Dr. Steve Sverdlik, philosophy professor at SMU, will be giving a talk at the Dallas Philosophers Forum titled "Ensoulment and the Morality of Abortion: A History and a Critique."
The lecture starts at 7:30; the DPF website encourages attendees to arrive early to be seated and order dinner by 7:15. Cost for the lecture is $5.
From the DPF website (http://www.philosophersforum.org/schedule_current.html):
"Catholics and some other Christians often defend the position that abortion is morally wrong by claiming that ensoulment occurs at conception, so that abortion kills a being with a soul. I give a short history of Christian thinking about ensoulment. Contrary to popular opinion, over most of their history Christians did not believe that ensoulment occurs at conception. So their moral objection to early abortion rested on another claim. It was only about 1620 that Catholics started to assert that ensoulment occurs close to the time of conception. I go on to criticize Christian thinking about ensoulment from a secular point of view."
