Any adequate semantics of generic sentences (e.g., “Philosophers evaluate arguments”) must accommodate both what we call the positive data and the negative data. The positive data consists of observations about what felicitous interpretations of generic sentences are available. Conversely, the negative data consists of observations about which interpretations of generic sentences are unavailable. Nguyen argues that only his pragmatic neo-Gricean account and Sterken’s indexical account can accommodate the positive data. Lee and Nguyen have advanced the debate by arguing that the (...) negative data is a problem for both Nguyen’s and Sterken’s accounts; these two accounts seem to incorrectly predict that generics have felicitous interpretations that they, in fact, fail to have. In this paper, we advance this debate—and, more generally, the task of developing an adequate formal semantics of generics—by arguing that a neglected class of theories are compatible with both the positive data and the negative data. Specifically, we argue that treating the generic operator GEN as a relative gradable expression with a positive, upper- and lower- bounded scale helps accommodate the positive data and the negative data. While developing this view, we show how several previously developed semantics of generics may systematically accommodate both sets of data. One broad contribution of this paper is to show that, while they generate important desiderata, the positive and negative data cannot determine a unique semantics for generics. A further contribution of this paper is to highlight previously unnoted ways in which degree semantics may inform semantic theories of generic meaning. (shrink)

Generic statements (‘Tigers have stripes’) are pervasive and early-emerging modes of generalization with a distinctive linguistic profile. Previous experimental work found that generics display a unique asymmetry between their acceptance conditions and the implications that are typically drawn from them. This paper presents evidence against the hypothesis that only generics display an asymmetry. Correcting for limitations of previous designs, we found a generalized asymmetry effect across generics, various kinds of explicitly quantified statements (‘most’, ‘some’, ‘typically’, ‘usually’), and variations in types (...) of predicated properties (striking vs. neutral). We discuss implications of these results for our understanding of the source of asymmetry effects and whether and in which ways these effects might introduce biased beliefs into social networks.

Generics are sentences such as Birds fly, which express generalizations. They are prevalent in speech, and as far as is known, no human language lacks generics. Yet, it is very far from clear what they mean. After all, not all birds fly—penguins don’t! -/- There are two general views about the meaning of generics in the literature, and each view encompasses many specific theories. According to the inductivist view, a generic states that a sufficient number of individuals satisfy a certain (...) property—in the example above, it says that sufficiently many birds fly. This view faces the complicated problem of spelling out exactly how many is “sufficiently many” in a way that correctly captures the intuitive truth conditions of generics. -/- An alternative, the rules and regulations view, despairs from this project and proposes instead that generics directly express rules in the world. Rules are taken to be abstract objects, which are not related to the properties of specific individuals. This view faces the difficult problem of explaining how people come to know of such rules when judging the truth of falsity of generics, and accounting for the strong intuition that a sentence such as Birds fly talks about birds, not abstract objects. -/- What seems to be beyond dispute is that generics, even if they do not express rules, are lawlike: they state non-accidental generalizations. Many scholars have taken this fact to indicate that generics are parametric on possible worlds: they refer to worlds other than the actual world. This, again, raises the problem of how people come to know about what happens in these other worlds. However, a rigorous application of standard tests for intensionality shows that generics are not, in fact, parametric on possible worlds, but only on time. This unusual property may explain much of the mystery surrounding generics. -/- Another mysterious property of generics is that although there is no language without them, there is no linguistic construction that is devoted to the expression of genericity. Rather, generics can be expressed in a variety of ways, each of which can also express nongenerics. Yet, each manifestation of generics differs subtly (or sometimes not so subtly) in its meaning from the others. -/- Even when these and other puzzles of genericity are solved, one mystery would remain: Why are generics, which are so easy to produce and understand in conversation, so difficult to analyze?

In his _Between Logic and the World_, in the course of presenting his theory of generics, Nickel (Between logic and the world, Oxford University Press, 2016) argues for a theory of characteristicness, or “genericity”, which states that a property is characteristic for a kind if and only if its presence among the members of that kind is explicable by some explanatory domain that recognizes the existence of that kind in the course of engaging the explanatory strategies made available by that (...) explanatory domain. I argue that this notion of genericity is too narrow, excluding properties characteristic for kinds that go unrecognized in such explanatory domains. In particular, Nickel’s theory excludes some characteristic properties of anthropic kinds, such as lilies and cedars, members of which have properties that may be similarly exploited in various human practices despite having divergent geneses. I argue for a generalization of Nickel’s view of genericity where explicability of presence is only one sort of genericity, with others, such as practicability, being possible too. (shrink)

The ‘limits of markets’ debate broadly concerns the question of when it is (im)permissible to have a market in some good. Markets can be of tremendous benefit to society, but many have felt that certain goods should not be for sale (e.g., sex, kidneys, bombs). Their sale is argued to be corrupting, exploitative, or to express a form of disrespect. InMarkets without Limits, Jason Brennan and Peter Jaworski have recently argued to the contrary: For any good, as long as it (...) is permissible to give it for free, then it is permissible to give it for money. Their thesis has led to a number of engaging objections, and I leverage recent work on the nature of feasibility within political philosophy to offer a new challenge.I argue that feasibility offers a constraint on which markets can be permissibly implemented. Though it may be possible to create a morally acceptable version of an otherwise repugnant market, some of these markets may be infeasible, and so we are not permitted to implement them. After laying out this challenge, I consider several replies. They concern the relevance of feasibility, and whether any markets really are infeasible. This provides an opportunity to explore the dangers of pursuing the infeasible and with markets generally. I conclude by considering what might lead us to pursue these markets despite their infeasibility, or how knowledge of infeasibility may prove useful regardless. (shrink)

As is well known, research on generics is represented by three approaches: majority- based (Cohen 1996, 1999, 2004), normalcy-based (Nickel 2006; 2009; 2010a, b; 2013; 2016; 2018), and cognition-based (Leslie 2007a, b; 2008; 2013; 2017) approaches. Two recent approaches proposed by van Rooij and Schulz (2020) and Tessler and Goodman (2019) are more elaborated theories on generics, although neither of these approaches nor the three representative theories can fully account for various generics data, as argued by Yoon (2021). On the (...) other hand, Nguyen (2020) proposes another theory of generics, the so-called ‘radical’ theory, which argues that the generic operator has no semantic content, and that the various quantificational interpretations of bare plural generics are determined contextually. In this context, the main purpose of this paper is to provide a critical review of some recently published analyses, including Nguyen’s theory, and to analyze non-conventionalized generics. While conventionalized or conceptualized generics have received much attention from researchers, non- conventionalized generics have not been studied as extensively. It will be argued that Nguyen’s theory simply transfers the burden onto pragmatics, and that non- conventionalized as well as conventionalized generics tend to be interpreted based on people’s perceptions of their exceptions, in line with Yoon (2021). This position will be supported by experimental results. (shrink)

InSuppose and Tell, Williamson makes a new and original attempt to defend the material conditional account of indicative conditionals. His overarching argument is that this account offers the best explanation of the data concerning how people evaluate and use such conditionals. We argue that Williamson overlooks several important alternative explanations, some of which appear to explain the relevant data at least as well as, or even better than, the material conditional account does. Along the way, we also show that Williamson (...) errs at important junctures about what exactly the relevant data are. (shrink)

According to Adams, the acceptability of an indicative conditional goes with the conditional probability of the consequent given the antecedent. However, some conditionals seem to be inappropriate, although their corresponding conditional probability is high. These are cases with a missing link between antecedent and consequent. Other conditionals are appropriate even though the conditional probability is low. Finally, we have the so-called biscuit conditionals. In this paper we will generalize analyses of Douven and others to account for the appropriateness of conditionals (...) in terms of evidential support. Our generalization involves making use of Value, or intensity. We will show how this generalization helps to account for biscuit conditionals and conditional threats and promises. Finally, a link is established between this analysis of conditionals and an analysis of generic sentences. (shrink)

Many generic sentences express stable inductive generalizations. Stable inductive generalizations are typically true for a causal reason. In this paper we investigate to what extent this is also the case for the generalizations expressed by generic sentences. More in particular, we discuss the possibility that many generic sentences of the form ‘ks have feature e’ are true because kind k have the causal power to ‘produce’ feature e. We will argue that such an analysis is quite close to a probabilistic (...) based analysis of generic sentences according to which ‘relatively many’ ks have feature e, and that, in fact, this latter type of analysis can be ‘grounded’ in terms of causal powers. We will argue, moreover, that the causal power analysis is sometimes preferred to a correlation-based analysis, because it takes the causal structure that gives rise to the probabilistic data into account.

A single significant instance may support general conclusions, with possible exceptions being tolerated. This is the case in practical human reasoning (e.g. moral and legal normativity: general rules tolerating exceptions), in theoretical human reasoning engaging with external reality (e.g. empirical and social sciences: the use of case studies and model organisms) and in abstract domains (possibly mind-unrelated, e.g. pure mathematics: the use of arbitrary objects). While this has been recognized in modern times, such a process is not captured by current (...) models of supporting general conclusions. This paper articulates the thesis that there is a kind of reasoning, generic reasoning, previously unrecognized as an independent type of reasoning. A theory of generic reasoning explains how a single significant instance may support general conclusions, with possible exceptions being tolerated. This paper will adopt, as a working hypothesis, that generic reasoning is irreducible to currently recognized kinds of ‘pure’ reasoning. The aim is to understand generic reasoning, both theoretically and in its applications. (shrink)

Generics (e.g., “Ravens are black”) express generalizations about categories or their members. Previous research found that generics about animals are interpreted as broadly true of members of a kind, yet also accepted based on minimal evidence. This asymmetry is important for suggesting a mechanism by which unfounded generalizations may flourish; yet, little is known whether this finding extends to generics about groups of people (heretofore, “social generics”). Accordingly, in four preregistered studies (n = 665), we tested for an inferential asymmetry (...) for generics regarding novel groups of animals versus people. Participants were randomly assigned to either an Implied Prevalence task (given a generic, asked to estimate the prevalence of a property) or a Truth-Conditions task (given prevalence information, asked whether a generic was true or false). A generic asymmetry was found in both domains, at equivalent levels. The asymmetry also extended to properties varying in valence (dangerous and neutral). Finally, there were differences as a function of property valence in the Implied Prevalence task and a small but consistent interaction between domain and prevalence in the Truth-Conditions task. We discuss the implications of these results for the semantics of generics, theoretical accounts of the asymmetry, and the relation between generics and stereotyping. (shrink)
