The Good Samaritan and the Hygienic Cook: A Cautionary Tale About Linguistic Data
When developing formal theories of the meaning of language, it is appropriate to consider how apparent paradoxes and conundrums of language are best resolved. But if we base our analysis on a small sample of data then we may fail to take into account the influence of other aspects of meaning on our intuitions. Here we consider the so-called Good Samaritan Paradox (Prior, 1958), where we wish to avoid any implication that there is an obligation to rob someone from "You must help a robbed man". We argue that before settling on a formal analysis of such sentences, we should consider examples of the same form, but with intuitively ?different entailments ? such as "You must use a clean knife" ? and also actively seek other examples that exhibit similar contrasts in meaning, even if they do not exemplify the phenomena that is under investigation. This can refine our intuitions and help us to attribute aspects of interpretation to the various facets of meaning
The Alienation Objection to Consequentialism
An ethical theory is alienating if accepting the theory inhibits the agent from fitting participation in some normative ideal, such as some ideal of integrity, friendship, or community. Many normative ideals involve non-consequentialist behavior of some form or another. If such ideals are normatively authoritative, they constitute counterexamples to consequentialism unless their authority can be explained or explained away. We address a range of attempts to avoid such counterexamples and argue that consequentialism cannot by itself account for the normative authority of all plausible such ideals. At best, consequentialism can find a more modest place in an ethical theory that includes non-consequentialist principles with their own normative authority
Designing Normative Theories for Ethical and Legal Reasoning: LogiKEy Framework, Methodology, and Tool Support
A framework and methodology---termed LogiKEy---for the design and engineering
of ethical reasoners, normative theories and deontic logics is presented. The
overall motivation is the development of suitable means for the control and
governance of intelligent autonomous systems. LogiKEy's unifying formal
framework is based on semantical embeddings of deontic logics, logic
combinations and ethico-legal domain theories in expressive classic
higher-order logic (HOL). This meta-logical approach enables the provision of
powerful tool support in LogiKEy: off-the-shelf theorem provers and model
finders for HOL are assisting the LogiKEy designer of ethical intelligent
agents to flexibly experiment with underlying logics and their combinations,
with ethico-legal domain theories, and with concrete examples---all at the same
time. Continuous improvements of these off-the-shelf provers, without further
ado, leverage the reasoning performance in LogiKEy. Case studies, in which the
LogiKEy framework and methodology has been applied and tested, give evidence
that HOL's undecidability often does not hinder efficient experimentation.Comment: 50 pages; 10 figure
Ethics and the Perfect Moral Law
Summary
This paper examines contemporary virtue ethics and the claim that Christian ethics is a virtue ethic. Three central theses are identified as being central to virtue ethics: a priority thesis, a perfectionist thesis and a communitarian thesis. It is argued that defences of the priority thesis—it best addresses the moral crisis in our society, it does justice to historical consciousness and it remedies the incompleteness in deontic ethics—are unconvincing. It is argued that virtue and moral perfection are best understood in terms of psychologically appropriate dispositions to act in accordance with moral principles. It is further argued that the communitarian thesis raises relativist difficulties and fails to do justice to the universal elements of morality. Each of these arguments is developed philosophically and the implications for Christian ethics are explored. In light of the theory of virtue sketched in the paper it is concluded that the independence thesis, upon which virtue ethics rests, is untenable and that an examination of the structure of the universal moral principles underlying the Christian faith remains the proper subject matter for Christian ethics
Metanormative Theory and the Meaning of Deontic Modals
Philosophical debate about the meaning of normative terms has long been pulled in two directions by the apparently competing ideas: (i) ‘ought’s do not describe what is actually the case but rather prescribe possible action, thought, or feeling, (ii) all declarative sentences deserve the same general semantic treatment, e.g. in terms of compositionally specified truth conditions. In this paper, I pursue resolution of this tension by rehearsing the case for a relatively standard truth-conditionalist semantics for ‘ought’ conceived as a necessity modal and proposing a revision to it motivated by the distinctively prescriptive character of some deontic modals. In my view, this puts pressure on a popular conception of one of the core debates of metanormative theory between realists and antirealists. To make good on this claim, I go on to explore two very general ways we might interpret the results of compositional semantics—“representationalism” and “inferentialism”—in order to argue that, contrary to what is generally assumed, both can capture the special prescriptivity of ‘ought’ and both can countenance compositionally specified and informative truth-conditions for ought-sentences. Hence, my main thesis is that the deciding factor between them should not be which of ideas (i) and (ii) we are more impressed by but rather what we think of the relative merits of how representationalism and inferentialism respect these ideas. I’m inclined to favor an antirealist form of inferentialism, but the task I’ve set myself here is mainly to articulate the view in the context of metanormative theory and the semantics of deontic modals rather than try to defend it fully. To this purpose, towards the end I also briefly compare and contrast inferentialism with a third “ideationalist” metasemantic view, which may be an attractive home for some sophisticated versions of metanormative expressivism. Depending on how expressivism is worked out, it may be completely compatible with and so perhaps usefully combined with inferentialism or it may offer a competing way to respect ideas (i) and (ii)
Contextualism and Knowledge Norms
I provide an opinionated overview of the literature on the relationship of contextualism to knowledge norms for action, assertion, and belief. I point out that contextualists about ‘knows’ are precluded from accepting the simplest versions of knowledge norms; they must, if they are to accept knowledge norms at all, accept “relativized” versions of them. I survey arguments from knowledge norms both for and against contextualism, tentatively concluding that commitment to knowledge norms does not conclusively win the day either for contextualism or for its rivals. But I also suggest that an antecedent commitment to contextualism about normative terms may provide grounds for suspicion about knowledge norms, and a debunking explanation of some of the data offered in favor of such norms
Two Ways to Want?
I present unexplored and unaccounted for uses of 'wants'. I call them advisory uses, on which information inaccessible to the desirer herself helps determine what she wants. I show that extant theories by Stalnaker, Heim, and Levinson fail to predict these uses. They also fail to predict true indicative conditionals with 'wants' in the consequent. These problems are related: intuitively valid reasoning with modus ponens on the basis of the conditionals in question results in unembedded advisory uses. I consider two fixes, and end up endorsing a relativist semantics, according to which desire attributions express information-neutral
propositions. On this view, 'wants' functions as a precisification of 'ought', which exhibits similar unembedded and compositional behavior. I conclude by sketching a pragmatic account of the purpose of desire attributions that explains why it made sense for them to evolve in
this way

Stance-taking in Spanish-speaking Preschoolers' Argumentative Interaction
The aim of this study is to determine what linguistic resources are used for stance-taking in confrontational interactions. For this purpose, we analyze 70 argumentative sequences in spontaneous peer conversations during play situations of 4 dyads (2 mid and 2 low socio-economic status backgrounds) of 4 to 7-year-old Argentinian children. Stance-taking relies on the use of evaluative language, understood as the markers of speaker's attitude (reference to internal states such as attribute, cognition, emotion, intention, and reported speech, [Shiro, 2003]); and the use of evidential markers, understood as speaker's reference to the status of the information in the utterance (causality, concession, capacity, deontic and epistemic modality, and inference, [Shiro, 2007]), including markers of politeness which serve to mitigate (or intensify) the confrontation (Watts, 2003). Our findings describe the evaluative resources used for stance-taking strategies produced by children at this early age in confrontational interactions with their peers.Fil: Shiro, Martha.
