Abstract: A time machine mysteriously appeared one day in ancient Athens. Curious about the future of philosophical dialogue, Socrates entered the device and traveled to the 21st Century. He spent several months in the United Kingdom and United States discussing metaethics before returning to Athens, now a devoted and formidable quasi-realist moral genderexpressivist.

Publisher's Note: Only human beings have a rich conceptual repertoire with concepts like tort, entropy, Abelian group, mannerism, icon and deconstruction. How have humans constructed these concepts? And once they have been constructed by adults, how do children acquire them? While primarily focusing on the second question, in The Origin of Concepts , Susan Carey shows that the answers to both overlap substantially.

Carey begins by characterizing the innate starting point for conceptual development, namely systems of core cognition. Representations of core cognition are the output of dedicated input analyzers, as with perceptual representations, but these core representations differ from perceptual representations in having more abstract contents and richer functional roles. Carey argues that the key to understanding cognitive development lies in recognizing conceptual discontinuities in which new representational systems emerge that have more expressive power than core cognition and are also incommensurate with core cognition and other earlier representational systems. Finally, Carey fleshes out Quinian bootstrapping, a learning mechanism that has been repeatedly sketched in the literature on the history and philosophy of science. She demonstrates that Quinian bootstrapping is a major mechanism in the construction of new representational resources over the course of childrens cognitive development.

Carey shows how developmental cognitive science resolves aspects of long-standing philosophical debates about the existence, nature, content, and format of innate knowledge. She also shows that understanding the processes of conceptual development in children illuminates the historical process by which concepts are constructed, and transforms the way we think about philosophical problems about the nature of concepts and the relations between language and thought.

Publisher's Note: Norms in the Wild takes a unique look at social norms, answering questions about diagnosis (how can we tell that a shared practice is a social norm?), measurement (how do we measure expectations and preferences?), and change (which tools can we adopt to effect norm change?). The theories developed in the book are brought to life by examining real-life cases of norm creation and abandonment, the rationale behind policy interventions, and how change can be spearheaded by various types of trendsetters, be they individuals, groups, or the media. By exploring how a range of problems, from poor sanitation to child marriage, can be addressed, the book shows how social norms can have a causal impact on collective behavior, and which interventions may succeed in creating new norms or abandoning harmful ones. In laying the theoretical groundwork for implementing social changes in a contextually sensitive and empirically based way, it also diagnoses why some less culturally attuned attempts to eliminate negative practices have failed.

Publisher's Note: This book is a defense of political liberalism as a feminist liberalism. The first half of the book develops and defends a novel interpretation of political liberalism. It is argued that political liberals should accept a restrictive account of public reason and that political liberals' account of public justification is superior to the leading alternative, the convergence account of public justification. The view is defended from the charge that such a restrictive account of public reason will unduly threaten or undermine the integrity of some religiously oriented citizens and an account of when political liberals can recognize exemptions, including religious exemptions, from generally applicable laws is offered. In the second half of the book, it is argued that political liberalism's core commitments restrict all reasonable conceptions of justice to those that secure genuine, substantive equality for women and other marginalized groups. Here it is demonstrated how public reason arguments can be used to support law and policy needed to address historical sites of women's subordination in order to advance equality; prostitution, the gendered division of labor and marriage, in particular, are considered.

Abstract: It is widely held that moral obligations to non-human beings do not involve considerations of justice. For such a view, nonhuman interests are always prone to be trumped by human interests. Rawlsian contractarianism comprises an example of such a view. Through analysis of such theories, this essay highlights the problem of reconciling the claim that humans have obligations to non-humans with the claim that our treatment of the latter is not a matter of justice. We argue that if it is granted that the basic interests of non-human beings sometimes count for more than the peripheral interests of humans, then our understandings of obligation and of justice must be aligned, so that what we say about obligation is not countered by assumptions about the invariable priority of humans in matters of justice. We further consider whether such a conclusion can be endorsed by those who adopt certain alternative theories to contractarianism. We conclude that adherents of a range of theories including sentientism and biocentrism must accept that human interests can sometimes be superseded by animal interests, and that this applies not least in matters of justice.

Abstract: Humanists argue for assigning the highest moral status to all humans over any non-humans directly or indirectly on the basis of uniquely superior human cognitive abilities. They may also claim that humanism is the strongest position from which to combat racism, sexism, and other forms of within-species discrimination. I argue that changing conceptual foundations in comparative research and discoveries of advanced cognition in many non-human species reveal humanism’s psychological speciesism and its similarity with common justifications of within-species discrimination.

Abstract: "[T]he sceptical argument that Kripke attributes to Wittgenstein, and even the 'sceptical solution', are of considerable importance regardless of whether they are clearly Wittgenstein's. The naturalistically inclined philosopher, who rejects Brentano's irreducibility and yet holds intentionality to be an objective feature of our thoughts, owes a solution to the Kripke-Wittgenstein paradox." The challenge is a welcome one. Although I will argue that the Kripke-Wittgenstein paradox is not a problem for naturalists only, I will propose a naturalist solution to it. (Should the Kripke-Wittgenstein paradox prove to be soluble from a naturalist standpoint but intractable from other standpoints, that would, I suppose, constitute an argument for naturalism.) Then I will show that the paradox and its solution have an important consequence for the theories of meaning and truth. The Kripke-Wittgenstein arguments which pose the paradox also put in question Dummett's and Putnam's view of language understanding. From this view it follows that truth rules must be "verificationist rules" that assign assertability conditions to sentences, rather than "realist rules" that assign correspondence truth conditions. The proposed solution to the paradox suggests another view of language understanding, according to which a speaker can express, through his language practice, a grasp of correspondence truth rules.

Abstract: Although the practices of animal experimentation and intensive rearing involve a considerable amount of animal suffering they continue to be supported. Why is the suffering of animals in these practices so often accepted? This paper will explore some of the reasons given in support of the use of animals for such practices. In particular I will focus on contractarianism as one of the many positions that argues that morally relevant differences between species justify animal experimentation and factory farming. These differences include rationality and moral agency. On this position non-humans are excluded from direct moral concern on the basis that they lack such qualities. I will argue that in order for contractarianism to be coherent it necessarily has to include non-humans in the contract. This has implications for the application of contractarianism to the ethics of factory farming and animal experimentation.

Abstract:

Abstract: The idea that language is necessary for thought and emotion is a dominant one in philosophy. Animals have taken the brunt of this idea, since it is widely held that language is exclusively human. Michael Leahy makes a case against the moral standing of factory-farmed animals based on such ideas. His approach is Wittgensteinian: understanding is a thought process that requires language, which animals do not possess. But he goes further than this and argues that certain factory farming methods do not cause certain sufferings to the animals used, since animals lack full awareness of their circumstances. In particular he argues that animals do not experience certain sufferings at the slaughterhouse since, lacking language, they are unaware of their fate . Through an analysis of Leahy’s claims this paper aims to explore and challenge both the idea that thought and emotion require language and that only humans possess language
