More recently some line-drawers have focused on a mental criterion for personhood. Dr. Joseph Fletcher argues in his book Humanhood that "Humans without some minimum of intelligence or mental capacity are not persons, no matter how many of these organs are active, no matter how spontaneous their living processes are." This is not only an argument for abortion and infanticide; it's adequate justification for euthanasia and the potential elimination of those who do not possess a certain IQ. In other writings, Joseph Fletcher suggested that an "individual" was not truly a "person" unless he has an IQ of at least 40.
* In March 1989, six months after Becky Bell’s death, 16-year-old Erica Kae Richardson of Cheltenham, Maryland was assisted by her aunt in obtaining an abortion without her mother’s consent or knowledge. Erica’s aunt, a registered nurse, first took her to Washington Hospital Center, which would not perform the abortion because the pregnancy was 19 weeks along. She then took her to the Metropolitan Women’s Center in Laurel, where Dr. Gene Crawford carried out the abortion, puncturing her uterus in the process. Erica died several hours later from “rupture of [her] lower uterus and cervix with complications, including hemorrhage into the pelvic cavity surrounding the uterus and air embolism.”    
Human life never exists in a vacuum, we are inherently social beings in relationship with each other. Over fifty million babies have been aborted in America since 1973 — close to a sixth of the American population. There is inherent value and dignity in each of these individuals, and it is mind-boggling to think of all the potential contributions to society and culture that this lack represents. If society generally is of public concern (and clearly it is), then men should have some say on whether such massive numbers of those coming into it should simply be snuffed out, or allowed to participate.
