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.

When I find myself in the company of scientists I feel like a shabby curate who has strayed by mistake into a room full of dukes.

What makes me sad about school is that the people who are unhappy are unhappy because they don't believe it will change. And I just want to say: 'It does! High school ends and it's over.' I will tell anyone that it's OK to be unhappy at school make lots of mistakes and then it will be over.

I once made the mistake of going for a whole row of false eyelashes which was just wrong as it gave me a sad puppy-eyed look.

I respect and empathize with reporters and editors who must compete in today's environment. And I know full well that when I've been covering campaigns which I still do I've made my mistakes and have been far from perfect.

I never make the mistake of arguing with people for whose opinions I have no respect.

There is a holy mistaken zeal in politics as well as in religion. By persuading others we convince ourselves.

I am not going to condemn anybody. That's where religion gets a bad name when people get holier than thou. We are all human. If my children make a mistake I want them to know it is all right and they should try harder next time.

Formerly when religion was strong and science weak men mistook magic for medicine now when science is strong and religion weak men mistake medicine for magic.

The biggest mistake is believing there is one right way to listen to talk to have a conversation - or a relationship.
