By Michael Warren Davis, Crisis Magazine - I’m ambivalent about that most common pro-life argument: that, because life begins at conception, to abort a pregnancy is to commit murder. That’s not to say I don’t believe it’s true. On the contrary: it’s not only true, it’s obviously true. It’s one of the few points upon which credible scientists and ethicists can agree. What gives me pause about this argument is what inevitably follows from it.
