Imperative sentences like Dance! do not seem to represent the world. Recent modal analyses challenge this idea, but its intuitive and historical appeal remain strong. This paper presents three new challenges for a non-representational analysis, showing that the obstacles facing it are even steeper than previously appreciated. I will argue that the only way for the non-representationalist to meet these three challenges is to adopt a dynamic semantics. Such a dynamic semantics is proposed here: imperatives introduce preferences between alternatives. This (...) characterization of meaning focuses on what function a sentence serves in discourse, rather than what that sentence refers to (e.g., a state of the world). By representing the meaning of imperatives, connectives and declaratives in a common dynamic format, the challenges posed for non-representationalism are met. (shrink)

A uniform theory of conditionals is one which compositionally captures the behavior of both indicative and subjunctive conditionals without positing ambiguities. This paper raises new problems for the closest thing to a uniform analysis in the literature (Stalnaker, Philosophia, 5, 269–286 (1975)) and develops a new theory which solves them. I also show that this new analysis provides an improved treatment of three phenomena (the import-export equivalence, reverse Sobel-sequences and disjunctive antecedents). While these results concern central issues in the study (...) of conditionals, broader themes in the philosophy of language and formal semantics are also engaged here. This new analysis exploits a dynamic conception of meaning where the meaning of a symbol is its potential to change an agent’s mental state (or the state of a conversation) rather than being the symbol’s content (e.g. the proposition it expresses). The analysis of conditionals is also built on the idea that the contrast between subjunctive and indicative conditionals parallels a contrast between revising and consistently extending some body of information.

This paper proposes a semantics for free choice permission that explains both the non-classical behavior of modals and disjunction in sentences used to grant permission, and their classical behavior under negation. It also explains why permissions can expire when new information comes in and why free choice arises even when modals scope under disjunction. On the proposed approach, deontic modals update preference orderings, and connectives operate on these updates rather than propositions. The success of this approach stems from its capacity (...) to capture the difference between expressing the preferences that give rise to permissions and conveying propositions about those preferences.

No existing conditional semantics captures the dual role of 'if' in embedded interrogatives — 'X wonders if p' — and conditionals. This paper presses the importance and extent of this challenge, linking it to cross-linguistic patterns and other phenomena involving conditionals. Among these other phenomena are conditionals with multiple 'if'-clauses in the antecedent — 'if p and if q, then r' — and relevance conditionals — 'if you are hungry, there is food in the cupboard'. Both phenomena are shown to (...) be problematic for existing analyses. Surprisingly, the decomposition of conditionals needed to capture the link with interrogatives provides a new analysis that captures all three phenomena. The model-theoretic semantics offered here relies on a dynamic conception of meaning and compositionality, a feature discussed throughout. (shrink)

Utterances of natural language sentences can be used to communicate not just contents, but also forces. This paper examines this topic from a cross-linguistic perspective on sentential mood. Recent work in this area focuses on conversational dynamics: the three sentence types can be associated with distinctive kinds of conversational effects called sentential forces, modeled as three kinds of updates to the discourse context. This paper has two main goals. First, it provides two arguments, on empirical and methodological grounds, for treating (...) sentential force as part of a compositional dynamic semantics, rather than a dynamic pragmatics. Second, it formulates a minimal dynamic semantic analysis that covers the data at the heart of these arguments, incorporating existing analyses of the three major moods, evidentials and conjunction. A further aim of the paper is to sharpen the distinction between sentential force and utterance force, and discuss its implications. (shrink)

There is a big difference between saying Maya is singing, Is Maya singing? and Sing Maya! This paper examines and criticizes two attempts to rigorously explain this difference: Searle’s speech act theory and the truth-conditional reductionism advocated by Davidson and Lewis. On the speech act analysis, each utterance contains a marker which says what kind of speech act the utterance counts as performing. The truth-conditional reductionists try to reanalyze the non-declaratives (Is Maya singing? and Sing Maya!) as complex declarative forms. (...) The former analysis fails to recognize the indirect relationship between sentence (or clause) type and utterance force. The latter analysis fails to recognize the distinctive and thoroughly compositional contribution that the imperative, interrogative and declarative mood make to sentences containing them. (shrink)

In fourteen scholarly yet delightfully readable essays, Ober solves some ancient mysteries and reveals the secret kinks and passions of famous and obscure historical figures.

The ArgumentMany of the epistemological issues that occupied natural philosophers of the seventeenth century were expressed visually in title-page engravings. One of those issues concerned the relative status to be accorded to evidence of the senses, as compared to knowledge gained by faith or reason. In title-page illustrations, the various arguments were often waged by a series of light metaphors: the Light of Reason, the Light of Nature, and the Lights of Sense, Scripture, and Grace. When such illustrations are examined (...) with the authors' theological views in mind, it becomes apparent that in the first half of the seventeenth century, Catholic authors favored the Light of Reason as a source of truth, while Protestant authors favored the Light of Nature. Since by the end of the century it was widely accepted by scientists of all religious persuasions that certain knowledge must be grounded in sense evidence and the direct study of nature, one might argue that in this instance Protestantism was responsible for nurturing an important development of the Scientific Revolution. However, the skewed nature of the sample and the large number of counterexamples available mitigate against taking this offshoot of the Merton thesis too seriously. (shrink)

The rapid pace of technological development often outstrips the ability of legislators and regulators to establish proper guardrails on emerging technologies. A solution is for those who develop, deploy, and use these technologies to develop themselves as moral agents—i.e., as agents capable of steering the course of emerging technologies in a direction that will benefit humanity. However, there is a dearth of literature discussing how to foster moral agency in computer science courses, and little if any research on the effectiveness (...) of such courses in computer science. This paper addresses this gap by providing an overview of an undergraduate course on technology ethics. It then shares and discusses a subset of data collected from a mixed-methods study using a pre-post design that sought to examine the course’s effectiveness in developing students’ moral, intellectual, and civic virtues, as well as related dispositions.

In this paper, I examine various popular notions concerning the ethics of investing. I first consider and reject the absolutist view that it is always wrong to invest in evil companies and the view that what makes investments in evil companies morally objectionable is the fact that by making such investments, investors are taking steps to benefit from the wrongdoing of others. I then defend the view that what makes certain investments morally objectionable is the fact that by making such (...) investments, investors enable others to do wrong. According to this view, when weighing the purchase of a certain company's stock, investors should ask themselves the following question: Would this sort of investment, if made by many people, enable others to do wrong? If the answer to this question is yes, and if an investor nevertheless makes the investment in question, he can justifiably be accused of moral wrongdoing. (shrink)

Biodiversity and genetic resources have become the focal point of major national and international biological and political debates regarding control, ownership, access, and erosion of critical resources. While these issues are key to environmental sustainability and food security, biodiversity and genetic resources must be seen in the broader context of their inextricable relationship to cultural diversity and to humans' view of nature. Nature is assumed to be constituted socially through a wide variety of human processes described collectively as culture. Three (...) significant cultural factors, technology, science, and capitalism, are largely responsible for the secularization and homogenization of food and agriculture and the remaking of nature. These processes and forces may simultaneously and unwittingly create the problems of declines in biodiversity, cultural diversity, and food equity. Indeed, it may well be that the only way to conserve cultural biodiversity in the field is to conserve cultural diversity among peoples. This reunification of biodiversity and cultural diversity and food and agriculture will require new paradigms and institutional mechanisms that allow us to show our care for each other through our reverence for nature.

This article updates the author’s 1982 argument that lutetium and lawrencium, rather than lanthanum and actinium, should be assigned to the d-block as the heavier analogs of scandium and yttrium, whereas lanthanum and actinium should be considered as the first members of the f-block with irregular configurations. This update is embedded within a detailed analysis of Lavelle’s abortive 2008 attempt to discredit this suggestion.

Mr P. F. Strawson's book Individuals is subtitled An Essay in Descriptive Metaphysics. ‘Descriptive metaphysics’, he writes, ‘is content to describe the actual structure of our thought about the world’, whereas ‘revisionary metaphysics is concerned to produce a better structure’; it is distinguished from logical or conceptual analysis in scope and generality, rather than in fundamental intention. The book is divided into two parts; in Strawson's words, ‘the first part aims at establishing the central position which material bodies and persons (...) occupy among particulars in general. … In the second part of the book the aim is to establish and explain the connexion between the idea of a particular in general and that of an object of reference or logical subject.’.
