SummaryIntense, sustained nursing lengthens inter-birth intervals and is causally linked with low natural fertility. However, in traditional settings, the effects of such nursing on fertility are difficult to disentangle from those of nutrition. Results from an prospective, direct observational study of reproductive function in well-nourished Amele women who nurse intensively and persistently but who also have high fertility are here presented. Endocrine measures show that ovarian activity resumes by median 11·0 months postpartum. Median duration of postpartum amenorrhoea is 11·3 months, (...) time to next conception is 19·0 months, and the inter-birth interval is 28·0 months. Average life time fertility is 6·8. High fertility in Amele women is due both to refractoriness of reproductive function to suckling stimuli, and to maintenance of equivalent age-specific fertility rates across the reproductive life span.

Quartz & Sejnowski (Q&S) disregard evidence that suggests that their view of dendrites is inadequate and they ignore recent results concerning the role of neurotrophic factors in synaptic remodelling. They misrepresent neuronal selectionism and thus erect a straw-man argument. Finally, the results discussed in section 4.2 require neuronal proliferation, but this does not occur during the period of neuronal development of relevance here.

Scholars have debated the meaning of the foreign-relations clauses in the U.S. Constitution. This essay attempts to outline the foreign-relations clauses that an ideal constitution should have. A liberal constitution must enable the government to implement a morally defensible foreign policy. The first priority is the defense of liberty. The constitution must allow the government to effectively defend persons, territory, and liberal institutions themselves. The liberal government should also contribute to the advancement of global freedom, subject to a number of (...) conditions, especially cost. The essay recommends improved methods to incorporate treaties and customary international law into the constitutional structure. Treaties should be approved by the whole legislature and should generally be self-executing. Customary law should be genuine, not fake, and consistent with liberal principles. Finally, based on economic theory and evidence, the essay recommends that liberal constitutions prohibit the government from erecting trade barriers. It concludes by tentatively proposing concrete constitutional language to implement these recommendations. (shrink)
Kur’ân ve hadislerde geçen müteşâbih ifadelerin nasıl anlaşılacağına dair kelâm geleneğinde ciddi tartışmalar yaşanmış ve farklı ekollere mensup âlimler tarafından birçok eser yazılmıştır. Mâtürîdî bir âlim olan Nâsırüddîn es-Semerkandî de bu çalışmada tenkitli neşri sunulan Fethu’l-ğalak fi’t-tevhîd adlı eseri kaleme almıştır. Günümüze ulaşan Arapça elyazması Süleymaniye Kütüphanesi Fatih koleksiyonunda 3142 demirbaş numarasıyla bulunmaktadır. Bildiğimiz kadarıyla bu alanda müstakil olarak kaleme alınmış olup günümüze ulaşan tek Mâtürîdî eser olma özelliğine sahiptir. Akıl ve şeriatten hareketle yapılması gerektiğini savunduğu te’vîlin belirli ilkeler çerçevesinde (...) özellikle de luğavî anlamın dışına çıkmadan müteşâbih ifadelerin muhkemlere hamlederek yapılması gerektiğini belirtmektedir. Bu noktada çizdiği çerçevede olmayan ve uç noktalar olarak gördüğü Bâtinîlerin ve Hanbelîlerin te’vîl anlayışlarını da eleştirmektedir. Müteşâbih ifadeleri te'vîl etmeyi uygun gören Mâtürîdî-Hanefî geleneğin yaklaşımını ortaya koymasının yanında geç bir dönemde yazılan eser bu konuda ele alınan ifadelerin yorumuna dair zengin ve bilgilendirici bir içerik sunmakta ve müteşâbihlerin bütünsel anlaşılması yönünde imkân sağlamaktadır. Bu çalışma kapsamında müteşâbihe dair bir giriş, es-Semerkândî’nin hayatı ve eserin tenkitli neşri dikkatlere sunulacaktır. (shrink)

Why should sovereign states obey international law? What compels them to owe allegiance to a higher set of rules when each country is its own law of the land? What is the basis of their obligations to each other? Conventional wisdom suggests that countries are too different from one another culturally to follow laws out of mere loyalty to each other or a set of shared moral values. Surely, the prevailing view holds, countries act simply out of self-interest, and they (...) eventually consent to norms of international law to regulate matters of common interest.In this groundbreaking book, Fernando Tesón goes against this prevailing thought by arguing, in the Kantian tradition, that a shared respect for individual human rights underpins not just the obligation countries feel to follow international law but also international laws themselves and even the very legitimacy of nations in the eyes of the international community. Tesón, both a lawyer and a philosopher, proposes that an overlapping respect for human rights has created a moral common ground among the countries of the world; and moreover, that such an outlook is the only one that is rationally defensible. It is this common set of values rather than self-interest that ultimately provides legitimacy to international law. Using the tools of moral philosophy, Tesón analyzes the concepts of sovereignty, intervention, and national interest; the contributions of social contact theory, game theory, and feminist theory; and the puzzles of self-determination and group rights.More than simply outlining his theory, Tesón goes on to give detailed examples of international laws, international institutions, and their human rights foundations, putting his ideas to work and addressing legal reforms called for by the theory. He suggests that treaties, for example, should be considered binding if, and only if, the consent to the treaty was given by a genuinely representative government, one that acts out of interest for the human rights of its citizens. Although the theoretical achievement of this book is to challenge received wisdom on the foundation of international law, the practical ambition is a call to reform the international legal system for the post–Cold War era, to substitute for the old order one that gives primacy to human dignity and freedom over state power.

President George W. Bush surprised many observers in his second inaugural address when he promised to oppose tyranny and oppression, and this in a world not always willing or ready to join in that fight. Humanitarian intervention is again on the forefront of world politics.
Abstract The article addresses three aspects of the humanitarian intervention doctrine. It argues, first, that the value of sovereignty rests on the justified social processes of the target state ? the horizontal contract. Foreign interventions, even when otherwise justified, must respect the horizontal contract. In contrast, morally objectionable social processes (such as the subjection of women) are not protected by sovereignty (intervention, of course, may be banned for other reasons). In addition, tyrants have no moral protection against interventions directed at (...) them. Second, the article addresses the internal legitimacy of humanitarian intervention. It concludes that the liberal state may only use voluntary soldiers (either the voluntary army or mercenaries) to conduct humanitarian intervention. Conscription for that purpose is not permissible. The article shows that the long-standing criticism of mercenaries stems from a romantic prejudice and is thus unfair. Third, the article makes a distinction between intention (the determination to perform an action) and motive (a further goal that the agent seeks with that action) and shows that only intention is relevant for humanitarian intervention. A justified humanitarian intervention requires the intention to liberate the victims, but not necessarily a good further motive. It shows how mainstream doctrine has impermissibly confused the two concepts. (shrink)
Economists generally agree that free trade leads to economic growth. This proposition is supported both by theoretical models and empirical data. Further, while the empirical evidence is more limited on this question, the general consensus among economists holds that trade restrictions are likely to hurt the poor. Even if the latter consensus turns out to be wrong, if free trade leads to superior growth, governments would have more resources to redistribute to the poor. It is surprising then that philosophers and (...) human rights scholars do not advocate liberalizing trade as a way to improve the welfare of the poor as a class. While many scholars in these fields are silent with respect to the effect of free trade on the poor, some actually argue that liberalized trade is harmful for the poor, contrary to the claims of economists. In this article, we argue that any serious scholar concerned with the plight of the poor needs to address the theory and evidence regarding the effects of trade liberalization on economic growth, suggesting that the standard policy prescriptions of the philosophers and human rights scholars are, at best, of second order concern and, at worst, likely to be counterproductive in terms of improving the welfare of the poor.

When is humanitarian intervention legitimate and how should such interventions be conducted? This article sets out eight liberal principles that underlie humanitarian intervention, some of them abstract principles of international ethics and others more concrete principles that apply specifically to humanitarian intervention. It argues that whilst these principles do not determine the legitimacy of particular interventions, they should ?incline? our judgments towards approval or disapproval. The basic principles include the liberal idea that governments are the mere agents of the people, (...) that tyrannical governments forfeit their legal protections, that human rights entail obligations for governments, that justifiable intervention must intend the end of tyranny or anarchy, that the doctrine of double-effect should be respected, that intervention is only warranted in severe cases, that intervention be welcomed by those it is intended to save, and that ideally it is welcomed by the community of democratic states.

When can a group legitimately form its own state? Under international law, some groups can but others cannot. But the standard is unclear, and traditional legal analysis has failed to elucidate it. In The Theory of Self-Determination, leading scholars chart new territory in our theoretical conception of self-determination. Drawing from diverse scholarship in international law, philosophy, and political science, they attempt to move beyond the prevailing nationalist conceptions of group definition. At issue are such universal questions as: when does a (...) group qualify as a 'people'? Does history matter? Or is it a question of ethnic status? Are these matters properly solved by popular vote? Anchored in modern analytical political philosophy but with implications for a wide range of scholarship, this volume will prove essential for scholars and practitioners of international law, global justice, and international relations.

:This essay argues that the territorial rights of states derive from the property rights of the individuals that make up those states. The argument draws from the Lockean tradition of justification of political powers. Persons in the state of nature have natural rights. Those rights are first-order substantive rights, and second-order executive rights In the social contract, individuals transfer to the state their executive rights, not their substantive rights. The state can thus define the boundaries of property rights and adjudicate (...) property disputes, but does not legitimately own land itself. The article discusses and rejects, for deontic and consequentialist reasons, positions that justify collective and state ownership of territory. Some important consequences follow from the argument: First, no actual state has territorial rights, since no actual state wields delegated powers in land. Second, notwithstanding the preceding conclusion, actual states have an obligation to exercise their territorial powers consistently with the respect for private property. (shrink)
Epistemic logic with its possible worlds semantic model is a powerful framework that allows us to represent an agent’s information not only about propositional facts, but also about her own information. Nevertheless, agents represented in this framework are logically omniscient: their information is closed under logical consequence. This property, useful in some applications, is an unrealistic idealisation in some others. Many proposals to solve this problem focus on weakening the properties of the agent’s information, but some authors have argued that (...) solutions of this kind are not completely adequate because they do not look at the heart of the matter: the actions that allow the agent to reach such omniscient state. Recent works have explored how acts of observation, inference, consideration and forgetting affect an agent’s implicit and explicit knowledge; the present work focuses on acts that affect an agent’s implicit and explicit beliefs. It starts by proposing a framework in which these two notions can be represented, and then it looks into their dynamics, first by reviewing the existing notion of belief revision, and then by introducing a rich framework for representing diverse forms of inference that involve both knowledge and beliefs.

Classical epistemic logic describes implicit knowledge of agents about facts and knowledge of other agents based on semantic information. The latter is produced by acts of observation or communication that are described well by dynamic epistemic logics. What these logics do not describe, however, is how significant information is also produced by acts of inference— and key axioms of the system merely postulate "deductive closure". In this paper, we take the view that all information is produced by acts, and hence (...) we also need a dynamic logic of inference steps showing what effort on the part of the agent makes a conclusion explicit knowledge. Strong omniscience properties of agents should be seen not as static idealizations, but as the result of dynamic processes that agents engage in. This raises two questions: (a) how to define suitable information states of agents and matching notions of explicit knowledge, (b) how to define natural processes over these states that generate new explicit knowledge. To this end, we use a static base from the existing awareness literature, extending it into a dynamic system that includes traditional acts of observation, but also adding and dropping formulas from the current ' awareness' set. We give a completeness theorem, and we show how this dynamics updates explicit knowledge. Then we extend our approach to multi-agent scenarios where awareness changes may happen privately. Finally, we mention further directions and related approaches. Our contribution can be seen as a ' dynamification' of existing awareness logics. (shrink)
In public political deliberation, people will err and lie in accordance with definite patterns. Such discourse failure results from behavior that is both instrumentally and epistemically rational. The deliberative practices of a liberal democracy cannot be improved so as to overcome the tendency for rational citizens to believe and say things at odds with reliable propositions of social science. The theory has several corollaries. One is that much contemporary political philosophy can be seen as an unsuccessful attempt to vindicate, on (...) symbolic and moral grounds, the forms that discourse failure take on in public political deliberation. Another is that deliberative practices cannot be rescued even on non-epistemic grounds, such as social peace, impartiality, participation, and equality. To alleviate discourse failure, this book proposes to reduce the scope of majoritarian politics and enlarge markets. (shrink)

Tartışmayı “dış dünyada şahısları bulunan birinci makul” ve “şahıs düzeyinde karşılığı bulunmayan ikinci makul” karşıtlığında değerlendiren İbn Sînâ, görelinin, dış dünyada işaret edilebilir şahısları bulunan kategorik bir araz olduğu görüşündedir ve eş-Şifâ Metafizik’te, benimsediği görüşe karşı öne sürülmüş olan teselsül gerekçeli itirazları ortadan kaldırmayı amaçlayan bir çözüm sunmuştur. Makalede, söz konusu çözümde inşa edilen modelin başkalık anlamı için uygulanabilirliği sınanmış ve bu sınamanın sonucunda başkalığın modelle uyumsuzluğu, bir problem olarak ortaya konmuştur. Problemin (...) kaynağına ilişkin bir incelemede şu tespitler kaydedilmiştir: Kategorik göreli/muzâf ve görelilik/izâfet aynı şeyler değildir. İzâfet, kategorik göreliyi temellendiren ve ona indirgenemeyecek genellikte bir kavramdır, çünkü birlik yükleminin çokluk için geçerli olabilmesi izâfet aracılığıyla gerçekleşmektedir. Başkalık, izâfete içkin ve onunla eş kapsamlı genel bir yüklemdir, dolayısıyla kategorik göreliler dâhil olmak üzere bütün mevcudatın var oluşundaki düzenliliği açıklayan en genel kavramlar sınıfına dâhildir. İbn Sînâ’nın Metafizik’teki çözüm modeli, izâfetin mahiyetlerdeki sonuçlarını açıklamayı amaçladığı için sonuçları önceleyen, kategorileri aşkın izâfet evrelerine, dolayısıyla başkalığa uygulanamamaktadır.

Este artículo se centra en la comparación entre el sultán marroquí Aḥmad al-Manṣūr y el santo de Fez Aḥmad Ibn ‛Abd Allāh Ma‛an. A través de esa comparación, se intenta subrayar el carácter comunicativo de la sacralización del poder, basada en la utilización de determinados recursos retóricos. El análisis de algunos de esos recursos en el caso de Aḥmad al-Mansūr demuestra la dificultad de sacralizar el poder, teniendo en cuenta especialmente el punto de vista de la recepción del discurso.
Este artículo estudia las prácticas visuales destructivas de la iconoclasia. La destrucción es un gesto de emancipación y un acto de inmunización frente a la idolatría religiosa, social y política.

Analizamos los fundamentos de la ofensiva contra el poder de las imágenes en el espacio público. La mutilación visual, la negación, la censura, la prohibición serán prácticas comunes (...) en un espacio intermedio en el que se enreda la libertad de pensamiento. (shrink)

Resumen: Presentamos una recuperación del espíritu humanista en la corriente estética del arte de medios de las ciberculturas. Para mostrar el giro cultural hacia el neorrenacimiento, hacemos un recorrido por los conceptos que fundan el humanismo clásico y que aproximan el arte contemporáneo a la racionalidad tecnológica y mediática. Este artículo revisa el encuentro del hombre consigo mismo, las subjetividades del arte y la expresión en el paradigma de las nuevas tecnologías, la ciencia y la creatividad, así como la renovación (...) de una emergente epistemología visual que desplaza la concepción moderna de obra de arte, de la figura del artista y del lugar del espectador.: We present a recovery of the humanistic spirit in the current aesthetics of the media art in the cybercultures.

This article reviews the meeting of man with himself, the subjectivities of the Art and the expression in the paradigm of new technologies, science and creativity, as well as the renewal of an emerging visual epistemology that moves the modern concept of the work of art, the figure of the artist and the place of the viewer.

As a new type of epistemic logics, the logics of knowing how capture the high-level epistemic reasoning about the knowledge of various plans to achieve certain goals. Existing work on these logics focuses on axiomatizations; this paper makes the first study of their model theoretical properties. It does so by introducing suitable notions of bisimulation for a family of five knowing how logics based on different notions of plans. As an application, we study and compare the expressive power of these (...) logics. (shrink)
