Extract
Some people, however, would argue that an early human being does not become a “person” till sometime after birth, and others would argue that this time has arrived when fetal brain waves are recordable (about 6 weeks). Obviously, any point along the way, including the 23-week mark, is arbitrary and depends on each person’s perspective. . . surely it is not just or scientific to choose some arbitrary time.
