What he said about Earth Hour
Instead of going one hour without electricity, this campaign would be much better if it was one day or one week. Of course, going a week without electricity would teach people the exact opposite lesson than the one that the organizers of Earth Hour want: that electricity and energy are good things that are required for tranquility, freedom and happiness to exist in the first place, and without them we would have nothing but Hobbesian misery of war against all.
