Dilemma

Do we owe extinct species something we cannot give them?

A species that no longer exists cannot be helped, cannot be consulted, cannot benefit. Whether anything is owed to it anyway turns on what kind of reality past beings have.

Context

Biologists estimate that 99% of species that have ever lived are extinct, and the Anthropocene-era rate of extinction is orders of magnitude above background. Memorialisation projects, ex-situ conservation, de-extinction research (mammoths, thylacines, passenger pigeons), and the broader question of what we owe to the past have all gained intellectual seriousness. The disagreement turns on a metaphysical question: what kind of reality does a no-longer-existing being have, and what (if anything) can be owed to it?

Why it matters

How a tradition answers determines whether extinct-species memorialisation is meaningful, whether de-extinction is obligatory or supererogatory or hubristic, and whether the moral weight of present extinctions includes a duty to past (now-extinct) members of the species or only to the living. The framework speaks to this because what the past is bears on what its inhabitants are owed.

The stances

Extinct species are as real as we are; they have standing.

97 schools

On this view, the dodo and the great auk are not merely past; they are out there, on a different stretch of the time axis. Whatever standing a living species has, an extinct one has too — just located elsewhere in time. Memorialisation is real moral work, not consolation; debts incurred in driving a species extinct are not cancelled by the species' non-existence-now.

Why these schools land hereSchools with the eternalist signature (Substantival + Linear) treat all moments as equally real. Catholic, Reformed, EO, Lutheran, LDS, Islamic, Jewish, and Zoroastrian traditions further hold creation as covenantally significant — the dodo is part of creation's roster regardless of whether it has instances now. Secular eternalists (Realism, Determinism, Multiverse, OOO, Analytic Metaphysics, Critical Realism) share the formal commitment to the reality of past beings; whether they extend moral standing depends on other commitments.

Past beings are part of the cycle; we owe them what we owe ancestors.

38 schools

On cyclical views, the relationship to past beings — ancestors, lineages, predecessors — is structurally present, because past and future are part of the same ongoing structure of return. Extinct species are not categorically different from extinct human ancestors or non-yet-born descendants: all are part of the web the present sits in.

Why these schools land hereCyclical schools — Buddhism, Taoism, Stoicism, Hindu cyclical traditions (Advaita, Dvaita, Sāṃkhya), Sufism, Sikhism, Jainism (especially with its non-harm doctrine extending to all life), Yogācāra, Hermeticism, plus the relational indigenous schools (Animism, ATR, Ubuntu, Afrofuturism, Deep Ecology, Shintoism) — generally treat extinct species as real participants in the cycle that present action either honors or fails to honor. Seven-generation thinking extends in both temporal directions.

Extinction is path-dependent; the species exists in branches we didn't take.

5 schools

On branching views, an extinct species exists in branches where its decisive moments went differently. Whether we owe the species something depends on whether we identify with this branch alone, with all branches, or with the multiverse as a whole. De-extinction research, on this view, is the engineering project of bringing branch-existing beings back into this one.

Why these schools land hereBranching schools — Multiverse Theory, Simulation Theory, Quantum Realism, Dataism, Gamer, Psychedelic, Afrofuturism, Transhumanism — read past contingencies as branch points where the unchosen possibilities remain real. The moral question becomes one of cross-branch obligation, which the science does not settle on its own but which is a coherent question given the metaphysics.

Past species no longer exist; what we owe is to the present and the future.

64 schools

On these views, the dodo isn't somewhere; it isn't. The moral weight of extinction is fully captured by what we owe to the living (including future biodiversity, including the ecological systems the species was part of) — not by debts to beings who no longer have interests.

Why these schools land hereSchools with time relational or emergent + linear traversability — Presentism, Process Philosophy, Phenomenology, Pragmatism, Pragmatic Realism, Existentialism, Constructivism, KTI, plus a range of process- and event-oriented schools — deny that non-existing beings have interests that can be owed. Stewardship of extant species is real and weighty; the same obligation does not naturally extend backwards to the non-existent.

From the One's vantage, species and extinction are themselves conventional.

4 schools

On non-dual views, the species we mourn — and the act of mourning — operate at the conventional level. Compassion for the extinct, like compassion for the living, remains; the metaphysical question of what we 'owe' the extinct presupposes a framework of distinct beings and finite history that the view relativises. Stewardship and grief are not denied; their final ontological interpretation is.

Why these schools land hereAdvaita Vedānta (and any other Singular school whose other coordinates don't place it elsewhere). Practically the cluster supports memorial practice and stewardship of what remains, without elevating the categories of species, extinction, or intergenerational debt to ontological ultimacy.
