Previously published as special issues of _The European Journal of the History of Economic Thought_ and _The Review of Political Economy_, this volume contains the papers devoted to the life and work of Piero Sraffa. Sraffa was a leading intellectual of the twentieth century. He was brought to Cambridge by John Maynard Keynes and had an important impact on the philosopher Ludwig Wittgenstein. He received the golden medal Söderström of the Swedish Academy of Sciences for his edition of David (...) Ricardo's _Works and Correspondence_ and he is the author of _Production of Commodities by Means of Commodities_, one of the most often cited book in economics. Using hitherto unpublished material from Sraffa's literary heritage kept at Trinity College, Cambridge, the papers throw new light on the intellectual development of the young Sraffa and correct several of the received views on him and his contribution. Themes covered concern his: objectivism rediscovery and reformulation of the classical theory of value and distribution criticism of Alfred Marshall's analysis relationship with his Cambridge colleagues and friends biography around the time when he left Italy for the UK friendship with Wittgenstein and his impact on the latter's thinking.

In their recent paper in this journal, Heinz and colleagues accuse proponents of cognitive enhancement of making two unjustified assumptions. The first of these is the assumption that neuroenhancing drugs will be safe; the second is that research into cognitive enhancement does not pose particular ethical problems. Heinz and colleagues argue that both these assumptions are false. Here, I argue that these assumptions are in fact correct, and that Heinz and colleagues themselves make several assumptions that undermine (...) their argument. Neuroenhancement does raise several ethical concerns, but safety and research in this area pose no unique difficulties. (shrink)

Pompey has been treacherously killed, his body decapitated and thrown into the surf. The faithful Cornelia cannot give her husband a proper funeral, but must be content to place on the pyre all that is left of his greatness. Commentators are not of much help in this place, most caught up in tralatician glossing and hence content to echo the scholiastic reference to Pompey's three triumphs. Thomas Farnaby thought of the funeral of Misenus in Aeneid 6; but one looks in (...) vain to Grotius , Oudendorp , Burman , Bentley , Weber , Francken , Heitland-Haskins , Housman , Bourgery-Ponchont , and Luck for the most important parallel, which is to Dido in Aeneid. I adduce the passages Heinze well described as examples of ‘das Idealbild eines heroischen Weibes’: tu secreta pyram tecto interiore sub auras erige, et arma uiri thalamo quae fixa reliquit impius exuuiasque omnis lectumque iugalem, quo perii, super imponas: 494–7) super exuuias ensemque relictum effigiemque toro locat haud ignata futuri. hie, postquam Iliacas uestis notumque cubile conspexit, paulum lacrimis et mente morata incubuitque toro dixitque nouissima uerba: ‘dulces exuuiae…’.

This junior/senior level text is devoted to a study of first-order logic and its role in the foundations of mathematics: What is a proof? How can a proof be justified? To what extent can a proof be made a purely mechanical procedure? How much faith can we have in a proof that is so complex that no one can follow it through in a lifetime? The first substantial answers to these questions have only been obtained in this century. The most (...) striking results are contained in Goedel's work: First, it is possible to give a simple set of rules that suffice to carry out all mathematical proofs; but, second, these rules are necessarily incomplete - it is impossible, for example, to prove all true statements of arithmetic. The book begins with an introduction to first-order logic, Goedel's theorem, and model theory. A second part covers extensions of first-order logic and limitations of the formal methods. The book covers several advanced topics, not commonly treated in introductory texts, such as Trachtenbrot's undecidability theorem. Fraissé's elementary equivalence, and Lindstroem's theorem on the maximality of first-order logic. (shrink)

From religion to philosophy to science, all human systems of definition are formed by human brains. The nature and limits of the human brain are the nature and limits of those systems. This essay shows how the human brain works normally then unusually, and what this reveals about the limits of human knowledge. There are many conditions and instances where the brain processes information unusually, including mental disorders, physical events, and drug use. This essay focuses on the neurological events called (...) mystical experiences. (shrink)

In Thomas Thomson's System of chemistry of 1802 Bergman and Scheele are actually considered as creators of the analytical concept of an element. With regard to this, a detailed investigation of the work of Bergman and Scheele shows that Thomson's statement contains mistakes as well as inadmissable simplifications and generalizations. It is correct, however, that Bergman in 1774–1777 specifically anticipated in essential aspects the analytical element concept proposed by Lavoisier in 1787–1789.

This short peer-reviewed text is a concise look at the psychology of how human beings make decisions, including how they form their worldviews and make arguments.

This paper aims to provide two abductive considerations adducing in favor of the thesis of Necessitism in modal ontology. I demonstrate how instances of the Barcan formula can be witnessed, when the modal operators are interpreted 'naturally' -- i.e., as including geometric possibilities -- and the quantifiers in the formula range over a domain of natural, or concrete, entities and their contingently non-concrete analogues. I argue that, because there are considerations within physics and metaphysical inquiry which corroborate modal relationalist claims (...) concerning the possible geometric structures of spacetime, and dispositional properties are actual possible entities, the condition of being grounded in the concrete is consistent with the Barcan formula; and thus -- in the geometric setting -- merits adoption by the Necessitist.

This is one of the most important books on quantum mechanics ever written for lay readers, in which an eminent physicist and successful science writer, Heinz Pagels, discusses and explains the core concepts of physics without resorting to complicated mathematics.

Part of the appeal of the biological approach to personal identity is that it does not have to countenance spatially coincident entities. But if the termination thesis is correct and the organism ceases to exist at death, then it appears that the corpse is a dead body that earlier was a living body and distinct from but spatially coincident with the organism. If the organism is identified with the body, then the unwelcome spatial coincidence could perhaps be avoided. It is (...) argued that such an identification would be a mistake. A living organism has a different part/whole relationship and persistence conditions than the alleged body. A case will be made that the concept ‘human body’ is a conceptual mess, vague in an unprincipled manner, and that an eliminativist stance towards dead bodies is the appropriate response.

Oxford Philosophical Texts Series Editor: John Cottingham The Oxford Philosophical Texts series consists of authoritative teaching editions of canonical texts in the history of philosophy from the ancient world down to modern times. Each volume provides a clear, well laid out text together with a comprehensive introduction by a leading specialist, giving the student detailed critical guidance on the intellectual context of the work and the structure and philosophical importance of the main arguments. Endnotes are supplied which provide further commentary (...) on the arguments and explain unfamiliar references and terminology, and a full bibliography and index are also included. The series aims to build up a definitive corpus of key texts in the Western philosophical tradition, which will form a reliable and enduring resource for students and teachers alike. David Hume's aim in writing An Enquiry concerning Human Understanding was to introduce his philosophy to a European culture in which many educated people read original works of philosophy. He gives an elegant and accessible presentation of strikingly original and challenging views about the limited powers of human understanding, the attractions of scepticism, the compatibility of free will and determinism, and weaknesses in the foundations of religion. Hume's philosophy was highly controversial in the eighteenth century and remains so today. The text printed in this edition is that of the Clarendon critical edition of Hume's works. A substantial introduction by the editor explains the intellectual background to the work and surveys its main themes. The volume also includes detailed explanatory notes on the text, a glossary of terms, a full list of references, and a section of supplementary readings. (shrink)

As a continuation of the work of the third author in [5], we make further observations on the features of Galois cohomology in the general model theoretic context. We make explicit the connection between forms of definable groups and first cohomology sets with coefficients in a suitable automorphism group. We then use a method of twisting cohomology (inspired by Serre’s algebraic twisting) to describe arbitrary fibres in cohomology sequences—yielding a useful “finiteness” result on cohomology sets. Applied to the special case (...) of differential fields and Kolchin’s constrained cohomology, we complete results from [3] by proving that the first constrained cohomology set of a differential algebraic group over a bounded, differentially large, field is countable.

Der auf Kants kritischer Philosophie fußenden Philosophengeneration galt Herder als hoffnungslos anachronistischer, vorkritischer Philosoph, dessen Denken für das eigene philosophische Programm keine Relevanz zukomme. Das im folgenden dokumentierte Projekt geht demgegenüber von der Hypothese aus, daß Herder in die Vorgeschichte der Philosophie des deutschen Idealismus gehört, daß er Vorläufer und Weggenosse der nachkantischen Philosophengeneration war. Der vorliegende Band versammelt Arbeiten, die zur Begründung und Diskussion dieser Auffassung in unterschiedlicher Weise beitragen: es geht um die Konturierung der für diese Thematik relevanten (...) Aspekte von Herders eigenem Denken, um die Erschließung der gemeinsamen philosophischen und wissenschaftshistorischen Grundlagen des Herderschen Denkens und der Philosophie des deutschen Idealismus, nicht zuletzt geht es um die Erarbeitung der Rezeption von Herders Philosophie in der nachkantischen Philosophengeneration.
