I argue in §1 that there is a clear distinction between predicate negation and sentential negation and that sentential negation is a special case of predicate negation operating on the predicate ‘is true’. In §2 I reply to Richard’s objections to negative properties on the basis of the conception of properties as identity conditions presented in Chapter 12 of Logical Forms.

In §1 I reply to Jairo’s objections to my account of truth and falsity showing that my account of falsity does not imply that false sentences refer to something. In §2 I argue that Jairo’s main objection to my account of propositions as abstract properties is based on a misunderstanding concerning the purpose of this account. In §3 I examine Jairo’s suggestion that contradictory sentences can be said to describe possible states of affairs.

José Seoane centers his commentary on my critique of the standard formal analysis of proof as an elucidation of the informal notion of proof, and I basically agree with his considerations throughout the paper. In my response I argue that the notion of formal proof is fundamentally an analysis of the notion of logical consequence, rather than an elucidation of the informal notion of proof. O comentário de José Seoane está centrado na crítica da análise formal de prova como elucidação (...) da noção informal de prova, e estou basicamente de acordo com suas considerações. Em minha réplica argumento que a noção de prova formal é fundamentalmente uma análise da noção de conseqüência lógica ao invés de uma elucidação da noção informal de prova. (shrink)

_History of Psychology: A Cultural Perspective_ easily distinguishes itself from other texts in a number of ways. First, it examines the field within the rich intellectual and cultural context of everyday life, cross-cultural influences, and contributions from literature, art, and other disciplines. Second, it is a history of ideas, concepts, and questions, instead of dates, events, or great minds. Third, the book explores the history of applied, developmental, clinical, and cognitive psychology as well as experimental psychology. Conveyed in a lively (...) writing style, this text tells a gripping story that continues to the present day. Its current perspective allows students to connect the history of the field to the work being published in current journals. O’Boyle writes in the “historical present”, giving readers a sense of immediacy and aliveness as they journey through history. Her account uses imaginative new features, including “The Times”, which gives readers a feel for what everyday life was like during the age discussed in the chapter. Descriptions of ordinary life, as well as information about important issues influencing their lives such as wars, social movements, famines, and plagues, pique students' interest. "Stop and Think" questions, scattered throughout, enhance retention and encourage critical thinking. An ideal text for a history of psychology or history and systems of psychology course, this creative new book will also appeal to those with a general interest in the field. The Instructor’s Resource CD, written by the text author, includes class activities and demonstrations, suggestions for small group and class discussions, a list of films and videos related to the material in each chapter, and a test bank with objective and essay questions.

The paper by Jairo José da Silva is mainly concerned with the character of mathematical proof and with the nature of mathematics and its ontology. Although there is a fair amount of agreement in our views, I focus my response on three issues on which we disagree. The first is his view of mathematical proof as generally unconstrained by language and by a previous proof apparatus. The second is his discussion of Brouwer’s views on proof and formalization. The third is (...) his nominalistic account of structuralism.O artigo de Jairo José da Silva explora principalmente o caráter das provas matemáticas e a natureza ontológica da matemática. Apesar de haver bastante concordância em nossos pontos de vista, o foco de minha réplica são três questões em que discordamos. A primeira é sua visão da prova matemática como completamente livre de restrições impostas pela linguagem e por um aparato prévio de prova. A segunda é sua discussão de Brouwer em relação à prova e à formalização. A terceira é sua formulação nominalista do estruturalismo. (shrink)

Анализируя основные идеи представителей феноменологической психиатрии и экзистенциального анализа и выстраивая панораму их формирования и развития, автор включает рассматриваемую традицию в философский контекст XX века.

Rather surprisingly, T.H.Green's ideas on women and the family are as neglected today as they were immediately after his death in 1882, when his thought was first interpreted for a wider public by his colleagues and friends.1 Silence on such matters in the 1880s is not remarkable. It is odd, however, that it persists today, despite recent intense concern with the history of women and the family, including their place in political thought, and despite reviving philosophical interest in the British (...) Idealists and readiness to credit them with a significant impact on politics, education and social work. It has often been remarked that Green's political ideas have much in common superficially with those of John Stuart Mill, since their values and precepts are very similar, although the substructure of their thought is utterly different. Nevertheless it has altogether escaped notice that this is equally true of their ideas on women, marriage and family relationships. Today Mill's fabled feminism easily appears limited and imperceptive, and the priority he gave to the parliamentary vote strangely simplistic. Did Green show any greater realism and understanding? Did he practise as well as preach real equality between men and women, in private as well as public life? In short, what precisely was Green's position on 'the woman question'�? (shrink)

In my response to Guillermo Rosado-Haddock I discuss the two main issues raised in his paper. The first is that by allowing Henkin’s general models as a legitimate model-theoretic interpretation of second-order logic, I undermine my defense of second-order logic against Quine’s views concerning the primacy of first-order logic. The second is that my treatment of logical truth and logical properties does not take into account various systems of logic and properties of systems of logic such as the Löwenheim-Skolem property.Em (...) minha réplica à Guillermo Rosado-Haddock discuto as duas questões centrais levantadas em seu artigo. A primeira é que ao permitir modelos gerais de Henkin como uma interpretação legítima da lógica de segunda ordem, desvirtuo minha defesa da lógica de segunda ordem contra a visão de Quine respeito à primazia da lógica de primeira ordem. A segunda é que meu tratamento da verdade lógica e das propriedades lógicas não leva em consideração diversos sistemas de lógica e propriedades de sistemas de lógica tais como a propriedade de Löwenheim-Skolem.

Quons are particles characterized by the parameter q, which permits smooth interpolation between Bose and Fermi statistics; q = 1 gives bosons, q = -1 gives fermions. In this paper we give a heuristic argument for an extension of conservation of statistics to quons with trilinear couplings of the form ffb, where f is fermion-like and b is boson-like. We show that q f 2 = qb. In particular, we relate the bound on qγ for photons to the bound on (...) qe for electrons, allowing the very precise bound for electrons to be carried over to photons. An extension of this argument suggests that all particles are fermions or bosons to a high precision. (shrink)

This book offers a novel approach to teacher education through the philosophy of education. The book is structured around the themes of Voice, Risk, and Care, wherein the author engages with the philosophy of Stanley Cavell, Gert Biesta, and Nel Noddings respectively, to develop six central capabilities of the educator: Acknowledgement and Autobiography, Imagination and Interruption, and Attention and Uncertainty. The work culminates in a final chapter proposing that the essential, unifying capability that new educators should be supported towards is (...) The Ordinary. This book will appeal to those interested and engaged in initial teacher education, practising educators, and those engaged in the professional development and support of educators from early years to higher education.

This paper explains why spacetime singularities do not constitute a breakdown of physical laws, and points out that the difference between the metrics at singularities and those outside of singularities is factual, rather than nomological.

This article explores the implications of the Harm Principle, modified to accommodate recent criticisms by Arthur Ripstein, for theories of distributive justice. It concludes that the resulting Sovereignty Principle leads to a left-libertarian theory of justice that is based not on egalitarianism but rather on considerations internal to the Principle itself. This theory avoids criticisms of incoherence that have been rightly applied to other recent versions of left-libertarianism, and supports a requirement of substantial redistribution without necessarily precluding further redistribution for (...) reasons other than those of justice.

William James' lecture on "The Will to Believe" has kindled spirited controversy. In this reappraisal of that controversy, Father O'Connell contributes some : that James' argument should be viewed against his indebtedness to Pascal and Renouvier; that it works primarily to validate our "over-beliefs" ; and most surprising perhaps, that James envisages our "passional nature" as intervening, not after, but before and throughout, our intellectual weighing of the evidence for belief. --From publisher's description.

The 2021 Gifford Lectures by Oliver O'Donovan evaluate the state of ethics as a discipline and its relationship to theology.

In §1 I examine the connections between my account of logical properties and Tarski’s account of logical notions. In §2 I briefly present some of my views on modality and the basis for my claim that there are intensional as well as extensional relations between properties. In §3 I compare my views on the nature of logic and of mathematics with Gödel’s views.

In this paper I examine arguments by Benacerraf and by Chihara against Gödel’s platonistic philosophy of mathematics.Neste artigo examino argumentos de Benacerraf e de Chihara contra a filosofia platônica da matemática de Gödel.
