Dilemma

How much weight do future people deserve?

If a billion people will exist in the 25th century, do their interests count for as much as the interests of a billion people alive now? The answer turns on what kind of reality the future has.

Context

Effective altruism's longtermist wing argues that future people are morally just as significant as present people; what matters most about the next century is its consequences for the next million. Critics on the left worry the framing licenses neglect of present suffering; critics on the right worry it licenses unaccountable speculation about the very distant. Climate ethics runs the same argument from a different starting point: every choice we make is also a choice about the world we leave to people who don't yet exist to speak. Indigenous ethics has long taught seven-generation thinking. AI existential-risk discourse is longtermism applied. The dispute looks like a debate about moral weight, but it sits atop an older question about whether future people are real, what kind of reality they have, and whether their reality is independent of, or constituted by, what we do now.

Why it matters

The framework's time attributes — time_ont_status (is time a real container, a network of relations among events, or something that arises from a non-temporal substrate?) and time_traversability (does time run once linearly, cycle, or branch?) — directly determine what kind of standing future people have. The schools partition along these axes, and the partition does not align with the realist/constructionist axis of the personhood and marriage dilemmas: philosophical realists and Buddhist process philosophers, who disagree on almost everything, can agree about cyclical time and thereby agree on intergenerational obligation.

Future people are as real as you are — and their interests count for as much.

On this view, time is a real container in which all moments equally exist. The future is not waiting to come into being; it is out there, and the people in it are real in the same sense you are. To discount their interests because they happen to be located further along the time axis would be like discounting the interests of someone located further along a spatial axis — morally arbitrary.

Why these schools land hereSchools in this cluster hold time to be substantival (a real feature of reality, not just a network of relations among events) and traversed linearly (one direction, irreversibly, with all moments equally real along the way). This is the block-universe view associated with Eternalism and General Relativity's spacetime, but it appears across a wider range of schools that share the formal commitment: every moment, including every future moment, is already part of what is. The moral conclusion is closest to time-neutral utilitarianism: a person tomorrow, in a century, in a million years has the same ontological standing as a person now.

Where this stance leads ⓘ

Past, present, and future are bound in cycles — duties span generations as a matter of course.

38 schools

On these views, time is not a one-way arrow but a structure of return: cosmic cycles, karmic cycles, the seasons, the succession of generations. To act now is always also to act for the ancestors who shaped your inheritance and for the descendants who will inherit yours. Intergenerational obligation isn't an inference from a moral theory — it's the default structure of being in time at all.

Why these schools land hereThese schools share time_traversability=Cyclical: time is read as a structure of recurrence rather than as a single linear trajectory. The cluster brings together schools that disagree on almost everything else — Buddhism, Taoism, Stoicism (cosmic cycles), Sufism, Hinduism's cyclical cosmology — and shows that they share a structural commitment about time that underwrites a remarkably consistent ethics of seven-generation thinking. Action in the present is, on this signature, automatically action on the past and the future, because past and future are also present in the cycle.

The future branches — what we owe depends on which branch we create.

5 schools

On these views, time is not a single line stretching forward but a tree of possibilities, at each moment opening into alternatives. Future people are real in some sense, but which future people exist depends on which branches get actualized — and that is the work of present choice.

Why these schools land hereThese schools share time_traversability=Branching: time is structurally many-valued, with the future containing multiple real possibilities rather than a single determined path. Multiverse Theory and the many-worlds interpretation of quantum mechanics are the obvious cases, but Simulation Theory and various branching cosmologies share the commitment. The ethical conclusion is distinctive: the interests of future people are real in proportion to the likelihood of the branch in which they exist, and present action is partly a question of which futures one is willing to bring into being.

Where this stance leads ⓘ

Time arises from events or from a deeper substrate — the future is not yet.

64 schools

On these views, time is not a fundamental container that already holds the future. It is either constituted by the ongoing pattern of events (relational time) or emerges from a non-temporal substrate — mind, becoming, lived experience (emergent time). Either way, the future is what present causes are unfolding into, not a place where people already are. Stewardship is still real, but the moral weight of acting now in light of future people lives on different footing from acting in light of those who already exist.

Why these schools land hereThis is a broad cluster that combines two distinct philosophical commitments under one structural conclusion. The first sub-cluster (Relational time + Linear) takes events to be fundamental and time to be the relations among them — Nihilism, Pyrrhonism, Hylomorphism, Object-Oriented Ontology, Epicureanism, and Islamic Philosophy / Falsafa (notably Avicenna and al-Ghazālī on the relational nature of time). The second sub-cluster (Emergent time + Linear) takes time itself to arise from a more fundamental substrate — mind, becoming, intersubjective constitution — and so includes Idealism, Phenomenology, Existentialism, Pragmatism, Process Philosophy, Kantian Transcendental Idealism, Presentism (which the atlas reads as time emerging from the moment of presence), Postmodernism, and many others. The schools differ enormously on what time emerges from, but agree on the formal point: the future doesn't sit ready-made beyond a current moment; it has to be made.

From the One's vantage, generations are themselves conventional.

4 schools

On non-dual views, the distinction between present and future people is itself perspectival within a single underlying reality. Obligation across generations remains real at the conventional level where moral life happens; the metaphysical claim that future people 'exist' or 'don't yet exist' as a final ontological fact is what the view relativises. Stewardship is supported; the framing in which 'how much weight do future people get?' is a decidable ontological question shifts.

Why these schools land hereAdvaita Vedānta (and any other Singular school whose other coordinates don't already place it elsewhere). Schools like Idealism and Sufism Wahdat al-Wujud also share Singular but land in stances they have stronger coordinate matches for (not-yet, eternally-real); the non-dual stance here catches the residual.
