“We can't any longer have the conventional understanding of genetics which everybody peddles because it is increasingly obvious that epigenetics - actually things which influence the genome's function - are much more important than we realised.”
“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.”
“About 3 million IVF babies have been born since Louise Brown's birth in 1978. Bizarrely, when this life-giving treatment was first considered, it was massively controversial. A storm of vitriolic protest came from many religious leaders, journalists, politicians, regrettably even other scientists and doctors.”
“Animal rights activists talk about cruelty and torture, some backing their assertions by publishing out-of-date photographs of 'experiments' banned long ago. This is a misrepresentation. The work we do is performed with compassion, care, humanity and humility. I have never seen an animal suffer pain.”
“Childhood is not dead. Children were worse off when we were hunter-gatherers; they were threatened in medieval times and exploited during the Industrial Revolution. Was it any better in the time of Charles Kingsley or Charles Dickens?”
“I was born with my moustache and, no, I've never been tempted to shave it off. I don't spend a lot of time worrying about my face and, like Gilbert and Sullivan's Katisha, my best feature is my left shoulder-blade.”
“Much as I like and admire Richard Dawkins, I do think that to call a book 'The God Delusion' is very worrying because the title implies that if you don't believe in what I believe then you are 'deluded.' That, I think, is a dangerous concept and one that is unlikely to win hearts and minds.”
“We are more dependent on science and engineering than at any other time in history. However, there is plenty of evidence that far too many people are scientifically illiterate, often having been put off science at school.”
“Our aggression is a deep instinct which survives in all kinds of manifestations in modern man.”
“I don't believe the fertilised egg can be equated with the sort of human life that you and I represent, or our children represent.”
