Population Ethics Without Axiology: A Framework

This post introduces a framework for thinking about population ethics: “population ethics without axiology.” In its last section, I sketch the implications of adopting my framework for evaluating the thesis of longtermism.

Before explaining what’s different about my proposal, I’ll describe what I understand to be the standard approach it seeks to replace, which I call “axiology-focused.” (Skip to the section SUMMARY: “Population ethics without axiology” for a summary of my proposal.)

The axiology-focused approach goes as follows. First, there’s the search for axiology, a theory of (intrinsic) value. (E.g., the axiology may state that good experiences are what’s valuable.) Then, there’s further discussion on whether ethics contains other independent parts or whether everything derives from that axiology. For instance, a consequentialist may frame their disagreement with deontology as follows. “Consequentialism is the view that making the world a better place is all that matters, while deontologists think that other things (e.g., rights, duties) matter more.” Similarly, someone could frame population-ethical disagreements as follows. “Some philosophers think that all that matters is more value in the world and less disvalue (“totalism”). Others hold that further considerations also matter – for instance, it seems odd to compare someone’s existence to never having been born, so we can discuss what it means to benefit a person in such contexts.”

In both examples, the discussion takes for granted that there’s something that’s valuable in itself. The still-open questions come afterward, after “here’s what’s valuable.”

In my view, the axiology-focused approach prematurely directs moral discourse toward particular answers. I want to outline what it could look like to “do population ethics” without an objective axiology or the assumption that “something has intrinsic value.”

To be clear, there’s a loose, subjective meaning of “axiology” where anyone who takes systematizing stances[1] on moral issues implicitly “has an axiology.” This subjective sense isn’t what I’m arguing against. Instead, I’m arguing against the stronger claim that there exists a “true theory of value” based on which some things are “objectively good” (good regardless of circumstance, independently of people’s interests/​goals).[2]

(This doesn’t leave me with “anything goes.” In my sequence on moral anti-realism, I argued that rejecting moral realism doesn’t deserve any of the connotations people typically associate with “nihilism.” See also the endnote that follows this sentence.[3])

Note also that when I criticize the concept of “intrinsic value,” this isn’t about whether good things can outweigh bad things. Within my framework, one can still express beliefs like “specific states of the world are worthy of taking serious effort (and even risks, if necessary) to bring about.” Instead, I’m arguing against the idea that good things are good because of “intrinsic value.”

My alternative account, inspired by Johann Frick (who I’ll discuss more soon), says that things are good when they hold what we might call conditional value – when they stand in specific relation to people’s interests/​goals. On this view, valuing the potential for happiness and flourishing in our long-run future isn’t a forced move. Instead, it depends on the nature and scope of existing people’s interests/​goals and, for highly-morally-motivated people like effective altruists, on one’s favored notion of “doing the most moral/​altruistic thing.”

Outlook

In the rest of this post:

  • I give a summary of my framework

  • I warn the reader how it can be challenging to understand one another when discussing reasoning frameworks as opposed to object-level claims

  • I give examples of the “axiology-focused” /​ “something has intrinsic value” outlook from effective altruist writings (so readers get a good sense of what I’m arguing against)

  • I introduce two building blocks to underscore my framework: Johann Frick’s critique of the “teleological conception of well-being” and David Heyd’s idea that issues of creation/​procreation may be “outside the scope of ethics”

  • I introduce my framework at length (expanding on the summary; discussing applications; flowchart)

  • I mention some limits of my proposal and point to areas where further development seems necessary

  • I discuss the implications of my framework for evaluating longtermism (in short: all but the strongest formulations of longtermism still go through under plausible assumptions, but the distance between longtermism and alternative views shortens)

SUMMARY: “Population ethics without axiology”

  • Ethics is about interests/​goals.

  • Nothing is intrinsically valuable, but various things can be conditionally valuable if grounded in someone’s interests/​goals.

  • The rule “focus on interests/​goals” has comparatively clear implications in fixed population contexts. The minimal morality of “don’t be a jerk” means we shouldn’t violate others’ interests/​goals (and perhaps even help them where it’s easy and our comparative advantage). The ambitious morality of “do the most moral/​altruistic thing” coincides with something like preference utilitarianism.

  • On creating new people/​beings, “focus on interests/​goals” no longer gives unambiguous results:[4]

    • The number of interests/​goals isn’t fixed

    • The types of interests/​goals aren’t fixed

  • This leaves population ethics under-defined with two different perspectives: that of existing or sure-to-exist people/​beings (what they want from the future) and that of possible people/​beings (what they want from their potential creators).

  • Without an objective axiology, any attempt to unify these perspectives involves subjective judgment calls.

  • People with the motivation to dedicate (some of) their life to “doing the most moral/​altruistic thing” will want clear guidance on what to do/​pursue. To get this, they must adopt personal (but defensible), population-ethically-complete specifications of the target concept of “doing the most moral/​altruistic thing.”

  • Just like the concept “athletic fitness” has several defensible interpretations (e.g., the difference between a 100m sprinter and a marathon runner), so (I argue) does “doing the most moral/​altruistic thing.”

  • In particular, there’s a tradeoff where cashing out this target concept primarily according to the perspective of other existing people leaves less room for altruism on the second perspective (that of newly created people/​beings) and vice versa.

  • Accordingly, people can think of “population ethics” in several different (equally defensible)[5] ways:

    • Subjectivist person-affecting views: I pay attention to creating new people/​beings only to the minimal degree of “don’t be a jerk” while focusing my caring budget on helping existing (and sure-to-exist) people/​beings.

    • Subjectivist totalism: I count appeals from possible people/​beings just as much as existing (or sure-to-exist) people/​beings. On the question “Which appeals do I prioritize?” my view is, “Ones that see themselves as benefiting from being given a happy existence.”

    • Subjectivist anti-natalism: I count appeals from possible people/​beings just as much as existing (or sure-to-exist) people/​beings. On the question “Which appeals do I prioritize?” my view is, “Ones that don’t mind non-existence but care to avoid a negative existence.”

  • The above descriptions (non-exhaustively) represent “morality-inspired” views about what to do with the future. The minimal morality of “don’t be a jerk” still applies to each perspective and recommends cooperating with those who endorse different specifications of ambitious morality.

  • One arguably interesting feature of my framework is that it makes standard objections against person-affecting views no longer seem (as) problematic. A common opinion among effective altruists is that person-affecting views are difficult to make work.[6] In particular, the objection is that they give unacceptable answers to “What’s best for new people/​beings.”[7] My framework highlights that maybe person-affecting views aren’t meant to answer that question. Instead, I’d argue that someone with a person-affecting view has answered a relevant earlier question so that “What’s best for new people/​beings” no longer holds priority. Specifically, to the question “What’s the most moral altruistic/​thing?,” they answered “Benefitting existing (or sure-to-exist) people/​beings.” In that light, under-definedness around creating new people/​beings is to be expected – it’s what happens when there’s a tradeoff between two possible values (here: the perspective of existing/​sure-to-exist people and that of possible people) and someone decides that one option matters more than the other.

Ontology differences can impede successful communication

I see the axiology-focused approach, the view that “something has intrinsic value,” as an assumption in people’s ethical ontology.

The way I’m using it here, someone’s “ontology” consists of the concepts they use for thinking about a domain – how they conceptualize their option space. By proposing a framework for population ethics, I’m (implicitly) offering answers to questions like “What are we trying to figure out?”, “What makes for a good solution?” and “What are the concepts we want to use to reason successfully about this domain?”

Discussions about changing one’s reasoning framework can be challenging because people are accustomed to hearing object-level arguments and interpreting them within their preferred ontology.

For instance, when first encountering utilitarianism, someone who thinks about ethics primarily in terms of “there are fundamental rights; ethics is about the particular content of those rights” would be turned off. Utilitarianism doesn’t respect “fundamental rights,” so it’ll seem crazy to them. However, asking, “How does utilitarianism address the all-important issue of [concept that doesn’t exist within the utilitarian ontology]” begs the question. To give utilitarianism a fair hearing, someone with a rights-based ontology would have to ponder a more nuanced set of questions.

So, let it be noted that I’m arguing for a change to our reasoning frameworks. To get the most out of this post, I encourage readers with the “axiology-focused” ontology to try to fully inhabit[8] my alternative framework, even if that initially means reasoning in a way that could seem strange.

“Something has intrinsic value” – EA examples

To give readers a better sense of the “some things have intrinsic value” outlook and its prevalence, I’ll include examples from effective altruism.

From the Effective Altruism Forum Wiki article, Axiology:

Axiology, also known as theory of the good and value theory (in a narrow sense of that term), is a branch of normative ethics concerned with what kind of things and outcomes are morally good, or intrinsically valuable.

Clicking the hyperlink:

Intrinsic value (sometimes called terminal value) is the value something has for its own sake. Instrumental value is the value something has by virtue of its effects on other things.

From the Effective Altruism Forum Wiki article, Wellbeing:

Wellbeing (also called welfare) is what is good for a person, or what makes their life go well or is in a person’s interest. It is generally agreed that all plausible moral views regard wellbeing as having intrinsic value, with some views—welfarist views—holding that nothing but wellbeing is intrinsically valuable.

From the 80,000 Hours article, Longtermism: the moral significance of future generations:

However, the bottom line is that almost every philosopher who has worked on the issue doesn’t think we should discount the intrinsic value of welfare — i.e. from the point of view of the universe, one person’s happiness is worth just the same amount no matter when it occurs.

From the Utilitarianism.net website (written and maintained by effective altruists):

After all, when thinking about what makes some possible universe good, the most obvious answer is that it contains a predominance of awesome, flourishing lives. How could that not be better than a barren rock? Any view that denies this verdict is arguably too nihilistic and divorced from humane values to be worth taking seriously.

[...]

A core element of utilitarianism is welfarism—the view that only the welfare (also called well-being) of individuals determines how good a particular state of the world is. While consequentialists claim that what is right is to promote the amount of good in the world, welfarists specifically equate the good to be promoted with well-being.

The term well-being is used in philosophy to describe everything that is in itself good for someone—so-called intrinsic or basic welfare goods—as opposed to things that are only instrumentally good. For example, happiness is intrinsically good for you; it directly increases your well-being.

[...]

What things are in themselves good for a person? The diverging answers to this question give rise to a variety of theories of well-being, each of which regards different things as the components of well-being. The three main theories of well-being are hedonism, desire theories, and objective list theories.

Two building blocks

My alternative framework is based on two building blocks, which I’ll now introduce.

Against the teleological view of well-being – Johann Frick

This section draws from Johann Frick’s excellent paper Conditional Reasons and the Procreation Asymmetry.[9] Quotes by Frick show why I’m skeptical of “intrinsic value” and describe the type of account I’d replace it with.

To summarize, Frick criticizes the standard approach in population ethics for prematurely privileging an assumption, namely that well-being is something “to be promoted.” He points out that there’s an alternative: things matter conditionally because they’re grounded in someone’s interests/​goals. His view is best understood in contrast to what it criticizes – “the teleological conception of well-being:”

According to the teleologist, the appropriate response to what is good or valuable is to promote it, ensuring that as much of it exists as possible; the proper response to disvalue is to prevent it, or to ensure that as little of it exists as possible.

Some teleological thinkers, such as G.E. Moore, see such a close connection between goodness and its promotion that Moore often characterizes the good in terms of “what ought to exist”.

[...]

Next, note that viewing some value F as to be promoted implies that there is no deep moral distinction between increasing the degree to which F is realized amongst existing potential bearers of that value, and creating new bearers of that value.

[...]

By treating the moral significance of persons and their well-being as derivative of their contribution to valuable states of affairs, it reverses what strikes most of us as the correct order of dependence. Human wellbeing matters because people matter – not vice versa.

Frick also makes an analogy between procreation and promise-making: just like it’s good to keep promises if one makes them, the things that fulfill people’s interests/​goals are good if they (the people) are created.

Unlike Frick, I’m not advocating a particular normative theory, so I’m not saying the analogy between procreating and promise-making is the only way to think about the matter. My framework is compatible with (a subjectivist version of) totalism in population ethics (which doesn’t contain a procreation asymmetry). However, I concede that views with a procreation asymmetry become more viable options under Frick’s changed conception of well-being /​ why well-being matters.

Population ethics as “outside the scope of ethics” – David Heyd

I’ll discuss passages from David Heyd’s book Genethics to introduce the second building block. (The term “Genethics” never caught on – the field became known as “population ethics” instead.)

The Introduction to Heyd’s book is titled “Playing God” – an excellent perspective for illustrating the issues under discussion.

The question is whether value itself is attached only to human beings (or another defined group of moral subjects), or if it can also be ascribed to impersonal states of the world. If value can be attached only to moral subjects, then the question of their creation escapes value judgment. For how can the prehuman world be evaluated (as e.g., inferior to the world populated with human subjects) if there is in it no “anchor” to which value can be attached? [...] In terms of the story of creation, when God sees that everything he had made was “very good,” is it very good for him, very good for created humanity, or very good simpliciter?

Heyd’s last sentence captures a core component of my proposal. Following Frick’s point that value is conditional value (no objective axiology; no grounding perspective from which to evaluate what’s “good simpliciter”), we’re left with two different perspectives. First, that of existing people/​beings (in Heyd’s example, God all by himself). Second, that of possible people/​beings (here: humanity, perhaps alongside other possible civilizations God could have contemplated creating). The last perspective Heyd discusses, that of “good simpliciter,” is non-existent.

Heyd also made some noteworthy observations on methodological challenges:

Not to know the answer to an important question is bad enough. Not to know how to go about solving it is even worse. [… I]t seems that they [“Genesis problems,” i.e., matters of creation of new people/​beings] also prompt a sense of methodological uneasiness, raising doubts concerning the definition and scope of basic ethical concepts, the validity of certain methods of justification in ethical argumentation, and indeed the very limits of ethics.

Indeed, another core claim in my framework is that there are issues within population ethics for which there’s no objective answer.

“Population ethics without axiology”

I’ll now sketch my framework. I’ll proceed in the following order.

  • Background assumptions and (further) building blocks

    • Complements and elucidates the points from the summary (here’s the link in case you want to re-read it)

  • Caring about the future: a flowchart

    • Visualizes the workings of my framework and its option space

  • Applications (examples)

    • Ideas for filling in further assumptions when applying the framework

Background assumptions and (further) building blocks

Ethics is about interests/​goals.

“Outside the scope of (normal) ethics.”

  • In my ontology, “population ethics” is no longer a crisp domain with a single answer. Instead, it has areas where the approach “focus on interests/​goals” leaves things under-defined. These include “How to unify the two perspectives – that of existing people and that of newly(-to-be-) created people?” and “To the degree that we care about what’s best for possible people, which appeals should we prioritize when we cannot do right by everyone?”

How do we know the views of possible people?

  • We can’t talk to not-yet-existing people. When I discuss what possible people/​beings want, I imagine a scenario where they come to exist and we ask them questions about how they’d compare their existence to a hypothetical where they had never been born. (If you think this approach is very subjective – that’s partly my point.)

There’s a tension between the beliefs “there’s an objective axiology” and “people are free to choose their life goals.”

  • Many effective altruists hesitate to say, “One of you must be wrong!” when one person cares greatly about living forever while the other doesn’t.[10] By contrast, when two people disagree on population ethics “One of you must be wrong!” seems to be the standard (implicit) opinion. I think these two attitudes are in tension. To the degree people are confident that life goals are up to the individual to decide/​pursue, I suggest they lean in on this belief. I expect that resolving the tension in that way – leaning in on the belief “people are free to choose their life goals;” giving up on “there’s an axiology that applies to everyone” – makes my framework more intuitive and gives a better sense of what the framework is for, what it’s trying to accomplish.

Minimal morality vs. ambitious morality.

  • My framework creates space for a distinction between minimal morality and ambitious mortality.

  • Minimal morality is “don’t be a jerk” – it’s about respecting that others’ interests/​goals may be different from yours. It is low-demanding, therefore compatible with non-moral life goals. It is “contractualist”[11] or “cooperation-focused” in spirit, but in a sense that stays nice even without an expectation of reciprocity.[12]

  • Ambitious morality is “doing the most moral/​altruistic thing.” It is “care-morality,” “consequentialist” in spirit. It’s relevant for morally-motivated individuals (like effective altruists) for whom minimal morality isn’t demanding enough.

  • That said, minimal morality isn’t just a low-demanding version of ambitious morality. In many contexts, it has its own authority – something that wouldn’t make sense within the axiology-focused framework. (After all, if an objective axiology governed all aspects of morality, a “low-demanding” morality would still be directed toward that axiology.)[13] In my framework, minimal morality is axiology-independent – it protects everyone’s interests/​goals, not just those of proponents of a particular axiology.

  • Admittedly, there are specific contexts where minimal morality is like a low-demanding version of ambitious morality. Namely, contexts where “care-morality” and “cooperation-morality” have the most overlap. For instance, say we’re thinking about moral reasons towards a specific person with well-defined interests/​goals and we’re equal to them in terms of “capability levels” (e.g., we cannot grant all their wishes with god-like power, so empowering them is the best way to advance their goals). In that scenario, “care-morality” and “cooperation-morality” arguably fall together. Since it seems reasonable to assume that the other person knows what’s best for them, promoting their interests/​goals from a cooperative standpoint should amount to the same thing as helping them from a care/​altruism standpoint.[14]

  • Still, cooperation-morality and care-morality come apart in contexts where others’ interests/​goals aren’t fixed:
    (1) Someone has under-defined interests/​goals.
    (2) It’s under-defined how many people/​beings with interests/​goals there will be.
    (3) It’s under-defined which interests/​goals a new person will have.
    In such contexts, cooperation-morality says “pick a permissible option.” Highly-morally-motivated people will likely find that unsatisfying and want to go beyond it. Instead of “let’s not be jerks,” they want to do what’s best for others. They want (ambitious) care-morality: to figure out and apply what it means to “do the most moral/​altruistic thing.”

  • Without an objective axiology, this target concept is under-defined. Accordingly, different(ly)-morally-motivated people may fill in the gaps in different ways. At first glance, this looks like it could create tensions.

  • However, because minimal morality has its own authority, altruists with different conceptions of ambitious morality should endorse “don’t be jerks” towards each other, too. When we look at the motivation to develop and adopt some ambitious morality, that motivation doesn’t say minimal morality is wrong – only that it’s incomplete. Effective altruists want to go beyond minimal morality, not against it.

  • Where people have well-specified interests/​goals, it would be a preposterous conception of care-morality to stick someone into an experience machine against their will or kill them against their will to protect them from future suffering. So, whenever a single-minded specification of care-morality (e.g., “hedonistic utilitarianism” or “negative utilitarianism”) contradicts someone’s well-specified interests/​goals, that type of care-morality seems misapplied and out of place.

  • Because ambitious morality is under-defined only in places where people’s interests/​goals are under-defined, everything works out fine: Different morally-motivated individuals may come away with different specifications of ambitious morality, but they never endorse violating minimal morality.

Why specify ambitious morality at all?

  • If ambitious morality is under-defined, why not leave it at that? Why fill in the gaps with something subjective – doesn’t that go against the spirit of our motivation to “pursue what’s moral”?

  • Just like the concept “athletic fitness” has multiple defensible interpretations (e.g., the differences between a 100m sprinter, a marathon runner, and someone who exercises to minimize cardiovascular risks),[15] so does “doing the most moral/​altruistic thing.” Suppose your childhood dream was to be ideally athletically fit. In that case, whether you should care about a specific interpretation of the target concept or embrace its under-definedness is an open question. My advice for resolving this question is “think about which aspects of fitness you feel most drawn to, if any.”[16]

Population ethics from the perspective of existing people.

  • Envision technologically-very-developed settlers standing in front of a giant garden: There’s all this unused land and a long potential future ahead of them – what do they want to do with it? How do they address various tradeoffs (e.g., risks of creating dystopian subcommunities)? From the perspective of existing people, population ethics is about figuring out how much we care about the long-run future (if at all) and what we want to make of it. I see this as more of an existentialist question (about meaning/​purpose) than a moral one – though it becomes “also moral” for individuals who want to dedicate their lives to “doing the most moral/​altruistic thing.”

Population ethics from the perspective of possible people.

  • Newly created beings are at the whims of their creators (e.g., children are vulnerable to their parents). However, “might makes right” is not an ideal even minimally-morally-inclined creators would endorse. We can view population ethics from the perspective of possible people/​beings as a court hearing: possible people/​beings speak up for their interests/​goals. With potential creators who are only following the minimal morality of “don’t be jerks,” the possible people/​beings must resort to complaints to hold their creators accountable. By contrast, towards altruistically-motivated potential creators, they can also make appeals.

Complaints vs. appeals.

  • Complaints: Something counts as a complaint if someone who cares about fairness (“don’t be a jerk”) cannot defensibly ignore your complaint – even if their goals otherwise don’t include concern for your well-being.

  • Appeals: Anything you want to ask of someone who is already motivated to benefit you.

  • Minimal morality applied to possible people/​beings is about avoiding complaints; ambitious morality applied to them is about granting appeals. Because different possible people/​beings make different appeals,[17] ambitious morality focused on possible people/​beings is under-defined – specifying it requires further (“axiological”) judgment calls.

The tradeoff between benefiting sure-to-exist people/​beings vs. possible people/​beings.

  • In the summary, I wrote, “Cashing out that target concept [doing the most moral/​altruistic thing] primarily according to the perspective of existing (and sure-to-exist) people leaves less room for altruism on the second perspective (that of possible people) and vice versa.”

  • By this, I mean we have to choose one or the other. Either our ambitious morality is primarily about existing (and sure-to-exist) people/​beings, or we also want what’s best for possible people/​beings. (While the latter doesn’t give possible people/​beings more weight, the large numbers at stake will dominate in practice.)[18]

Caring about the future: a flowchart

Applications (examples)

I’ll now give some examples for applying my framework. I’m not particularly attached to any specifics. Instead, I’m mostly arguing in favor of a particular way of thinking about such principles, e.g., how to apply them, their reach, etc.

Population ethics for possible people/​beings: applying the court hearing analogy

In my framework, population ethics for possible people/​beings is like a court hearing where possible people/​beings address their potential creators.

Creators interested in minimal morality can only be held accountable via complaints (i.e., possible people object they didn’t receive even the minimal consideration of “don’t be a jerk”).

Complaints examples:

  • Don’t create minds that regret being born.

  • Don’t create minds and place them in situations where their interests are only somewhat fulfilled if you could easily have provided them with better circumstances.

  • Don’t create minds destined for constant misery even if you also equipped them with a strict preference for existence over non-existence.

Note that these principles aren’t meant to be absolutes. Instead, there’s an implicit “unless you acted according to a defensible conception of what’s best for possible people/​beings.”[19]

By contrast, potential creators dedicated to some (non-person-affecting) ambitious morality are motivated to benefit possible people/​beings well beyond “avoiding complaints” – they want to hear out possible people/​beings to learn what’s best for them.

Appeals might go like this:

  • Possible person A: Maximize my chances of coming into existence with a favorable life trajectory; I’m okay running some risk of landing in an unfavorable one.

  • Possible person B: Minimize my chances of coming to exist with an unfavorable life trajectory; compared to my non-existence, I wouldn’t feel grateful about coming to live.

Examples of minimal morality vs. ambitious morality

To illustrate the distinction, I’ll give examples of common-sense statements about the ethics of procreating/​having children. I justify each statement via one of three principles:

  • Minimal morality

  • Ambitious morality

  • “People can choose their own goals”

Examples:

  • People are free to decide against becoming parents (“people can choose their own goals”).

  • Parents are free to want to have as many children as possible (“people can choose their own goals”), as long as the children are happy in expectation (“minimal morality”).

  • People are free to try to influence other people’s moral stances and parenting choices (“people can choose their own goals”) – for instance, Joanne could promote anti-natalism and Marianne could promote totalism (two different specifications of “ambitious morality”) – as long as their persuasion attempts remain within the boundaries of what is acceptable in a civil society (“minimal morality”).

  • All parents must provide a high degree of care for their children (“minimal morality”).

For comparison, readers may (on their own) think about how these examples would work within the axiology-focused framework, where the answer is usually some form of “it depends on the correct axiology.”

(In)famous population ethics problems

I’ll now sketch how one could apply my approach to familiar questions/​issues in population ethics. One thing I want to highlight is how the distinction between minimal morality and ambitious morality can motivate person-affecting views (“ambitious morality focused on benefitting existing and sure-to-exist people/​beings; minimal morality for possible people/​beings.”)

Procreation asymmetries.

  • Minimal morality for possible people/​beings contains a weak procreation asymmetry because “don’t create minds that wish they had never been born” is generally less morally demanding than “create happy minds who will be grateful for their existence.”[20] Arguably, it also contains a procreation asymmetry for the more substantial reason that creating a specific person singles them out from the sea of all possible people/​beings in a way that “not creating them” does not.[21]

  • Ambitious morality comes in different specifications, some of which contain a procreation asymmetry, others don’t.

    • Subjectivist person-affecting views import the procreation asymmetry from minimal morality to possible people/​beings while focusing their caring budget on existing (and sure-to-exist) people/​beings. (“Preference utilitarianism for existing and sure-to-exist people/​beings; minimal morality for possible people/​beings.”)

    • Subjectivist (versions of) totalism and anti-natalism care about what’s best for possible people/​beings, but they’re built on different accounts of how to best benefit this interest group.[22] (They follow minimal morality for existing and sure-to-exist people/​beings.)

The transitivity of “better-than relations.”

  • According to minimal morality, it’s neutral to create the perfect life and (equally) neutral to create a merely quite good life. Treating these two outcomes equally seems incompatible with doing what’s best for newly created people/​beings. However, minimal morality isn’t about “doing the most moral/​altruistic thing,” so this seems fine.

  • For any ambitious morality, there’s an intuition that well-being differences in morally relevant others should always matter.[23] However, I think there’s an underappreciated justification/​framing for person-affecting views where these views essentially say that possible people/​beings are “morally relevant others” only according to minimal morality (so they are deliberately placed outside the scope of ambitious morality).

Independence of irrelevant alternatives (IAA).[24]

  • Same as above: both minimal morality and person-affecting views tend to violate the transitivity of better-than-relations or IAA (or both). For minimal morality, this is arguably fine because the goal isn’t to maximally benefit. For person-affecting ambitious morality, this is arguably fine because the view concentrates its caring budget on existing and sure-to-exist people/​beings.

The repugnant conclusion.[25]

  • It makes a difference whether to turn an existing paradise-like population into a much larger, less happy-on-average population vs. whether we’re comparing two options for colonizing a far-away galaxy with new people/​beings.[26]

  • In the first version of the repugnant conclusion, minimal morality toward sure-to-exist people prohibits lowering the life quality in the paradise-like population (unless sufficiently many paradise-inhabitants would endorse the change), so there’s no ambitious morality that could justify the repugnant conclusion here.

  • In the second version, different specifications of ambitious morality will give widely differing answers, ranging from “the smaller population is preferable” to “it doesn’t matter” or “it depends on how other existing people feel about the matter” to “the larger population is preferable.”

The pinprick argument.[27]

  • Same as above. It makes a difference whether to extinguish an existing paradise-like population because of a pinprick of discomfort/​suffering vs. whether we’re contemplating the creation of a new paradise-like population (with a pinprick).

  • In the first version, minimal morality towards sure-to-exist people prohibits bringing about extinction.

  • Even in the second version, minimal morality towards sure-to-exist people arguably demands creating the paradise-like population.[28]

The non-identity problem.[29]

  • The non-identity problem remains tricky for minimal morality and person-affecting versions of ambitious morality.

  • I don’t feel like I have an optimal answer – the court hearing analogy leaves things under-defined.[30]

  • One pathway I find promising is thinking less about harming/​benefitting a specific individual and more about whether we’re lending (sufficient) care/​concern to the interests of newly created people/​beings. As an interest group, the latter have their interests violated if someone creates mediocre-life-trajectory Cynthia instead of great-life-trajectory Ali, even if Cynthia herself wasn’t harmed.

  • Some recent work in population ethics explores similar directions; see this paper by Teruji Thomas or this one by Christopher Meacham (discussed here on the EA forum).[31]

Limitations and open questions

Now that I’ve described my framework, I want to note some of its limitations.

  • The exact reach of minimal morality is fuzzy/​under-defined. How much is entailed by “don’t be a jerk?”

I haven’t provided any attempt to answer precisely how far-reaching minimal morality is, so I understand that my proposal may seem unsatisfying. That said, I think this sort of under-definedness[32] is okay –lots of things in ethics seem fuzzy.

  • The exact nature of (and justification for) minimal morality could be clearer.

While polishing this post, I read Richard Ngo’s new post Moral strategies at different capability levels. I found his framing illuminating and have tried to incorporate it in my post, but mostly with late-stage edits instead of some more principled approach.

  • The non-identity problem doesn’t yet have a satisfying answer within my framework.

    • (See my discussion in the previous section.)

I doubt that coming up with any specific solution to non-identity issues would change the practical priorities of effective altruists, but further work on this topic could help evaluate whether I’m perhaps shrugging deeper problems with my framework under the carpet.[33]

  • I don’t give a precise account of what it is about interests/​goals that makes something conditionally valuable.

With my framework, I endorse some version of a “preference-based view,” but there are many different versions of that.[34] Working out a more concise theory of conditional value could be useful for further assessing my framework.

Recommendations for longtermists

In this EA forum post, Will MacAskill defines “longtermism” as follows:[35]

Longtermism is the view that positively influencing the longterm future is a key moral priority of our time.

Based on my framework, I have the following recommendations for people interested in evaluating or promoting longtermism:

  • Highlight the existence of alternative frameworks (alternatives to “something has intrinsic value”).
    First off, my framework proposal is just that, a proposal. I don’t expect all longtermists to adopt it. Still, the framework seems valid to me. So far, many longtermists frame the discussion as though there’s no alternative to “something has intrinsic value.”

  • Asking/​caring about how much other people care about long-run outcomes.
    In the axiology-focused framework, the degree to which longtermism applies is primarily a philosophical question (though the causal reach of our actions also matters). Also, when longtermism “applies,” it applies equally to everyone interested in moral action. By contrast, within my framework, the degree(s) to which longtermism applies can depend on existing people’s attitudes towards the long-run future.[36] I think there’s something justifiably off-putting about discussions of longtermism that neglect this perspective. For what it’s worth, I suspect that a non-trivial portion of people outside effective altruism care about long-run outcomes a great deal – just that they maybe care about them in ways that don’t necessarily reflect totalism/​thorough-going aggregation for newly created people/​beings. Overall, I see multiple benefits – both strategic (how longtermism is perceived) and normative (deciding between different degrees of “longtermism applies”) – to asking and caring about how others care about the long-run future.

  • Emphasizing more the ways ethics is (likely) subjective.
    When arguing in favor of (some version of) longtermism, I recommend flagging the possibility that there may not be an objective answer. Instead, I’d say something like the following. “Longtermism is a position many effective altruists endorse after contemplating what’s entailed by their motivation/​commitment to ‘do the most good’. Here’s why: [Arguments that aim to appeal to people’s fundamental intuitions.]” (Another way of saying this is “encourage others to join by telling them what sort of future you’re fighting for and why.”)[37]

  • Treating person-affecting views more fairly?
    EA discourse about person-affecting views has sometimes been crude or overly simplistic.[38] I think the following angle on person-affecting views is underappreciated: “preference utilitarianism for existing (and sure-to-exist) people/​beings, minimal morality for possible people/​beings.” I agree that person-affecting views don’t give satisfying answers to “what’s best for possible people/​beings,” but that seems fine! It’s only within the axiology-focused approach that a theory of population ethics must tell us what’s best for both possible people/​beings and for existing (or sure-to-exist) people/​beings simultaneously.

    Quoting from this summary: In theism vs. atheism debates, atheists don’t replace ‘God’ with anything when they stop believing in him. By contrast, in realism vs. anti-realism debates, anti-realists continue to think there’s “structure” to the domain in question. What changes is how they interpret and relate to that structure. Accordingly, moral anti-realism doesn’t mean “anything goes.” Therefore, the label “nihilism,” which some people use synonymously with “normative anti-realism,” seems uncalled for. The version of anti-realism I defend in my sequence fits the slogan “Morality is ‘real’ but under-defined.” Under-definedness means that there are multiple defensible answers to some moral issues. In particular, people may come away with different moral beliefs depending on their evaluative criteria, what they’re interested in, which perspectives they choose to highlight, etc. Overall, the way some moral philosophers use “nihilism” interchangeably with “anti-realism” seems surprisingly unfair. Imagine if, in the free will debate, the proponents of libertarian free will pretended that compatibilist positions didn’t exist, that the only alternative to libertarian free will was “It makes no difference if you look left and right before crossing the street.”

    Technically, interests/​goals aren’t necessarily fixed in fixed population contexts either, since we can imagine people with under-defined goals or goals that don’t mind being changed in specific ways.

  5. ↩︎

    Readers may wonder why I’m confident that several interpretations are “equally defensible” as opposed to “the jury is still out.” I concede that I’m not certain. Still, “equally defensible interpretations” are my default view, whereas “there’s a single moral truth” would be a surprising discovery. Because of the is-ought problem, we have to “get normativity started” by stipulating some assumptions on what we care about. What makes up a “defensible interpretation of a domain” depends on the features we choose to highlight. (See Luke Muehlhauser’s post on Pluralistic Moral Reductionism or my discussion of “evaluation criteria” in various places along my moral anti-realism sequence.) In my framework, I highlight that “morality” seems to be about interests/​goals. We can see why this framing has ambiguous applications in contexts where interests/​goals aren’t fixed. Since I don’t see any uncontroversial/​uncontested extension principles, it stands to argue that population ethics will remain under-defined. Sure, there’s a remote chance that a future philosopher will devise a brilliant argument that convinces everyone to adopt a particular normative theory. However, that seems far-fetched. (And even then, we could wonder if maybe that philosopher just happened to be good at rhetoric or that people’s moral intuitions became more homogenous in the meantime for reasons unrelated to normative truth.)

    For instance, Hilary Greaves (2017), on the neutrality required for asymmetric person-affecting views (where creating a miserable person is bad but failing to create a happy person is neutral), writes that “it turns out to be remarkably difficult to formulate any remotely acceptable axiology that captures this idea of ‘neutrality’.”

    We can distinguish between “low-demanding” and “high-demanding” versions of contractualism. Minimal morality is low-demanding contractualism. By contrast, “high-demanding contractualism” would demand from everyone to exclusively follow altruistic goals.

  12. ↩︎

    In other words, I’m not talking about cooperation that’s optimally beneficial even for self-oriented goals. Instead, I’m mainly appealing to the pro-social instinct to follow fairness norms – which we can extend to fairness to animals or future generations, despite knowing that these interest groups cannot reciprocate.

  13. ↩︎

    For instance, if hedonist axiology was objectively correct, then we could think of classical utilitarianism as “ambitious morality,” while “minimal morality” would be something like “the set of not-too-demanding social norms that produce the best consequences from a classical utilitarian perspective.”

  14. ↩︎

    One caveat here is that people may have self-sacrificing goals. For instance, say John is an effective altruist who’s intent on spending all his efforts on making the world a better place. Here, it seems like caring about “John the person” comes apart from caring about “John the aspiring utilitarian robot.” Still, on a broad enough conception of “interests/​goals,” it would always be better if John was doing well himself while accomplishing his altruistic goals. I often talk about “interests/​goals” instead of just “goals” to highlight this difference. (In my vocabulary, “interests” aren’t always rationally endorsed, but they are essential to someone’s flourishing.)

    I also give further-reaching and more nuanced advice on how to think about issues related to “moral uncertainty,” “metaethical uncertainty,” etc., in my post The “Moral Uncertainty” Rabbit Hole, Fully Excavated.

    For instance, some possible people would rather not be created than be at a small risk of experiencing intense suffering; others would gladly take significant risks since they care immensely about the chance of a happy existence.

  18. ↩︎

    Since ambitious morality fills the gaps of minimal morality rather than overriding it, someone with an (in practice) “future-focused” view would still interact with existing and sure-to-exist people within the bounds of the social contract from minimal morality, even though there’s a sense in which “much more is at stake” for possible people/​beings.

  19. ↩︎

    For instance, someone who endorses subjectivist totalism as their ambitious morality could create a much larger number of slightly-happy individuals instead of a small number of very happy individuals without thereby violating the spirit of the second principle above. Their defense would be that they acted on a defensible notion of what’s best for possible people/​beings (in aggregate, as an interest group).

    In typical circumstances, many courses of action are compatible with not pushing a child into a pond, whereas only one type of action is compatible with rescuing an already-drowning child. See this post by Katja Grace, who noted that person-affecting views structurally resemble the action-omission distinction around property rights.

  21. ↩︎

    If I fail to create a happy life, I’m acting suboptimally towards the subset of possible people who’d wish to be in that spot – but I’m not necessarily doing anything to highlight that particular subset. (Other possible people who wouldn’t mind non-existence and others yet would want to be created, but only under more specific conditions/​circumstances.) By contrast, when I make a person who wishes they had never been born, I singled out that particular person in the most real sense. If I could foresee that they would be unhappy, the excuse “Some other possible minds wouldn’t be unhappy in your shoes” isn’t defensible.

    Some existing people would (presumably) greatly prefer the paradise-population to come into existence, which seems a good enough reason for minimal morality to ask of us to push that button. (Minimal morality is mostly about avoiding causing harm, but there’s no principled reason never to include an obligation to benefit. The categorical action-omission of libertarianism seems too extreme! If all we had to do to further others’ goals were to push a button and accept a pinprick of disvalue on our ambitious morality, we’d be jerks not to press that button.)

    As a side note, there’s a version of the non-identity problem where, instead of focusing on differences between people’s identities, we focus on differences between people’s types of interests/​goals. Let’s say we create grateful-to-exist Ramon instead of detached-from-life Nadieshda. We did well by Ramon’s standards, even though Nadieshda would have counted as neutral in the same life trajectory. In a sense, we only benefitted Ramon because we got lucky that he felt like he was benefitted. Or maybe we even deliberately created him with the type of psychology that could be benefited this way. Is this okay? I’d say yes to some degree because we cannot act without implicitly influencing the interests of the people we create (and leaving things up to chance would be worse). However, it seems objectionable to use this in our favor to exploit newly created people and give them worse life circumstances.

    There’s a relevant difference between something being under-defined in the sense of having fuzzy boundaries vs. under-defined in the sense of “depending on how you specify this, you end up with opposite answers to decision problems like the repugnant conclusion, etc.

    At the extreme, I remember framings that went like this. “Do you think the welfare of people in the future should be discounted, yes or no? If you think no, then you favor totalism in population ethics. Footnote: Some people also have person-affecting views but these are widely regarded to run into unworkable problems.”
