Not fact-finding, but attainment to philosophy is the aim of science. – Martin H. Fischer (1879–1962)
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 dont 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. – James Lovelock
