and social as well as moral issue. (...) An important and persuasive appeal to conscience, fairness, decency, and justice, it is essential reading for the supporter and the skeptic alike. (shrink)

If culture is defined as variation acquired and maintained by social learning, then culture is common in nature. However, cumulative cultural evolution resulting in behaviors that no individual could invent on their own is limited to humans, song birds, and perhaps chimpanzees. Circumstantial evidence suggests that cumulative cultural evolution requires the capacity for observational learning. Here, we analyze two models the evolution of psychological capacities that allow cumulative cultural evolution. Both models suggest that the conditions which allow the evolution of (...) such capacities when rare are much more stringent than the conditions which allow the maintenance of the capacities when common. This result follows from the fact that the assumed benefit of the capacities, cumulative cultural adaptation, cannot occur when the capacities are rare. These results suggest why such capacities may be rare in nature. (shrink)

Human social life is uniquely complex and diverse. Much of that complexity consists of culturally transmitted ideas and skills that underpin the operation of institutions that structure our social life. Considerable theoretical and empirical work has been devoted to the role of cultural evolutionary processes in the evolution of institutions. The most persistent controversy has been over the role of cultural group selection and gene-culture coevolution in early human populations the Pleistocene. We argue that cultural group selection and related cultural (...) evolutionary processes had an important role in shaping the innate components of our social psychology. By the Upper Paleolithic humans seem to have lived in societies structured by institutions, as do modern populations living in simple societies. The most ambitious attempts to test these ideas have been the use of experimental games in field settings to document human similarities and differences on theoretically interesting dimensions. These studies have documented a huge range of behavior cross-culturally, although no societies so far examined follow the expectations of selfish rationality. These data are at least consistent with operation of cultural group selection and gene-culture coevolution operating in the deep tribal past and with the contemporary importance of cultural evolution in the evolution of institutions and institutional diversity.

In 1936, G. Birkhoff and J. v. Neumann published an article with the title The logic of quantum mechanics'. In this paper, the authors demonstrated that in quantum mechanics the most simple observables which correspond to yes-no propositions about a quantum physical system constitute an algebraic structure, the most important proper ties of which are given by an orthocomplemented and quasimodular lattice Lq. Furthermore, this lattice of quantum mechanical proposi tions has, from a formal point of view, many similarities with (...) a Boolean lattice L8 which is known to be the lattice of classical propositional logic. Therefore, one could conjecture that due to the algebraic structure of quantum mechanical observables a logical calculus Q of quantum mechanical propositions is established, which is slightly different from the calculus L of classical propositional logic but which is applicable to all quantum mechanical propositions. This calculus has sometimes been called 'quan tum logic'. However, the statement that propositions about quantum physical systems are governed by the laws of quantum logic, which differ from ordinary classical logic and which are based on the empirically well-established quantum theory, is exposed to two serious objec tions: Logic is a theory which deals with those relationships between various propositions that are valid independent of the content of the respective propositions. Thus, the validity of logical relationships is not restricted to a special type of proposition, e. g. to propositions about classical physical systems. (shrink)

Issues about the creation of works, what is essential and inessential to their identity, their distinct kinds of properties, including aesthetic properties, ...

This chapter examines the extent to which there are continuities between the cognitive processes and epistemic practices engaged in by human hunter-gatherers, on the one hand, and those which are distinctive of science, on the other. It deploys anthropological evidence against any form of 'no-continuity' view, drawing especially on the cognitive skills involved in the art of tracking. It also argues against the 'child-as-scientist' accounts put forward by some developmental psychologists, which imply that scientific thinking is present in early infancy (...) and universal amongst humans who have sufficient time and resources to devote to it. In contrast, a modularist kind of 'continuity' account is proposed, according to which the innately channelled architecture of human cognition provides all the materials necessary for basic forms of scientific reasoning in older children and adults, needing only the appropriate sorts of external support, social context, and background beliefs and skills in order for science to begin its advance.

New developments in reproductive technology have made headlines since the birth of the world's first in vitro fertilization baby in 1978. But is embryo experimentation ethically acceptable? What is the moral status of the early human embryo? And how should a democratic society deal with so controversial an issue, where conflicting views are based on differing religious and philosophical positions? These controversial questions are the subject of this book, which, as a current compendium of ideas and arguments on the subject, (...) makes an original contribution of major importance to this debate.

This paper details the ontological and epistemic character of activties that occur in mechanisms. It explains why they are sufficient to handle the problems of causation.

Progress Unchained reinterprets the history of the idea of progress using parallels between evolutionary biology and changing views of human history. Early concepts of progress in both areas saw it as the ascent of a linear scale of development toward a final goal. The 'chain of being' defined a hierarchy of living things with humans at the head, while social thinkers interpreted history as a development toward a final paradise or utopia. Darwinism reconfigured biological progress as a 'tree of life' (...) with multiple lines of advance not necessarily leading to humans, each driven by the rare innovations that generate entirely new functions. Popular writers such as H. G. Wells used a similar model to depict human progress, with competing technological innovations producing ever-more rapid changes in society. Bowler shows that as the idea of progress has become open-ended and unpredictable, a variety of alternative futures have been imagined. (shrink)

Included is a famous nineteenth-century debate about scientific reasoning between the hypothetico-deductivist William Whewell and the inductivist John Stuart Mill; and an account of the realism-antirealism dispute about unobservables in science, with a consideration of Perrin's argument for the existence of molecules in the early twentieth century.

This chapter is offered as a contribution to the logic of down below. We attempt to demonstrate that the nature of human agency necessitates that there actually be such a logic. The ensuing sections develop the suggestion that cognition down below has a structure strikingly similar to the physical structure of quantum states. In its general form, this is not an idea that originates with the present authors. It is known that there exist mathematical models from the cognitive science of (...) cognition down below that have certain formal similarities to quantum mechanics. We want to take this idea seriously. We will propose that the subspaces of von Neumann-Birkhoff lattices are too crisp for modelling requisite cognitive aspects in relation to subsymbolic logic. Instead, we adopt an approach which relies on projections into nonorthogonal density states. The projection operator is motivated from cues which probe human memory. (shrink)

Martin Heidegger is widely regarded as one of the most influential philosophers of the twentieth-century, and his seminal text Being and Time is considered one of the most significant texts in contemporary philosophy. Yet his name has also been mired in controversy because of his affiliations with the Nazi regime, his failure to criticize its genocidal politics and his subsequent silence about the holocaust. Now, according to Heidegger's wishes, and to complete the publication of his multi-volume Complete Works, his highly (...) controversial and secret 'Black Notebooks' have been released to the public. These notebooks reveal the extent to which Heidegger's 'personal Nazism' was neither incidental nor opportunistic, but part of his philosophical ethos. So, why would Heidegger, far from destroying them, allow these notebooks, which contain examples of this extreme thinking, to be published? In this revealing new book, Peter Trawny, editor of Heidegger's complete works in German, confronts these questions and, by way of a compelling study of his theoretical work, shows that Heidegger was committed to a conception of freedom that is only beholden to the judgement of the history of being; that is, that to be free means to be free from the prejudices, norms, or mores of one's time. Whoever thinks the truth of being freely exposes themselves to the danger of epochal errancy. For this reason, Heidegger's decision to publish his notebooks, including their anti-Jewish passages, was an exercise of this anarchical freedom. In the course of a wide-ranging discussion of Heidegger's views on truth, ethics, the truth of being, tragedy and his relationship to other figures such as Nietzsche and Schmitt, Trawny provides a compelling argument for why Heidegger wanted the explosive material in his Black Notebooks to be published, whilst also offering an original and provocative interpretation of Heidegger's work.

Early modern experimental philosophers were opposed to speculation, and yet many endorsed speculative theories. This chapter gives a partial explanation of why this is so, using Robert Boyle’s acceptance and promotion of the corpuscular philosophy as a case study. It argues that, in addition to furnishing experimental evidence for the corpuscular hypothesis in his Forms and Qualities, Boyle attempted to establish its epistemic superiority over other speculative theories on the grounds that it is founded upon superior principles. In his ‘Excellency (...) and Grounds of the Mechanical Hypothesis’, Boyle claims that the principles of the corpuscular philosophy are more intelligible, more parsimonious, ontologically primary, simpler and more comprehensive than those of its rivals. On grounds of comparative plausibility then, according to Boyle, the corpuscular philosophy is eminently preferable to its rivals. The final section of the chapter traces the legacy of Boyle’s appraisal of the epistemic status of the corpuscular philosophy in the writings of many of his compatriots from the mid-1660s to the Cyclopedia of Ephraim Chambers of 1728.

In his doctoral dissertation Von der mannigfachen Bedeutung des Seienden nach Aristoteles Brentano tried to show that (against criticism of this) one could indeed give a principle defense of Aristotle's table of categories as a coherent system. In later texts Brentano appears sharply critical of Aristotle, mainly in respect to Aristotle's mereology, or theory of part and whole, and to his theory of substance and accident. It is argued that Brentano hadn't observed that Aristotle's belief that there are as many (...) predicative senses of 'be' as there are categories of being is based not on his mereology but on his theory of definition. Overlooking this Brentano was led to far reaching inadequate ontological consequences. (shrink)

I reply to commentaries by Justin Bruner, Robert Sugden and Gerald Gaus. My response to Bruner focuses on conventions of bargaining problems and arguments for characterizing the just conventions of these problems as monotone path solutions. My response to Sugden focuses on how the laws of humanity present in Hume’s discussion of vulnerable individuals might be incorporated into my own proposed account of justice as mutual advantage. My response to Gaus focuses on whether or not my account of justice as (...) mutual advantage can incorporate deep differences in values across subgroups of a larger society. (shrink)

This volume brings historians of science and social historians together to consider the role of "little tools"--such as tables, reports, questionnaires, dossiers, index cards--in establishing academic and bureaucratic claims to authority and objectivity. From at least the eighteenth century onward, our science and society have been planned, surveyed, examined, and judged according to particular techniques of collecting and storing knowledge. Recently, the seemingly self-evident nature of these mundane epistemic and administrative tools, as well as the prose in which they are (...) cast, has demanded historical examination. The essays gathered here, arranged in chronological order by subject from the late seventeenth to the late twentieth century, involve close readings of primary texts and analyses of academic and bureaucratic practices as parts of material culture. The first few essays, on the early modern period, largely point to the existence of a "juridico-theological" framework for establishing authority. Later essays demonstrate the eclipse of the role of authority per se in the modern period and the emergence of the notion of "objectivity." Most of the essays here concern the German cultural space as among the best exemplars of the academic and bureaucratic practices described above. The introduction to the volume, however, is framed at a general level the closing essays also extend the analyses beyond Germany to broader considerations on authority and objectivity in historical practice. The volume will interest scholars of European history and German studies as well as historians of science. Peter Becker is Professor of Central European History, European University Institute.

L'analisi dell'aristotelismo «platonizzante» nell'ambito della filosofia araba prima della sistemazione della Shifa di Avicenna, secondo cui Dio non avrebbe conoscenza dei particolari, consente all'A. di dimostrare come ci siano stati anche approcci platonici ad Aristotele , che non sono passati attraverso il filtro dei neoplatonici greci. L'altra cosa significativa è il fatto che all'interno della scuola di Baghdad vi sono modi diversi di intendere lo stato ontologico degli universali. L'A. tenta anche di ridimensionare la figura di al-Farabi all'interno della scuola (...) di Baghdad. I filosofi considerati sono al-Farabi, Yahya b. Adi e Ibn al-Tayyib. (shrink)

I argue that common nouns should be analyzed as variables, rather than as predicates which take variables as arguments. This necessitates several unusual features to the analysis, such as allowing variables to be modally non-rigid, and assigning their values compositionally. However, treating common nouns as variables offers a variety of theoretical and empirical advantages over a more traditional analysis: It predicts the conservativity of nominal quantification, simplifies the analysis of articleless languages, derives the weak reading of sentences with donkey anaphora, (...) solves the proportion problem presented by quantifiers like ‘most’, improves the analysis of the temperature paradox, allows a more unified analysis of bare plurals, and regularizes the correspondence between syntactic categories and semantic types.

Drawing on implications from ethics, theology, law, politics, and education, this book argues that we can decide what is right by describing particular cases in detail, without the aid of ethical theories and principles.
