Do we apply higher epistemic standards to subjects with high stakes? This paper argues that we expect different outward behavior from high-stakes subjects—for example, we expect them to collect more evidence than their low-stakes counterparts—but not because of any change in epistemic standards. Rather, we naturally expect subjects in any condition to think in a roughly adaptive manner, balancing the expected costs of additional evidence collection against the expected value of gains in accuracy. The paper reviews a body of (...) empirical work on the automatic regulation of cognitive effort in response to stakes, and argues that we naturally see high- and low-stakes subjects as experiencing different levels of ‘epistemic anxiety’, and anticipate different levels of cognitive effort from them for this reason. If unresolved epistemic anxiety always bars an ascription of knowledge, then we can explain our responses to cases involving shifting stakes without positing any variation in the standards of intuitive knowledge ascription.

Contextualists support their view by appeal to cases which show that whether an attribution of knowledge seems correct depends on attributor factors. Contextualists conclude that the truth-conditions of knowledge attributions depend on the attributor's context. Invariantists respond that these cases show only that the warranted assertability-conditions of knowledge attributions depend on the attributor's context. I examine DeRose's recent argument against the possibility of such an invariantist response, an argument which appeals to the knowledge account of assertion and the context-sensitivity of (...) assertion. I argue that DeRose's new argument does not rule out either of the two forms of invariantism, classic and subject-sensitive invariantism. Further, I argue against DeRose that an invariantist can explain the context-sensitivity of assertion. (shrink)

Moderate invariantism is the orthodox semantics for knowledge attributions. In recent years it has fallen out of favour, in large part because it fails to explain why ordinary speakers have the intuition that some utterances of knowledge attributions are felicitous and others infelicitous in several types of cases. To address this issue moderate invariantists have developed a variety of what I call non-semantic theories which they claim account for the relevant felicity intuitions independently of moderate invariantist semantics. Some critics (...) have responded by arguing that these non-semantic theories are implausible for one or more of the following reasons: they do not have a basis in empirical data or established theory; they do not account for all of the relevant felicity intuitions; they are ad hoc; or they in fact explain too many felicity intuitions and thus undermine the...

Contribution to a symposium on Keith DeRose's The Case for Contextualism, Volume 1.

Recently, Casasanto and Lupyan (2015) have asserted that there are no context-independent concepts: all concepts are constructed ad hoc when they are instantiated. My aim is to show that the ad hoc cognition framework can be characterized by a similarity-based theory of concepts, and that two different notions of concept should be distinguished —which may be identified with two distinct stages of their life cycle (storage and instantiation). This approach brings together virtues from opposing views: (a) invariantist: stored concepts are (...) stable enough to collect new information; (b) contextualist: instantiated concepts are context-dependent, what explains our adaptive ability to changing environments. (shrink)

In this thesis, I explore a number of epistemological issues concerning the relations between knowledge, belief and practical matters. In particular, I defend a view, which I call credal pragmatism. This view is compatible with moderate invariantism, a view that takes knowledge to depend exclusively on truth-relevant factors and to require an invariant epistemic standard of knowledge that can be quite easily met. The thesis includes a negative and a positive part. In the negative part I do two things: (...) i) I critically examine some moderate invariantist accounts of the intuitive influence of practical factors on knowledge ascriptions, and ii) I provide a criticism of the idea that knowledge is the norm of practical reasoning. In Chapter 1, I provide a general overview of the issues that constitute the background for the views and arguments defended in my thesis. In particular, I provide a thorough discussion of two aspects of the relation between knowledge and practical matters: one is constituted by the practical factors’ effects on knowledge ascriptions; the other is the intuitive normative role of knowledge in the regulation and assessments of action and practical reasoning. In Chapter 2, I consider and criticize Timothy Williamson’s account according to which an alleged failure to acknowledge the distinction between knowing and knowing that one knows generates the intuition that knowledge ascriptions are sensitive to practical factors. In Chapter 3, I argue against the idea that practical reasoning is governed by a knowledge norm. The argument generalizes to other candidate epistemic norms of practical reasoning. In Chapter 4, I criticise a number of accounts which explain effects of practical factors on knowledge ascriptions in terms of the influence of practical factors on belief. These include the accounts of Brain Weatherson, Dorit Ganson, Kent Bach and Jennifer Nagel. In the positive part of the thesis, I develop and argue for credal pragmatism, an original account of the nature and interaction of different doxastic attitudes and the role of practical factors in their rational regulation. On this view, given a certain fixed amount of evidence, the degree of credence of an adaptively rational agent varies in different circumstances depending on practical factors, while the threshold on the degree of credence necessary for outright belief remains fixed across contexts. This account distinguishes between two kinds of outright belief: occurrent belief, which depends on the actual degree of credence, and dispositional belief, which depends on the degree of credence in normal circumstances. In Chapter 5, I present the view and I show how credal pragmatism can explain the practical factors’ effects on knowledge ascriptions. In Chapter 6, I develop a fallibilist account of several features about knowledge ascriptions including i) why in folk epistemological practices knowledge is often taken to be a necessary and sufficient epistemic condition for relying on a proposition in practical reasoning; ii) concessive knowledge attributions and related data; and iii) the infallibilist intuition that knowledge excludes error possibilities.

The aim of this paper is to sketch an approach for integrating the historiography of the sciences and of philosophy. More precisely, the paper suggests a method for investigating interactions within transdisciplinary constellations of researchers working in philosophy and in the exact sciences. I start off by introducing specific notions of analogy, variation, and conceptual space which provide the main ingredients of this method. The notion of a conceptual space, as well as other characteristics of the present approach, are adaptations (...) from so-called constellation research. Originally, constellation research was developed for the historiography of philosophy – especially in the context of the origins of German idealism. However, as I will argue in the second half of the paper, it is adaptable to the historiography of science, especially of the exact sciences. To support this claim and to illustrate the integrative power of the present approach, I will compare the notions of a constellation and a conceptual space with Ludwik Fleck’s notions of a »thought collective« and a »style of thought«, critically evaluate the distinction between contexts of discovery and of justification in a historiographical context, and relate the notions of analogy and variation, as introduced in the first part of the paper, to current debates about what is sometimes called »invariantism« in the philosophy of science.

It is often assumed that adaptation — a temporary change in sensitivity to a perceptual dimension following exposure to that dimension — is a litmus test for what is and is not a “primary visual attribute”. Thus, papers purporting to find evidence of number adaptation motivate a claim of great philosophical significance: That number is something that can be seen in much the way that canonical visual features, like color, contrast, size, and speed, can. Fifteen years after its reported discovery, (...) number adaptation’s existence seems to be nearly undisputed, with dozens of papers documenting support for the phenomenon. The aim of this paper is to offer a counterweight — to critically assess the evidence for and against number adaptation. After surveying the many reasons for thinking that number adaptation exists, we introduce several lesser-known reasons to be skeptical. We then advance an alternative account — the old news hypothesis — which can accommodate previously published findings while explaining various (otherwise unexplained) anomalies in the existing literature. Next, we describe the results of eight pre-registered experiments which pit our novel old news hypothesis against the received number adaptation hypothesis. Collectively, the results of these experiments undermine the number adaptation hypothesis on several fronts, whilst consistently supporting the old news hypothesis. More broadly our work raises questions about the status of adaptation itself as a means of discerning what is and is not a visual attribute. (shrink)

In this essay I show how to reconcile epistemic invariantism with the knowledge account of assertion. My basic proposal is that we can comfortably combine invariantism with the knowledge account of assertion by endorsing contextualism about speech acts. My demonstration takes place against the backdrop of recent contextualist attempts to usurp the knowledge account of assertion, most notably Keith DeRose's influential argument that the knowledge account of assertion spells doom for invariantism and enables contextualism's ascendancy.

In this paper, I explore a range of existent and possible ameliorative semantic theories of gender terms: invariantism, according to which gender terms are not context-sensitive, contextualism, according to which the meaning of gender terms is established in the context of use, and relativism, according to which the meaning of gender terms is established in the context of assessment. I show that none of these views is adequate with respect to the plight of trans people to use their term (...) of choice to self-identify and be referred to accordingly. I then consider an invariantist view based on self-identification and explore some of its challenges. (shrink)

The visual system adapts to a wide range of visual features, from lower-level features like color and motion to higher-level features like causality and, perhaps, number. According to some, adaptation is a strictly perceptual phenomenon, such that the presence of adaptation licenses the claim that a feature is truly perceptual in nature. Given the theoretical importance of claims about adaptation, then, it is important to understand exactly when the visual system does and does not exhibit adaptation. Here, we take as (...) a case study one specific kind of adaptation: visual adaptation to size. Supported by evidence from four experiments, we argue that, despite robust effects of size adaptation in the lab, (1) size adaptation effects are phenomenologically underwhelming (in some cases, hardly appreciable at all), (2) some effects of size adaptation appear contradictory, and difficult to explain given current theories of size adaptation, and (3) prior studies on size adaptation may have failed to isolate size as the adapted dimension. Ultimately, we argue that while there is evidence to license the claim that size adaptation is genuine, size adaptation is a puzzling and poorly understood phenomenon. (shrink)

In this paper I consider the prospects for a skeptical version of infallibilism. For the reasons given above, I think skeptical invariantism has a lot going for it. However, a satisfactory theory of knowledge must account for all of our desiderata, including that our ordinary knowledge attributions are appropriate. This last part will not be easy for the infallibilist invariantist. Indeed, I will argue that it is much more difficult than those sympathetic to skepticism have acknowledged, as there are (...) serious problems with regarding paradigmatic, typical knowledge attributions as loose talk, exaggerations, or otherwise practical uses of language. So, I do not think the pragmatic story that skeptical invariantism needs is one that works without a supplemental error theory of the sort left aside by purely pragmatic accounts of knowledge attributions. In its place, I will offer a compromise pragmatic and error view that I think delivers everything that skeptics can reasonably hope to get. (shrink)

A certain number of cases suggest that our willingness to ascribe “knowledge” can be influenced by practical factors. For revisionary proposals, they indicate that the truth‐values of “knowledge” ascriptions vary with practical factors. For conservative proposals, on the contrary, nothing surprising is happening. Standard pragmatic approaches appeal to pragmatic implicatures and psychological approaches to the idea that belief formation is influenced by practical factors. Conservative proposals have not yet offered a fully satisfactory explanation, though. In this article, I introduce and (...) defend a third conservative proposal which I call “Refined Invariantism”. The two main claims of this proposal are that (1) we should distinguish between high stakes cases in which the subject does not believe (that he knows) the target proposition and those in which he believes (that he knows) the target proposition and that (2) we should adopt a psychological treatment for the first kind of case and a pragmatic treatment based on the epistemic standards for appropriate assertion and action for the second kind of case. I argue that this new combined approach avoids the main pitfalls of its two conservative rivals and that it gives new life to the generality objection levelled against revisionary views. (shrink)

Epistemic invariantism, or invariantism for short, is the position that the proposition expressed by knowledge sentences does not vary with the epistemic standard of the context in which these sentences can be used. At least one of the major challenges for invariantism is to explain our intuitions about scenarios such as the so-called bank cases. These cases elicit intuitions to the effect that the truth-value of knowledge sentences varies with the epistemic standard of the context in which (...) these sentences can be used. In this paper, I will defend invariantism against this challenge by advocating the following, somewhat deflationary account of the bank case intuitions: Readers of the bank cases assign different truth-values to the knowledge claims in the bank cases because they interpret these scenarios such that the epistemic position of the subject in question differs between the high and the low standards case. To substantiate this account, I will argue, first, that the bank cases are underspecified even with respect to features that should uncontroversially be relevant for the epistemic position of the subject in question. Second, I will argue that readers of the bank cases will fill in these features differently in the low and the high standards case. In particular, I will argue that there is a variety of reasons to think that the fact that an error-possibility is mentioned in the high standards case will lead readers to assume that this error-possibility is supposed to be likely in the high standards case.

Invariantism proposed by Braun (Linguistics and Philosophy 35(6):461–489, 2012) aims to maintain full identity of semantic content between all uses of ‘might’. I invoke well-known facts regarding diachronic change in meanings of modals to argue that invariantism commits us to implausible duplication of familiar processes of lexical semantic change on the level of “lexical pragmatics”, with no obvious payoff.

Simply stated, Pragmatic Invariantism is the view that the practical interests of a person can influence whether that person’s true belief constitutes knowledge. My primary objective in this article is to show that Pragmatic Invariantism entails external world skepticism. Toward this end, I’ll first introduce a basic version of Pragmatic Invariantism (PI). Then I’ll introduce a sample skeptical hypothesis (SK) to the framework. From this I will show that it is extremely important that the phenomenally equivalent skeptical (...) scenarios generated by SK are actually false. We’ll then see that by combining PI and SK, the effect will be to place extremelyhigh demands upon evidence for ~SK. It will finally be observed that, while we may have good evidence for ~SK, we do not have extremely strong evidence sufficient for establishing ~SK. This supports my conclusion that any standard version of Pragmatic Invariantism ultimately entails external world skepticism. If successful, my conclusion will critically undermine the current view that Pragmatic Invariantism is actually a skeptically resistant position. (shrink)

Invariantism about ‘might’ says that ‘might’ semantically expresses the same modal property in every context. This paper presents and defends a version of invariantism. According to it, ‘might’ semantically expresses the same weak modal property in every context. However, speakers who utter sentences containing ‘might’ typically assert propositions concerning stronger types of modality, including epistemic modality. This theory can explain the phenomena that motivate contextualist theories of epistemic uses of ‘might’, and can be defended from objections of the (...) sort that relativists mount against contextualist theories. (shrink)

Epistemic contextualism, many critics argue, entails that ordinary speakers are blind to the fact that knowledge claims have context-sensitive truth conditions. This attribution of blindness, critics add, seriously undermines contextualism. I show that this criticism and, in general, discussions about the error theory entailed by contextualism, greatly underestimates the complexity and diversity of the data about ordinary speakers? inter-contextual judgments, as well as the range of explanatory moves that are open to both invariantists and contextualists concerning such judgments. Contextualism does (...) entail that some speakers suffer from semantic blindness; however, at its roots, this blindness concerns not the context-sensitivity of knowledge claims, but the question whether knowledge sentences possess context-independent truth conditions. I argue that this blindness should not be deemed problematic, but that invariantism entails an error theory that is, by comparison, much more troubling. (shrink)

Causal contextualism holds that sentences of the form ‘c causes e’ have context-sensitive truth-conditions. We consider four arguments invoked by Jonathan Schaffer in favor of this view. First, he argues that his brand of contextualism helps solve puzzles about transitivity. Second, he contends that how one describes the relata of the causal relation sometimes affects the truth of one’s claim. Third, Schaffer invokes the phenomenon of contrastive focus to conclude that causal statements implicitly designate salient alternatives to the cause and (...) effect. Fourth, he claims that the appropriateness of a causal statement depends on what is contextually taken for granted or made salient. We show that causal invariantism can explain these linguistic data at least as well as contextualism. We then argue that pace Schaffer, some causal sentences are always correct and can never be plausibly denied, regardless of the context. (shrink)

Jessica Brown effectively contends that Keith DeRose’s latest argument for contextualism fails to rule out contextualism’s chief rival, namely, classic invariantism. Still, even if her position has not been ruled out, the classic invariantist must offer considerations in favor of her position if she is to convince us that it is superior to contextualism. Brown defends classic invariantism with a warranted assertability maneuver that utilizes a linguistic pragmatic principle of relevance. I argue, however, that this maneuver is not (...) as effective as it might be. I propose a different warranted assertability maneuver—one that utilizes a pragmatic principle of strength—that affords a more successful defense of classic invariantism, and that helps to establish that classic invariantism is superior to contextualism.

According to the Epistemic Theory of Mind, knowledge is part of the best overall framework for explaining behavior at the psychological level. This theory, which has become increasingly popular in recent decades, has almost always been conjoined with an invariantist theory of “knows.” In this paper, I argue that this is a mistake: the Epistemic Theory of Mind is far more explanatorily powerful when conjoined with contextualism. I conclude that if the Epistemic Theory of Mind is true, then there is (...) a powerful new reason to accept contextualism. (shrink)

This paper revisits a puzzle that arises for theories of knowledge according to which one can know on the basis of merely inductive grounds. No matter how strong such theories require inductive grounds to be if a belief based on them is to qualify as knowledge, there are certain beliefs that are based on even stronger inductive grounds, while, intuitively, they do not qualify as knowledge. This paper discusses what is often regardedas the most promising classical invariantist solution to the (...) puzzle, namely, that beliefs about the outcomes of fair lotteries do not qualify as knowledge because they are too lucky to do so, while other beliefs based on potentially weaker inductive grounds are not too lucky. A case is presented that shows that this solution to the puzzle is actually not viable. It is argued that there is no obvious alternative solution in sight and that therefore the puzzle still awaits a classical invariantist solution. (shrink)

In this paper, I will discuss what I will call “skeptical pragmatic invariantism” as a potential response to the intuitions we have about scenarios such as the so-called bank cases. SPI, very roughly, is a form of epistemic invariantism that says the following: The subject in the bank cases doesn’t know that the bank will be open. The knowledge ascription in the low standards case seems appropriate nevertheless because it has a true implicature. The goal of this paper (...) is to show that SPI is mistaken. In particular, I will show that SPI is incompatible with reasonable assumptions about how we are aware of the presence of implicatures. Such objections are not new, but extant formulations are wanting for reasons I will point out below. One may worry that refuting SPI is not a worthwhile project given that this view is an implausible minority position anyway. To respond, I will argue that, contrary to common opinion, other familiar objections to SPI fail and, thus, that SPI is a promising position to begin with. (shrink)

I introduce and defend a view about knowledge that I call Moderate Skeptical Invariantism. According to this view, a subject knows p only if she is practically certain that p, where practical certainty is defined as the confidence a rational subject would have to have for her to believe that p and act on p no matter the stakes. I do not provide a definitive case for this view, but I argue that it has several explanatory advantages over alternative (...) views and I show how it can avoid two pressing problems commonly addressed to similar approaches.

§I schematises the evidence for an understanding of ‘know’ and other terms of epistemic appraisal that embodies contextualism or subject-sensitive invariantism, and distinguishes between those two approaches. §II argues that although the cases for contextualism and sensitive invariantism rely on a principle of charity in the interpretation of epistemic claims, neither approach satisfies charity fully, since both attribute metalinguistic errors to speakers. §III provides an equally charitable anti-sceptical insensitive invariantist explanation of much of the same evidence as the (...) result of psychological bias caused by salience effects. §IV suggests that the explanation appears to have implausible consequences about practical reasoning, but also that applications of contextualism or sensitive invariantism to the problem of scepticism have such consequences. §V argues that the inevitable difference between appropriateness and knowledge of appropriateness in practical reasoning, closely related to the difference between knowledge and knowledge of knowledge, explains the apparent implausibility.

In Knowledge and its Limits (KAIL), Timothy Williamson argues for the view that “only knowledge warrants assertion” (2000, 243). Call this the knowledge norm of assertion. Several philosophers including DeRose, Hawthorne, and Stanley, agree that if the knowledge norm is true, then knowledge itself depends on stakes, since warranted assertability seems to change with what is at stake if the proposition in question is true (1992; 2003; 2005). This brings us to the question: stakes for whom? DeRose maintains that knowledge (...) depends on the stakes for the speaker of the knowledge attribution, arguing for Epistemic Contextualism (2002, 187). However, Hawthorne and Stanley disagree, contending that it is the stakes for the subject of the knowledge attribution which is relevant, arguing for Subject Sensitive Invariantism (2003, 157; 2005, 85). While the Contextualist and the Invariantist are armed with responses against each other’s view, I suspect that Russell’s and Doris’ indifference cases might break the impasse in favor of the Contextualist (2008, 432). This paper will thus attempt to show that the knowledge norm of assertion leads us to Contextualism rather than Subject Sensitive Invariantism, by comparing how Contextualism and Subject Sensitive Invariantism fare against Russell’s and Doris’ Indifference Cases.

Moral responsibility invariantism is the view that there is a single set of conditions for being morally responsible for an action (or omission or consequence of an act or omission) that applies in all cases. I defend this view against some recent arguments by Joshua Knobe and John Doris.

Moderate Pragmatic Invariantism has been criticized in the literature for postulating implicatures that are not straightforwardly cancellable. Defenders of MPI have responded that the data are not as clear-cut as one might wish. This paper grants the defenders of MPI, for the sake of argument, that the implicatures in question are cancellable and then turns this admission against them. In particular, the paper offers Bank Case variants in which the conversational implicatures postulated by MPI are contextually suspended – and (...) thus cancelled. Since our intuitions do not vary between the original Bank Case and these novel types of cases, the explanation offered by MPI must be mistaken. Our varying truth-value intuitions in the Bank Cases cannot be accounted for by means of conversational implicatures. (shrink)

Strict moderate invariantism is the ho-hum, ‘obvious’ view about knowledge attributions. It says knowledge attributions are often true and that only traditional epistemic factors like belief, truth, and justification make them true. As commonsensical as strict moderate invariantism is, it is equally natural to withdraw a knowledge attribution when error possibilities are made salient. If strict moderate invariantism is true, these knowledge-denials are often false because the subject does in fact know the proposition. I argue that strict (...) moderate invariantism needs an explanation of this phenomenon, but it does not have one. That is significant, for if strict moderate invariantism does not square with ordinary intuition, then it cannot rely on ordinary intuition for support. Section 1 introduces the concept of epistemic relevance blindness, which says ordinary subjects are generally insensitive to whether or not error possibilities are relevant to knowledge attributions. Section 2 focuses on Patrick Rysiew’s influential strict moderate invariantist pragmatic explanation of knowledge-denials and argues that such pragmatic explanations of knowledge-denials depend on attributors being epistemic relevance blind. Section 3 targets psychological explanations of epistemic relevance blindness offered separately by Jennifer Nagel and Mikkel Gerken. I argue that strict moderate invariantists lack a plausible explanation of epistemic relevance blindness. (shrink)

This collection of original essays explores the topic of skeptical invariantism in theory of knowledge. It eschews historical perspectives and focuses on this traditionally underexplored, semantic characterization of skepticism. The book provides a carefully structured, state-of-the-art overview of skeptical invariantism and offers up new questions and avenues for future research. It treats this semantic form of skepticism as a serious position rather than assuming that skepticism is false and attempting to diagnose where arguments for skepticism go wrong. The (...) essays take up a wide range of different philosophical perspectives on three key questions in the debate about skeptical invariantism: whether the standards for knowledge vary, how demanding the standards for knowledge are, and whether the kind of evidence, reasons, methods, processes etc. that we can bring to bear are sufficient to meet those standards. Skeptical Invariantism Reconsidered will be of interest to scholars and advanced students in epistemology and philosophy of language. (shrink)

I defend interest-relative invariantism from a number of recent attacks. One common thread to my response is that interest-relative invariantism is a muchweaker thesis than is often acknowledged, and a number of the attacks only challenge very specific, and I think implausible, versions of it. Another is that a number of the attacks fail to acknowledge how many things we have independent reason to believe knowledge is sensitive to. Whether there is a defeater for someone's knowledge can be (...) sensitive to all manner of features of their environment, as the host of examples from the post-Gettier literature shows. Adding in interest-sensitive defeaters is a much less radical move than most critics claim it is. (shrink)

Jennifer Lackey challenges the sufficiency version of the knowledge-action principle, viz., that knowledge that p is sufficient to rationally act on p, by proposing a set of alleged counterexamples. Her aim is not only to attack the knowledge-action principle, but also to undermine an argument for subject-sensitive invariantism. Lackey holds that her examples are counterexamples to the sufficiency version of the knowledge-action principle because (a) S knows the proposition in question, but (b) it is not rational for S to (...) act on it. In this paper, first, I argue against (a) on intuitive and on theoretical grounds. Second, I point out that (b), even if combined with (a), is not sufficient to make for counterexamples to the knowledge-action principle of the relevant kind. Third, I offer two alternative explanations of the intuition Lackey relies on. If either one of them is right, (b) may not be satisfied in her examples. (shrink)

Braun (Linguistics & Philosophy 35, 461–489, 2012) argued for a non- relativist, invariantist theory of ‘might’. Yanovich (Linguistics & Philosophy, 2013) argues that Braun’s theory is inconsistent with certain facts concerning diachronic meaning changes in ‘might’, ‘can’, and ‘may’. This paper replies to Yanovich’s objection.

I present an argument for a sophisticated version of sceptical invariantism that has so far gone unnoticed: Bifurcated Sceptical Invariantism (BSI). I argue that it can, on the one hand, (dis)solve the Gettier problem, address the dogmatism paradox and, on the other hand, show some due respect to the Moorean methodological incentive of ‘saving epistemic appearances’. A fortiori, BSI promises to reap some other important explanatory fruit that I go on to adduce (e.g. account for concessive knowledge attributions). (...) BSI can achieve this much because it distinguishes between two distinct but closely interrelated (sub)concepts of (propositional) knowledge, fallible-but-safe knowledge and infallible-and-sensitive knowledge, and explains how the pragmatics and the semantics of knowledge discourse operate at the interface of these two (sub)concepts of knowledge. I conclude that BSI is a novel theory of knowledge discourse that merits serious investigation. (shrink)

Jason Stanley has argued recently that Epistemic Contextualism (EC) and Subject‐Sensitive Invariantism (SSI) are explanatorily on a par with regard to certain data arising from modal and temporal embeddings of ‘knowledge’‐ascriptions. This paper argues against Stanley that EC has a clear advantage over SSI in the discussed field and introduces a new type of linguistic datum strongly suggesting the falsity of SSI.

Avoiding severe impacts from anthropogenic climate change requires not only substantial reductions in greenhouse gas emissions but also further implementation of adaptation measures. In many regions with smallholder farming systems adaptation can help ensure food security despite significantly changing climatic conditions. However, the space for adaptation measures has limits. In this paper, we investigate hard and soft adaptation limits and discuss their relevance to food security in smallholder farming food systems. We argue that soft adaptation limits can be defined by (...) sufficiency levels of justice like basic needs, capabilities, human rights or levels of well-being. Depending on social, cultural, political and economic conditions different communities realize different sufficiency levels of justice. Furthermore, as normative claims of justice, these sufficiency levels not only allow the social, cultural and political and economic conditions of social systems to be described but also define entitlements. We show that for smallholder farming systems with low social and economic standards these entitlements might mean that soft adaptation limits can define entitlements to social and economic improvements despite transformational adaptation to changing climatic conditions.
