Abstract: Advances in cognitive neuroscience make cosmetic neurology in some form inevitable and will give rise to extremely difficult ethical issues.

Abstract: In this paper, I raise the following problem: How does Avicenna define modalities? What oppositional relations are there between modal propositions, whether quantified or not? After giving Avicenna's definitions of possibility, necessity and impossibility, I analyze the modal oppositions as they are stated by him. This leads to the following results: 1. The relations between the singular modal propositions may be represented by means of a hexagon. Those between the quantified propositions may be represented by means of two hexagons that one could relate to each other. 2. This is so because the exact negation of the bilateral possible, i.e. 'necessary or impossible' is given and applied to the quantified possible propositions. 3. Avicenna distinguishes between the scopes of modality which can be either external (de dicto) or internal (de re). His formulations are external unlike al-F̄ar̄ab̄;’s ones. However his treatment of modal oppositions remains incomplete because not all the relations between the modal propositions are stated explicitly. A complete analysis is provided in this paper that fills the gaps of the theory and represents the relations by means of a complex figure containing 12 vertices and several squares and hexagons.

Abstract: In this article, I analyze Quine's conception of science, which is a radical defence of extensionalism on the grounds that first?order logic is the most adequate logic for science. I examine some criticisms addressed to it, which show the role of modalities and probabilities in science and argue that Quine's treatment of probability minimizes the intensional character of scientific language and methods by considering that probability is extensionalizable. But this extensionalizing leads to untenable results in some cases and is not consistent with the fact that Quine himself admits confirmation which includes probability. Quine's extensionalism does not account for this fact and then seems unrealistic, even if science ought to be extensional in so far as it is descriptive and mathematically expressible.

Abstract:

A source of tension between Philosophers of Mathematics and Mathematicians is the fact that each group feels ignored by the other; daily mathematical practice seems barely affected by the questions the Philosophers are considering. In this talk I will describe an issue that does have an impact on mathematical practice, and a philosophical stance on mathematics that is detectable in the work of practising mathematicians. No doubt controversially, I will call this issue ‘morality’, but the term is not of my coining: there are mathematicians across the world who use the word ‘morally’ to great effect in private, and I propose that there should be a public theory of what they mean by this. The issue arises because proofs, despite being revered as the backbone of mathematical truth, often contribute very little to a mathematician’s understanding. ‘Moral’ considerations, however, contribute a great deal. I will first describe what these ‘moral’ considerations might be, and why mathematicians have appropriated the word ‘morality’ for this notion. However, not all mathematicians are concerned with such notions, and I will give a characterisation of ‘moralist’ mathematics and ‘moralist’ mathematicians, and discuss the development of ‘morality’ in individuals and in mathematics as a whole. Finally, I will propose a theory for standardising or universalising a system of mathematical morality, and discuss how this might help in the development of good mathematics.

Publisher's Note: Charles Chihara's new book develops and defends a structural view of the nature of mathematics, and uses it to explain a number of striking features of mathematics that have puzzled philosophers for centuries. The view is used to show that, in order to understand how mathematical systems are applied in science and everyday life, it is not necessary to assume that its theorems either presuppose mathematical objects or are even true. Chihara builds upon his previous work, in which he presented a new system of mathematics, the constructibility theory, which did not make reference to, or presuppose, mathematical objects. Now he develops the project further by analysing mathematical systems currently used by scientists to show how such systems are compatible with this nominalistic outlook. He advances several new ways of undermining the heavily discussed indispensability argument for the existence of mathematical objects made famous by Willard Quine and Hilary Putnam. And Chihara presents a rationale for the nominalistic outlook that is quite different from those generally put forward, which he maintains have led to serious misunderstandings. A Structural Account of Mathematics will be required reading for anyone working in this field. generally put forward, which he maintains have led to serious misunderstandings.

Summary: Introduction to mathematical nominalism, with special attention to Chihara's own development of the position and the objections of John Burgess and Gideon Rosen. Chihara provides an outline of his constructibility theory, which avoids quantification over abstract objects by making use of contructibility quantifiers which instead of making assertions about what exists, make assertions about what sentences can be constructed.

Publisher’s Note:

The issue of a logic foundation for African thought connects well with the question of method. Do we need new methods for African philosophy and studies? Or, are the methods of Western thought adequate for African intellectual space? These questions are not some of the easiest to answer because they lead straight to the question of whether or not a logic tradition from African intellectual space is possible. Thus in charting the course of future direction in African philosophy and studies, one must be confronted with this question of logic. The author boldly takes up this challenge and becomes the first to do so in a book by introducing new concepts and formulating a new African culture-inspired system of logic called Ezumezu which he believes would ground new methods in African philosophy and studies. He develops this system to rescue African philosophy and, by extension, sundry fields in African Indigenous Knowledge Systems from the spell of Plato and the hegemony of Aristotle. African philosophers can now ground their discourses in Ezumezu logic which will distinguish their philosophy as a tradition in its own right. On the whole, the book engages with some of the lingering controversies in the idea of (an) African logic before unveiling Ezumezu as a philosophy of logic, methodology and formal system. The book also provides fresh arguments and insights on the themes of decolonisation and Africanisation for the intellectual transformation of scholarship in Africa. It will appeal to philosophers and logicians—undergraduates and post graduate researchers—as well as those in various areas of African studies.

Summary: The use of models to scientifically represent and study reality is widely recognized with good reasons as indispensable for the practice of science. Because models, unlikely pure verbal representation, are justifiably regarded as vehicles of representation that are not truth-apt, philosophical questions are natural raised concerning the nature of such vehicles and how they represent. A sizeable literature generated in recent years explores the possibility that ''scientific models are works of fiction''. Idealization and other similar strategies are often taken to be the means by which models are made. Arguing against this last claim, the thesis of this article is that most models in science are not fictional. The author argues against the idea that idealization is the means by which models of typically unobservable systems or mechanisms are made.

Abstract: Comment: Churchland argues that advances in neuroscience should should bring about reform in a number of central areas of philosophy. Formal logic does not model human reasoning, formal semantics cannot account for how human language is meaningful, there are no foundations of knowledge, there is no a priori knowledge, and true belief is not a goal of human nervous systems.

Diversifying Syllabi: Churchland claims that experimental science has gradually (and rightfully and successfully) replaced philosophical investigations of the world, and suggests that the time has come for philosophy of mind and moral philosophy to “cede” to experimental science. She claims that conceptual analysis has been undermined by “a torrent of neuro­psychological results” that contradict folk psychology (i.e. intuition). Thus, self­respecting philosophers of mind have begun to engage with experimental science. Moral philosophers have not yet realized that their field is going in the same direction, and that their stories are about to be superceded by a “naturalistic framework for looking at human morality and decision making” (409). She gives some examples from animal studies bearing on social behaviour and organization like monogamy, trust and cooperation, social attachment, group cooperation or amalgamation. One central point is that moral rules play only a partial role, if at all, in the “brain’s decision” when faced with “constraint­satisfaction problems” (410).

Publisher's Note: Progress in the neurosciences is profoundly changing our conception of ourselves. Contrary to time-honored intuition, the mind turns out to be a complex of brain functions. And contrary to the wishful thinking of some philosophers, there is no stemming the revolutionary impact that brain research will have on our understanding of how the mind works. Brain-Wise is the sequel to Patricia Smith Churchland's Neurophilosophy, the book that launched a subfield. In a clear, conversational manner, this book examines old questions about the nature of the mind within the new framework of the brain sciences. What, it asks, is the neurobiological basis of consciousness, the self, and free choice? How does the brain learn about the external world and about its own introspective world? What can neurophilosophy tell us about the basis and significance of religious and moral experiences? Drawing on results from research at the neuronal, neurochemical, system, and whole-brain levels, the book gives an up-to-date perspective on the state of neurophilosophy - what we know, what we do not know, and where things may go from here.

Abstract:

This entry presents the framework of « dialogical logic » in the initial Lorenzen and Lorenz tradition. The rules for the game and for building strategies are provided with step by step examples, helping the reader understand how the dialogue tables reflect a dynamic process of interaction between the players. Various logics are presented within this pluralistic framework: intuitionist logic, classical logic, and modal logics, with references to various other logics. In a second part of the entry, objections against the framework are considered, together with answers provided by the « Immanent Reasoning » variant, which stays within the Lorenzen and Lorenz tradition, and by the « Built-In Opponent » variant first developed by Catarina Dutilh Novaes, which develops a different dialogical tradition.

Abstract: Empiricism in the form of quantitative methods has sometimes been used by researchers to thwart human welfare and social justice. Some of the ugliest moments in the history of psychology were a result of researchers using quantitative methods to legitimize and codify the prejudices of the day. This has resulted in the view that quantitative methods are antithetical to the pursuit of social justice for oppressed and marginalized groups. While the ambivalence toward quantitative methods by some is understandable given their misuse by some researchers, we argue that quantitative methods are not inherently oppressive. Quantitative methods can be liberating if used by multiculturally competent researchers and scholar-activists committed to social justice. Examples of best practices in social justice oriented quantitative research are reviewed.

Abstract: Black women have long occupied marginal positions in academic settings. I argue that many Black female intellectuals have made creative use of their marginality their "outsider within " status-to produce Black feminist thought that reflects a special standpoint on self family, and society. I describe and explore the sociological significance of three characteristic themes in such thought: (1) Black women's self-definition and self-valuation; (2) the interlocking nature of oppression; and (3) the importance of Afro-American women's culture. After considering how Black women might draw upon these key themes as outsiders within to generate a distinctive standpoint on existing sociological paradigms, I conclude by suggesting that other sociologists would also benefit by placing greater trust in the creative potential of their own personal and cultural biographies.

Abstract: "Women have been largely excluded from the work of producing the forms of thought and the images and symbols in which thought is expressed and ordered," suggests sociologist Dorothy E. Smith. "We can imagine women's exclusion organized by the formation of a circle among men who attend to and treat as significant only what men say." In this male discourse, "what men were doing was relevant to men, was written by men about men for men . . . this is how a tradition is formed" (Smith 1987, p. 18). Smith's perspective aptly describes the outer circle that delineates sociology from other equally male-centered disciplines, but it also characterizes the important inner circle of sociological theory lying at the center of the field.
