A person-affecting or person-based view (also called person-affecting restriction [1] ) in population ethics captures the intuition that an act can only be bad if it is bad for someone. [2] Similarly something can be good only if it is good for someone. Therefore, according to standard person-affecting views, there is no moral obligation to create people nor moral good in creating people because nonexistence means "there is never a person who could have benefited from being created". Whether one accepts person-affecting views greatly influences to what extent shaping the far future is important if there are more potential humans in the future. [3] Person-affecting views are also important in considering human population control.
A weaker form of person-affecting views states that an act can only be bad if it is bad for some existing or future person.
Person-affecting views can be seen as a revision of total utilitarianism in which the "scope of the aggregation" is changed from all individuals who would exist to a subset of those individuals (though the details of this vary, see the section below). [3] [4]
Some philosophers who have discussed person-affecting views include Derek Parfit, Jan Narveson, John Broome, Jeff McMahan, Larry Temkin, Tatjana Višak, Gustaf Arrhenius, Johann Frick, Nick Beckstead, and Hilary Greaves.
There is no single "person-affecting view" but rather a variety of formulations all involving the idea of something being good or bad for someone. [5]
There are also asymmetric views, according to which it is considered bad or wrong to bring into this world lives that are not worth living, even though it is morally neutral to bring into this world lives that are worth living. [3] Hard asymmetric views in particular can lead one to conclude that human extinction (or the extinction of all life) is good, according to Beckstead. [3] However, according to Simon Knutsson, this can be the case for utilitarianism and consequentialism generally, not just asymmetric consequentialist theories, like negative utilitarianism and negative consequentialism. [7]
Soft asymmetric views, like described by Teruji Thomas, hold that additional lives worth living can make up for bad lives, but once the bad lives are made up for, more lives worth living do not improve the outcome. [8] These are less prone to the conclusion that extinction is good than hard asymmetric views.
In moral philosophy, consequentialism is a class of normative, teleological ethical theories that holds that the consequences of one's conduct are the ultimate basis for judgement about the rightness or wrongness of that conduct. Thus, from a consequentialist standpoint, a morally right act is one that will produce a good outcome. Consequentialism, along with eudaimonism, falls under the broader category of teleological ethics, a group of views which claim that the moral value of any act consists in its tendency to produce things of intrinsic value. Consequentialists hold in general that an act is right if and only if the act will produce, will probably produce, or is intended to produce, a greater balance of good over evil than any available alternative. Different consequentialist theories differ in how they define moral goods, with chief candidates including pleasure, the absence of pain, the satisfaction of one's preferences, and broader notions of the "general good".
Hedonism refers to the prioritization of pleasure in one's lifestyle, actions, or thoughts. The term can include a number of theories or practices across philosophy, art, and psychology, encompassing both sensory pleasure and more intellectual or personal pursuits, but can also be used in everyday parlance as a pejorative for the egoistic pursuit of short-term gratification at the expense of others.
Normative ethics is the study of ethical behaviour and is the branch of philosophical ethics that investigates questions regarding how one ought to act, in a moral sense.
In ethical philosophy, utilitarianism is a family of normative ethical theories that prescribe actions that maximize happiness and well-being for the affected individuals. In other words, utilitarian ideas encourage actions that ensure the greatest good for the greatest number. Although different varieties of utilitarianism admit different characterizations, the basic idea behind all of them is, in some sense, to maximize utility, which is often defined in terms of well-being or related concepts. For instance, Jeremy Bentham, the founder of utilitarianism, described utility as the capacity of actions or objects to produce benefits, such as pleasure, happiness, and good, or to prevent harm, such as pain and unhappiness, to those affected.
Derek Antony Parfit was a British philosopher who specialised in personal identity, rationality, and ethics. He is widely considered one of the most important and influential moral philosophers of the late 20th and early 21st centuries.
In ethics, welfarism is a theory that well-being, what is good for someone or what makes a life worth living, is the only thing that has intrinsic value. In its most general sense, it can be defined as descriptive theory about what has value but some philosophers also understand welfarism as a moral theory, that what one should do is ultimately determined by considerations of well-being. The right action, policy or rule is the one leading to the maximal amount of well-being. In this sense, it is often seen as a type of consequentialism, and can take the form of utilitarianism.
The mere addition paradox is a problem in ethics identified by Derek Parfit and discussed in his book Reasons and Persons (1984). The paradox identifies the mutual incompatibility of four intuitively compelling assertions about the relative value of populations. Parfit’s original formulation of the repugnant conclusion is that "For any perfectly equal population with very high positive welfare, there is a population with very low positive welfare which is better, other things being equal."
The utility monster is a thought experiment in the study of ethics created by philosopher Robert Nozick in 1974 as a criticism of utilitarianism.
Average and total utilitarianism are variants of utilitarianism that seek to maximize the average or total amount of utility; following Henry Sidgwick's question, "Is it total or average happiness that we seek to make a maximum?". They are theories of population ethics, a philosophical field that deals with problems arising when our actions affect the number or identity of individuals born in the future.
Antinatalism or anti-natalism is a philosophical view that deems procreation to be unethical. Antinatalists thus argue that humans should abstain from having children. Some antinatalists consider coming into existence to always be a serious harm. Their views are not necessarily limited only to humans but may encompass all sentient creatures, arguing that coming into existence is a serious harm for sentient beings in general.
Animal ethics is a branch of ethics which examines human-animal relationships, the moral consideration of animals and how nonhuman animals ought to be treated. The subject matter includes animal rights, animal welfare, animal law, speciesism, animal cognition, wildlife conservation, wild animal suffering, the moral status of nonhuman animals, the concept of nonhuman personhood, human exceptionalism, the history of animal use, and theories of justice. Several different theoretical approaches have been proposed to examine this field, in accordance with the different theories currently defended in moral and political philosophy. There is no theory which is completely accepted due to the differing understandings of what is meant by the term ethics; however, there are theories that are more widely accepted by society such as animal rights and utilitarianism.
Population ethics is the philosophical study of the ethical problems arising when our actions affect who is born and how many people are born in the future. An important area within population ethics is population axiology, which is "the study of the conditions under which one state of affairs is better than another, when the states of affairs in question may differ over the numbers and the identities of the persons who ever live."
Prioritarianism, or the priority view, is a perspective within ethics and political philosophy stating that "social welfare orderings should give explicit priority to the worse off". Prioritarianism resembles utilitarianism, and is likewise a form of aggregative consequentialism.
Larry Temkin is an American philosopher and Distinguished Professor Emeritus of philosophy at Rutgers University. Temkin’s research focuses on normative ethics and political philosophy, and his work has been highly influential, particularly his works Inequality and Rethinking the Good.
Negative utilitarianism is a form of negative consequentialism that can be described as the view that people should minimize the total amount of aggregate suffering, or that they should minimize suffering and then, secondarily, maximize the total amount of happiness. It can be considered as a version of utilitarianism that gives greater priority to reducing suffering than to increasing pleasure. This differs from classical utilitarianism, which does not claim that reducing suffering is intrinsically more important than increasing happiness. Both versions of utilitarianism hold that morally right and morally wrong actions depend solely on the consequences for overall aggregate well-being. "Well-being" refers to the state of the individual.
Negative consequentialism is a version of consequentialism, which is "one of the major theories of normative ethics." Like other versions of consequentialism, negative consequentialism holds that moral right and wrong depend only on the value of outcomes. That is, for negative and other versions of consequentialism, questions such as "what should I do?" and "what kind of person should I be?" are answered only based on consequences. Negative consequentialism differs from other versions of consequentialism by giving greater weight in moral deliberations to what is bad than what is good. Due to this, it can be considered an instance of what has been called "suffering-focused ethics", the view that the reduction of suffering has moral priority over any other possible duties we may think of.
The Asymmetry, also known as 'the Procreation Asymmetry', is the idea in population ethics that there is a moral or evaluative asymmetry between bringing into existence individuals with good or bad lives. It was first discussed by Jan Narveson in 1967, and Jeff McMahan coined the term 'the Asymmetry' in 1981. McMahan formulates the Asymmetry as follows: "while the fact that a person's life would be worse than no life at all ... constitutes a strong moral reason for not bringing him into existence, the fact that a person's life would be worth living provides no moral reason for bringing him into existence." Professor Nils Holtug formulates the Asymmetry evaluatively in terms of the value of outcomes instead of in terms of moral reasons. Holtug's formulation says that "while it detracts from the value of an outcome to add individuals whose lives are of overall negative value, it does not increase the value of an outcome to add individuals whose lives are of overall positive value."
Suffering-focused ethics are those views in ethics according to which reducing suffering is either a key priority or our only aim. Those suffering-focused ethics according to which the reduction of suffering is a key priority are pluralistic views that include additional aims, such as the prevention of other disvaluable things like inequality, or the promotion of certain valuable things, such as pleasure. Nevertheless, these views still prioritize reducing preventable suffering over these other aims.
Longtermism is the ethical view that positively influencing the long-term future is a key moral priority of our time. It is an important concept in effective altruism and a primary motivation for efforts that aim to reduce existential risks to humanity.
