The nonidentity problem and the two envelope problem have in common an ongoing resistance to intuitive analysis.  They also share certain structural features.  I argue that the two problems proceed under the same error, imagining subjects to draw haphazardly from a potpourri of actual and expected values to generate results about betterness and harm rather than, as we naturally do and always should, draw in a more discriminating way from a more orderly array.  When we play by the same set of rules in calculating the values that we then compare, we, in particular, become able to discern (1) harm in just the cases in respect of which one important variation on the nonidentity problem has long been thought to show “no harm done” and (2) no harm done in the two envelope problem, which purports to show “harm done” when the subject refuses endlessly to switch from one envelope to another and back again.

The issue of wrongful disability arises when parents face the choice whether to produce a child whose life will be unavoidably flawed by a serious disease or disorder (Down syndrome, for example, or Huntington’s disease) yet clearly worth living.  The authors of From Chance to Choice claim, with certain restrictions, that the choice to produce such a child is morally wrong.  They then argue that an intuitive moral approach—a “person-affecting” approach that pins wrongdoing to the harming of some existing or future person—cannot account for that wrong since the choice to produce such a child cannot, under the logic of the nonidentity problem, harm that child.  The authors propose that we supplement the person-affecting approach with an “impersonal” principle that takes the form of their well-known principle N.  In this paper, I argue that the authors are mistaken to suppose that a plausibly articulated person-affecting approach cannot account for the wrong of wrongful disability.  We can retain an intuitive, comparative, “worse for” account of harm and still identify serious harms imposed by the choice of wrongful disability.  In particular, I argue that harm, both to the impaired child and to others, comes not in the form of that procreative choice’s procreative effect but rather in the form of its many distributive effects.  I argue, moreover, that that harm result can support the claim that the parents' choice is morally wrong as well as the impaired child's legal claim (for "wrongful life") against the health care provider whose negligent failure to diagnose or inform parents of an increased risk of a genetic or congenital impairment results in the birth of the impaired child.

Draft of "The Nonidentity Fallacy"

Link to final text at Utilitas

The nonidentity problem is really a collection of problems having distinct logical features. For that reason, they can be typed. This paper focuses on just one type of nonidentity problem, the ‘can’t-expect-better’ problem, which includes Derek Parfit’s depletion example and many others. The can’t-expect-better problem uses an assessment about the low probability of any particular person’s coming into existence to reason that an earlier wrong act does not harm that person. This paper argues that that line of reasoning is unusually treacherous in that it makes not just one hard-to-detect error in what is done with the relevant probability assessments but rather alternates between two. We sort out one mistake only to fall, against all odds (as it were), into a second. By avoiding both errors, we become able to discern harm in cases in which the can’t-expect-better problem argues there is none. We will then be in a position to set aside the can’t-expect-better problem as an objection against the person-based intuition that acts that are ‘bad’ must be ‘bad for’ at least some existing or future person.

          Draft of "Supernumerary Pregnancy"

Link to final text at Jo. Law, Medicine and Ethics

An interesting question, in both the moral and the legal context, is whether the babies born of an infertility treatment-induced supernumerary (or multi-fetal) pregnancy (or “ITISP”) are properly considered to have been harmed.  One might wonder how such a question could even arise in the face of data that clearly demonstrate that ITISP leaves an unduly large number of babies blind, deaf and palsied and facing life-long disabilities.  In fact, however, a number of arguments, based on the problem of collective harm and two forms of the so-called “nonidentity problem,” challenge the claim of harm in the ITISP context.  The purpose of the present paper is to establish, as against these arguments, that harm has been imposed on the ITISP-damaged offspring.

          Link to TOC for the collection and to my paper

This article explores a person-based account of the repugnant conclusion, investigating, along the way, the "extinction problem" as a leading challenge to such an account.  The argument is made that a careful consideration of what we understand our own obligations to be in contemporary life -- including our obligations with respect to already-existing people -- casts doubt on the idea that, in general, agents have an obligation to bring new people into existence just in case doing so will contribute to total, aggregate, utility or wellbeing. 

●  "Supernumerary Pregnancy and the Limits of the Constitutional Privacy Guaranty," Jo. of Philosophical Research 105-117(2005)

The claim of this article is that the privacy guaranty of the Fourteenth Amendment does not protect the choice to commence or continue a supernumerary pregnancy when the consequence of doing so presents risks of harm to prospective offspring in the form of physical, intellectual or emotional deficiencies.  This is so, it is argued, notwithstanding the fact that the reproductive choice (for example, the use of strong fertility drugs in the absence of procedures designed to avoid multiple pregnancy) is part of the causal chain that eventuates in the existence of those offspring, who (probably) would never have otherwise existed at all.

This article critically examines some of the inconsistency objections that have been raised by John Broome and Larry Temkin against the so-called "person-affecting" restriction in normative ethics, including "additional people" problems (especially the mere addition paradox and issues relating to "Pareto-Plus") and a version of the nonidentity problem from Kavka and Parfit.  Paradoxes can be avoided, it is argued, by situating the person-affecting intuition within a certain form of maximizing consequentialism (in competition with "total" and "average" forms of maximizing consequentialism).

          Draft of "Can It Ever Have Been Better"

This article critically considers a handful of arguments to the conclusion that statements purporting to assert that never having existed at all can be better, in the case of some individuals, than existence are always incoherent or at least untrue.  The article concludes that such arguments fail and that it is both coherent and plausibly true that it would have been better, in the case of certain persons, that they never have existed at all.

This paper argues that a person-affecting, or "person-based," form of consequentialism includes the best features of traditional, aggregative forms of maximizing consequentialism yet is not vulnerable to many of the most telling objections such forms of consequentialism.  Among other things, person-based consequentialism leaves a clearly defined role for considerations of equality.  This paper also suggests that the "leximin" principle captures much of what we think is right about equality without taking us too far in the direction of "equalism."

●  "Cloning and Harming:  Children, Future Persons and the 'Best Interest' Test," 13 Notre Dame Jo. of Law, Ethics & Public Policy 37-61 (1999)

We can predict that, should reproductive cloning ever become an option, we adults will insist on the right of consent before we will allow our own genomes to be used for purposes of reproductive cloning.  Whether conceived of in legal or moral terms, what we aim to protect in insisting on a right of consent is an interest in "privacy."  This article argues that the same interest should be respected in the case of children and future persons.  Just as we would not (and in many states legally should not) use a child -- who is in no position to consent -- as a kidney donor unless we are sure that acting as such a donor is in the child's own best interest, I argue that neither children nor future persons should be used as clone sources or intentionally brought into existence as clones -- as one of two or more genetically identical individuals -- unless there is a clear showing that such a violation of their interest in privacy serves their own best interest.

●  "Human Cloning:  A Case of No Harm Done?" 21 Jo. of Med. and Phil. 537-54 (1996)

Link to final text at Jo. of Med. and Phil.

The focus of this article is the nonidentity problem, developed by Parfit, Kavka and others, and its application to reproductive cloning technologies.  John Robertson has put forward a version of the nonidentity problem as an argument that reproductive cloning will not cause harm to the offspring that it will be used to produce.  Richard McCormack has argued that the acceptance of human reproductive cloning would undermine the dignity of the human embryo and would constitute a breach of the respect that he thinks we owe to the embryo as human.  The terms of their debate suggests that one must either support human reproductive cloning or reject abortion as a morally permissible option.  I argue, however, that we can identify respects in which reproductive cloning causes specific sorts of harm to offspring and hence that we have grounds to reject human reproductive cloning that have no adverse implication for our full and robust support for the right of abortion.

●  "Parent and Child in Conflict: Between Liberty and Responsibility," 10 Notre Dame Jo. of Law, Ethics and Public Policy 485-542 (1996)

The focus of this article is the case of "Baby Richard," who, after a failed adoption, was returned at the age of four to a biological father whom the child had never seen before.  The main argument of the article is that, just as adults have parental rights that we think warrant protection under the Fourteenth Amendment's due process guaranty, so should children be understood to have "affiliational" rights that likewise merit constitutional protection.  Such rights would counterbalance in extreme circumstances the parent's right of custody and control with respect to his or her own biological offspring.

●  "Present Duties and Future Persons: When Are Existence-Inducing Acts Wrong?" 14 Law and Philosophy 297-327 (1995)

This article takes a close look at the nonidentity problem in its many forms.  Thus, counterfactual, probabilistic and more broadly modal forms of the argument are considered and, in some cases, rejected as flawed.  The analysis has been revised and clarified in Chapter 3 of Child Versus Childmaker ("The Nonidentity Problem").

●  “Sexual Harassment, the Acquiescent Plaintiff and the ‘Unwelcomeness’ Requirement,” in D. Bushnell, ed., Nagging Questions (Rowman & Littlefield, 1995) 105-121

This article considers a certain requirement that the Supreme Court has imposed in connection with claims brought for sexual harassment under Title VII of the Civil Rights Act, as amended.  According to the Supreme Court, the plaintiff must establish that the defendant’s conduct, in addition to creating unreasonable burdens on the plaintiff that discriminate against the plaintiff on the basis of her sex, is “unwelcome” to her.  Meritor Savings.   This article argues that the unwelcomeness requirement is unjustified.  It is very difficult for the plaintiff to establish her subjective “state of mind” months or years after the questionable conduct occurred.  Moreover, it is a requirement that serves no clear policy or legislative purpose, in view of the other showings of fact that the plaintiff is independently required to make under Title VII. 

●  "A Way of Looking at the Dalla Corte Case," 22 Jo. of Law, Medicine and Ethics 339-42 (1994)

I argue that, when the postmenopausal woman's own ongoing partner is the sperm source, it is difficult to conclude that postmenopausal pregnancy is somehow immoral or should be made illegal.  This argument leaves the question of moral status open in the case were both egg and sperm are donated.  In both cases, the main concern would be the consequences of the technology for the child.  In the former case, it is difficult to see any other reasonable alternative by which the particular child could both exist and not suffer the risk of having a beloved parent die when the child is still young.  In the latter case, it is easy to pinpoint an alternative course of action that would allow the particular child both to exist and avoid the risk.  The moral analysis thus seems to be different in the one case as compared to the other.

●  "Good Intentions and a Great Divide: Having Babies by Intending Them," 12 Law and  Philosophy 287-317 (1993)

The focus of this article is commercial surrogacy and Richard Posner's argument that, from the child's point of view, no objection to commercial surrogacy can be sensibly made in view of the fact that the child owes his or her very existence to the practice of surrogacy.  I argue that this defense of surrogacy is flawed in view of the fact that by the time the question of the contract's enforceability is properly raised the child exists; declaring the contract unenforceable will not in any way change that fact.  At the same time, declaring the contract unenforceable represents a step forward from the child's point of view since it means that the child's placement will be determined, not by the terms of the commercial contract, but rather in accordance with the child's own "best interest."

●  "Distinguishing Wrongful From ‘Rightful' Life," 6 Jo. of Contemporary Health Law and Policy 59-80 (1990)

This paper argues that the tort of "wrongful life" should be recognized.  The particular focus is on arguments that conclude that claims of wrongful life are somehow self-contradictory or incoherent.  I argue that they are neither.
