The first good to come of it will be that someone will murder Singer.
The cute thing about secular fundamentalists like Singer is that they are always bleating about "Science" and then failing to defend their beliefs scientifically. Does he have data showing a marked decrease in the number of people who value life? Is the pro-life movement losing steam and influence?
For that matter, what objective basis does the NYT have for declaring Singer a great philosopher, as opposed, to, say, a driveling fool? Compared to the great philosophers of history, is anyone going to remember this guy in a hundred years? (If so, I predict it will be the same way they remember Neitzsche - as a precursor to Hitler.)
