However, I still recommend that you think through your responses in advance. Explain why on one explanation it is possible to take secular approach to ethics but not on the other. As Rachels admits, most actual cases of killing are morally worse than most actual cases of letting die. Rachels argues via the Bathtub Cases that the bare difference between killing and letting die doesn't always make a moral difference and that therefore the Doctrine of Killing and Letting Die is false. A fetus is an innocent human being.
Abortion is the killing of a fetus.
Therefore, abortion is prima facie wrong. Warren claims that infanticide and abortion have the same moral status, for infanticide is no more an act of murder than abortion is. However, she thinks that the two have a different legal status. Explain her position. Explain the difference between a necessary condition and a sufficient condition using examples.
