Charles Parsons examines the notion of object, with the aim to navigate between nominalism, denying that distinctively mathematical objects exist, and forms of Platonism that postulate a transcendent realm of such objects. He introduces the central mathematical notion of structure and defends a version of the structuralist view of mathematical objects, according to which their existence is relative to a structure and they have no more of a 'nature' than that confers on them. Parsons also analyzes the concept (...) of intuition and presents a conception of it distantly inspired by that of Kant, which describes a basic kind of access to abstract objects and an element of a first conception of the infinite.

Terence Parsons presents a lively and controversial study of philosophical questions about identity. Because many puzzles about identity remain unsolved, some people believe that they are questions that have no answers and that there is a problem with the language used to formulate them. Parsons explores a different possibility: that such puzzles lack answers because of the way the world is (or because of the way the world is not). He claims that there is genuine indeterminacy of identity (...) in the world. He articulates such a view in detail and defends it from a host of criticisms. (shrink)

Terence Parsons presents a new study of the development and continuing value of medieval logic, which expanded Aristotle's basic principles of logic in important ways. Parsons argues that the resulting system is as rich as contemporary first-order symbolic logic.

This study examines the history of the psychoanalytic theory of mysticism, starting with the seminal correspondence between Freud and Romain Rolland concerning the concept of "oceanic feeling." Providing a corrective to current views which frame psychoanalysis as pathologizing mysticism, Parsons reveals the existence of three models entertained by Freud and Rolland: the classical reductive, ego-adaptive, and transformational (which allows for a transcendent dimension to mysticism). Then, reconstructing Rolland's personal mysticism (the "oceanic feeling") through texts and letters unavailable to Freud, (...) Parsons argues that Freud misinterpreted the oceanic feeling. In offering a fresh interpretation of Rolland's mysticism, Parsons constructs a new dialogical approach for psychoanalytic theory of mysticism which integrates culture studies, developmental perspectives, and the deep epistemological and transcendent claims of the mystics.

This provocative, focused, and succinct new text addresses two issues integral to the study of the philosophy of science: the rationality of science and the realism question. Students are invited to think deeply about salient issues as they explore collections of cases and examples, beginning by considering the founding document of modern science, Copernicus’s On the Revolutions of the Heavenly Spheres , and including discussions of other key readings such as Thomas Kuhn’s The Structure of Scientific Revolutions . Author Keith (...) Parsons challenges students’ thinking, offering his own views while providing a solid foundation for debate. (shrink)

Traditionally, analytic philosophers writing on aesthetics have given short shrift to nature. The last thirty years, however, have seen a steady growth of interest in this area. The essays and books now available cover central philosophical issues concerning the nature of the aesthetic and the existence of norms for aesthetic judgement. They also intersect with important issues in environmental philosophy. More recent contributions have opened up new topics, such as the relationship between natural sound and music, the beauty of animals, (...) and the aesthetics of gardens. Using these materials, it is now easy to include a module on the aesthetics of nature as one part of an introductory course on aesthetics, or even to design an entire upper-level undergraduate or graduate seminar around the topic.

Sample Syllabus for a three-week module in an undergraduate aesthetics course: This three week module can easily be adapted to fit shorter available class time or reduced reading expectations for students. A lighter two-week module, for instance, would drop the Hepburn reading and do either the Carroll essay or the Saito essay, but not both. Note that all readings for this module are reprinted in Allen Carlson and Arnold Berleant (eds.), The Aesthetics of Natural Environments (Peterborough, Ontario: Broadview Press, 2004). Week 1: Introduction Reading: Ronald Hepburn, 'Contemporary Aesthetics and the Neglect of Natural Beauty'. British Analytical Philosophy. Eds. Bernard Williams and Alan Montefiore (London: Routledge and Kegan Paul, 1966), 285–310. Discussion of Hepburn's essay will allow the instructor to bring out the distinctive issues and themes of the aesthetics of nature. Week 2: Objectivity or Subjectivity?

Landscape, Natural Beauty and the Arts. Eds. Salim Kemal and Ivan Gaskell (Cambridge: Cambridge University Press, 1993), 228–43. This section covers two very different approaches to thinking about the aesthetic appreciation of nature. Consideration of these provides an opportunity for students to reflect on nature's relationship to art, and on the character of aesthetic experience itself.

In this essay I respond to the critical remarks made by Prof. Reppert in “Reply to Parsons and Lippard on the Argument from Reason” (present issue). I also provide a critique of Reppert’s original article, “The Argument from Reason,” in Philo vol. 2, no. 1 (Spring-Summer 1999).

Talcott Parsons wrote this paper as a basis for discussion at the General Session: Analysis of the Sociological Profession organized within the frame of annual meeting of the American Sociological Society in Chicago. He sketched here some of the most urgent problems facing sociological profession. These problems can be broken down into four basic questions. The most central of these concerns the extent to which the canons of scientific objectivity have come to be established as the working code of (...) the profession in dealing with defined intellectual subject matters. The second concerns the present clarity of the differentiation from and relation to neighboring scientific disciplines, so that we can speak with certain definiteness about what, as distinct from other scientists, a sociologist does. The third question concerns the differentiation of sociology as a science from sociological “practice” and its proper relation to applied field. Finally, there is a problem of sociology’s differentiation as a scientific discipline and a relation to the non-scientific aspects of the general culture. (shrink)

The paper approaches the problem of rationality on the basis of the theory of action elaborated in ParsonsParsons, Talcott’ The Structure of Social Action of 1937. The voluntaristic action frame of reference, as it was called, implies the opportunity of choice in the course of actions. Predictability of the consequences of a course of action, as a prerequisite of choice, requires rational empirical knowledge and logical consistency. Choices are also dependent on norms and values, as well as on affective meanings, (...) the balancing of which requires complex calculations of costs and advantages or utilities. Appreciation of rational knowledge implies – and depends upon – a commitment to norms of rationality. The limits of rationality are set by irrationality in the sense of deviance from normative standards, but also by non-rational and non-logical factors such as tradition, religion, or art. The work of ParetoPareto, Vilfredo is taken as an important reference point as it is acknowledged to be “the most ambitious attempt to achieve a generalized formulation of a total social system of rational action.”.

Our technologies are progressively developing into algorithmic devices that seamlessly interface with digital personhood. This text discusses the ways in which technology is increasingly becoming a part of personhood and the resulting ethical issues. It extends upon the framework for a brain-based cyberpsychology outlined by the author's earlier book Cyberpsychology and the Brain: The Interaction of Neuroscience and Affective Computing. Using this framework, Thomas D. Parsons investigates the ethical issues involved in cyberpsychology research and praxes, which emerge in algorithmically (...) coupled people and technologies. The ethical implications of these ideas are important as we consider the cognitive enhancements that can be afforded by our technologies. If people are intimately linked to their technologies, then removing or damaging the technology could be tantamount to a personal attack. On the other hand, algorithmic devices may threaten autonomy and privacy. This book reviews these and other issues. (shrink)

The nature of psychoanalysis seems contradictory - deeply personal, subjective and intuitive, yet requiring systematic theory and principles of technique. The objective quality of psychoanalytic knowledge is paradoxically dependent on the personal engagement of the knower with what is known. In The Dove that Returns, The Dove that Vanishes , Michael Parsons explores the tension of this paradox. As they respond to it, and struggle to sustain it creatively, analysts discover their individual identities. The work of outstanding clinicians such (...) as Marion Milner and John Klauber is examined in detail. The reader also encounters oriental martial arts, Greek Tragedy, the landscape painting of John Constable, a Winnicottian theory of creativity and a discussion of the significance of play in psychoanalysis. From such varied topics evolves a deepening apprehension of the nature of the clinical experience. Illustrated throughout with clinical examples, The Dove that Returns, The Dove that Vanishes will prove valuable to those in the field of psychoanalysis, and to those in the arts and humanities who are interested in contemporary psychoanalytic thinking.

The following quotation, from Frank Jackson, is the beginning of a typical exposition of the debate between those metaphysicians who believe in temporal parts, and those who do not: The dispute between three-dimensionalism and four-dimensionalism, or more precisely, that part of the dispute we will be concerned with, concerns what persistence, and correllatively, what change, comes to. Three-dimensionalism holds that an object exists at a time by being wholly present at that time, and, accordingly, that it persists if it is (...) wholly present at more than one time. For short, it persists by enduring. Four-dimensionalism holds that an object exists at a time by having a temporal part at that time, and it persists if it has distinct temporal parts at more than one time. For short, it persists by perduring. In the light of these comments, some readers will perhaps find the question that forms the title of this paper a little puzzling. They may have learned to use the terms ‘fourdimensionalism’ ‘perdurantism’ and ‘belief in temporal parts’ interchangeably; or perhaps even to define one in terms of the other. Such a usage, however, is inapposite. We might imagine a Flatland-like world of two spatial dimensions and one temporal, whose philosophers are divided between a theory of persistence on which they persist by having temporal parts, and a theory on which they persist by being wholly located in each of several times. This is just the same issue we face, but at least the label ‘four-dimensionalism’ seems inapposite: the four-dimensionalist Flatlanders believe in only three dimensions! (shrink)

In his two recent books on ontology, Universals: an Opinionated Introduction, and A World of States of Affairs, David Armstrong gives a new argument against nominalism. That argument seems, on the face of it, to be similar to another argument that he used much earlier against Rylean behaviourism: the Truthmaker Argument, stemming from a certain plausible premise, the Truthmaker Principle. Other authors have traced the history of the truthmaker principle, its appearance in the work of Aristotle [10], Bradley [16], and (...) even Husserl [15]. But that is not my task — in this paper I argue that Armstrong’s new argument is not logically analogous to the old, and, in particular, that it is quite possible to be a thoroughgoing nominalist, and hold a truthmaker principle.

I consider different versions of a structuralist view of mathematical objects, according to which characteristic mathematical objects have no more of a 'nature' than is given by the basic relations of a structure in which they reside. My own version of such a view is non-eliminative in the sense that it does not lead to a programme for eliminating reference to mathematical objects. I reply to criticisms of non-eliminative structuralism recently advanced by Keränen and Hellman. In replying to the former, (...) I rely on a distinction between 'basic' and 'constructed' structures. A conclusion is that ideas from the metaphysical tradition can be misleading when applied to the objects of modern mathematics. (shrink)

I want to join Dummett in saying that the reality of the past (and, by analogy, the reality of the future) is an issue of realism versus anti-realism: (Dummett 1969) If you affirm the reality of the past, you are a realist about the past. If you deny the reality of the past, you are an anti-realist about the past. (And likewise, in each case, for the future). It makes sense to think of these issues by analogy with realism about (...) the external world, unobservable objects, mathematical objects, universals, and so on. These are all properly described as ontological issues. (shrink)

This entry traces the historical development of the Square of Opposition, a collection of logical relationships traditionally embodied in a square diagram. This body of doctrine provided a foundation for work in logic for over two millenia. For most of this history, logicians assumed that negative particular propositions ("Some S is not P") are vacuously true if their subjects are empty. This validates the logical laws embodied in the diagram, and preserves the doctrine against modern criticisms. Certain additional principles ("contraposition" (...) and "obversion") were sometimes adopted along with the Square, and they genuinely yielded inconsistency. By the nineteenth century an inconsistent set of doctrines was widely adopted. Strawson's 1952 attempt to rehabilitate the Square does not apply to the traditional doctrine; it does salvage the nineteenth century version but at the cost of yielding inferences that lead from truth to falsity when strung together.

Cognitivism about imperatives is the thesis that sentences in the imperative mood are truth-apt: have truth values and truth conditions. This allows cognitivists to give a simple and powerful account of consequence relations between imperatives. I argue that this account of imperative consequence has counterexamples that cast doubt on cognitivism itself.

In In Contradiction, Graham Priest shows, as clearly as anything like this can be shown, that it is coherent to maintain that some sentences can be both true and false at the same time. As a consequence, some contradictions are true, and an appreciation of this possibility advances our understanding of the nature of logic and language.

I argue that Colin Cheyne and Charles Pigden's recent attempt to find truthmakers for negative truths fails. Though Cheyne and Pigden are correct in their treatment of some of the truths they set out to find truthmakers for (such as 'There is no hippopotamus in S223' and 'Theatetus is not flying') they over-generalize when they apply the same treatment to 'There are no unicorns'. In my view, this difficulty is ineliminable: not every truth has a truthmaker.

An argument is usually said to be valid iff it is truth-preserving—iff it cannot be that all its premises are true and its conclusion false. But imperatives (it is normally thought) are not truth-apt. They are not in the business of saying how the world is, and therefore cannot either succeed or fail in doing so. To solve this problem, we need to find a new criterion of validity, and I aim to propose such a criterion.

This important book by a major American philosopher brings together eleven essays treating problems in logic and the philosophy of mathematics.

This paper presents an argument that the way we experience time is more consistent with our being instantaneous objects than with our being temporally extended throughout our entire lifetimes. By argument to the best explanation therefore, experiencing subjects persons are stages, rather than worms.

This study reports the results of a survey designed to assess the impact of business education on the ethical beliefs of business students. The study examines the beliefs of graduate and undergraduate students about ethical behavior in educational settings. The investigation indicates that the behavior which students learn or perceive is required to succeed in business schools may run counter to the ethical sanctions of society and the business community.

Trust is a natural mechanism by which an autonomous party, an agent, can deal with the inherent uncertainty regarding the behaviours of other parties and the uncertainty in the information it shares with those parties. Trust is thus crucial in any decentralised system. This paper builds on recent efforts to use argumentation to reason about trust. Specifically, a set of schemes is provided, and abstract patterns of reasoning that apply in multiple situations geared towards trust. Schemes are described in which (...) one agent, A, can establish arguments for trusting another agent, B, directly, as well as schemes that A can use to construct arguments for trusting C, where C is trusted by B. For both sets of schemes, a set of critical questions is offered that identify the situations in which these schemes can fail. (shrink)

Scientific cognitivism is the idea that nature must be aesthetically appreciated in light of scientific information about it. I defend Carlson's traditional formulation of scientific cognitivism from some recent criticisms. However, I also argue that if we employ this formulation it is difficult to uphold two claims that Carlson makes about scientific cognitivism: (i) it is the correct analysis of the notion of appropriate aesthetic appreciation of nature, and (ii) it justifies the idea that nature, seen aright, is always beautiful (...) (that is, positive aesthetics about nature). I attempt to find a revised formulation of scientific cognitivism that can support both of these claims. I argue that to do this we must rethink the notion of positive aesthetics and its place in our theorizing about the appropriate aesthetic appreciation of nature. Specifically, I propose that positive aesthetics be made ‘internal’ to the theory of appropriate aesthetic appreciation, in the sense that this theory determines the correct scientific categories for appreciating a natural object, in part, in virtue of a ‘beauty-making’ criterion. I argue that this sort of formulation of scientific cognitivism can support both of Carlson's claims and does not compromise the objectivist scruples that motivate the view. (shrink)

We present a logic-based formalism for modeling ofdialogues between intelligent and autonomous software agents,building on a theory of abstract dialogue games which we present.The formalism enables representation of complex dialogues assequences of moves in a combination of dialogue games, and allowsdialogues to be embedded inside one another.

The debate between A-theory and B-theory in the philosophy of time is a persistent one. It is not always clear, however, what the terms of this debate are. A-theorists are often lumped with a miscellaneous collection of heterodox doctrines: the view that only the present exists, that time flows relentlessly, or that presentness is a property (Williams 1996); that time passes, tense is unanalysable, or that earlier than and later than are defined in terms of pastness, presentness, and futurity (Bigelow (...) 1991); or that events or facts (as opposed to language) are “tensed” (Mellor 1993). B-theorists then argue that the A-theory is incoherent, using variants on J.M.E. McTaggart’s argument for the unreality of time (McTaggart 1927, ch. 33). (shrink)
