Author of book A Defense of Abortion describes his son's ultrasound picture

"In the top drawer of my desk, I keep another picture of Eli. This picture was taken... 24 weeks before he was born. The sonogram image is murky, but it reveals clearly enough a small head tilted back slightly, and an arm raised up and bent, with the hand pointing back toward the face and the thumb extended out toward the mouth. There is no doubt in my mind that this picture, too, shows the same little boy at a very early stage in his physical development. And there is no question that the position I defend in this book entails that it would have been morally permissible to end his life at this point."

-David Boonin, A Defense of Abortion, quoted from A Case For Life by Scott Klusendorf p. 14.
