This paper examines the occurrence and impact of gender discrimination in access to production resources on the income, productivity, and technical efficiency of farmers. Through an empirical investigation of farmers from Koussin-Lélé, a semi-collective irrigated rice scheme in central Benin, we find that female rice farmers are particularly discriminated against with regard to scheme membership and access to land and equipment, resulting in significant negative impacts on their productivity and income. Although women have lower productivity, they are as technically efficient (...) as men. The findings suggest that there is considerable scope for improving the productivity of women through increasing their access to production resources. (shrink)

The interventionist account of causal explanation, in the version presented by Jim Woodward, has been recently claimed capable of buttressing the widely felt—though poorly understood—hunch that high-level, relatively abstract explanations, of the sort provided by sciences like biology, psychology and economics, are in some cases explanatorily optimal. It is the aim of this paper to show that this is mistaken. Due to a lack of effective constraints on the causal variables at the heart of the interventionist causal-explanatory scheme, as presently (...) formulated it is either unable to prefer high-level explanations to low, or systematically overshoots, recommending explanations at so high of a level as to be virtually vacuous.

In this paper I seek to defend libertarianism about free will and moral responsibility against two well-known arguments: the luck argument and the Mind argument. Both of these arguments purport to show that indeterminism is incompatible with the degree of control necessary for free will and moral responsibility. I begin the discussion by elaborating these arguments, clarifying important features of my preferred version of libertarianism—features that will be central to an adequate response to the arguments—and showing why a strategy of (...) reconciliation (often referred to as “deliberative libertarianism”) will not work. I then consider four formulations of the luck argument and find them all wanting. This discussion will place us in a favorable position to understand why the Mind argument also fails. (shrink)

Philosophers of experiment have acknowledged that experiments are often more than mere hypothesis-tests, once thought to be an experiment's exclusive calling. Drawing on examples from contemporary biology, I make an additional amendment to our understanding of experiment by examining the way that `wide' instrumentation can, for reasons of efficiency, lead scientists away from traditional hypothesis-directed methods of experimentation and towards exploratory methods.

Libertarianism has, seemingly, always been in disrepute among philosophers. While throughout history philosophers have offered different reasons for their dissatisfaction with libertarianism, one worry is recurring: namely a worry about luck. To many, it seems that if our choices and actions are undetermined, then we cannot control them in a way that allows for freedom and responsibility. My fundamental aim in this paper is to place libertarians on a more promising track for formulating a defensible libertarian theory. I begin by (...) arguing that Robert Kane's influential formulation of libertarianism actually generates an acute worry about luck, showing specifically that Kane's recipe for solving the problem of luck and his attendant conception of the location and role of indeterminism derived from it are deeply problematic. I then offer a reformulation of libertarianism ? particularly a new conception of the location and role of indeterminism ? that is capable of avoiding the problems that beset Kane's theory and that, I argue, places libertarians on a more promising track for formulating a defensible theory.

The classical arguments for scepticism about the external world are defended, especially the symmetry argument: that there is no reason to prefer the realist hypothesis to, say, the deceitful demon hypothesis. This argument is defended against the various standard objections, such as that the demon hypothesis is only a bare possibility, does not lead to pragmatic success, lacks coherence or simplicity, is ad hoc or parasitic, makes impossible demands for certainty, or contravenes some basic standards for a conceptual or linguistic (...) scheme. Since the conclusion of the sceptical argument is not true, it is concluded that one can only escape the force of the argument through some large premise, such as an aptitude of the intellect for truth, if necessary divinely supported.

This paper provides an overview of results from an Australian Research Council-funded project "Sentiments and Risks: The Changing Nature of Human-Animal Relations in Australia." The data discussed come from a survey of 2000 representative Australians at the capital city, state, and rural regional level. It provides both a snapshot of the state of involvement of Australians with nonhuman animals and their views on critical issues: ethics, rights, animals as food, risk from animals, native versus introduced animals, hunting, fishing, and companionate (...) relations with animals. Its data point to key trends and change. The changing position of animals in Australian society is critical to understand, given its historic export markets in meat and livestock, emerging tourism industry with its strong wildlife focus, native animals' place in discourses of nation, and the centrality of animal foods in the national diet. New anxieties about risk from animal-sourced foods and the endangerment of native animals from development and introduced species, together with tensions between animals' rights and the privileging of native species, contribute to the growth of a strongly contested animal politics in Australia. © 2007 Brill Academic Publishers.

"Does torture work?" is a factual rather than ethical or legal question. But legal and ethical discussions of torture should be informed by knowledge of the answer to the factual question of the reliability of torture as an interrogation technique. The question as to whether torture works should be asked before that of its legal admissibility—if it is not useful to interrogators, there is no point considering its legality in court.

We investigate the relationship between lowness for Schnorr randomness and Schnorr triviality. We show that a real is low for Schnorr randomness if and only if it is Schnorr trivial and hyperimmune free.

Brains, unlike artificial neural nets, use symbols to summarise and reason about perceptual input. But unlike symbolic AI, they “ground” the symbols in the data: the symbols have meaning in terms of data, not just meaning imposed by the outside user. If neural nets could be made to grow their own symbols in the way that brains do, there would be a good prospect of combining neural networks and symbolic AI, in such a way as to combine the good features (...) of each. The article argues the cluster analysis provides algorithms to perform the task, and that any solution to the task must be a form of cluster analysis. (shrink)

In the target article, Baars has offered both a theory of consciousness and a strategy for scientifically testing the theory. This commentary is intended as an addendum. I'd like to suggest implementing global workspace agents as both an additional strategy toward scientific testing, and as a means of fleshing out the theory.

Both philosophical and practical analyses of global justice issues have been vitiated by two errors: a too-high emphasis on the supposed duties of collectives to act, and a too-low emphasis on the analysis of causes and risks. Concentrating instead on the duties of individual actors and analysing what they can really achieve reconfigures the field. It diverts attention from individual problems such as poverty or refugees or questions on what states should do. Instead it shows that there are different duties (...) for political leaders, intelligence operatives, opinion leaders and citizens in devising, urging and implementing such plans as transfers of aid with accountability, military interventions in rogue states and limited intakes of refugees. With collectivist excuses for inaction such as sovereignty out of the way, it is possible to take a cautiously optimistic view of the possibility of forceful and morally responsible interventions in the range of major global problems.

Postmodernism is not so much a theory as an attitude. It is an attitude of suspicion – suspicion about claims of truth and about appeals to rational argument. Its corrupting effects must be answered by finding a better alternative, which must include a defence of the objecvity of both reason and ethics. Natural law thinking is necessary for the latter.

The views of some historians and philosophers of history as to the possibility of fruitful historical generalization seem at odds with the underlying methodology of the other social sciences. A formal model of the world historical process is here presented within which this apparent contradiction is seen to be resolvable in terms of modern theories of probability and stochastic processes. This is done by giving rigorous form to procedures and statements in the social sciences. A formal treatment of the dependence (...) of an investigation in one discipline on previous studies both in that area and in other social and natural sciences then follows naturally. (shrink)

In Marshall's Tendencies (Sutton, 2000), John Sutton poses some fairly deep questions for economists, especially for empirical work. In particular, when (if ever) is it safe to behave as though the applies? In that paradigm, we are attempting to extract and estimate the model from the data and are only kept from doing so because, while economic analysis captures the main , there are many small influences that we cannot exactly take into account. That paradigm, which Sutton traces to an (...) analogy of Marshall's likening economic predictions to predictions of the tides, leads to the econometric estimation of economic relationships, taking statistical account of the unincluded small influences by placing them in a random disturbance term. Sutton states (p. 5),. (shrink)

Talk about ethics involves a great number of different sorts of concepts – rules, virtues, values, outcomes, rights, etc … Ethics is about all those things, but it is not fundamentally about them. Let’s review them with a view to seeing why they are not basic.

In this paper I examine the roles that experiment plays in science. Experiment can test theories, but it can also call for a new theory. Experiment can also provide hints about the mathematical form of a theory. Likewise it can provide evidence for the existence of the entities involved in our theories. Finally, it may also have a life of its own, independent of theory. I will illustrate these roles using episodes from the history of contemporary physics. I will also (...) discuss an epistemology of experiment, a set of strategies that provides grounds for reasonable belief in experimental results. (shrink)

How does the physics community deal with the subsequent work of a scientist whose earlier work has been regarded as incorrect? An interesting case of this involves Joseph Weber whose claim to have observed gravitational waves was rejected by virtually all of the physics community, although Weber himself continued to defend his work until his death in 2000. In the course of this defense Weber made a startling suggestion regarding the scattering of neutrinos. I will summarize the history of gravity (...) waves including the rejection of Weber's claim around 1975, his later work on gravity waves, and examine the reaction of the physics community to his neutrino hypothesis.----------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- ---------------------------------------------------.

The composition series of Verma modules and homomorphisms between Verma modules in the case of a complex semisimple Lie algebra were studied by Verma and by Bernstein, Gelfand and Gelfand. The author studies homomorphisms between the Verma modules in characteristic p.

This is the most thorough philosophical analysis available of the principle of religious freedom. It draws on the thought of philosophers and political theorists (Rawls, Habermas, Murray, Rorty, Greenawalt, and Mead) rather than on the framers of the Constitution and the Bill of Rights.

This paper reports original data on contentious challenges, especially protests, focused on human rights in seven Latin American countries from 1981 to 1995. An analysis reveals that human rights contentious challenges are most prevalent where human rights abuses are worse and authoritarianism is present and in countries that are more urbanized. However, the incidence of such human rights contentious challenges is not related to the number of human rights organizations in the country. Results also suggest two different types of human (...) rights contention. National human rights movements, present in Argentina and Guatemala, involved HROs and demanded improvements in the national human rights situation. The other form is ancillary human rights protest, in which human rights challenges are led by a variety of groups, focus on repression particular to the groups involved and are either short-lived or part of a more general wave of opposition. This form of contention was more prevalent in Brazil, Chile, Mexico, Nicaragua, and Venezuela. (shrink)

An Aristotelian Philosophy of Mathematics breaks the impasse between Platonist and nominalist views of mathematics. Neither a study of abstract objects nor a mere language or logic, mathematics is a science of real aspects of the world as much as biology is. For the first time, a philosophy of mathematics puts applied mathematics at the centre. Quantitative aspects of the world such as ratios of heights, and structural ones such as symmetry and continuity, are parts of the physical world and (...) are objects of mathematics. Though some mathematical structures such as infinities may be too big to be realized in fact, all of them are capable of being realized. Informed by the author's background in both philosophy and mathematics, but keeping to simple examples, the book shows how infant perception of patterns is extended by visualization and proof to the vast edifice of modern pure and applied mathematical knowledge.

Both realist and anti-realist accounts of natural kinds possess prima facie virtues: realists can straightforwardly make sense of the apparent objectivity of the natural kinds, and anti-realists, their knowability. This paper formulates a properly anti-realist account designed to capture both merits. In particular, it recommends understanding natural kinds as ‘categorical bottlenecks,’ those categories that not only best serve us, with our idiosyncratic aims and cognitive capacities, but also those of a wide range of alternative agents. By endorsing an ultimately subjective (...) categorical principle, this view sidesteps epistemological difficulties facing realist views. Yet, it nevertheless identifies natural kinds that are fairly, though not completely, stance-independent or objective. (shrink)

"Mitchell Franklin (1902-1986) is described by the Buffalo Law Review as the foremost Marxist legal philosopher in the English-speaking world. In these selected writings, Franklin, a professor of law at Tulane University for 37 years, discusses how the development of natural law from an idealist to a materialist concept in the transition from feudalism to capitalism is reflected in the drafting of the U.S. Constitution and its interpretation today" --Publisher's summary.

Recent discussions of emergence in physics have focussed on the use of limiting relations, and often particularly on singular or asymptotic limits. We discuss a putative example of emergence that does not fit into this narrative: the case of phonons. These quasi-particles have some claim to be emergent, not least because the way in which they relate to the underlying crystal is almost precisely analogous to the way in which quantum particles relate to the underlying quantum field theory. But there (...) is no need to take a limit when moving from a crystal lattice based description to the phonon description. Not only does this demonstrate that we can have emergence without limits, but also provides a way of understanding cases that do involve limits. (shrink)

Among the factors necessary for the occurrence of some event, which of these are selectively highlighted in its explanation and labeled as causes — and which are explanatorily omitted, or relegated to the status of background conditions? Following J. S. Mill, most have thought that only a pragmatic answer to this question was possible. In this paper I suggest we understand this ‘causal selection problem’ in causal-explanatory terms, and propose that explanatory trade-offs between abstraction and stability can provide a principled (...) solution to it. After sketching that solution, it is applied to a few biological examples, including to a debate concerning the ‘causal democracy’ of organismal development, with an anti-democratic (though not a gene-centric) moral.

Why was Leibniz so fascinated by Chinese philosophy and culture? What specific forms did his interest take? How did his interest compare with the relative indifference of his philosophical contemporaries and near-contemporaries such as Spinoza and Locke? In this highly original book, Franklin Perkins examines Leibniz's voluminous writings on the subject and suggests that his interest was founded in his own philosophy: the nature of his metaphysical and theological views required him to take Chinese thought seriously. Leibniz was unusual (...) in holding enlightened views about the intellectual profitability of cultural exchange, and in a broad-ranging discussion Perkins charts these views, their historical context, and their social and philosophical ramifications. The result is an illuminating philosophical study which also raises wider questions about the perils and rewards of trying to understand and learn from a different culture. (shrink)
