Not too fast on this Pope. John Paul II did send an encouraging sign to a seminar back in 1996. The present Pope Ratzinger is in full regression on evolution and not only.
To set the tone of recent views on Darwin, the Pope has rested the matter in the competent hands of Cardinal Schonborn of Vienna, whose 2005 NYT article caused a major stir.
It is comforting to see that this Pope is very much concerned with the defence of reason against the ideologies of relativism, evolutionism and reductionism. That's True Reason, of course.
