I think that people don't know how to do anything anymore. My father was a janitor. He could take a car apart and put it back together. He could build a house in the back yard. Today if you ask people what they know they say 'I know how to hire someone.'
Science is properly more scrupulous than dogma. Dogma gives a charter to mistake but the very breath of science is a contest with mistake and must keep the conscience alive.
