The possibility of enhancing human abilities often raises public concern about equality and social impact. This chapter aims at one particular group of technologies, cognitive enhancement, and one particular fear, that enhancement will create social divisions and possibly expanding inequalities. The chapter argues that cognitive enhancements could offer significant social and economic benefits. The basic forms of internal cognitive enhancement technologies foreseen today are pharmacological modifications, genetic interventions, transcranial magnetic stimulation, and neural implants. Cognitive enhancements can influence the economy through (...) reduction of losses, individual economic benefits, and society‐wide benefits. The strongest objection to the introduction of any enhancement technology is that it will create inequality, injustice, and unfairness. While there are clear economic and social benefits to cognitive enhancement, there exist anumber of obstacles to its development and use. One obstacle is the present system for licensing drugs and medical treatments. (shrink)

A controversial scientific vision predicts a time in which humans and machines will merge and create a new form of non-biological intelligence, explaining how the occurrence will solve such issues as pollution, hunger, and aging.

Most people, including philosophers, tend to classify human motives as falling into one of two categories: the egoistic or the altruistic, the self-interested or the moral. According to Susan Wolf, however, much of what motivates us does not comfortably fit into this scheme. Often we act neither for our own sake nor out of duty or an impersonal concern for the world. Rather, we act out of love for objects that we rightly perceive as worthy of love--and it is these (...) actions that give meaning to our lives. Wolf makes a compelling case that, along with happiness and morality, this kind of meaningfulness constitutes a distinctive dimension of a good life. Written in a lively and engaging style, and full of provocative examples, Meaning in Life and Why It Matters is a profound and original reflection on a subject of permanent human concern. (shrink)

Naturalist theories of the meaning of life are sometimes criticised for not setting the bar high enough for what counts as a meaningful life. Tolstoy’s version of this criticism is that Naturalist theories do not describe really meaningful lives because they do not require that we connect our finite lives with the infinite. Another criticism of Naturalist theories is that they cannot adequately resolve the Absurd—the vast difference between how meaningful our actions and lives appear from subjective and objective viewpoints. (...) This article proposes a novel view, Optimistic Naturalism, in order to refute these criticisms. Optimistic Naturalism is the view that scientific and technological advancement might allow us to lead Truly Meaningful lives in a purely physical universe by enabling our actions, which we find meaningful partly because they might have particular infinite consequences, to actually have infinite consequences for life. The central tenets of Optimistic Naturalism are Infinite Consequence and Scientific Optimism. By explaining how the correct connection of the subjective and objective meaning of actions can result in True Meaning, Infinite Consequence provides a theoretical blueprint for resolving the Absurd. Scientific Optimism provides reason to think that it is possible to follow that blueprint in a purely physical universe. Therefore, when taken together, these two principles provide relatively plausible reasons to think that at least one kind of Naturalist theory can connect the finite with the infinite in a meaningful way and resolve the Absurd.

I defend normative externalism from the objection that it cannot account for the wrongfulness of moral recklessness. The defence is fairly simple—there is no wrong of moral recklessness. There is an intuitive argument by analogy that there should be a wrong of moral recklessness, and the bulk of the paper consists of a response to this analogy. A central part of my response is that if people were motivated to avoid moral recklessness, they would have to have an unpleasant sort (...) of motivation, what Michael Smith calls “moral fetishism”.

The ancient philosophical school of Epicureanism tried to argue that death is "nothing to us." Were they right? James Warren provides a comprehensive study and articulation of the interlocking arguments against the fear of death found not only in the writings of Epicurus himself, but also in Lucretius' poem De rerum natura and in Philodemus' work De morte. These arguments are central to the Epicurean project of providing ataraxia (freedom from anxiety) and therefore central to an understanding of Epicureanism as (...) a whole. They also offer significant resources for modern discussions of the value of death--one which stands at the intersection of metaphysics and ethics. If death is the end of the subject, and the subject can not be benefited nor harmed after death, is it reasonable nevertheless to fear the ceasing-to-be? If the Epicureans are not right to claim that the dead can neither be benefited nor harmed, what alternative models might be offered for understanding the harm done by death and do these alternatives suffer from any further difficulties? The discussion involves consideration of both ethical and metaphysical topics since it requires analysis not only of the nature of a good life but also the nature of personal identity and time. A number of modern philosophers have offered criticisms or defences of the Epicureans' views. Warren explores and evaluates these in the light of a systematic and detailed study of the precise form and intention of the Epicureans' original arguments. Warren argues that the Epicureans also were interested in showing that mortality is not to be regretted and that premature death is not to be feared. Their arguments for these conclusions are to be found in their positive conception of the nature of a good and complete life, which divorce the completeness of a life as far as possible from considerations of its duration. Later chapters investigate the nature of a life lived without the fear of death and pose serious problems for the Epicureans being able to allow any concern for the post mortem future and being able to offer a positive reason for prolonging a life which is already complete in their terms.

I defend the theory that one's life is meaningful to the extent that one promotes the good. Call this the good cause account (GCA) of the meaning of life. It holds that the good effects that count towards the meaning of one's life need not be intentional. Nor must one be aware of the effects. Nor does it matter whether the same good would have resulted if one had not existed. What matters is that one is causally responsible for the (...) good. I argue that the best theory of the meaning of life should clearly distinguish between subjective fulfillment and objective meaningfulness. The GCA respects the distinction. And it is superior to its leading rivals in the recent literature, most notably those of Erik Wielenberg and Susan Wolf. (shrink)

Human beings are a marvel of evolved complexity. Such systems can be difficult to enhance. When we manipulate complex evolved systems, which are poorly understood, our interventions often fail or backfire. It can appear as if there is a “wisdom of nature” which we ignore at our peril. Sometimes the belief in nature’s wisdom—and corresponding doubts about the prudence of tampering with nature, especially human nature—manifests as diffusely moral objections against enhancement. Such objections may be expressed as intuitions about the (...) superiority of the natural or the troublesomeness of hubris or as an evaluative bias in favor of the status quo. This chapter explores the extent to which such prudence-derived anti-enhancement sentiments are justified. We develop a heuristic, inspired by the field of evolutionary medicine, for identifying promising human enhancement interventions. The heuristic incorporates the grains of truth contained in “nature knows best” attitudes while providing criteria for the special cases where we have reason to believe that it is feasible for us to improve on nature.

It is natural for those with permissive attitudes toward abortion to suppose that, if they have examined all of the arguments they know against abortion and have concluded that they fail, their moral deliberations are at an end. Surprisingly, this is not the case, as I argue. This is because the mere risk that one of those arguments succeeds can generate a moral reason that counts against the act. If this is so, then liberals may be mistaken about the morality (...) of abortion. However, conservatives who claim that considerations of risk rule out abortion in general are mistaken as well. Instead, risk-based considerations generate an important but not necessarily decisive reason to avoid abortion. The more general issue that emerges is how to accommodate fallibilism about practical judgment in our decision-making. (shrink)

Three of the great sources of meaning in life are the good, the true, and the beautiful, and I aim to make headway on the grand Enlightenment project of ascertaining what, if anything, they have in common. Concretely, if we take a (stereotypical) Mother Teresa, Mandela, Darwin, Einstein, Dostoyevsky, and Picasso, what might they share that makes it apt to deem their lives to have truly mattered? I provide reason to doubt two influential answers, noting a common flaw that supernaturalism (...) and consequentialism share. I instead develop their most plausible rival, a naturalist and non-consequentialist account of what enables moral achievement, intellectual reflection, and aesthetic creation to confer great meaning on a person's life, namely, the idea that they do so insofar as a person transcends an aspect of herself in some substantial way. I criticize several self-transcendence theories that contemporary philosophers have advanced, before presenting a new self-transcendence view and defending it as the most promising. (shrink)

We are often uncertain how to behave morally in complex situations. In this controversial study, Ted Lockhart contends that moral philosophy has failed to address how we make such moral decisions. Adapting decision theory to the task of decision-making under moral uncertainly, he proposes that we should not always act how we feel we ought to act, and that sometimes we should act against what we feel to be morally right. Lockhart also discusses abortion extensively and proposes new ways to (...) deal with the ethical and moral issues which surround it. (shrink)

In this book, David Benatar argues that every person is severely harmed by being brought into existence, and that in bringing any person into existence one impermissibly harms that person. His conclusion is not merely that by bringing a person into existence, one harms him. That claim is compatible with the claim that by bringing a person into existence, one also greatly benefits him, and even with the claim that one never impermissibly harms someone by bringing him into existence. His (...) conclusion is much more radical. (shrink)

This paper takes on several distinct but related tasks. First, I present and discuss what I will call the “Ignorance Thesis,” which states that whenever an agent acts from ignorance, whether factual or moral, she is culpable for the act only if she is culpable for the ignorance from which she acts. Second, I offer a counterexample to the Ignorance Thesis, an example that applies most directly to the part I call the “Moral Ignorance Thesis.” Third, I argue for a (...) principle—Don’t Know, Don’t Kill—that supports the view that the purported counterexample actually is a counterexample. Finally, I suggest that my arguments in this direction can supply a novel sort of argument against many instances of killing and eating certain sorts of animals. (shrink)

Might it be morally wrong to procreate? David Benatar answers affirmatively in Better Never to Have Been , arguing that coming into existence is always a great harm. I counter this view in several ways. First, I argue against Benatar’s asserted asymmetry between harm and benefit—which would support the claim that any amount of harm in a human life would make it not worth starting—while questioning the significance of his distinction between a life worth starting and one worth continuing. I (...) further contend that his understanding of hedonism and desire-fulfillment theories distorts their implications for the quality of human life; as for objective-list theories, I rebut his critique of their human-centered basis of evaluation. Notwithstanding this multi-tiered challenge to Benatar’s reasoning, I conclude with praise for his work and the intellectual virtues it embodies. (shrink)

It is widely recognized that lives and activities can be meaningful or meaningless, but few have appreciated that they can also be anti-meaningful. Anti-meaning is the polar opposite of meaning. Our purpose in this essay is to examine the nature and importance of this new and unfamiliar topic. In the first part, we sketch four theories of anti-meaning that correspond to leading theories of meaning. In the second part, we argue that anti-meaning has significance not only for our attempts to (...) theorize about meaning in life, but also for our ability to lead meaningful lives in the modern world.

The rapid developments in technologies -- especially computing and the advent of many 'smart' devices, as well as rapid and perpetual communication via the Internet -- has led to a frequently voiced view which Nicholas Agar describes as 'radical optimism'. Radical optimists claim that accelerating technical progress will soon end poverty, disease, and ignorance, and improve our happiness and well-being. Agar disputes the claim that technological progress will automatically produce great improvements in subjective well-being. He argues that radical optimism 'assigns (...) to technological progress an undeserved pre-eminence among all the goals pursued by our civilization'. Instead, Agar uses the most recent psychological studies about human perceptions of well-being to create a realistic model of the impact technology will have. Although he accepts that technological advance does produce benefits, he insists that these are significantly less than those proposed by the radical optimists, and aspects of such progress can also pose a threat to values such as social justice and our relationship with nature, while problems such as poverty cannot be understood in technological terms. He concludes by arguing that a more realistic assessment of the benefits that technological advance can bring will allow us to better manage its risks in future. (shrink)

We normally take it for granted that other people will live on after we ourselves have died. Even if we do not believe in a personal afterlife in which we survive our own deaths, we assume that there will be a "collective afterlife" in which humanity survives long after we are gone. Samuel Scheffler maintains that this assumption plays a surprising - indeed astonishing - role in our lives.

In contemporary Western society, people are more often called upon to justify the choice not to have children than they are to supply reasons for having them. In this book, Christine Overall maintains that the burden of proof should be reversed: that the choice to have children calls for more careful justification and reasoning than the choice not to. Arguing that the choice to have children is not just a prudential or pragmatic decision but one with ethical repercussions, Overall offers (...) a wide-ranging exploration of how we might think systematically and deeply about this fundamental aspect of human life. Writing from a feminist perspective, she also acknowledges the inevitably gendered nature of the decision; the choice has different meanings, implications, and risks for women than it has for men. After considering a series of ethical approaches to procreation, and finding them inadequate or incomplete, Overall offers instead a novel argument. Exploring the nature of the biological parent-child relationship -- which is not only genetic but also psychological, physical, intellectual, and moral -- she argues that the formation of that relationship is the best possible reason for choosing to have a child.

Better Never to Have Been argues for a number of related, highly provocative, views: (1) Coming into existence is always a serious harm. (2) It is always wrong to have children. (3) It is wrong not to abort fetuses at the earlier stages of gestation. (4) It would be better if, as a result of there being no new people, humanity became extinct. These views may sound unbelievable--but anyone who reads Benatar will be obliged to take them seriously.

This chapter critically explores contemporary philosophical understandings of whether meaning in life might depend on the presence or absence of an afterlife. After distinguishing various kinds of afterlife, it focuses most on the potential relevance of an eternal one, and considers at length the extreme but common views amongst philosophers that an eternal afterlife would be either necessary for a meaningful life or, conversely, sufficient for a meaningless one. It concludes by considering the plausibility of a more moderate view, that (...) an eternal afterlife could substantially enhance the meaning of our lives, even if they would not be meaningless without it. The aim of the chapter is not to defend some overall thesis about these positions, but rather to acquaint the reader with recent English-speaking philosophical discussions of them. (shrink)

Theists are inclined to assert that human life would be meaningless if there was no personal immortality and God did not exist. The present paper aims to evaluate the truth of this claim. The author first explores the conception of meaning that is at the roots of the theistic position. After pointing out some difficulties with it, the author shows that, on a plausible alternative interpretation of what it is for an activity to have meaning, human life would fully qualify (...) as meaningful even if it were not inscribed in a universal divine plan.
