The blob-person and person-blob transitions give ethicists, legislators, and judges a great deal of trouble. How does the law keep up as the initial blob advances to human being, and then the human being degrades to blobness?

In an earlier era, perhaps, things were simpler—you were either alive or dead, though the status of the fetus has always given people trouble. Today, science has broken down the blob phases into minute intervals: conception, the development of the embryo, its attachment to the uterine wall, the emergence of electrical activity in the fetus’s brain, viability, birth; and then, on the other end, the gradual petering out of brain activity. The distinctions matter. Killing a human being is murder; discarding unwanted cell tissue is not.

Familiar culture-war controversies have erupted over these issues. The law embodies uneasy truces and compromises, and, as is always the case, contains ambiguities and inconsistencies; and state laws vary a great deal. But a rough logic has e
