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 coordinates that split the schools
The stances
Extinct species are as real as we are; they have standing.
60 schoolsOn 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.

- 1% The past is as real as the present; regret is a real attitude toward a real thing. on Is regret rational?
- 1% Yes — matter was created and is conserved as a real substance. on Is the world created from nothing?
- 1% Yes — the physical world is fully real, mind-independent, persisting. on Is the physical world fully real?
- 1% Matter is morally considerable insofar as it is created or conserved good. on Does matter have intrinsic moral standing?
Past beings are part of the cycle; we owe them what we owe ancestors.
26 schoolsOn 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.
Where this stance leads ⓘ
- 1% Past, present, and future are bound in cycles — duties span generations as a matter of course. on How much weight do future people deserve?
- 1% The past is part of a cycle one keeps returning to; regret is one of the gates of the cycle. on Is regret rational?
- 1% Loss is part of cycles; what disappears returns in another form. on Is environmental damage ever truly permanent?
- 1% Civilization rises and falls in cycles; recovery is structural to history. on Can a civilization recover from collapse?
- 1% Local entropy increase is part of a cycle; the moral category is participation in the cycle. on Does the second law of thermodynamics mean something morally?
Extinction is path-dependent; the species exists in branches we didn't take.
5 schoolsOn 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.
Where this stance leads ⓘ
- 1% The future branches — what we owe depends on which branch we create. on How much weight do future people deserve?
- 1% Other branches exist; regret tracks roads not taken that are nonetheless real. on Is regret rational?

- 1% Coincidence is exactly what the math says it is. The pattern is in the noticer. on Are coincidences ever more than coincidence?
- 1% What is irreversible in this branch is reversible in another. on Is environmental damage ever truly permanent?
Past species no longer exist; what we owe is to the present and the future.
39 schoolsOn 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.
Where this stance leads ⓘ
- 1% Time arises from events or from a deeper substrate — the future is not yet. on How much weight do future people deserve?

From the One's vantage, species and extinction are themselves conventional.
3 schoolsOn 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.
Schools the coordinates don't place
These schools don't satisfy any stance's coordinate pattern strongly enough to be assigned — either because they decline to commit on the question (Confucianism is famously silent on what comes after; Pyrrhonian and pragmatist traditions suspend judgment), or because their attribute signature crosses categories in a way the five buckets don't capture.
