Dilemma
Should we edit the human germline?
Whether human nature is a given biological kind, a constructed category, a relational achievement, a family-resemblance cluster, or a conventional distinction within deeper unity is the ontological question the policy debate over heritable gene editing is mostly about.
Context
CRISPR-Cas9 and related technologies have made editing the human germline — changes that pass to descendants — an engineering possibility rather than a hypothetical. The first heritable edits in humans have already been reported, prompting moratoria, criminal charges, and a policy debate that is louder than it is clear. Underneath the regulatory question is an ontological one: what kind of thing is human nature? Schools across the atlas split on this question along the same lines they split on every other 'what is X really?' question — and the political conclusion (permit, restrict, prohibit) does not fall directly out of the ontological position.
Why it matters
How a tradition reads human nature shapes whether it treats heritable editing as transgression of something given, as a practice-revision to be evaluated on its consequences, as a reshaping of the relational fabric of descent and kinship, as an empirical question without metaphysical stakes, or as ordinary moral reasoning at the conventional level. Schools sharing a stance here can land on quite different practical recommendations, and schools differing on the underlying ontology can converge on shared positions about what should be permitted.
The coordinates that split the schools
The stances
Human nature is a real biological kind given by reproductive biology or by creation; editing the germline transgresses what is given.
114 schoolsOn this view, the human form is a real feature of the world — handed over by reproductive biology, by divine creation, or by both. Germline editing rewrites what was given, not just what was lying around to be improved. The objection is not that specific edits are reckless (though they often are) but that the practice treats human nature as raw material when it is, in fact, a kind.

The categories we count as 'human' are emergent from practice; germline editing is a practice-revision like any other.
33 schoolsOn this view, biological facts about the genome exist, but what we count as 'human nature' is downstream of practice. The germline is one more thing humans now have technical access to; the question is not whether the practice transgresses an essence but whether the revisions it produces are good ones. The norm against germline editing, where it has held, is itself a social construction that can be revised.

Personhood is constituted by relations of descent and kinship; germline editing reshapes the relational fabric.
30 schoolsOn relational views, what makes someone a person is the web of kinship, ancestry, and community they sit in — not a property the body carries alone. Heritable editing intervenes in exactly this fabric: the lineage that ancestors handed on, the descent that descendants will receive. The objection (or assent) is not about transgressing an essence but about reshaping the relations that constitute persons.

'Human nature' is a cluster term without a single essence; the editing question is empirical, not metaphysical.
16 schoolsOn this view, 'human nature' picks out an overlapping cluster of features — anatomical, developmental, cognitive, social — without a single essence the cluster reduces to. The question of whether germline editing is permissible doesn't turn on transgressing an essence (there isn't one) but on the empirical and ethical question of what particular edits do to particular lives.

The distinction between edited and unedited is conventional within a deeper non-dual reality.
15 schoolsOn non-dual views, the contrast between an 'edited' and an 'unedited' human — like every binary distinction between apparent selves — is a perspectival distinction within a deeper unity. The practical questions of safety, consent, and justice operate at the conventional level where most of life is lived; at the ultimate level the modification is one more pattern in the play of forms.
