Uncertainty is recognized as a key issue in water resources research, amongst other sciences. Discussions of uncertainty typically focus on tools and techniques applied within an analysis, e.g. uncertainty quantification and model validation. But uncertainty is also addressed outside the analysis, in writing scientific publications. The language that authors use conveys their perspective of the role of uncertainty when interpreting a claim —what we call here “framing” the uncertainty. This article promotes awareness of uncertainty framing in four ways. 1) It (...) proposes a typology of eighteen uncertainty frames, addressing five questions about uncertainty. 2) It describes the context in which uncertainty framing occurs. This is an interdisciplinary topic, involving philosophy of science, science studies, linguistics, rhetoric, and argumentation. 3) We analyze the use of uncertainty frames in a sample of 177 abstracts from the Water Resources Research journal in 2015. This helped develop and tentatively verify the typology, and provides a snapshot of current practice. 4) Provocative recommendations promote adjustments for a more influential, dynamic science. Current practice in uncertainty framing might be described as carefully-considered incremental science. In addition to uncertainty quantification and degree of belief (present in ~5% of abstracts), uncertainty is addressed by a combination of limiting scope, deferring to further work (~25%) and indicating evidence is sufficient (~40%) – or uncertainty is completely ignored (~8%). There is a need for public debate within our discipline to decide in what context different uncertainty frames are appropriate. Uncertainty framing cannot remain a hidden practice evaluated only by lone reviewers. (shrink)

The concepts we use to value and prescribe are historically contingent, and we could have found ourselves with others. But what does it mean to say that some concepts are better than others for purposes of action-guiding and deliberation? What is it to choose between different normative conceptual frameworks?

The article is centered on the question of how best to understand the logical pluralism/logical monism debate. A number of suggestions are brought up and rejected on the ground that they re...

The main thesis of this paper is that we sometimes are disposed to accept false and even jointly inconsistent claims by virtue of our semantic competence, and that this comes to light in the sorites and liar paradoxes. Among the subsidiary theses are that this is an important source of indeterminacy in truth conditions, that we must revise basic assumptions about semantic competence, and that classical logic and bivalence can be upheld in the face of the sorites paradox.

My focus here will be Rudolf Carnap’s views on ontology, as these are presented in the seminal “Empiricism, Semantics and Ontology” (1950). I will first describe how I think Carnap’s distinction between external and internal questions is best understood. Then I will turn to broader issues regarding Carnap’s views on ontology. With certain reservations, I will ascribe to Carnap an ontological pluralist position roughly similar to the positions of Eli Hirsch and the later Hilary Putnam. Then I turn to some (...) interrelated arguments against the pluralist view. The arguments are not demonstrative. Some possible escape routes for the pluralist are outlined. But I think the arguments constitute a formidable challenge. There should be serious doubt as to whether the pluralist view, as it emerges after discussion of these arguments, will be worth defending. Moreover, there is an alternative ontological view which equally well subserves the motivations underlying ontological pluralism. (shrink)

Antinatalism is an emerging philosophy and practice that challenges pronatalism, the prevailing philosophy and practice in reproductive matters. We explore justifications of antinatalism—the arguments from the quality of life, the risk of an intolerable life, the lack of consent, and the asymmetry of good and bad—and argue that none of them supports a concrete, understandable, and convincing moral case for not having children. We identify concentration on possible future individuals who may or may not come to be as the main (...) culprit for the failure and suggest that the focus should be shifted to people who already exist. Pronatalism’s hegemonic status in contemporary societies imposes upon us a lifestyle that we have not chosen yet find almost impossible to abandon. We explicate the nature of this imposition and consider the implications of its exposure to different stakeholders with varying stands on the practice of antinatalism. Imposition as a term has figured in reproductive debates before, but the argument from postnatal, mental, and cultural imposition we launch is new. It is the hitherto overlooked and underdeveloped justification of antinatalism that should be solid and comprehensible enough to be used even by activists in support of their work. (shrink)

Is the tendency to morally prioritize humans over animals weaker in children than adults? In two pre-registered studies (N = 622), 5- to 9-year-old children and adults were presented with moral dilemmas pitting varying numbers of humans against varying numbers of either dogs or pigs and were asked who should be saved. In both studies, children had a weaker tendency to prioritize humans over animals than adults. They often chose to save multiple dogs over one human, and many valued the (...) life of a dog as much as the life of a human. While they valued pigs less, the majority still prioritized ten pigs over one human. By contrast, almost all adults chose to save one human over even one hundred dogs or pigs. Our findings suggest that the common view that humans are far more morally important than animals appears late in development and is likely socially acquired. (shrink)

Neo-Fregeanism in the philosophy of mathematics consists of two main parts: the logicist thesis, that mathematics (or at least branches thereof, like arithmetic) all but reduce to logic, and the platonist thesis, that there are abstract, mathematical objects. I will here focus on the ontological thesis, platonism. Neo-Fregeanism has been widely discussed in recent years. Mostly the discussion has focused on issues specific to mathematics. I will here single out for special attention the view on ontology which underlies the neo-Fregeans’ (...) claims about mathematical objects, and discuss this view in a broader setting. (shrink)

Many theorists hold that there is, among value concepts, a fundamental distinction between thin ones and thick ones. Among thin ones are concepts like good and right. Among concepts that have been regarded as thick are discretion, caution, enterprise, industry, assiduity, frugality, economy, good sense, prudence, discernment, treachery, promise, brutality, courage, coward, lie, gratitude, lewd, perverted, rude, glorious, graceful, exploited, and, of course, many others. Roughly speaking, thick concepts are value concepts with significant descriptive content. I will discuss a number (...) of problems having to do with how best to understand the notion of a thick concept. Thick concepts have been widely discussed in the .. (shrink)

(1) Abstract objects. The nominalist (as the label is used today) denies that there exist abstract objects. The platonist holds that there are abstract objects. One example is numbers. The nominalist denies that there are numbers; the platonist typically affirms it.

Utilitarianism could still be a viable moral and political theory, although an emphasis on justice as distributing burdens and benefits has hidden this from current conversations. The traditional counterexamples prove that we have good grounds for rejecting classical, aggregative forms of consequentialism. A nonaggregative, liberal form of utilitarianism is immune to this rejection. The cost is that it cannot adjudicate when the basic needs of individuals or groups are in conflict. Cases like this must be solved by other methods. This (...) is not a weakness in liberal utilitarianism, on the contrary. The theory clarifies what we should admit to begin with: that ethical doctrines do not have universally acceptable solutions to all difficult problems or hard cases. The theory also reminds us that not all problems are in this sense difficult or cases hard. We could alleviate the plight of nonhuman animals by reducing meat eating. We could mitigate climate change and its detrimental effects by choosing better ways of living. These would imply that most people’s desire satisfaction would be partly frustrated, but liberal utilitarianism holds that this would be justified by the satisfaction of the basic needs of other people and nonhuman animals.

This article presents a revised version of negative utilitarianism. Previous versions have relied on a hedonistic theory of value and stated that suffering should be minimized. The traditional rebuttal is that the doctrine in this form morally requires us to end all sentient life. To avoid this, a need-based theory of value is introduced. The frustration of the needs not to suffer and not to have one’s autonomy dwarfed should,prima facie, be decreased. When decreasing the need frustration of some would (...) increase the need frustration of others, the case is deferred and a fuller ethical analysis is conducted. The author’s perceptions on murder, extinction, the right to die, antinatalism, veganism, and abortion are used to reach a reflective equilibrium. The new theory is then applied to consumerism, material growth, and power relations. The main finding is that the burden of proof should be on those who promote thestatus quo. (shrink)

Forthcoming in Darren Bradley (ed.), Carnap and Contemporary Philosophy. -/- This paper is centered on Carnap’s views on rationality. More specifically, much of the focus is on a puzzle regarding Carnap’s view on rationality that Florian Steinberger has recently discussed. Not only is Steinberger’s discussion of significant intrinsic interest: his discussion also raises general questions about Carnap interpretation. As I have discussed in earlier work, there are two very different ways of interpreting Carnap’s talk of “frameworks” – and, relatedly, different (...) ways of interpreting Carnap’s principle of tolerance. Carnap can be interpreted as either a relativist or as what I call a language pluralist. Steinberger’s puzzle arises given the relativist interpretation; I believe the language pluralist interpretation is correct. Most of the discussion will concern the correct interpretation of Carnap, and what this means for Steinberger’s puzzle. While I will not here mount a full defense of the language pluralist interpretation, I will pause to discuss Vera Flocke’s recent criticism of it. Towards the end, I will describe a puzzle regarding rationality different from Steinberger’s. The puzzle that I describe does arise already for the language pluralist. (shrink)

The main question of the paper is that ofwhat vagueness consists in. This question must be distinguished from other questions about vagueness discussed in the literature. It is argued that familiar accounts of vagueness for general reasons failto answer the question ofwhat vagueness consists in. A positive view is defended, according to which, roughly, the vagueness of an expression consists in it being part ofsemantic competence to accept a tolerance principle for the expression. Since tolerance principles are inconsistent, this is (...) an inconsistency view on vagueness. (shrink)

Metaontology – the study of the nature of ontological issues – has flourished in recent years. The focus of this summary will be on some views and arguments that are central to today’s debate. One theme will be that of how seriously to take ontology: whether there is reason to take a skeptical or deflationary attitude toward ontological claims, as theorists like Rudolf Carnap, Hilary Putnam, and Eli Hirsch in different ways have urged. The other theme will be that of (...) the viability of the Fregean and Quinean approaches to ontology that have been and still are central to analytic philosophy. (shrink)

Mark Johnston and Eric Olson have both pressed what Johnston has dubbed the personite problem. Personites, if they exist, are person-like entities whose lives extend over a continuous proper part of a person’s life. They are so person-like that they seem to have moral status if persons do. But this threatens to wreak havoc with ordinary moral thinking. For example, simple decisions to suffer some short-term hardship for long-term benefits become problematic. And ordinary punishment is always also punishment of the (...) innocent, since it punishes personites that didn’t exist when the crime was committed. An initially attractive way around the personite problem may be to simply deny that personites exist. But as I discuss in this talk, relating to contemporary discussions in metaontology, this response for principled reasons doesn’t work. The problems I discuss illustrate the significance of metaontological considerations for issues in ethics and metaethics, and generalize widely beyond the personite problem. (shrink)

The article is an extended critical discussion of Kevin Scharp’s Replacing Truth. Scharp’s case for the claim that the concept of truth is inconsistent is criticized, and so is his case for the claim that the concept of truth must be replaced because of its inconsistency.

_Liberal Utilitarianism and Applied Ethics_ explores the foundations of early utilitarianism and, at the same time, the theoretical bases of social ethics and policy in modern Western welfare states. Matti Hayry sees the main reason for utilitarianism's growing disrepute among moral philosophers is that its principles cannot legitimately be extended to situations where the basic needs of the individuals involved are in conflict. He is able to formulate a solution to this fundamental problem by arguing convincingly that by combining (...) a limited version of liberal utilitarianism and the methods of applied ethics, we are able to define our moral duties and rights. _Liberal Utilitarianism and Applied Ethics_ will appeal to students and teachers of philosophy who are interested in the doctrine of utilitarianism or in ethical decison-making.

I discuss some problems faced by the meaning‐inconsistency view on the liar and sorites paradoxes which I have elsewhere defended. Most of the discussion is devoted to the question of what a defender of the meaning‐inconsistency view should say about semantic competence.

Antinatalism assigns reproduction a negative value. There should be fewer or no births. Those who say that there should be fewer births have been called conditional antinatalists. A better name for their view would be selective pronatalism. Those who say that there should be no births face two challenges. They must define the scope of their no-birth policy. Does it apply only to human or sentient beings or can it also be extended to all organic life, perhaps even to machine (...) consciousness? And whatever the scope, they have to justify the eventual extinction of humankind or other life forms, an inevitable consequence of unconditional antinatalism. Different axiologies and moral theories produce different responses to these challenges. It is argued that a two-value conflict-sensitive negative utilitarianism would produce a kind and reasonable justification for ending at least human and factory-animal reproduction. The conclusion is purely moral and supports only voluntary extinction for humankind. (shrink)

What is deflationism about truth? There are many questions that can be raised about this, given the numerous different characterizations of deflationism in the literature. Here I attend to questions about the characterization of deflationism that arise when we carefully distinguish between issues pertaining to concepts and issues pertaining to properties.

:Justice can be approached from many angles in ethical and political debates, including those involving healthcare, biomedical research, and well-being. The main doctrines of justice are liberal egalitarianism, libertarianism, luck egalitarianism, socialism, utilitarianism, capability approach, communitarianism, and care ethics. These can be further elaborated in the light of traditional moral and social theories, values, ideals, and interests, and there are distinct dimensions of justice that are captured better by some tactics than by others. In this article, questions surrounding these matters (...) are approached with the hermeneutic idea of a distinction between “American” and “European” ways of thinking. (shrink)

I present a qualified new defense of antinatalism. It is intended to empower potential parents who worry about their possible children’s life quality in a world threatened by environmental degradation, climate change, and the like. The main elements of the defense are an understanding of antinatalism’s historical nature and contemporary varieties, a positional theory of value based on Epicurean hedonism and Schopenhauerian pessimism, and a sensitive guide for reproductive decision-making in the light of different views on life’s value and risk-taking. (...) My conclusion, main message, to the concerned would-be parents is threefold. If they believe that life’s ordinary frustrations can make it not worth living, they should not have children. If they believe that a noticeably low life quality makes it not worth living and that such life quality can be reasonably expected, they should not have children, either. If they believe that a noticeably low life quality is not reasonably to be expected or that the risk is worth taking, they can, in the light of their own values and beliefs, have children. The conclusion is supported by a combination of the extant arguments for reproductive abstinence, namely the arguments from consent, moral asymmetry, life quality, and risk. (shrink)

According to a certain pluralist view in philosophy of mathematics, there are as many mathematical objects as there can coherently be. Recently, Justin Clarke-Doane has explored what consequences the analogous view on normative properties would have. What if there is a normative pluriverse? Here I address this same question. The challenge is best seen as a challenge to an important form of normative realism. I criticize the way Clarke-Doane presents the challenge. An improved challenge is presented, and the role of (...) pluralism in this challenge is assessed. (shrink)

In this paper I outline an alternative to hermeneutic fictionalism, an alternative I call indifferentism, with the same advantages as hermeneutic fictionalism with respect to ontological issues but avoiding some of the problems that face fictionalism. The difference between indifferentism and fictionalism is this. The fictionalist about ordinary utterances of a sentence S holds, with more orthodox views, that the speaker in some sense commits herself to the truth of S. It is only that for the fictionalist this is truth (...) in the relevant fiction. According to the indifferentist, by contrast, we are simply non-committal – or indifferent – with respect to some aspects of what is literally said in our assertive utterances. (shrink)

The problem, or cluster of problems, of the unity of the proposition, along with the cluster of problems that tend to go under the name of Bradley’s regress, has recently again become a going concern for philosophers, after having for some time been regarded as primarily of historical interest. In this paper, I distinguish between the different problems that tend to be brought up under the heading of the unity of the proposition, and between different related regress arguments. I present (...) my favored solutions to these problems. (shrink)

I will here present a number of problems concerning the idea that there is ontological vagueness, and the related claim that appeal to this idea can help solve some vagueness-related problems. A theme underlying the discussion will be the distinction between vagueness specifically and indeterminacy more generally (and, relatedly, the distinction between ontological vagueness and ontological indeterminacy). Even if the world is somehow ontologically indeterminate it by no means follows that it is, properly speaking, ontologically vague.1..

Governmental reactions to crises like the COVID-19 pandemic can be seen as ethics communication. Governments can contain the disease and thereby mitigate the detrimental public health impact; allow the virus to spread to reach herd immunity; test, track, isolate, and treat; and suppress the disease regionally. An observation of Sweden and Finland showed a difference in feasible ways to communicate the chosen policy to the citizenry. Sweden assumed the herd immunity strategy and backed it up with health utilitarian arguments. This (...) was easy to communicate to the Swedish people, who appreciated the voluntary restrictions approach and trusted their decision makers. Finland chose the contain and mitigate strategy and was towards the end of the observation period apparently hesitating between suppression and the test, track, isolate, and treat approach. Both are difficult to communicate to the general public accurately, truthfully, and acceptably. Apart from health utilitarian argumentation, something like the republican political philosophy or selective truth telling are needed. The application of republicanism to the issue, however, is problematic, and hiding the truth seems to go against the basic tenets of liberal democracy. (shrink)

Oystein Linnebo's book Thin Objects is partly devoted to defending the view that some objects are “thin” in that their existence does not impose any substantive demands on the world. In this paper, I discuss the concern that the defense relies on there being entities that serve as the referents of predicates. Linnebo thus seems to assume the thinness of those entities. In the course of my discussion, I also discuss what Linnebo says about the role of criteria of identity (...) in his discussion of reference and existence. (shrink)

The aim of the paper is to bring clarity regarding the doctrine of quantifier variance (due to Eli Hirsch), and two prominent arguments against this doctrine, the collapse argument and the Eklund-Hawthorne argument. Different versions of the doctrine of quantifier variance are distinguished, and it is shown that the effectiveness of the arguments against it depends on what version of the doctrine is at issue. The metaontological significance of the different versions of the doctrine are also assessed. Roughly, quantifier variance (...) concerns there being different possible existential quantifier meanings, and often the doctrine involves a claim to the effect there is no unique “best” quantifier meaning. Much of the discussion in the paper concerns what it is to be an existential quantifier meaning in the sense at issue. (shrink)

This chapter discusses the defence of metaphysical indeterminacy by Elizabeth Barnes and Robert Williams and discusses a classical and bivalent theory of such indeterminacy. Even if metaphysical indeterminacy arguably is intelligible, Barnes and Williams argue in favour of it being so and this faces important problems. As for classical logic and bivalence, the chapter problematizes what exactly is at issue in this debate. Can reality not be adequately described using different languages, some classical and some not? Moreover, it is argued (...) that the classical and bivalent theory of Barnes and Williams does not avoid the problems that arise for rival theories. (shrink)

Moral and political philosophers no longer condemn harm inflicted on nonhuman animals as self-evidently as they did when animal welfare and animal rights advocacy was at the forefront in the 1980s, and sentience, suffering, species-typical behavior, and personhood were the basic concepts of the discussion. The article shows this by comparing the determination with which societies seek responsibility for human harm to the relative indifference with which law and morality react to nonhuman harm. When harm is inflicted on humans, policies (...) concerning negligence and duty of care and principles such as the ‘but for’ rule and the doctrine of double effect are easily introduced. When harm is inflicted on nonhumans, this does not happen, at least not any more. As an explanation for the changed situation, the article offers a shift in discussion and its basic terminology. Simple ethical considerations supported the case for nonhuman animals, but many philosophers moved on to debate different views on political justice instead. This allowed the creation of many conflicting views that are justifiable on their own presuppositions. In the absence of a shared foundation, this fragments the discussion, focuses it on humans, and ignores or marginalizes nonhuman animals. (shrink)

I critically discuss Douglas Edwards' construal of the debate over truth, and his case for truth pluralism. Toward the end I present a constructive suggestion on Edwards' behalf. This suggestion avoids the problems I have presented, whatever in the end its fate.

In contemporary philosophy there is much focus on conceptual engineering: the enterprise of revising and replacing concepts. In this talk, I focus on a theoretical issue that has not yet received much attention. What principled limits are there to this sort of enterprise? Are there concepts that for principled reasons cannot or should not be revised or replaced? Examples discussed include logical concepts and normative concepts.

Is there such a thing as corona solidarity? Does voluntary mutual aid solve the problems caused by COVID-19? I argue that the answer to the first question is “yes” and to the second “no.” Not that the answer to the second question could not, in an ideal world, be “yes,” too. It is just that in this world of global capitalism and everybody looking out for themselves, the kind of communal warmth celebrated by the media either does not actually exist (...) or is too weak to rule out the uglier manifestations of group togetherness, driven partly by the pandemic. I make my point by offering two approaches to understanding what solidarity is. According to the first, it is essentially partiality: “us” against “them.” According to the second, it can be many things, including the impartial promotion of the good of others. I show that the second reading would make it possible for mutual aid to solve the problems caused by COVID-19 and other crises. This would happen at the expense of conceptual clarity, but that is a minor concern. The major concern is that the more natural manifestations of group togetherness are incited by negative feelings. This is par for the course within the narrower reading of solidarity, but it means that the potentially positive ideas of identity, care, communal values, and special relations are displayed in violent confrontation instead of a calm recognition of the threats that most of us face together.

The role of bioethicists amidst crises like the COVID-19 pandemic is not well defined. As professionals in the field, they should respond, but how? The observation of the early days of pandemic confinement in Finland showed that moral philosophers with limited experience in bioethics tended to apply their favorite theories to public decisions, with varying results. Medical ethicists were more likely to lend support to the public authorities by soothing or descriptive accounts of the solutions assumed. These are approaches that (...) Tuija Takala has called the firefighting and window dressing models of bioethics. Human rights lawyers drew attention to the flaws of the government’s regulative thinking. Critical bioethicists offered analyses of the arguments presented and the moral and political theories that could be used as the basis of good and acceptable decisions. (shrink)
