In this article, I shall contend that Rawlsian public reason liberalism (PRL) is in tension with non-anthropocentric environmentalism. I will argue that many reasonable citizens reject non-anthropocentric values, and PRL cannot allow them to be used as the justification for ecological policies. I will analyse attempts to argue that PRL can incorporate non-anthropocentric ideas. I shall consider the view, deployed by theorists such as Derek Bell and Mark A. Michael, that PRL can make a distinction between constitutional essentials and non-essentials, (...) and therefore ecocentric values can be employed when only non-essentials are at stake. I will also consider Simon Hailwood’s argument that PRL can incorporate concern for nature based on its ‘otherness’. I shall conclude that both positions fail to rebut the claim that PRL excludes non-anthropocentric viewpoints. I will consider the question of whether PRL’s exclusion of non-anthropocentric ethics is a problem, and I shall show that appealing to purely anthropocentric arguments leads to a variety of unpalatable conclusions. I will suggest that comprehensive liberalism can include non-anthropocentric concerns, and hence is superior from an environmental perspective. (shrink)

In this article, we claim that recent developments in climate science and renewable energy should prompt a reframing of debates surrounding climate change mitigation. Taken together, we argue that these developments suggest (1) global climate collapse in this century is a non-negligible risk, (2) mitigation offers substantial benefits to current generations, and (3) mitigation by some can generate social tipping dynamics that could ultimately make renewables cheaper than fossil fuels. We explain how these claims undermine familiar framings of climate change, (...) wherein mitigation is understood as self-sacrifice that individuals and governments must be morally persuaded or incentivized to undertake.

With respect to climate change, what is wanted is an account that morally condemns the production of ‘luxury’ greenhouse gas emissions (e.g., joyriding in an SUV), but not ‘subsistence’ emissions (e.g., cooking meals). Now, our individual greenhouse gas emissions either cause harm, or they do not—and those who condemn the production of luxury emissions generally stake their position on the grounds that they do cause harm. Meanwhile, those seeking to defend the moral permissibility of luxury emissions generally do so by (...) arguing that our individual emissions do not cause harm. Here, I argue that, if our individual emissions do cause harm, then this entails too much. For, it entails not only that our luxury emissions are morally impermissible, but that our subsistence emissions are too. This is an undesirable result. Therefore, I propose that we embrace our other option. Namely, I propose that we accept that our individual emissions do not cause harm; or at least, that they make no perceptible difference with respect to the harms associated with climate change. The result of this admission is not as bad as you might think. For, I argue, even if we are individually causally impotent with respect to the harms of climate change, there remains a plausible route toward the moral condemnation of our individual luxury emissions—contrary to what others have argued. What is more, only by accepting our individual causal impotence can we successfully ground the permissibility of our individual subsistence emissions. (shrink)

In this article, we defend two claims about the precautionary principle. The first is that there is no ‘core’ precautionary principle that unifies all its different versions. It is more plausible to think of the different versions as being related to each other by way of family resemblances. So although precautionary principle x may have much in common with precautionary principle y, and y with z, there is no set of necessary and sufficient conditions that unify all versions of the (...) principle. Our second claim is that it is sometimes appropriate to think of the precautionary principle as a midlevel principle in the sense proposed by Beauchamp and Childress in their Principles of Biomedical Ethics, i.e. as a non-rigid moral principle. We argue that if the precautionary principle is conceived as a non-rigid principle that needs to be balanced against other principles before a moral verdict can be reached, then this enables us to address some standard objections to the principle.

This open access book provides the first explicit case study for an application of the method of reflective equilibrium (RE), using it to develop and defend a precautionary principle. It thereby makes an important and original contribution to questions of philosophical method and methodology. The book shows step-by-step how RE is applied, and develops a methodological framework which will be useful for everyone who wishes to use reflective equilibrium. With respect to precautionary principles, the book demonstrates how a rights-based precautionary (...) principle can be constructed and defended. The case study succeeds in demonstrating that RE can be successfully applied and puts real constraints on the justification process. This is all the more remarkable as the case study was designed as an open-ended process, without presupposing any specific results. This book will be highly relevant both to people interested in philosophical methodology and epistemology, as well as to researchers who are interested in using philosophical methods and tools and applying them to practical problems.

A notable feature of recent philosophical work on climate ethics is that it makes practically no reference to ‘traditional’ environmental philosophy. There is some irony in this, since environmental ethics arose as part of a broader movement within philosophy, starting in the 1960s, aimed at developing different fields of applied philosophy, in order to show how everyday practice could be enriched through philosophical reflection and analysis. The major goal of this paper is to explain why this branch of practical ethics (...) has, for the most part, failed the test of practicability when it comes to formulating a response to global climate change. The central problem is that debates in environmental philosophy became absorbed by a set of metaphysical questions about the nature of value. The result has been a field dominated by views that provide unsuitable foundations for the development of public policy. (shrink)

The precautionary principle has been widely discussed in the academic, legal, and policy arenas. This paper argues, however, that there is no single precautionary principle and we should stop referring to ?the? precautionary principle. Instead, we should talk about ?precaution? and ?precautionary approaches? more generally and identify and defend distinct precautionary principles of limited scope. Drawing on the vast literature on ?the? precautionary principle, this paper further argues that the challenges of decision making under conditions of uncertainty necessitate taking a (...) precautionary approach to decision making that will enable us to understand what particular precautionary principles require of us on a case-by-case basis.

The Intergovernmental Panel for Climate Change has over the past decade repeatedly warned that we are heading towards inevitable and irreversible climate change, which will negatively affect the lives, livelihoods, and well-being of millions of people around the world, both at present and in the future. In fact, many people, especially vulnerable and marginalized communities in low- and middle-income countries, already live with the effects of climate change in their daily lives. While adaptation – along with mitigation and compensation for (...) loss and damage as a consequence of climate change – was identified as the central pillars of a just climate policy in the Paris Agreement it is unclear whether this entails a right to adaptation – that some people are owed, as a matter of justice, to have the ability to adapt to climate change – and, if so, what such a right would look like. In this paper, I argue that individuals and communities who are or will be negatively affected by climate change through no fault of their own should have the right to adaptation. I argue that the right to adaptation should be specified through four questions: (i) who has a right to adaptation; (ii) what is it a right to; (iii) how much is it a right to; and (iv) who has the duty to uphold the right to adaptation?

This article argues that parents have a special, shared duty to organize for collective action on climate change mitigation and adaptation, but not for the reason one might assume. The apparently obvious reason is that climate change threatens life, health and community for the next generation, and parents have a special duty to their children to protect their basic human interests. This argument fails because many parents could protect their children from these central harms without taking more general action to (...) combat climate change, let alone to mitigate it. Instead, subtler reasons are advanced, drawing on children’s relational interests or on their interests as moral agents. It is argued that parents owe it to their children to combat climate change because of the indirect impact on current children of serious threats to their children and grandchildren, and of being required to live in a radically unjust world. It is further argued that parents may owe it directly to their more distant descendants to mitigate climate change because of the role current parents played in bringing them into the world.

According to John Rawls, the methods and conclusions of science—when these are non-controversial—constitute public reasons. However, several objections have been raised against this view. This paper focuses on two objections. On the one hand, the associational objection states that scientific reasons are the reasons of the scientific community, and thus paradigmatically non-public in the Rawlsian sense. On the other hand, the controversiality objection states that the non-controversiality requirement rules out their public character when scientific postulates are resisted by a significant (...) portion of the citizenry. The paper replies that both objections miss their mark. To the associational objection, it replies that the relevant test for a reason to be public is whether the reasons have been construed under the rules and constrains of a public frame of thought. Insofar as scientific methods and conclusions correspond to the principles of reasoning and rules of evidence that liberals understand as public, their associational origin is secondary. To the controversiality objection, it replies that the standard for a scientific argument to be regarded as non-controversial should refer to its degree of intra-scientific consensus, since ordinary citizens accept or reject scientific pronouncements conditioned to their particular comprehensive views. Nonetheless, a wide extra-scientific agreement on the epistemic virtues of the scientific method will be needed. The paper concludes that there is a good case to think about scientific reasons as public to the extent that scientific reasoning is a mode of inquiry that mirrors a central aspiration of Rawlsian political liberalism: having a public way of thought and an impersonal standpoint to adjudicate between competing claims.

The status of scientific knowledge in political liberalism is controversial. Although Rawls argued that the noncontroversial methods and conclusions of science belong to the kind of reasons that citizens can legitimately call forth in public deliberation, critics have observed that the complexity and elaborateness of scientific arguments drive them away from the spirit of public reason, i.e., that which should reflect judgments that are the product of general beliefs and forms of reasoning found in common sense. In other words, scientific (...) claims remain as inaccessible as esoteric or religious reasons. This paper contends that this objection can be met by introducing a crucial assumption, drawn from W. V. O. Quine and the ‘naturalized epistemology’ tradition: that scientific reasoning and everyday reasoning are not two different epistemic categories but rather form a continuum. The former is just a filtered or refined version of the latter. Accordingly, evidence-based scientific reasoning is common to all citizens, regardless of their actual acceptance of specific scientific claims. Following the Quinean Assumption, political liberals may argue that, unlike religious or esoteric sources of knowledge, scientific reasoning is the expression of a cognitive operation that is fundamentally shared across comprehensive doctrines and politically reasonable individuals.

In the Anthropocene, human beings are capable of bringing about globally catastrophic outcomes that could damage conditions for present and future human life on Earth in unprecedented ways. This paper argues that the scale and severity of these dangers justifies a new international criminal offence of ‘postericide’ that would protect present and future people against wrongfully created dangers of near extinction. Postericide is committed by intentional or reckless systematic conduct that is fit to bring about near human extinction. The paper (...) argues that a proper understanding of the moral imperatives embodied in international criminal law shows that it ought to be expanded to incorporate a new law of postericide.

I defend the claim that life-suspending technologies can constitute a catastrophic and existential security factor for risks structurally similar to those related to climate change. The gist of the argument is that, under certain conditions, life-suspending technologies such as cryonics can provide self-interested actors with incentives to efficiently tackle such risks—in particular, they provide reasons to overcome certain manifestations of generational egoism, a risk factor of several catastrophic and existential risks. Provided we have reasons to decrease catastrophic and existential risks (...) such as climate change, we also have a (defeasible) reason for investing in developing and making life-suspending technologies (more) widespread.
