Of course it is a very simple matter to identify genes which might modify intelligence or memory and start thinking about whether you want to enhance a human, and the next generation is going to have to deal with that issue. Should we be trying to enhance humans rather than trying to educate them and so on?

When I look in the mirror, I am slightly reminded of self-portraits by Durer and by Rembrandt, because they both show a degree of introspection. I see some element of disappointment; I see a sense of humour, but also something that is faintly ridiculous; and I see somebody who is frightened of being found out and thought lightweight.

We must not fail to recognise that television can be a hugely positive influence in children's lives, one of the greatest educators in contemporary society and an increasing influence on all the children followed in 'Child of Our Time.'

Having a child is arguably the most important thing you do in life.
