What I like about sceptics is that in good science you need critics that make you think: 'Crumbs have I made a mistake here?' If you don't have that continuously you really are up the creek. The good sceptics have done a good service but some of the mad ones I think have not done anyone any favours.
If Germany thanks to Hitler and his successors were to enslave the European nations and destroy most of the treasures of their past future historians would certainly pronounce that she had civilized Europe.
