This paper presents our work on textual inference and situates it within the context of the larger goals of machine reading. The textual inference task is to determine if the meaning of one text can be inferred from the meaning of another and from background knowledge. Our system generates semantic graphs as a representation of the meaning of a text. This paper presents new results for aligning pairs of semantic graphs, and proposes the application of natural logic to derive inference (...) decisions from those aligned pairs. We consider this work as first steps toward a system able to demonstrate broad-coverage text understanding and learning abilities. (shrink)

Civil libertarians characterize prostitution as a "victimless crime," and argue that it ought to be legalized. Feminist critics counter that prostitution is not victimless, since it harms the people who do it. Civil libertarians respond that most women freely choose to do this work, and that it is paternalistic for the government to limit a person's liberty for her own good. In this book Peter de Marneffe argues that although most prostitution is voluntary, paternalistic prostitution laws in some form (...) are nonetheless morally justifiable. If prostitution is commonly harmful in the way that feminist critics maintain, then this argument for prostitution laws is not objectionably moralistic and some prostitution laws violate no one's rights. Paternalistic prostitution laws in some form are therefore consistent with the fundamental principles of contemporary liberalism. (shrink)

Scanlon's distinction between well-being and other personal values cannot be made out clearly if well-being is understood, as it commonly is, to consist in whatever is intrinsically good for a person. Two other accounts of well-being, however, might be able to explain this distinction. One is a version of the rational care view proposed by Stephen Darwall; another is a rational sympathy view suggested by some of Brad Hooker's work.

Hart argues persuasively that majority disapproval cannot justify the government in prohibiting a form of sexual conduct, but he does not address the possibility that the intrinsic badness of a sex act might justify the government in prohibiting it. This article explains within a contractualist framework why the intrinsic badness of a sex act cannot justify the restriction of any important sexual freedom.

There is an important moral difference between laws that criminalize drugs and prostitution and laws that make them illegal in other ways: criminalization violates our moral rights in a way that nonlegalization does not. Criminalization is defined as follows. Drugs are criminalized when there are criminal penalties for using or possessing small quantities of drugs. Prostitution is criminalized when there are criminal penalties for selling sex. Legalization is defined as follows. Drugs are legalized when there are no criminal penalties for (...) manufacturing, selling and possessing large quantities of drugs. Prostitution is legalized when there are no criminal penalties for owning or operating a brothel or escort service, no criminal penalties for working as a paid agent for sex work, and no criminal penalties for paying someone for sex who is above the age of legal employment and sexual consent. The criminalization of drugs and prostitution violate the right of self-sovereignty in depriving individuals of important forms of control over their own minds and bodies, but nonlegalization does not violate this right. It is therefore consistent, as a matter of principle, to advocate decriminalization but to oppose legalization. (shrink)

This article argues that attitudinal hedonism is false as atheory of what is intrinsically good for us because it impliesthat nothing is intrinsically good for someone who does nothave the psychological capacity for the propositional attitudeof enjoyment even if he has other important mental capacitiesthat humans have.

In the United States today, the use or possession of many drugs is a criminal offense. Can these criminal laws be justified? What are the best reasons to punish or not to punish drug users? These are the fundamental issues debated in this book by two prominent philosophers of law. Douglas Husak argues in favor of drug decriminalization, by clarifying the meaning of crucial terms, such as legalize, decriminalize, and drugs; and by identifying the standards by which alternative drug policies (...) should be assessed. He critically examines the reasons typically offered in favor of our current approach and explains why decriminalization is preferable. Peter de Marneffe argues against drug legalization, demonstrating why drug prohibition, especially the prohibition of heroin, is necessary to protect young people from self-destructive drug use. If the empirical assumptions of this argument are sound, he reasons, drug prohibition is perfectly compatible with our rights to liberty. (shrink)

This article argues that attitudinal hedonism is false as a theory of what is intrinsically good for us because it implies that nothing is intrinsically good for someone who does not have the psychological capacity for the propositional attitude of enjoyment even if he has other important mental capacities that humans have.

Rigorous proof is supposed to guarantee that the premises invoked imply the conclusion reached, and the problem of rigor may be described as that of bringing together the perspectives of formal logic and mathematical practice on how this is to be achieved. This problem has recently raised a lot of discussion among philosophers of mathematics. We survey some possible solutions and argue that failure to understand its terms properly has led to misunderstandings in the literature.

A kind of “ruthless reductionism” characterized the experimental practices of the first two decades of molecular and cellular cognition. More recently, new research tools have expanded experimental practices in this field, enabling researchers to image and manipulate individual molecular mechanisms in behaving organisms with an unprecedented temporal, sub-cellular, cellular, and even circuit-wide specificity. These tools dramatically expand the range and reach of experiments in MCC, and in doing so they may help us transcend the worn-out and counterproductive debates about “reductionism” (...) and “emergence” that divide neuroscientists and philosophers alike. We describe examples of these new tools and illustrate their practical power by presenting an exemplary recent case of MCC research using them. From these tools and results, we provide an initial sketch of a new image of the behaving organism in its full causal-interactive complexity, with its molecules, cells, and circuits combined within the single system that it is. This new image stands in opposition to the traditional “levels” image of the behaving organism, and even the initial sketch we provide of it here offers hope for avoiding the dreary metaphysical debates about “emergence” and “downward causation,” and even the reduction vs. anti-reduction dispute, all dependent upon the familiar “levels” image.

We describe an approach to textual inference that improves alignments at both the typed dependency level and at a deeper semantic level. We present a machine learning approach to alignment scoring, a stochastic search procedure, and a new tool that finds deeper semantic alignments, allowing rapid development of semantic features over the aligned graphs. Further, we describe a complementary semantic component based on natural logic, which shows an added gain of 3.13% accuracy on the RTE3 test set.

Several authors have argued that socially significant places such as countries, cities and establishments are immaterial objects, despite their being spatially located. In contrast, we aim to defend a reductive materialist view of such entities, which identifies them with their physical territories or premises. Accordingly, these are all material objects; typically, aggregates of land and infrastructure. Admittedly, our terms for these entities may also sometimes be used to denote their associated groups of people. But as long as countries, cities and (...) establishments are understood as places, we submit, they are all material objects: the physical territories or premises of their associated groups.

In this paper we publish three fragments of a cuneiform tablet that, when complete, contained the dates and zodiacal positions of Saturn’s synodic phenomena for roughly 60 years. The text is unique in containing comparisons of computed data with observations. Through an analysis of the preserved data we propose that the dates and positions were computed by an otherwise unknown two-zone System A-type scheme and show that the computed data in the tablet can be dated to the fourth century BC. (...) This early date and the comparisons with observations suggest that the text was produced during the period of active development of the planetary systems. (shrink)

Charlotte Witt has argued that gender is essential to women and men, in a way that unifies them as social individuals but precludes each of them from being identified with the corresponding person or human organism. We respond to Witt’s modal and normative arguments for this view, and we argue that they fail to support anything stronger than a moderate version of kind essentialism, which generally allows women and men to be identified with people. We finish by pointing out that (...) several of Witt’s central claims about gender roles and gender norms could be endorsed while rejecting her ontology of coincident individuals. (shrink)

Epistemic value is a kind of value possessed by knowledge, and perhaps other epistemic goods such as justification and understanding. The problem of explaining the value of knowledge is perennial in philosophy, going back at least as far as Plato’s Meno. One formulation of the problem is to explain why and in what sense knowledge is valuable. Another version of the problem is to explain why and in what sense knowledge is more valuable than mere true belief or opinion. This (...) article looks at various formulations of the value problem and various accounts of the value of knowledge in ancient and modern philosophy. The article then considers some contemporary discussions of the value problem, including the charge that reliabilist accounts cannot account for the value of knowledge over mere true belief. Various virtue-theoretic accounts of epistemic value are discussed as possible improvements over process reliabilism, and the epistemic value of understanding (as compared to knowledge) is considered.

Other people in our culture actively transform our behavioral dispositions and mental states by shaping them in various ways. In the following, we highlight three points which Veissière et al. may consider in leveraging their account to illuminate the dynamics by which this occurs, and in particular, to shed light on how social cognition supports, and is supported by, enculturation.

Written by an emigrant French aristocrat turned farmer, the Letters from an American Farmer posed the famous question `What, then, is the American, this new man?', as the new nation took shape before the eyes of the world. Addressing some of American literature's most pressing concerns and issues of identity, the Letters celebrates personal determination, freedom from institutional oppression and the largeness and fertility of the land, and also raises darker and more symbolic elements, particularly slavery. This is the only (...) critical edition available of what is regarded as the first ever work of American literature. (shrink)
