A counter-example to Paul’s premise 2 is a human cancer cell, as Marquis points out.
When a human cancer cell appears in my body, it is a human individual according to the
criterion in premise 1: “a life is begun which is neither that of the father nor the mother;
it is rather new human life with its own growth.” But no one thinks an individual human
cancer cell is a human person. Indeed, almost any individual cell in a human body is a
counter-example. The only human cell that would not be an effective counter-example
here is a fertilized ovum, since Paul holds that such a cell is a person. We can predict he
would not hold that a red blood cell in my body is a person. A cancer cell is more
effective as a counter-example than any healthy human cell, because we actually desire to
destroy cancer, unlike healthy cells. Yet they would be protected, as it seems, according
to Paul’s principle.
