Recent results from the neurosciences demonstrate that pleasure and pain are not two symmetrical poles of a single scale of experience but in fact two different types of experiences altogether, with dramatically different contributions to well-being. These differences between pleasure and pain and the general finding that “the bad is stronger than the good” have important implications for our treatment of nonhuman animals. In particular, whereas animal experimentation that causes suffering might be justified if it leads to the prevention of (...) more suffering, it can never by justified merely by leading to increased levels of happiness.

There are roughly two philosophical literatures on “happiness,” each corresponding to a different sense of the term. One uses ‘happiness’ as a value term, roughly synonymous with well-being or flourishing. The other body of work uses the word as a purely descriptive psychological term, akin to ‘depression’ or ‘tranquility’. An important project in the philosophy of happiness is simply getting clear on what various writers are talking about: what are the important meanings of the term and how do they connect? (...) While the “well-being” sense of happiness receives significant attention in the contemporary literature on well-being, the psychological notion is undergoing a revival as a major focus of philosophical inquiry, following on recent developments in the science of happiness. This entry focuses on the psychological sense of happiness (for the well-being notion, see the entry on well-being). The main accounts of happiness in this sense are hedonism, the life satisfaction theory, and the emotional state theory. Leaving verbal questions behind, we find that happiness in the psychological sense has always been an important concern of philosophers. Yet the significance of happiness for a good life has been hotly disputed in recent decades. Further questions of contemporary interest concern the relation between the philosophy and science of happiness, as well as the role of happiness in social and political decision-making. (shrink)

It may even be held that [the intellect] is the true self of each, inasmuch as it is the dominant and better part; and therefore it would be a strange thing if a man should choose to live not his own life but the life of some other than himself. Moreover . . . that which is best and most pleasant for each creature is that which is proper to the nature of each; accordingly the life of the intellect is (...) the best and the pleasantest life for man, inasmuch as the intellect more than anything else is man.

In Reasons and Persons, Derek Parfit cannot find a theory of well-being that solves the Non-Identity Problem, the Repugnant Conclusion, the Absurd Conclusion, and all forms of the Mere Addition Paradox. I describe a “Quasi-Maximizing” theory that solves them. This theory includes (i) the denial that being better than is transitive and (ii) the “Conflation Principle,” according to which alternative B is hedonically better than alternative C if it would be better for someone to have all the B-experiences. (i) entails (...) that Quasi-Maximization is not a maximizing theory, but (ii) ensures that its evaluations will often coincide with such theories. (shrink)

The psychological condition of being happy is best understood as a matter of a person’s emotional condition. I elucidate the notion of an emotional condition by introducing two distinctions concerning affect, and argue that this “emotional state” view is probably superior on intuitive and substantive grounds to theories that identify happiness with pleasure or life satisfaction. Life satisfaction views, for example, appear to have deflationary consequences for happiness’ value. This would make happiness an unpromising candidate for the central element in (...) a theory of well-being, as it is in L. W. Sumner’s work. Yet on an emotional state conception, happiness may prove to be a key constituent of well-being. The emotional state view also makes happiness less vulnerable to common doubts about the importance of happiness, and indicates that mood states are more important for well-being than is generally recognized.

Invertebrate animals are usually seen as a kind of “aliens” which do not deserve any moral consideration. However, there is a growing amount of evidenceindicating that many of them do have the capacity to experience pain. The samecriteria that are usually applied in order to infer that vertebrates are sentient beings (behavioral response, learning capacity, memory, a certain specific neurophysiological structure…) lead to the idea that many invertebrates aresentient as well. Therefore, under the skeptical premise that we have no directevidence (...) of the experience of pain in vertebrates, we are forced to hold that itexists in both vertebrates and invertebrates.

In this paper, I show that David Benatar’s asymmetry argument for anti-natalism leads to a dilemma. In Chapter 2 of his book Better Never to Have Been, Benatar claims that there is an axiological asymmetry between harms and benefits that explains four prevalent asymmetries. Based on the axiological asymmetry, he defends the anti-natalist conclusion that we should not have children. The four prevalent asymmetries to be explained are moral duties, reasons, attitudes, or feelings concerning life as a whole. However, Benatar (...) explains them by applying the axiological asymmetry to parts of life, such as pains and pleasures. I find a serious gap here. While two ways are available to bridge this gap, a dilemma arises from Benatar’s asymmetry argument. The axiological asymmetry is not supported because it cannot explain the four prevalent asymmetries, or else it cannot lead to the anti-natalist conclusion. A number of philosophers have already criticized Benatar’s asymmetry argument, mainly questioning its assumptions. In this paper, I contend that there is no good reason to agree with his argument even if all its explicit assumptions are accepted. (shrink)

Purpose This paper aims to formalize long-term trajectories of human civilization as a scientific and ethical field of study. The long-term trajectory of human civilization can be defined as the path that human civilization takes during the entire future time period in which human civilization could continue to exist. -/- Design/methodology/approach This paper focuses on four types of trajectories: status quo trajectories, in which human civilization persists in a state broadly similar to its current state into the distant future; catastrophe (...) trajectories, in which one or more events cause significant harm to human civilization; technological transformation trajectories, in which radical technological breakthroughs put human civilization on a fundamentally different course; and astronomical trajectories, in which human civilization expands beyond its home planet and into the accessible portions of the cosmos. -/- Findings Status quo trajectories appear unlikely to persist into the distant future, especially in light of long-term astronomical processes. Several catastrophe, technological transformation and astronomical trajectories appear possible. -/- Originality/value Some current actions may be able to affect the long-term trajectory. Whether these actions should be pursued depends on a mix of empirical and ethical factors. For some ethical frameworks, these actions may be especially important to pursue. (shrink)

The most common argument against negative utilitarianism is the world destruction argument, according to which negative utilitarianism implies that if someone could kill everyone or destroy the world, it would be her duty to do so. Those making the argument often endorse some other form of consequentialism, usually traditional utilitarianism. It has been assumed that negative utilitarianism is less plausible than such other theories partly because of the world destruction argument. So, it is thought, someone who finds theories in the (...) spirit of utilitarianism attractive should not go for negative utilitarianism, but should instead pick traditional utilitarianism or some other similar theory such as prioritarianism. I argue that this is a mistake. The world destruction argument is not a reason to reject negative utilitarianism in favour of these other forms of consequentialism, because there are similar arguments against such theories that are at least as persuasive as the world destruction argument is against negative utilitarianism.

Values are incommensurable when they cannot be measured on a single cardinal scale. Many philosophers suggest that incommensurability can help us solve the problems of population ethics. I agree. But some philosophers claim that populations bear incommensurable values merely because they contain different numbers of people, perhaps within some range. I argue that mere differences in how many people exist, even within some range, do not suffice for incommensurability. I argue that the intuitive neutrality of creating happy people is better (...) captured by a version of average utilitarianism. But this view is problematic. So I suggest a version of total utilitarianism that avoids the repugnant conclusion by appealing to incommensurable dimensions of wellbeing. (shrink)

For many philosophers working in the area of Population Ethics, it seems that either they have to confront the Repugnant Conclusion , or they have to confront the Non-Identity Problem . To them it seems there is no escape, they either have to face one problem or the other. However, there is a way around this, allowing us to escape the Repugnant Conclusion, by using what I will call Negative Average Preference Utilitarianism – which though similar to anti-frustrationism, has some (...) important differences in practice. Current “positive” forms of utilitarianism have struggled to deal with the Repugnant Conclusion, as their theory actually entails this conclusion; however, it seems that a form of Negative Average Preference Utilitarianism easily escapes this dilemma.

One generally considered plausible way to allocate resources in health care is according to people’s needs. In this paper I focus on a somewhat overlooked issue, that is the conceptual structure of health care needs. It is argued that what conceptual understanding of needs one has is decisive in the assessment of what qualifies as a health care need and what does not. The aim for this paper is a clarification of the concept of health care need with a starting (...) point in the general philosophical discussion about needs. I outline three approaches to the concept of need and argue that they all share the same conceptual underpinnings. The concept of need is then analyzed in terms of a subject x needing some object y in order to achieve some goal z. I then discuss the relevant features of the object y and the goal z which make a given need qualify as a health care need and not just a need for anything. (shrink)

Standard, familiar models portray harms and benefits as symmetrical. Usually, harm is portrayed as involving a worsening of one's situation, and benefits as involving an improvement. Yet morally, the aversion, prevention, and relief of harms seem, at least presumptively, to matter more than the provision, protection, and maintenance of comparable and often greater benefits. Standard models of harms and benefits have difficulty acknowledging this priority, much less explaining it. They also fail to identify harm accurately and reliably. In this paper, (...) I develop these problems, argue that we should reconsider our commitment to the standard models, and then merely gesture at the direction in which we might locate a superior approach, one that better accounts for the moral significance of harm and its relation to autonomy rights.

There are several reasons to believe that there is a predominance of suffering over wellbeing in nature. The difference grows exponentially when the suffering of invertebrates is taken into consideration. Given the relevance of the experience of pain when it comes to attributing moral considerability to an individual, the seriousness and implications of the above statements are significant due to the need to reconcile the interests of an enormous number of individuals who experience pain to some degree. Depending on the (...) species and the ecosystem, there are variations that must be kept in mind with the aim of reducing the existing amount of suffering. (shrink)

This paper argues against hedonistic theories of happiness. First, hedonism is too inclusive: many pleasures cannot plausibly be construed as constitutive of happiness. Second, any credible theory must count either attitudes of life satisfaction, affective states such as mood, or both as constituents of happiness; yet neither sort of state reduces to pleasure. Hedonism errs in its attempt to reduce happiness, which is at least partly dispositional, to purely episodic experiential states. The dispositionality of happiness also undermines weakened nonreductive forms (...) of hedonism, as some happiness-constitutive states are not pleasures in any sense. Moreover, these states can apparently fail to exhibit the usual hedonic properties; sadness, for instance, can sometimes be pleasant. Finally, the nonhedonistic accounts are adequate if not superior on grounds of practical and theoretical utility, quite apart from their superior conformity to the folk notion of happiness. (shrink)

This paper examines a dilemma in reproductive and population ethics that can illuminate broader questions in axiology and normative ethics. This dilemma emerges because most people have conflicting intuitions concerning whether the interests of non-existent beings can outweigh the interests of existing beings when those merely potential beings are expected to have overall net-good or overall net-bad lives. The paper claims that the standard approach to this issue, in terms of exemplifying the conflict between Narrow Person-Affecting Views and Impersonal Views, (...) is not correct. It argues that, instead, we can approach the issue through the distinction between Symmetrical and Asymmetrical Views about the relative importance of positive and negative value. The paper also claims that Asymmetrical Views provide the most intuitively satisfactory solution to the dilemma and can in addition be defended independently on further grounds. Keywords: person-affecting views, impersonal views, symmetry, asymmetry. (shrink)

It is often said that while we have a strong reason not to create someone who will be badly off, we have no strong reason for creating someone who will be well off. In this paper I argue that this asymmetry is incompatible with a plausible principle of independence of irrelevant alternatives, and that a more general asymmetry between harming and benefiting is difficult to defend. I then argue that, contrary to what many have claimed, it is possible to harm (...) or benefit someone by bringing her into existence. (shrink)

I defend a methodology for theorizing about happiness. I reject three methods: conceptual analysis; scientific naturalism; and the “pure normative adequacy” approach, where the best conception of happiness is the one that best fills a role in moral theory. The concept of happiness is a folk notion employed by laypersons who have various practical interests in the matter, and theories of happiness should respect this fact. I identify four such interests in broad terms and then argue for a set of (...) desiderata that theories of happiness ought to satisfy. The theory of happiness falls within the province of ethics. It should, however, be viewed as autonomous and not merely secondary to moral theory. (shrink)

Even though social engineering has gained a bad reputation, due to new possibilities in the information age, it may be time to reconsider Karl Popper’s conception of “piecemeal social engineering.” Piecemeal social engineering is not only an element within Popper’s open society. It also connects his political philosophy to his philosophy of science and his evolutionary epistemology. Furthermore, it seems to fit well into the search for implementation strategies for policies and social actions in the context of nonideal theory. Nevertheless, (...) this does not necessarily undermine the need for political ideals and first-order principles, which are inhabitants of “World 3.”. (shrink)
