Common sense morality and legislations around the world ascribe normative relevance to biological connections between parents and children. Procreators who meet a modest standard of parental competence are believed to have a right to rear the children they brought into the world. I explore various attempts to justify this belief and find most of these attempts lacking. I distinguish between two kinds of biological connections between parents and children: the genetic link and the gestational link. I argue that the second (...) can better justify a right to rear.

The debate on personal persistence has been characterized by a dichotomy which is due to its still Cartesian framwork: On the one side we find proponents of psychological continuity who connect, in Locke’s tradition, the persistence of the person with the constancy of the first-person perspective in retrospection. On the other side, proponents of a biological approach take diachronic identity to consist in the continuity of the organism as the carrier of personal existence from a third-person-perspective. Thus, what accounts for (...) someone’s persistence over time, is the continuity of his mind on the one hand, and the continuity of his body on the other. In contrast to those views, the paper intends to show that bodily existence represents the basis of selfhood across time, both as the continuity of the experiential self and as the continuity of the autopoietic organism. On the one hand, the lived body conveys a continuity of the self from a first-person perspective, namely a pre-reflective feeling of sameness or a felt constancy of subjectivity. Moreover, an analysis of awakening and sleep shows that there is a continuous transition from full wakefulness to periods of deep sleep which may thus not be regarded as a complete interruption of subjective experience. On the other hand, this constancy converges with the continuity of the organismic life process as conceived from a third-person perspective. Thus, the experiential self of bodily subjectivity and the autopoietic self of the living organism should be regarded as two aspects of one and the same life process. Finally, the lived body also exhibits a specific form of memory that results from the continual embodiment of existence: it consists of all the affinities, capacities and experiences, which a person has acquired throughout his life. Thus, it provides a continuity of self that must not be actively produced through remembering, but rather integrates the person’s entire past in his present being and potentiality. (shrink)

Theories of personal identity in the tradition of John Locke and Derek Parfit emphasize the importance of psychological continuity and the abilities to think, to remember and to make rational choices as a basic criterion for personhood. As a consequence, persons with severe dementia are threatened to lose the status of persons. Such concepts, however, are situated within a dualistic framework, in which the body is regarded as a mere vehicle of the person, or a carrier of the brain as (...) the organ of mental faculties. Based on the phenomenology of embodiment, this paper elaborates a different approach to personal identity in dementia. In this perspective, selfhood is primarily constituted by pre-reflective self-awareness and the body memory of an individual, which consists in the embodiment and enactment of familiar habits, practices and preferences. After describing the different types of body memory, the paper develops a phenomenology of dementia as a loss of reflexivity and meta-perspective. This is contrasted with the preservation of individual forms of body memory even in the later stages of the illness. The ethical consequences of an embodied approach to dementia are outlined. A final look is given to narrativistic and constructionist concepts of the self in dementia. (shrink)

Temporal nihilism is the view that our lives won’t matter after we die. According to the standard interpretation, this is because our lives won’t make a permanent difference. Many who consider the view thus reject it by denying that our lives need to have an eternal impact. However, in this paper, I develop a different formulation of temporal nihilism revolving around the persistence of personal value itself. According to this stronger version, we do not have personal value after death, so (...) our past life no longer has wellbeing after we die. The standard objections to the standard interpretation don’t apply to this more nihilistic nihilism. I offer a new response according to which personal value persists after death because the person continues to exist. (shrink)

A central claim in abortion ethics is what might be called the Harm Claim – the claim that abortion harms the fetus. In this article, we put forward a simple and straightforward reason to reject the Harm Claim. Rather than invoking controversial assumptions about personal identity, or some nonstandard account of harm, as many other critics of the Harm Claim have done, we suggest that the aborted fetus cannot be harmed for the simple reason that it does not occupy any (...) well-being level.

Secular arguments for equal and exclusively human worth generally tend to follow one of two strategies. One, which has recently gained renewed attention because of a novel argument by S. Matthew Liao, aims to directly ground worth in an intrinsic property that all humans have in common, whereas the other concedes that there is no morally relevant intrinsic difference between all humans and all other animals, and instead appeals to the membership of all humans in a special kind. In this (...) article, I argue that both strategies necessitate drawing a line that is both arbitrary and implausibly opens a moral gulf between individuals whose difference from one another in terms of empirical reality is entirely unremarkable, providing reasons to reject them that go beyond the standard objections in the literature. I conclude that, if all humans are to be included in the community of equals, we must lay to rest the idea that we can do so without also including a wide range of non-human animals. (shrink)

The Procreation Asymmetry holds that we have strong moral reasons not to create miserable people for their own sakes, but no moral reasons to create happy people for their own sakes. To defend this conjunction against an argument that it leads to inconsistency, I show how recognizing ‘creation’ as a temporally extended process allows us to revise the conjuncts in a way that preserves their intuitive force. This defense of the Procreation Asymmetry is preferable to others because it does not (...) require us to take on controversial metaphysical or metaethical commitments – in other words, it has the theoretical virtue of portability.

The paper investigates whether it is plausible to hold the late stage demented criminally responsible for past actions. The concern is based on the fact that policy makers in the United States and in Britain are starting to wonder what to do with prison inmates in the later stages of dementia who do not remember their crimes anymore. The problem has to be expected to become more urgent as the population ages and the number of dementia patients increases. This paper (...) argues that the late-stage demented should not be punished for past crimes. Applicable theories of punishment, especially theories with an appropriate expressivist, or communicative element, fail to justify the imprisonment of the late-stage demented. Further imprisonment would require a capacity for comprehension on the part of the punished, and, under certain narrowly specified conditions, even a capacity to be at least in principle capable of recalling the crime again.

This paper is an exploration of the nature of what is perhaps the most widely recognized justification for inflicting harm on human beings: the appeal to defense (self-defense and other-defense). I develop and defend a rights-based account of the appeal to defense that takes into account whether and to what degree both the aggressor and his potential victim are morally responsible for the relevant threat. However, unlike most extant rights-based accounts, mine is not a forfeiture account. That is, I do (...) not attempt to explain the permissibility of defense in terms of the aggressor’s loss of a right not to be harmed. Instead I appeal directly to the fact that defense in the relevant cases prevents the aggressor from infringing upon the rights of his potential victim. Accordingly, I call my account a “prevention account.”. (shrink)

The concept of “harm” is ubiquitous in moral theorising, and yet remains poorly defined. Bradley suggests that the counterfactual comparative account of harm is the most plausible account currently available, but also argues that it is fatally flawed, since it falters on the omission and pre-emption problems. Hanna attempts to defend the counterfactual comparative account of harm against both problems. In this paper, I argue that Hanna’s defence fails. I also show how his defence highlights the fact that both the (...) omission and the pre-emption problems have the same root cause – the inability of the counterfactual comparative account of harm to allow for our implicit considerations regarding well-being when assessing harm. While its purported neutrality with regard to substantive theories of well-being is one of the reasons that this account is considered to be the most plausible on offer, I will argue that this neutrality is illusory. (shrink)

In recent attempts to define ‘harm’, the most promising approach has often been thought to be the counterfactual comparative account of harm. Nevertheless, this account faces serious difficulties. Moreover, it has been argued that ‘harm’ cannot be defined without reference to a substantive theory of well-being, which is itself a fraught issue. This has led to the call for the concept to simply be dropped from the moral lexicon altogether. I reject this call, arguing that the non-comparative approach to defining (...) harm has not been sufficiently explored. I then develop such an account that avoids the difficulties faced by comparative accounts whilst not presupposing a substantive theory of well-being. I conclude that this definition renders a concept of harm that can be meaningfully employed in our moral discourse. (shrink)

In this paper, I first argue that sometimes freely and knowingly manipulating oneself does not fully preserve moral responsibility – namely, in cases of practically distinct self-manipulation. However, I argue that practically distinct self-manipulation preserves moral responsibility to some extent because such a self-manipulated person is more morally responsibility than an other-manipulated person. This is an important result: manipulating oneself doesn’t always fully preserve one’s moral responsibility for one’s actions. But in what sense is the self-manipulated person more morally responsible? (...) I argue the self-manipulated person is not a fitting target of the reactive attitudes but continues to have wrongdoing-incurred reparative obligations. This explains the intuitive judgement about the self-manipulated person, provides a better explanation of “tracing” cases, and reveals important requirements for a plausible theory of moral responsibility.

This thesis takes up a rights-based perspective to discuss a number of issues related to the problem of permissible harm. It appeals to a person’s capacity to shape her life in accordance with her own ideas of the good to explain why her death can be bad for her, and why each of us should have primary say over what may be done to her. The thesis begins with an investigation of the badness of death for the person who dies. (...) If death is bad for us, this helps explain the wrongness of killing. The thesis defends the deprivation account—i.e. the idea that death is bad for us when and because it deprives us of good life—against two Epicurean challenges. It adds that death is also bad when and because it thwarts our agency. Next, the thesis deals with the logic of our moral rights to non-interference. It proposes a conception of rights according to which the stringency of our rights derives from and is justified by the rational aspect of our human nature. It argues that this conception of moral rights solves the paradox of deontology. While our rights to non-interference are stringent, they are not absolute. The thesis considers two possible exceptions to the general rule that it is impermissible to harm an innocent person against her consent. First, using an actual case from WWII, it investigates the circumstances under which a government may expose some parts of its population to an increased risk of harm in order to decrease the risk to others. Second, it considers the permissibility of self-defence against an innocent threat. It argues that the potential victim of an innocent threat has a justice-based reason to treat her own interests as on a par with those of the threat. (shrink)

Epicurus (in)famously argued that death is not harmful and therefore our standard reactions to it (like deep fear of death and going to great lengths to postpone it) are not rational, inaugurating an ongoing debate about the harm of death. Those who wish to resist this conclusion must identify the harm of death. But not any old harm will do. In order to resist both the claim that death is not harmful and the claim that our standard reactions to it (...) are irrational, we must identify a harm associated with death that rationalizes our standard reactions. We can divide the potential harm properties death might have along two axes: intrinsic/extrinsic and instrumental/final. This gives us four places to search for the harm of death. I argue that it is nowhere to be found. (shrink)

After decades of receiving a lot of attention on the epistemological level, the so-called ‘problem of intuitions’ is now in the center of debates on the metaphilosophical level. One of the reasons for this lies in the unfruitfulness of the epistemological discussions that recently subsided without producing any significant or broadly accepted theory of intuitions. Consequently, the metaphilosophical level of discussion of the ‘problem of intuitions’ inherits the same difficulties of the epistemological level. The significance of Max Deutsch’s book The (...) Myth of the Intuitive is his effort to resolve these problems in a clear and persuasive way. He is not only trying to debunk problems behind the vagueness of the ‘intuition-talk’ by drawing important distinctions that usually go under the radar in the contemporary literature, but also develops his own account of philosophical methodology. In this paper I will present some of his arguments against the traditional view of intuitional methodology, as well as his own solutions to the presented problems. Regardless of Deutsch’s insightful account of the ‘problem of intuitions’, I find that some difficulties in his own proposal are inherited from the unresolved issues of intuitions on the epistemological level.

Florianópolis: NEL/UFSC, 2011. p. 186-201. (Coleção rumos da epistemologia; 11). Através da análise do pensamento de Isaac Newton (1642-1727) encontramos os postulados metafísicos que fundamentam a sua mecânica natural. Ao deduzir causa de efeito, ele acreditava chegar a uma causa primeira de todas as coisas. A essa primeira causa de tudo, onde toda a ordem e leis (...) tiveram início, a qual para ele assume um caráter divino, Newton aponta para um Deus sábio e poderoso e responsável pela ordem inteligente e pela a harmonia das leis físicas e universais de tudo o que existe – Deus como criador e preservador da ordem do universo. Há ainda a analogia do conceito de Deus com o espaço e o tempo, na medida em que ambos comunicam infinitude e onipresença. Por fim, nas considerações finais apontarei a importância de Newton para a metafísica moderna e como os seus estudos contribuíram para uma visão posterior do universo e suas leis e do homem enquanto ser pensante.

When an abortion is performed, someone dies. Are we killing an innocent human person? Widespread disagreement exists. However, it’s not necessary to establish personhood in order to establish the wrongness of abortion: a substantial chance of personhood is enough. We defend The Don’t Risk Homicide Argument: abortions are wrong after 10 weeks gestation because they substantially and unjustifiably risk homicide, the unjust killing of an innocent person. Why 10 weeks? Because the cumulative evidence establishes a substantial chance (a more than (...) 1 in 5 chance) that preborn humans are persons around this stage of development. We submit evidence from our bad track record, widespread disagreement about personhood (after 10 weeks gestation), problems with theories of personhood, the similarity between preborn humans and newborn babies, gestational age miscalculations, and the common intuitive responses of women to their pregnancies and miscarriages. Our argument is cogent because it bypasses the stalemate over preborn personhood and rests on common ground rather than contentious metaphysics. It also strongly suggests that society must do more to protect preborn humans. We discuss its practical implications for fetal pain relief, social policy, and abortion law. (shrink)

The focus of this chapter is public policy and consequentialism, especially issues that arise in connection with the environment – i.e. the natural world, including non-human animals. We integrate some of the existing literature on environmental economics, welfare economics, and policy with the literature on environmental values and philosophy. The emphasis on environmental policy is motivated by the fact that it is arguably the most philosophically interesting and challenging application of consequentialism to policy, as it includes all the challenges of (...) valuing the distribution of human wealth and power, and has the further challenge of putting these consequences on the same scale as consequences for human health, non-human animals, and nature. We suggest that standard methods of (economic) policy analysis provide a good approximation of correct welfarist analysis, except that they must be supplemented with methods for valuing animal wellbeing and tradeoffs with human wellbeing. We then provide the needed methods. (shrink)

Theories of well-being tell us what makes a life good for the one who lives it. But there is more to what makes a life worth living than just well-being. We care about the worth of our lives, and we are right to do so. I defend an objective list theory of the worth of a life: The most worthwhile lives are those high in various objective goods. These principally include welfare and meaning. By distinguishing between worth and welfare, we (...) can capture the intuitive pull of broad theories of welfare without their liabilities. (shrink)

According to a diverse and widely popular family of moral theories, there is a class of individuals – typically humans or persons – who have the very same, full moral status. Individuals not falling into that class count for less, or not at all, morally speaking. In this article, I identify two problems for such theories, the mapping problem and the problem of misgrounded value, and argue that they are serious enough to be decisive. I will then propose an alternative (...) account of full and equal moral status that avoids those problems. In grounding full moral status in phenomenal consciousness, it preserves the idea that you and I are equal, but at the same time radically expands the community of moral equals. I conclude by discussing some practical implications of my proposal. (shrink)

Animalists accuse the advocates of psychological approaches of identity of having to suffer a Problem of Too Many Thinkers. Eric Olson, for instance, is an animalist who maintains that if the person is spatially coincident but numerically distinct from the animal, then provided that the person can use its brain to think, so too can the physically indistinguishable animal. However, not all defenders of psychological views of identity assume the spatial coincidence of the person and the animal. Jeff McMahan and (...) lately Derek Parfit claim we are roughly brain-size, composed of just those parts of the human animal that directly produce thought. They claim to avoid the Problem of Too Many Thinkers because it is the brain-sized person who truly thinks, while the animal thinks only in a derivative sense in virtue of having a thinking proper part. Waiting in the wings are some dualists who claim that all materialist accounts fail to avoid the Problem of Too Many Thinkers. One such dualist, Dean Zimmerman, insists that wherever there is an ordinary material thing like a brain, there is also a mass with distinct persistence conditions and thus the threat of two material thinkers. Zimmerman contends that only positing an immaterial thinker can avoid the problem. (shrink)

Suppose you want to do as much good as possible. What should you do? According to members of the effective altruism movement—which has produced much of the thinking on this issue and counts several moral philosophers as its key protagonists—we should prioritise among the world’s problems by assessing their scale, solvability, and neglectedness. Once we’ve done this, the three top priorities, not necessarily in this order, are (1) aiding the world’s poorest people by providing life-saving medical treatments or alleviating poverty (...) itself, (2) preventing global catastrophic risks, such as those posed by nuclear war or rogue artificial intelligence, and (3) ending factory farming. These claims are both plausible and striking. If correct, they should prompt a stark revision of how we approach our altruistic activities. However, the project of determining how to do the most good—as opposed to say, whether we should do the most good—has only recently, within the last ten years, become the subject of serious academic attention. Many key claims have not yet been carefully scrutinised. This is a cause for concern: are effective altruists doing good badly? In this thesis, I critique and develop some of the latest claims about how individuals can do the most good. I do this in three areas: the value of saving lives (preventing premature deaths), how best to improve lives (making people happier during their lives), and cause prioritisation methodology (frameworks for determining which problems are the highest priorities). In each case, I raise novel theoretical considerations that, when incorporated, change the analysis. Roughly speaking, my main conclusions are (1) saving lives is not as straightforwardly good we tend to suppose, may not be good at all, and is not clearly a priority; (2) happiness can be measured through self-reports and, based on the self-reported evidence, treating mental health stands out as an overlooked problem that may be an even more cost-effective way to improve lives than alleviating poverty; (3) the cause prioritisation methodology proposed by effective altruists needs to be moderately reconceptualised and, when it is, it turns out it is not as illuminating a tool as we might have thought and hoped.

In this dissertation, I investigate the implications of libertarian morality in relation to the problem of climate change. This problem is explicated in the first chapter, where preliminary clarifications are also made. In the second chapter, I briefly explain the characteristics of libertarianism relevant to the subsequent study, including the central non-aggression principle. In chapter three, I examine whether our individual emissions of greenhouse gases, which together give rise to climate change, meet this principle. I do this based on the (...) assumption that we are the legitimate owners of the resources we use in those activities. In the fourth chapter, I question this assumption and scrutinize libertarianism’s restrictions on appropriations of climate-relevant resources, which leads me to distinguish between some different versions of the libertarian view. Toward the end of the chapter, I also examine libertarianism’s answer to the political question regarding how emission rights should be distributed. The fifth chapter investigates libertarianism’s verdicts for mere risks of infringement, as stemming from people’s emissions and acts of appropriations. In chapter six, I investigate the libertarian right to self-defense against both the effects of climate change and other people’s climate-relevant activities. In chapter seven, I discuss two intergenerational issues related to climate change: what libertarianism says concerning future generations and how libertarianism might deal with the problem of historical emissions. The eighth chapter explores the implications of libertarianism regarding collective moral wrongdoing in connection to climate change. In chapter nine, I take a look at the libertarian room for governmental responses for tackling climate change. The tenth and final chapter is a summary. The overall conclusion of the dissertation is that libertarianism recommends that we reduce our emissions and decrease our extraction of natural resources such as forests and fossil fuels. Furthermore, governments are permitted to undertake some quite substantial actions in order to fight the causes of climate change. I end with some bottom-up reflections on what these conclusions might say about the plausibility of libertarianism. I claim that although libertarianism after all manages to explain some of our moral intuitions regarding climate change, it is questionable whether libertarianism’s explanation is better than those offered by alternative moral theories.

What are we? Despite much discussion in historical and contemporary philosophy, we have not yet settled on an answer. A satisfactory personal ontology, an account of our metaphysical nature, will be informed by issues in the metaphysics of material objects. In the dissertation, I target two prominent materialist ontologies: animalism, the view that we are numerically identical to human organisms, and constitutionalism, the view that we are constituted by, but not identical to, human organisms. Because of the problems that arise (...) from endorsing these ontologies, I instead advance immaterialism, the view that we are essentially immaterial. In Chapter 2, I discuss how animalists must respond to a widely-discussed metaphysical puzzle, the problem of the many. This puzzle prompts some to endorse revisionary ontologies of material objects, and I argue that the animalist cannot appeal to these revisionary ontologies to solve the puzzle as it arises for personal ontology. In addition, solutions that don’t involve a commitment to revisionary ontology will be unavailable to the animalist: I argue that if animalists make use of non-revisionary solutions to the problem, they must abandon the most successful argument for their view. Absent their most successful argument, animalists will need to motivate the view in some other way. Some new arguments for animalism have been proposed, and I argue that they fail to give us reason to endorse animalism over competing ontologies. Without a strong argument, we should not prefer animalism over the other, more attractive, views. In Chapter 3, I show how constitutionalists face a different problem: explaining how the person is not the very same thing as the human organism, despite sharing the very same parts and occupying the very same physical space. We think that the person and the organism are different things because they have different modal profiles – the human organism can survive permanent loss of psychological life, but the person, presumably, cannot. Constitutionalists must then explain what grounds the difference in modal profiles, but such an explanation is hard to come by. This is an instance of the grounding problem, which is notoriously intractable. While the grounding problem is a well-known challenge to constitutional accounts of objects, I demonstrate that this puzzle is even more threatening when applied to persons. Some “solutions” to the problem fail to solve it at all, and solutions that might get the right result for ordinary objects require accepting that there are a multitude of persons where we ordinarily take there to be only one. We should not accept a personal ontology that requires a commitment to that multitude. I argue that the threat of the grounding problem is so great that we must reject the constitutionalist personal ontology. We will see from these puzzles in personal ontology that materialist solutions are either unsuccessful or yield unacceptable consequences. This should prompt us toward considering, instead, immaterialism. According to immaterialism, persons are not material objects, and the immaterialist can then provide solutions to the puzzles that threatened materialist ontologies. In Chapter 4, I outline these immaterialist solutions and show that the puzzles cannot be reinstantiated successfully against the immaterialist. I then discuss different available varieties of immaterialism and argue in defense of my preferred version. Ultimately, I argue that we are simple, immaterial entities that come into existence at the proper functioning of the brain. Endorsing this view of personal ontology permits us to adequately respond to metaphysical puzzles and retain judgments about persons that should be most important to us. In particular, the immaterialist has the resources to avoid the problem of too many thinkers and retain the judgment that there is exactly one person in circumstances where we take there to be just one. The immaterialist also has the resources to plausibly analyze thought experiments, such as cerebrum-swap cases, that threaten materialist ontologies. All things considered, it remains to be seen which personal ontology has the most evidence in its favor. In the context of debates that arise from material object metaphysics, however, evidence weighs in favor of immaterialism. Materialist personal ontologies are saddled with unacceptable responses to metaphysical puzzles, and endorsing materialism about persons requires taking on a very high cost: Either there are far more of us than we ordinarily take there to be, or there are no persons – far fewer of us than we ordinarily take there to be. Some might argue that these are the only acceptable options, so cost be damned. But we cannot afford to be so cavalier about our personal ontology. Instead, I advance immaterialist solutions to puzzles in personal ontology and propose that, in the interest of saving ourselves and everyone we love, we should seriously consider accounts according to which we are immaterial entities.

The Covid-19 pandemic has brought to surface new and puzzling manifestations of the culture wars between liberals and conservatives, especially in the US. One such manifestation is the one centered around mask-wearing as a way to protect others from viral infection. In public spaces, mask-wearing has become a signal as to whether one is a liberal or a conservative. Liberals tend to wear the mask and condemn as immoral conservatives, who tend not to wear it. I argue that the liberal (...) attitude does not cohere with liberal theory. I use the issue of the permissibility of abortion and the liberal consensus about it as the benchmark for what a genuine liberal attitude toward mask-wearing should be. (shrink)

While respect for persons is fundamental to many moral and political theories, its nature and ground remain controversial. According to the standard model of respect, respect is primarily a response to certain inherent features of a person or an object. Importantly, it is in virtue of the value, status or authority of those features that respect is justified or owed. This model, however, faces many serious challenges. Drawing on the classical Confucian notion of jing, I develop an alternative model of (...) respect, which construes respect as an expression of agent’s sense of the self and its place in the world. The emphasis is thus on the agent’s own self-conception and the corresponding attitudes and dispositions, as opposed to on inherent features of the objects of respect. To further illustrate this distinction, I contrast the traditional Kantian conception of respect for persons with the Confucian, jing-based, conception along three dimensions: the normative ground, the content, and the distribution of respect. The Kantian respect certainly has its merits, and perhaps is indispensable in some contexts, but there is much more to respect than what Kantians can offer. The Confucian conception of respect, on the other hand, has important theoretical and practical values such that it is essential to an adequate understanding of the role of respect in our moral and political life.

In ‘What Makes Killing Wrong?’ Sinnott-Armstrong and Miller make the bold claim that killing in itself is not wrong, what is wrong is totally-disabling. In ‘After-Birth Abortion: Why Should the Baby Live?’ Giubilini and Minerva argue for allowing infanticide. Both papers challenge the stigma commonly associated with killing, and emphasize that killing is not wrong at some margins of life. In this paper, we first generalize the above claims to the thesis that there is nothing morally wrong with killing per (...) se, so long as it is instant and unannounced. Then, from the perspective of social evolution, we explain why people refrain from killing others, the general guideline being that it is unadvisable to kill someone with whom you associate a Second Person Perspective (SPP). Finally, drawing from a seminal paper of Press and Dyson on the Iterated Prisoner’s Dilemma, we stress that an SPP without an SP (Second Person), or the other way around, can both lead to unwelcome results.
