What this is

A syllabus of readings relating to ‘longtermist’ philosophy. I’m posting it here because I hope it might inform syllabi for university courses, reading groups or EA fellowships, and because I would love to see people share suggestions for other works to include. 

As this list was designed to include roughly a semester’s worth of material it is, needless to say, not an exhaustive resource. Indeed, each of the dozen topics could have a syllabus of their own and I am not myself very familiar with the relevant literature – suggestions are very welcome!

Some background 

Like many other student groups, my previous university EA community would often invite faculty speakers to join dinner discussions and fellowship meetings. In our group, the ethics professor Shelly Kagan has been generous enough to regularly attend group discussions. While he initially joined for conversations on Peter Singer’s arguments on charity, we started a few years ago to instead focus on questions regarding intergenerational ethics.

After a few very successful group discussions, I suggested that Kagan could teach a course on the topic and, a few years later, that course is now being taught as an undergraduate seminar.

While Kagan was preparing the course, I offered to make a draft syllabus for it, and although I believe Kagan’s actual syllabus looks quite different from the list I produced, I figured that it might nevertheless be worthwhile to share here on the forum. I should stress that this syllabus is independent of the course and professor and that any errors thus are entirely my own. 

Why I think this might be valuable

I think we got quite lucky to find a university professor who was sufficiently interested in – and sympathetic to – longtermism that they would teach a course on it, and I’m not sure that this is something that could happen at every school with an EA group. But conditional on finding such a professor, I hope this syllabus could increase the likelihood of them teaching a course like this, which seems really valuable. Of course, I also hope that this could prove useful for reading groups, fellowships, and the like!

Crucially, I do not see this as a resource for “convincing people that longtermism is true.” (Edit: For some compelling arguments as to why our community should be careful about seeking 'value-alignment', see this great post by CarlaZoeC.) Rather, I hope that the readings can inspire and inform robust conversations about the strengths and weaknesses of longtermism – a philosophy that, in the scheme of things, remains very new and unexplored. Indeed, several of the readings included here pose serious challenges to various aspects of longtermism that are worth carefully considering.

Some considerations that went into making this syllabus

Intergenerational ethics ≠ longtermism

The course this syllabus was made for is called “Ethics and the Future,” which underscores the fact that, as I see it, ‘intergenerational ethics’ (a philosophical topic or field) is not equivalent to  ‘longtermism’ (a philosophical position and research agenda within that field). So while longtermism is heavily featured, it’s not the only thing you’ll find on the syllabus.

Formalism and accessibility

In addition to the usual dose of jargon, many of the papers on this subject – especially on the topics of discounting and population ethics – include a lot of mathematical expressions that may pose a barrier to some readers. I tried to keep accessibility in mind when making the syllabus and excluded a few potential readings on those grounds, but I still suspect that some of the readings might be challenging to many students without a lot of formal training (myself included). Ultimately, however, this is just a draft, and it can obviously be adapted to improve accessibility depending on the purpose and audience. 

A note on diversity

Much of the field of academic philosophy suffers from very noticeable demographic homogeneity, and the subfields discussed here are no exception. As a regrettable consequence, almost all of the readings on this list are by white authors and a majority of them are written by men. While the causes and consequences of this trend deserve a much longer, separate discussion, I will nevertheless briefly address it here. 

On this topic, I often hear the argument that we should “evaluate ideas based on their merits rather than the identity of the author.” In principle, I am definitely sympathetic to this view. In practice, however, I believe that (moral) philosophies – and any blindspots or weaknesses they may have – can be influenced by their social and historical context, as well as the positionality of those who developed them. 

This is definitely not to say that we should discard (or elevate, for that matter) any particular philosophy or piece of work simply due to the identity or culture of the originator. However, if we think of EA's entire “portfolio" of philosophical traditions and demographic groups from which we learn, I think there is a serious risk of blindspots and errors if the origins of the source material are very homogenous.

Take, for instance, the moral notion that we must afford equal rights to people of different genders: while John Stuart Mill – an early feminist of sorts – is an example that moral insights may dawn on anyone (i.e., a man pushing for women’s rights), I think it is extremely plausible to suggest that these important insights would have gained more of a foothold much sooner if women had had more of a voice and platform in academic and political circles. (Note: I’m no expert on this particular history and would be curious to hear from others who know more.)

More generally, the fact that there are wide differences in views across cultures, genders, ethnicities, races, and socioeconomic groups suggests that people, as a matter of fact, are not reasoning completely independently of their positionality, despite that being an admirable ideal for us to aspire to. Consequently, it seems to me that representing a wide range of peoples is a clear way to reduce the risk of blindspots and errors, and thereby maximise the chance of identifying “correct” moral views.

Additionally, I think that there are compelling community-oriented reasons for valuing diversity on syllabi and reading lists, as some people might be more excited about engaging with a community that seems informed by a wider range of perspectives.

All of this is to say that I think authorship diversity is a desirable feature of a reading list (among many others, of course). So, insofar as this particular syllabus does very poorly on that front, I’d really appreciate suggestions for works to include, and I’d generally be excited to see other efforts to address this issue more broadly.


This syllabus was heavily inspired by the reading list from Will MacAskill and Christian Tarsney’s graduate seminar on Topics in Global Priorities that I had the pleasure of auditing in the spring of 2019. The effort to expand and revise the syllabus would not have been possible without the generous help from Andreas Mogensen, Brian Tse, Christian Tarsney, Emma Curran, Eui Young Kim, Frankie Andersen-Wood, John Mori, Magnus Vinding, Mojmír Stehlík, Sebastian Sudergaard Schmidt, Shelly Kagan, Charlotte Unruh, Tatjana Visak, Teruji Thomas, and Xuan (Tan Zhi Xuan). Again, any errors are my own.

The syllabus

Core reading

Optional reading

Week 14: Longtermist cause prioritisation part I: Avoiding suffering, reforming institutions.

Goal: To move from the “why” towards the “what” and discuss potential priorities for longtermists.

Core reading

Optional reading

Week 15: Longtermist cause prioritisation part II: Utopia and its discontents

Goal: To end on a high note by reflecting on what the future could look like, but also to consider a pointed critique of longtermism and utopian thinking.

Core reading

Optional reading

**Note: In my view, the tone of this essay is at times antagonistic and some arguments seem uncharitable towards the positions they seek to critique. I include the essay here because I believe it raises important concerns about risks associated with longtermism that warrant good-faith discussion; however, this should not be read as an endorsement of the more polemic features of the essay. 


I hope some of you will find this resource in any way useful. As noted above, I look very much forward to hearing any suggestions and comments you might have!

Sorted by Click to highlight new comments since:

To make this list easier to navigate, I've compiled it into a spreadsheet, and organised as many as the PDFs as I can into one place:

I'm not totally sure about whether it's ok to re-upload a bunch of published academic writing like this — would be interested in people's thoughts. For what it's worth, I haven't uploaded anything that was behind a paywall or not publicly available.

Anyway, hope some people find this useful!


Thanks for this very interesting syllabus and thank you for mentioning the issue of diversity and for the first steps of tackling it. I don't see this issue discussed very often on the EA forum and in EA adjacent academia.

Thanks for your comment. I wholeheartedly agree that this is generally a neglected issue in the community, which is partly why included the brief note – although, as stated, I believe it deserves separate and longer discussions.

Good to see! I've added this to the list of EA syllabi and teaching materials. Let me know if you want to be credited as something other than jtm.

Thanks! You can just use my full name (this is Joshua from the Yale group).

Very minor note, and I doubt that this much matters to Julia, but for future cases where this pops up, I think it's better if you just typed your preferred name for computational kindness reasons, since presumably your full name is more readily accessible to you than to Julia.

I have compiled a list of courses on longtermism and related topics, which includes both this one and the one taught by Prof. Shelly Kagan, as well as a number of other courses.

Thanks, Pablo!

This is fantastic, thank you so much for putting it together.

Thanks so much for making this — awesome work! It's worth noting how little in the way of published academic writing addresses longtermism specifically, and by name. Hopefully that'll change over the next couple of years.

Thanks, much appreciated! I should perhaps have indicated which of the pieces on this list have been published with peer review. Generally, most of the articles have, with the exception of the book chapters, GPI working papers, and a few other working papers.

Great list, thanks!

I link to it in my newly posted syllabus on existential risks:

Terrific, thanks!
