Philosopher Gary Gutting, who always writes something interesting for The Stone column in The New York Times, recently asked if Pope Francis might reconsider the Catholic Church's traditional absolutist opposition to abortion.
In doing so, Gutting makes a case for a kind of minimalist justification for abortion-- that is, abortion is immoral in most circumstances but there are a few cases where abortion is justified (in the case of rape, for example).
For that reason, the column makes for informative reading. Still, Gutting puts the cart before the horse: how and why would Pope Francis review the Church's view on abortion before reexamining its even-more-restrictive view of artificial contraception?
Anything can happen, of course, but Pope Francis has not really indicated a willingness to reconsider the doctrine of the Church on sex, conception, and abortion. Everything I have read from and about Francis is that he is advocating for a change of tone and emphasis, not what is moral or immoral.
