[W]hile Catholics can accept variations in life on earth as random in the sense of being unpredictable, no variations can be considered by Catholics as unguided and unplanned. Biologists and other scientists work hard to explain how life on earth originated and evolved. However, it is beyond the competency of science to tell us why, to paraphrase Heidegger, there are things rather than no things.This is brought on by Cardinal Schonborn's recent comments on evolution. It seems to me that there's more subtlety here than most scientists and proponents of so-called Intelligent Design grasp, and it's certainly outside journalism's scope to explain. Newspapers are limited to reporting many opinions, but this blog post helps separate the science from the theology. To me that indicates that while blogs won't replace news services, they can provide a forum for thoughts beyond journalism's purview.
