"September 11, 2001, serves as a reminder of what happens when you try to organize a world on the assumption that religion and spirituality are merely private matters, and that what really matters is economics and politics instead. It wasn't just concrete floors, it was massive towers, that were smashed to pieces that day, by people driven by "religious" beliefs so powerful that the believers were ready to die for them. What should we say? That this merely shows how dangerous "religion" and "spirituality" really are? Or that we should have taken them into account all along?"
