I've often reflected on this in the past weeks as I've been following the presidential campaign: Very often, I thought it would have been great for both of these guys to sit down and be force-fed a couple of dozen episodes of Star Trek.

I do what I do in my mother's name because I couldn't help her then. Now I can.

So far as education is concerned, it has had a significant impact on a lot of young people who turn to science as a much more exciting and interesting study than they otherwise might have found, entirely as a result of becoming involved with Star Trek.

What identifies an individual as a king is how other people behave towards him. All authority is assumed, and if other people don't accept your authority then you don't have it. Perhaps the critical thing to being a convincing figure of authority is actually not to try too hard.

I've been in politics all my life. In 1945, I committed my first act of civil disobedience during the election campaign for the first post-World War II general election, when the Labour Party, to everyone's amazement, ousted the Conservatives.
