In history I decided to begin with Gibbon. Someone had told me that my father had read Gibbon with delight; that he knew whole pages of it by heart, and that it had greatly affected his style of speech and writing. So without more ado I set out upon the eight volumes of Dean Milman's edition of Gibbon's Decline and Fall of the Roman Empire . I was immediately dominated both by the story and the style. All through the long glistening middle hours of the Indian day, from when we quitted stables till the evening shadows proclaimed the hour of Polo, I devoured Gibbon. I rode triumphantly through it from end to end and enjoyed it all.

I believe that I had something called epigenetic imprinting, which I actually read about in a book called The Female Brain by Louann Brizendine. Not to self-promote too much, but I loved it so much I wrote a movie with a brilliant comedian named Neil Brennan and made the move this year. That’s how profoundly it changed my life, because I believe that the more we know about our neural brain wiring, the more freedom we have and the more patience we have with ourselves.

It was probably a series of biographies of scientists like Pasteur, or even earlier ones — Leeuwenhoek inventing the microscope and Madame Curie. I forget how many others, but it was really just, for me, a fascination to learn about these great heroes. At that time, of course, they were totally inaccessible, almost non-human, to me. It became very interesting to me.

C. S. Lewis - his works were very, very important during my time there. We had discussion groups. I did become more attracted to it although I still attended the Methodist church. If you read Lewis. Then until this day, he did the lectures, something like christian behaviour and 'the screwtape letters', and we were all discussing them. I thought some of his work was the most illuminating to people reaching out to christianity because you're always questioning particularly at that age and you're looking for reassurance and for answers. Indeed you go on questioning throughout your life.

They encouraged me, the way I do others now, that if you really have something that you like to do, that’s what you probably should do. Despite what everybody says, that you can’t make a living, or that’s not practical, or a thousand reasons why you may not do this or this or this. If that’s what your heart says you should do, chances are that you ought to listen.

To the extent that we ignore this, forget about it, become complacent, or believe that it is so infinite that it can take care of itself, we are in trouble.
