The asymmetry is the view in population ethics that, while we ought to avoid creating additional bad lives, there is no requirement to create additional good ones. The question is how to embed this intuitively compelling view in a more complete normative theory, and in particular one that treats uncertainty in a plausible way. While arguing against existing approaches, I present new and general principles for thinking about welfarist choice under uncertainty. Together, these reduce arbitrary choices to uncertainty-free ones, (...) regardless of how the latter should be made. I illustrate these principles by developing two theories of the asymmetry, reflecting different views about the non-identity problem. In doing so, I clarify some other major choice-points, presenting new arguments that creating additional good lives can justify (but not require) doing harm. Finally, I consider what the developed theories have to say about the importance of extinction risk and the long-run future. (shrink)

If earlier-than-necessary death is bad because it deprives individuals of additional good life, then why isn't later-than-necessary conception bad for the same reason? Deprivationists have argued that prenatal non-existence is not bad because it is impossible to be conceived earlier, but postmortem non-existence is bad because it is possible to live longer. Call this the Impossibility Solution. In this paper, I demonstrate that the Impossibility Solution does not work by showing how it is possible to be conceived earlier in the (...) same senses it is possible to live longer. I then offer a solution to the Asymmetry Problem by suggesting a novel way to separate the badness of each type of non-existence from the type, and frequency, of attitudes we should have towards each type of non-existence. Even if both types of non-existence are equally bad, certain contingent facts about our postmortem non-existence provide reason for the badness of early deaths to be more frequently salient than the badness of late conceptions.

The Asymmetry consists of two claims. (A) That a possible person's life would be abjectly miserable –less than worth living – counts against bringing that person into existence. But (B) that a distinct possible person's life would be worth living or even well worth living does not count in favour of bringing that person into existence. In recent years, the view that the two halves of the Asymmetry are jointly untenable has become increasingly entrenched. If we say all (...) persons matter morally whether they exist or not and on that basis try to explain the first half of the Asymmetry, we lose the second half of the Asymmetry. If we say that some persons do not matter morally and some do and on that basis try to explain the second half of the Asymmetry, we lose the first half of the Asymmetry – or else find ourselves with a principle that is either inconsistent or otherwise deeply troubled in some way that has nothing to do with the content of the Asymmetry itself. In this article, I propose an alternative approach to the Asymmetry which I will call Variabilism. By understanding each and every person, whether existing or not, to matter morally but variably– such that the moral significance of any loss incurred by any person is considered to depend, not on who incurs that loss and whether that person matters morally, but rather on where that loss is incurred in relation to the person who incurs it – we can both nicely ground the two halves of the Asymmetry and avoid the conceptual difficulties that have plagued competing approaches.

Sam signaled a turn by extending his arm out the window. Difficulties in explaining the asymmetry of the by-relation in such examples by reference to acceptable and unacceptable counterfactual conditionals are explored by Hugh McCann in "The Trouble with Level-Generation" ("Mind", October 1982). I refine and defend the following alternative account of one-way dependence of y on x: not only is x necessary for y, but something else, independent from x, is also necessary for y; but there is nothing (...) independent from y such that it and y are each necessary for x.

This dissertation intends to contribute to the discussion about the asymmetry W. V. Quine sees between indeterminacy of translation and underdetermination of theory. Quine often formulates the asymmetry by saying that there is a fact of the matter to physics but none to translation. The first chapters of the dissertation constitute an attempt of clarification of that notion of fact of the matter. They contain an analysis of the relations between Quine's notion of fact of the matter, his (...) physicalism, and his conception of truth. The main conclusion of those chapters is that the notion of fact of the matter is physicalistic, which means that it is what, according to Quine, embodied the nature of extralinguistic reality that determines truth. The next chapters contain an analysis of Quine's indeterminacy of translation thesis and underdetermination of theory. The main conclusions of those chapters are the following: indeterminacy of translation is an ontological thesis, and its content has not changed through Quine's writings, although the formulations of the thesis have varied; Quine's definitive arguments for indeterminacy of translation are not to be found in his physicalism, but in his behaviorism; underdetermination of theory is a methodological doctrine, for it concerns the evidential link between observation and theory; there is an asymmetry between indeterminacy of translation and underdetermination of theory. The remaining chapters of the dissertation constitute a review of the main texts by other authors addressing Quine's claim that there is an asymmetry between indeterminacy of translation and underdetermination of theory. The positions of Noam Chomsky, Richard Rorty, and Micheal Friedman are analyzed and criticized. The positions of Dagfinn Follesdal and Roger Gibson have appeared to our lights as the ones that should be taken most seriously. Follesdal is the one who seems to have accomplished the last progresses in the discussion over the asymmetry between underdetermination of theory and indeterminacy of translation by distinguishing clearly Quine's epistemological arguments for indeterminacy of translation thesis from the ontological content of that thesis.

Population ethics is widely considered to be exceptionally important and exceptionally difficult. One key source of difficulty is the conflict between certain moral intuitions and analytical results identifying requirements for rational (in the sense of complete and transitive) social choice over possible populations. One prominent such intuition is the Asymmetry, which jointly proposes that the fact that a possible child’s quality of life would be bad is a normative reason not to create the child, but the fact that a (...) child’s quality of life would be good is not a reason to create the child. This paper reports a set of questionnaire experiments about the Asymmetry in the spirit of economists’ empirical social choice. Few survey respondents show support for the Asymmetry; instead respondents report that expectations of a good quality of life are relevant. Each experiment shows evidence (among at least some participants) of dual-process moral reasoning, in which cognitive reflection is statistically associated with reporting expected good quality of life to be normatively relevant. The paper discusses possible implications of these results for the economics of population-sensitive social welfare and for the conflict between moral mathematics and population intuition. (shrink)

The Asymmetry in procreative ethics consists of two claims. The first is that it is morally wrong to bring into existence a child who will have an abjectly miserable life; the second is that it is permissible not to bring into existence a child who will enjoy a very happy life. In this paper, I distinguish between two variations of the Asymmetry. The first is the Abstract Asymmetry, the idealized variation of the Asymmetry that many philosophers (...) have been trying to solve. The second is the Real-World Asymmetry, a non-idealized variation that applies explicitly to cases of ordinary human reproduction. I argue that the Real-World Asymmetry can be defended by properly acknowledging the general wrongness of causing someone else to suffer, the limits of what morality can reasonably demand of us, and the significance of respecting women’s autonomy. I then argue that the Abstract Asymmetry is indefensible. (shrink)

According to the Asymmetry, we’ve strong moral reason to prevent miserable lives from coming into existence, but no moral reason to bring happy lives into existence. This procreative asymmetry is often thought to be part of commonsense morality, however theoretically puzzling it might prove to be. I argue that this is a mistake. The Asymmetry is merely prima facie intuitive, and loses its appeal on further reflection. Mature commonsense morality recognizes no fundamental procreative asymmetry. It may (...) recognize some superficially similar theses, but we will see that they derive from more familiar principles, and are compatible with there being moral reason to bring happy lives into existence.

Desert plays a central role in most contemporary theories of retributive justice, but little or no role in most contemporary theories of distributive justice. This asymmetric treatment of desert is prima facie strange. I consider several popular arguments against the use of desert in distributive justice, and argue that none of them can be used to justify the asymmetry.

State legitimacy is often said to have two aspects: an internal and an external one. Internally, a legitimate state has the right to rule over its subjects. Externally, it has a right that outsiders not interfere with its domestic governance. But what is the relation between these two aspects? In this paper, I defend a conception of legitimacy according to which these two aspects are related in an importantly asymmetrical manner. In particular, a legitimate state’s external right to rule affords (...) it protections that include and go beyond what its internal right to rule enables it to do. This asymmetrical view, I argue, is preferable to its two main rivals: the view that a state’s internal and external legitimacy are separate issues, and the view that internal and external legitimacy are mirroring.

A crucial disanalogy between Twin Earth and Inverted Earth undermines qualia‐internalism. A recent transplant to Inverted Earth has been equipped with color‐inverting contact lenses, so that she is unable to see the colors of objects whereas a recent transplant to Twin Earth can see twater. It is implausible to think that time alone could rectify this perceptual shortcoming – that the passage of time could alter the contents of her visual perceptions or the meaning of her color terms. Thus, the (...) thought experiment does not refute the close tie between phenomenology and representation in the case of color. (shrink)

An important aspect of the debate between the A-theory and the B-theory of time relates to the supposed implications of each for some of the most basic human attitudes and stances. The asymmetry in our attitudes towards past and future events in our life (pleasant and unpleasant), and towards the temporal limits of our existence, that is, toward birth and death, is supposedly considered differently by the two theories. I argue that our attitudes are neither justified nor discredited by (...) anything which is in debate between the A-Theory and the B-theory, and therefore that neither theory of time is supported by the asymmetry in our attitudes.

Is there a prima facie obligation to produce additional individuals whose lives would be worth living? In his paper ‘Is it Good to Make Happy People?’, Stuart Rachels argues not only that there is, but, also, that precisely as much weight should be assigned to the quality of life that would be enjoyed by such potential persons, if they were to be actualized, as to the quality of life enjoyed by actually existing persons. In response, I shall argue, first, that (...) Rachels’ view is exposed to very serious objections, and secondly, that his arguments in support of his position involve a crucial assumption, which cannot be sustained, concerning the relation between, on the one hand, propositions about good‐making and bad‐making properties, and, on the other, propositions about right‐making and wrong‐making ones. I shall then argue that there is a very plausible position concerning the conditions under which an action can be morally wrong which entails the following asymmetry: there is a prima facie obligation not to bring into existence individuals whose lives are not worth living, but there is no corresponding obligation to create additional individuals whose lives would be worth living.

According to the Asymmetry Thesis, whereas there are many kinds of argument-forms that make at least some of their instances valid, there is none that makes any of its instances invalid. To refute this thesis, a counterexample has been produced in the form of an argument-form whose premise-form's instances are all logically true and whose conclusion form's instances are all logically false. The purpose of this paper is to show that there are many more kinds of argument-forms that make (...) some of their instances invalid and that, hence, are counterexamples refuting the Asymmetry Thesis.

Why believe Hume's Dictum, according to which there are, roughly speaking, no necessary connections between wholly distinct entities? Schaffer suggests that HD, at least as applied to causal or nomological connections, is motivated as required by the best account of of counterfactuals---namely, a similarity-based possible worlds account, where the operative notion of similarity requires 'miracles'---more specifically, worlds where entities of the same type that actually exist enter into different laws. The main cited motivations for such an account of similarity are (...) first, that some salient contexts presuppose CF asymmetry, and second, that accounts of CFs failing to presuppose CF asymmetry are epistemologically problematic, such that under conditions of determinism, the variations in initial micro-conditions needed to implement a given counterfactual antecedent would result in so many changes to macro-states that evaluation of CFs would be rendered practically impossible. Against the first reason, I argue that no non-artificial contexts presuppose CF asymmetry; against the second, I observe that such micro-variation is compatible, in principle, with significant similarity as regards macroscopic states of affairs---enough, in particular, to allow CFs to be appropriately evaluated.

This paper suggests a novel reinterpretation of the mathematical core of Wheeler-Feynman absorber theory, and hence a new route to the conclusion that the temporal asymmetry of classical electromagnetic radiation has the same origin as that of thermodynamics. The argument begins (Sec. 2) with a careful analysis of what the apparent asymmetry of radiation actually involves. Two major flaws in the standard version of the Wheeler-Feynman treatment of radiative asymmetry are then identified (Secs. 4–5), and the proposed (...) reinterpretation is described (Sec. 6). This avoids the two flaws previously mentioned, and also the problematic dependence of radiation on cosmological structure. (shrink)

As the Roman philosopher Lucretius asked, why do we fear and regret death, but do not regret not having been born earlier, when death and prenatal nonexistence are mirror images? Both deprive us of goods we might have had, and this deprivation most plausibly explains the badness of death. This paper first considers and rejects explanations other than the deprivation of goods. It then suggests an explanation in terms of a state of which death deprives us, and which is itself (...) asymmetrical in regard to the future and the past. This sharp asymmetry in this one very important good helps to justify the difference in our attitudes, especially among those for whom death approaches. The paper departs from the usual rigid format in which a philosopher says what she is going to say, then says it, and then repeats it. In matching form to mystery content, the missing clue to the solution will not be revealed until later in the paper. (shrink)

Political liberalism offers perhaps the most developed and dominant account of justice and legitimacy in the face of disagreement among citizens. A prominent objection states that the view arbitrarily treats differently disagreement about the good, such as on what makes for a good life, and disagreement about justice. In the presence of reasonable disagreement about the good, political liberals argue that the state must be neutral, but they do not suggest a similar response given reasonable disagreement about what justice requires. (...) A leading political liberal, Jonathan Quong, has recently offered a rebuttal to this asymmetry objection. His reply rests on an innovative distinction between justificatory and foundational disagreement. Quong claims that disagreements about justice in a well ordered society are justificatory while disagreements about the good are foundational, and suggests that this fact blocks the asymmetry objection. We assess Quong's solution and argue that it fails to justify legitimate state action on matters of justice but not the good. We conclude that the asymmetry objection continues to undermine political liberalism. (shrink)

This paper evaluates Jonathan Quong’s attempt to defend a version of political liberalism from the asymmetry objection. I object that Quong’s defence relies on a premise that has not been adequately supported and does not look as if it can be given adequate support.

There are two bodies of literature, one offering theories of the legitimacy of domestic institutions like states, another offering theories of the legitimacy of international institutions like the IMF. Accounts of domestic legitimacy stress the importance of democratic procedure, while few to no theorists make democracy a necessary condition for the legitimacy of international institutions. In this paper, I ask whether this asymmetry can be defended. Is there a unified higher-order theory which can explain why legitimacy requires democracy in (...) the domestic context, but not in the international context? I argue that no proceduralist higher-order theory succeeds, and that we need to look for other solutions. (shrink)

MacFarlane (2014) advocates a radical form of semantic relativism. He argues that his proposal complies with the norms governing our assertion practices in various areas of discourse. These practices also include norms regarding the conditions in which it is inappropriate not to retract an assertion. Ferrari & Zeman (2014) identify an asymmetry concerning retractions in two relevant areas of discourse and argue that assessment-sensitivity needs to be supplemented with further theoretical tools to explain it. I dispel the asymmetry (...) and conclude that assessment-sensitivity needs no supplementation to account for it. (shrink)

It is widely considered a truism that the only evidence that can provide justification for one's belief that p is evidence in one's possession. At the same time, a good many epistemologists accept another claim seemingly in tension with this "truism," to the effect that evidence not in one's possession can defeat or undermine the justification for one's belief that p. Anyone who accepts both of these claims accepts what I will call the asymmetry thesis: while evidence in one's (...) possession can either enhance or detract from justification, evidence not in one's possession can only detract from it. The asymmetry thesis is not uncontroversial; but any epistemologist who endorses the doctrine of normative defeat will be under tremendous pressure to accept it. In this paper I try to motivate the asymmetry thesis in two steps: first, by appeal to a feature that assessments of justification share with evaluative assessments generally, according to which we can distinguish generic expectations in play from the explicit criteria for satisfying the relevant evaluative standard; and second, by arguing that when it comes to epistemic assessments, the generic expectations themselves derive from our roles as epistemic agents in communities in which we depend on one another for knowledge.

For many laws causal asymmetries in dependencies among the variables are not reflected in functional relations of the law equation. In the case of the simple pendulum law, why can we cite the length to explain the period but not the period to explain the length? After surveying attempts to explain the asymmetries, I propose a new account based on an analysis of the relation of causes and laws. This analysis is used to criticize the very notion of causal laws (...) and to clarify the role of ceteris paribus clauses in interpreting scientific laws. (shrink)

In "Counterfactual Dependence and Time's Arrow", David Lewis defends an analysis of counterfactuals intended to yield the asymmetry of counterfactual dependence: that later affairs depend counterfactually on earlier ones, and not the other way around. I argue that careful attention to the dynamical properties of thermodynamically irreversible processes shows that in many ordinary cases, Lewis's analysis fails to yield this asymmetry. Furthermore, the analysis fails in an instructive way: it teaches us something about the connection between the (...) class='Hi'>asymmetry of overdetermination and the asymmetry of entropy. (shrink)

It is widely believed by philosophers that we human beings are capable of stepping back from inclinations to act in a certain way and consider whether we should do so. If we judge that there are enough reasons in favour of following our initial inclination, we are definitely motivated, and, if all goes well, we act. This view of human agency naturally leads to the idea that our actions are self-determined, or controlled by ourselves. Some go one step further to (...) the point of saying that we should extend the fundamental aspects of this view of human agency to the epistemic realm. This we call ‘the control-view”. Here we will make a strong case against the control-view. While we have a substantial control over our practical lives, it is very unlikely that this extends to our epistemic lives. Our discussion will proceed in three stages. We will present two asymmetries between our practical and epistemic lives which are followed by a general argument against the control-view. (shrink)

How do we distinguish between cause and effect? The main argument of this paper is that if a realist account of the meaning of causal statements is adopted, then two clear distinctions between cause and effect emerge. By realist account is meant conceiving a cause as something with a power to act. Since a realist approach to causality is not widely accepted among philosophers, two arguments against a realist approach to causality are countered. The asymmetry of causality is defended (...) against the claim that physics, in the main, describes a symmetrical universe. (shrink)

The paper reviews Balashov’s Asymmetry Thesis concerning co-existing (point-sized) enduring objects, on the one hand, and perduring ones, on the other. In this regard, it becomes crucial to investigate whether, at a given spacetime point p, it is located only the respective temporal part of a perdur- ing whole, or that whole as well. Two alternatives ought to be distinguished and, then, I will argue as follows: If the perduring whole is located where its parts are, the original (...) class='Hi'>asymmetry- thesis has to be rejected. If, however, the perduring whole is not located where its parts are, the spatiotemporal locations of the parts can no longer be used to ground the co-existence relation. But, with the modified co-existence relation the asymmetry between perdurantism and endurantism turns out to be even much stronger than it has been assumed. (shrink)

The emphasis on discoveries moves the Nobel Prize further away from its original intention to reward the greatest contribution to society in the preceding year. We propose (...) to strengthen the role of inventions for the Nobel Prize, which would encourage inventors to tackle important problems, such as global warming or the gap between the first and the third worlds.

We seem less likely to endorse moral expertise than reasoning expertise or aesthetic expertise. This seems puzzling given that moral norms are intuitively taken to be at least more objective than aesthetic norms. One possible diagnosis of the asymmetry is that moral judgments require autonomy of judgement in away that other judgments do not. However, the author points out that aesthetic judgments that have been ‘borrowed’ by aesthetic experts generate the same autonomy worry as moral judgments which are borrowed (...) by moral experts. The author then explores various approaches to accepting the testimony of moral experts and concludes that the asymmetry may best be explained by (1) the conditions for moral expertise being more difficult to satisfy than those of aesthetic expertise and (2) the intuitive greater seriousness of accepting the moral judgments of others, since moral norms are generally viewed as more binding than aesthetic norms.

Is the procreation asymmetry intuitively supported? According to a recent article in this journal, an experimental study suggests the opposite. Dean Spears (2020) claims that nearly three-quarters of participants report that there is a reason to create a person just because that person’s life would be happy. In reply, I argue that various confounding factors render the study internally invalid. More generally, I show how one might come to adopt the procreation asymmetry for the wrong reasons by misinterpreting (...) one’s intuitions. (shrink)

The standard versions of predicativism are committed to the following two theses: proper names are count nouns in all their occurrences, and names do not refer to objects but express name-bearing properties. The main motivation for predicativism is to provide a uniform explanation of referential names and predicative names. According to predicativism, predicative names are fundamental and referential names are explained by appealing to a null determiner functioning like “the” or “that.” This paper has two goals. The first is to (...) reject the predicativists’ explanation of the two types of names. I present three syntactic counterexamples to the predicativists’ account of referential names: incorporation, modification, and measure phrase uses. The second goal is to present a novel strategy to explain the two types of names. I propose that referential names are fundamental but that there are null morphemes available for transforming a name into a count noun (and possibly into other syntactic categories). (shrink)

Government refusals to apologise for past wrongful practices such as slavery or the removal of indigenous children from their parents seem evidently unjust. It is surprising, then, that some ethical considerations appear to support such stances. Jacques Derrida's account of forgiveness as entirely independent of apology appears to preclude the need for official apologies. I contend that governments are obligated to apologize for past injustices because they are responsible for them and that official apologies should not involve a corresponding expectation (...) for forgiveness. My argument is that an apology and forgiveness are asymmetrical because an apology is based on respect, a perfect duty, and can be a public act, whereas forgiveness is based on love, is an imperfect duty, and is a personal undertaking. It follows from this asymmetry that an apology is a prerequisite for reconciliation, but forgiveness is discretionary. Refusals to apologize tend to impede the reconciliation process and make the possibility of forgiveness remote. The concept of reconciliation has also been criticized on the grounds that reconciliation implies a former harmony that should be restored and fault on both sides. However, I argue it should be understood as a willingness to work together without a presumption of having overcome the past. (shrink)

In a series of articles Gerald Massey has defended “the asymmetry thesis,” the thesis that “at the present stage of logical theory our ability to prove validity totally eclipses our ability to show invalidity.” My initial strategy in discussing this thesis will be to close in on it gradually by considering, sometimes summarily but sometimes in greater detail, various distinguishable theses in the neighborhood, gradually approximating the thesis which Massey wishes to defend.

A basic intuition we have regarding the nature of time is that the future is open whereas the past is fixed. For example, whereas we think that there are things we can do to affect how the future will unfold, we think that there are not things we can do to affect how the past unfolded. However, although this intuition is largely shared, it is not a straightforward matter to determine the nature of the asymmetry it reflects. So, in (...) this paper, I survey various philosophical ways of characterizing the asymmetry between the ‘open future’ and the ‘fixed past’ in order to account for our intuition. In particular, I wonder whether the asymmetry is to be characterized in semantic, epistemic, metaphysical or ontological terms. I conclude that, although many of these characterizations may contribute to a global understanding of the phenomenon, an ontological characterization of the asymmetry is to be preferred, since it is superior to the alternatives in explanatory power, intelligibility, and in how it coheres with interesting senses of openness.

A common intuition is that there is a moral difference between ‘making people happy’ and ‘making happy people.’ This intuition, often referred to as ‘the Asymmetry,’ has, however, been criticized on the grounds that it is incoherent. Why is there, for instance, not a corresponding difference between ‘making people unhappy’ and ‘making unhappy people’? I argue that the intuition faces several difficulties but that these can be met by introducing a certain kind of reason that is favouring but non-requiring. (...) It is argued that there are structural similarities between the asymmetry and moral options and that the asymmetry can be defended as an instance of a moral option. (shrink)
