Longtermism: An Impracticable Attempt to Reason Our Way into Becoming Irrationally Generous Heroes?

“If we recognise that it is a part of human nature to be prepared to sacrifice for others principally through emotive relationships and a lived experience of solidarity and empathy, we are left facing the awkward reality that, as a facet of cosmic complexity, utilitarianism, so well equipped to recognise the need to develop our relationship with future generations, may not be well equipped to do much about it.”


A common frustration for those visiting Rome is the impossibility of seeing everything. Even those committed to score-of-thousand stepped and stomach-stretching days merely scratch at the interwoven cultural strands densely packed over millennia into a hard surface. This is one reason why I am grateful for having studied there, eight years being time enough to reach a working familiarity with the city’s seemingly endless sources of spiritual, aesthetic, and earthly refreshment. My last weeks in the eternal city, then, were not spent frantically completing a ‘Things to Do in Rome’ list but rather making the most of a different opportunity. As a freshly minted Roman Catholic priest who had read Toby Ord’s ‘The Precipice’, I was trying to develop my piqued curiosity from the muddled acknowledgement of the importance of the issues raised into a PhD proposal. I was grateful also, then, for the chance to seek out advice from some of the big, (relatively speaking), names of Catholic theology that can be found in Rome. These conversations included a memorable one-liner which is as simple as it is disarming: “Ah, those Oxford academics: they couldn’t even stop Brexit, what makes them think they can stop the end of the world?”

Whilst this may, at first, appear to be an uncharitable dismissal from social conservatism and exactly the sort of sense-of-an-end-assuring apocalypticism Thomas Moynihan explains so admirably (Moynihan 2020, 33), my theological master makes no immediate moral claim. The criticism raises more general questions about how moral philosophy is communicated and whether the way in which we think might introduce limitations to our capacity to invite others to share in our conclusions.

Such issues are not irrelevant to social-political commentary in a post-2016 world which cannot be recreated here, however it should suffice to say that, if the general voting public responds to big questions in a way that surprises or, dare we say, at times frustrates those who have opportunity to engage with those questions more fully, advocates of Longtermism have a Public Relations challenge ahead of them. This essay, then, hopes to point to the apparent absence of addressing such considerations in the recently published compendium Essays on Longtermism. To be clear; I am not criticising the compendium itself for not being more accessible to the general public, (that is evidently not its intended audience), however it appears to neglect study of some inherent challenges which future publications intended for public engagement, building on the efforts of Ord’s “The Precipice” or MacAskill’s “What we Owe the Future”, would need to face.

In the following summary of some of these challenges, I assume that a moderate form of Longtermism is, in principle, uncontroversial. I concur with the simple claim by Owen Cotton-Barratt and Rose Hadshar that most people agree that future people matter. (Cotton-Barratt and Hadshar 2025, n. 2) Likewise, as I cast my mind over several years of speaking about my own PhD research, I do not recall anyone objecting to the basic idea of the Hinge of History; that the coming chapter of human history is characterised by the novel challenge of learning to mitigate hazards we create for ourselves. This would mean, gratefully receiving Charlotte Franziska Unruh’s helpful note that causing harm is intuitively worse than not producing benefit (Unruh 2025, 146), it is not ultimately all that controversial, in principle, that it is a moral good to safeguard future generations from the harms that we ourselves might otherwise cause.

If the principle of such moderate Longtermism is, in fact, relatively uncontroversial, we rightly wonder why society is so myopic. There appears to be a gap between initial moral judgement and concrete action. This is problematic if the effective mitigation of existential risks requires a broader societal acceptance of Longtermist attitudes. There is already a gap between acknowledging the present poverty and suffering around the world, and the apparent inactivity of those who would be able to help. Things only get harder when the future becomes involved, if only because policies that rebalance resource expenditure away from addressing near-term needs towards the benefit of future generations, experienced as sacrifice, do not help win elections. In debates, loops can form as discourse passes back and forth between two negative states; from resisting the acceptance of significant new responsibilities to intuited concern about what it might mean in practise if such responsibilities are not fulfilled. How might that loop be disrupted? What solutions are forthcoming towards overcoming resistance, either in populations or in high-powered individuals, to working towards climate sustainability, better regulated Artificial Intelligence development and biotechnological development, or nuclear disarmament? When such a barrier is perceived between judgement and action, one instinct is further to clarify the judgement in the hope that making a stronger case can overcome uncertainty. I would argue, however, that there appear to be two obstacles to this approach in the case of advocating for safeguarding future generations on utilitarian terms, suggesting that a point of diminishing returns may have already been reached for further developing the philosophical case for forms of Longtermism strong enough to make some difference.

As a first observation: If the case for safeguarding future generations requires the depth and nuance present in the collections of articles this essay is responding to, then we might well despair as it is difficult to foresee a future of broader public discourse that could effectively operate at that level. Fortunately, as already noted, I do not believe that promoting Longtermism requires such depth of argumentation. It is not as if there are crowds of people who are waiting, for example, for non-fanatical decision theory to develop sufficiently to see if the high price asked by longtermism is definitely worth paying before allowing Longtermist principles to shape their decision making. (C.f. Greaves and MacAskill 2025, 38)

The first challenge I would identify, then, is acknowledging that reaching deeper into moral rationalism creates stronger moral motivation only for a certain personality type. The friend who introduced me to Effective Altruism once said: “One of the problems we have is that educated people who like graphs are good at convincing other educated people who like graphs, but not necessarily anyone else.” To express this more formally: There are the sorts of people who are intuitively motivated by rationally deducing a requirement to do something, but the strength of this response varies. Moral motivation in utilitarianism generally comes both from an assumption that acting in a way that maximises the good for society will also attain a good for the agent, as well as, sharing ground with deontological thought, through an emotional experience that can arise when moral judgements are made which bring a duty into relief. (de Colle and Werhane 2008, 751) However, it is possible to argue that many do not have as strong an emotional response to the recognition of duties, or the possibility of maximising abstract goods, as Longtermism requires. In this case, something other than developing moral arguments further still will be required to promote Longtermism amongst those who do not respond to such arguments with sufficient emotion to overcome affections for self, family, and tribe to a sufficient degree to sacrifice for others who are distant across space and time.

This motivational challenge is intensified as the nature of future ethics disrupts auxiliary sources of motivation that ethics can rely on in present application. (Birnbacher 2012, 276) When looking to the future, moral judgements do not have recourse to the experience of present situations which generates friction within ethical frameworks developed with contemporary relationships in mind. This is why Longtermist claims begin to strain to the limit ethical approaches which otherwise rely on empathy and solidarity for motivating concrete action. I would argue there is something amiss in assumptions, often encountered in the literature, that Longtermism is but a further step of an expansion of our circle of moral concern to include future generations, failing to recognise the particularity of future ethics. Previous developments in societal norms were supported by a vicinity to harm caused: the tragedy of human slavery can be seen, activist for animal welfare can show footage of great animal suffering, and other forms of contemporary injustice create visible injury by which we, in good conscience, are repulsed. This repulsion is greatly diminished when contemplating future harms and so the next step of moral expansion cannot rely on what has worked elsewhere. Likewise, whilst it is true that, in the past, the emotive effects of ongoing war led populations to accept the loss of certain prerogatives, such as the consumption of luxuries, it is a mistake to apply this directly to future ethics, expecting the possibility of future harm to illicit a comparable response. (C.f. Greaves and MacAskill 2025, 40; Kitcher 2025, 209)

I have so far proposed that the obstacles to promoting Longtermism exist on a level of emotional bonds, rather than of uncertainty of moral argumentation, and that there are at least two inherent weaknesses to promoting greater responsibilities for the future through moral argumentation; disruptions to moral motivation that come from variations in emotional response to rationally deduced responsibilities and the unavailability of experience of future harm as a source of empathy. If we recognise that it is a part of human nature to be prepared to sacrifice for others principally through emotive relationships and a lived experience of solidarity and empathy, we are left facing the awkward reality that, as a facet of cosmic complexity, utilitarianism, so well equipped to recognise the need to develop our relationship with future generations, may not be well equipped to do much about it.

Reading ‘Essays on Longtermism’ with this in mind reframes epistemic humility into a lack of aspiration. Kitcher copes with myopia and speculates what the world might look like if it was filled with ‘unusually thoughtful, other directed, and public-spirited people’ but does not consider how we move together in that direction. (Kitcher 2025, 207–8) Challenges such as bias, partiality, and myopia are understood and modelled but little is proposed in terms of exploring the deeper root causes within the human experience and how they might be overcome. Owen Cotton-Barrat and Rose Hadshar describe what Longtermist societies might look like to a lesser or greater degree, but not what can be done to make a state more or less Longtermist, other than rather dystopian scenarios of a coercive state with a strict commitment to Longtermism, ruling over a people that does not share its views. (Cotton-Barratt and Hadshar 2025) The concept of Cultural Evolution is not applied to a possible greater spread of Longtermism itself, neglecting to describe the possible persistence of valuing future goods and recognising a moral relationship with future generations.(Vallinder 2025, 251) Riedener considers how the temporal gap disrupts authenticity of action, but not how values and intuitions which determine authenticity can develop and be promoted to enable authentic concern for future generations. (Riedener 2025, 155)

The question then arises: what would it look like for Longtermism not to see ‘common moral intuitions’ as an issue, a source of objections on the grounds of fanaticism, (C.f. Askell-Barratt and Neth 2025) but something that can be developed in a favourable way? What impact could be made by rigorous and wider-reaching studies of how we might inspire others to change the way they live their lives, not by being even more certain about the judgement, but by considering the required middle stage of moral motivation that enables action, especially sacrifice for others? (This could be of benefit if only because of political figures who are content to leverage the stronger emotional response of near-term needs for electoral benefit.) (Friedrichs et al. 2022) It is true that Ord’s ‘The Precipice’ and MacAkskill’s ‘What We Owe the Future’ present the utilitarian argument in a way that might maximise an emotional response, both offering emotive portrayals of what is at stake for good or ill to overcome bias and neglect. However there is only so far this path can lead if emotive expressions of utilitarianism are bound by the same limitations described above. My first hope then, to begin concluding, would be to see Longtermism consider with its characteristic rigour how it might expand its scope for engaging a more ambitious and wholistic approach to communicating its goals and principles.

There is a broader set of moral resources available to overcome temporal parochialism and taking our place in the human story but this will require honestly asking some difficult questions. As Samuel Scheffler points out, there is, at the very least, an irony that a worldview that has sought to break bonds with past generations to maximise individual freedom from unchosen obligations has now recognised, for the sake of the future, the need to reforge links in the chain of human history and the duties towards others that those bonds enjoin. (Scheffler 2020, 7–8) Aspirations that each generation be unburdened by others undermine imagery of humanity being as one united individual which, at this moment in time, is like a young-person facing life-determining decisions and perils. (C.f. Ord 2020, 52; Greaves and MacAskill 2025, 17–18) The question I would hope to see Longtermists answer is whether the presently pervasive understanding of duties is capable of reconciling the individualism and radical autonomy that contemporary liberal accounts of the human person elevate with the obligations and self-sacrifice Longtermism requires? A strict methodological presumption that obligations only be accepted if they are demonstrated to be required (C.f. Unruh 2025, 144), may not be the best place to start to describe a relationship of generous charity with future generations, especially if most people experience relationships of sacrificial generosity on a different plane of reflection.

I recognise that my direction of travel will invoke accusations of fanaticism but, as someone who is committed to a rather different account of the human person, I can propose this widening of scope. As a person of faith, I am left wondering if moral rationalism can fully capture the possible greatness of the human condition when we are often at our best when we are behaving in an apparently irrational way: the mad scientific or artistic genius, the blinded lover, the radically generous saint. Might it be that our relationship with future generations best fits amidst these hard-to-rationalise aspects of human life, with something of fanaticism about them? Might it be that our relationship with future generations requires a heroic response of seemingly irrational generosity? I only signpost here some efforts I have made to explore how the Christian faith[i] can equip us to answer these questions (Wygnanski 2024), noting that Ord too has turned to saints and theologians to invoke radical generosity better to justify the costs Longtermism demands. (Ord 2014, 185) As someone with shared concerns for humanity’s future wellbeing, my hope with this essay is simply to make a case that all might benefit from a widening of Longtermism’s methods and a greater boldness in proclaiming that it is a part of the greatness of being human to be heroically, even slightly irrationally, generous in our relationship with others, including future generations, out of our love for humanity itself.

[i] I believe the varied landscape of Christianity and its relation to politics and culture in regrettably fundamentalist forms explains the correlation between religious affiliation and in-group favouritism observed by Schubert et al. 2025, 570, 573.
