Dilemma
When does a person begin?
The political question of abortion sits atop an older ontological one: at what point does there exist a someone — a being with moral standing — rather than merely the materials from which one will form?
Context
Behind almost every modern controversy about abortion is a metaphysical disagreement that long predates them. Both sides typically agree on the biology: at conception, a new genetic individual exists; at six weeks, a heartbeat; at thirteen weeks, response to touch; at twenty-three weeks, viability outside the womb; at birth, a being everyone agrees is a person. The disagreement is about which — if any — of these biological milestones coincides with the appearance of a someone: a being whose interests, dignity, and (on most ethical views) right not to be killed deserve moral weight. That question cannot be settled by biology because it is not, in the end, a biological question.
Why it matters
A school's view on this underwrites its view of when abortion is and isn't permissible, but it also shapes its view of stem-cell research, end-of-life care for the persistently unconscious, the moral status of cryopreserved embryos, and any case where biology produces a being whose personhood is unclear. The political position is downstream of what mind and personhood are, not the other way around — which is why interlocutors who disagree on the political question almost always disagree, at the prior level, on what a person is.
The coordinates that split the schools
The stances
A person exists from conception — when a new being comes into existence.
75 schoolsOn this view, personhood is conferred by the existence of an individual member of the human kind. The moment a unique genetic identity comes into being, a someone exists — and from that moment every developmental milestone is merely a stage in the unfolding of an already-existing person, not the appearance of one.

A person comes into being gradually, as the capacities of a mind develop.
18 schoolsOn this view, personhood is not a status conferred at a moment but a property of beings with certain capacities — to feel, to suffer, to prefer, eventually to reflect. A zygote has none of these; a late-term fetus has many; a newborn has most. Moral standing scales with capacity. The early embryo has the genetic potential of a person but is not yet a person in the morally relevant sense.

Personhood is conferred by being-in-relation.
11 schoolsOn relational views, person was never the name of a thing that exists on its own — it is the name of a node in a web of recognition, obligation, kinship, and ecology. The question of when a being becomes a person is the question of when it is woven into that web.

The question presupposes a fact of the matter that isn’t there.
15 schoolsThere is no point at which an unchanging core "comes into being"; there is a stream of conditioned arising that we choose to mark, or not mark, at various places. The political and moral question of how to treat developing humans is real; the metaphysical question of when a someone really exists is a category error.

From the standpoint of the One, the question doesn’t apply in the form it is asked.
13 schoolsOn non-dual views, the apparent plurality of selves is itself a perspectival distinction within a deeper unity. The question of when one self begins within that One is conventional, not ultimate. What follows ethically is then a question for the conventional level — which is exactly where the political question already 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.
