I do not think commodities are taken for granted. One of the convergences in time I noticed, and to me seemed very important, was the emergence of paper money. There had been permissionary notes, exchanging money by writing it, but there was no duplicated form of guaranteeing an exchange.

Our traditional stories are based on an aristocratic model without a middle class, whereas The Arabian Nights reflect people living in cities, traders, merchants, travelers, with a wide range of personalities.

I do think that this represents a kind of shift towards myth, a recovery of myth, largely through the popularity of writers like Philip Pullman. Somehow myths have returned as a serious subject. It used to be scorned...really scorned. It was part of a nursery tradition, and it was also rather tainted - but not in an immovable way - by the association with right-wing ideologies after the World Wars.

I am not a great believer in dialectical struggle. I am much more of a fusion person. I see it as a dialogue, or trialogue, or polylogue: many, many, many voices, going back a long way. The cultural picture is much more mutually enriching at many different levels, manufacturers...absolutely, design and calligraphy. It's an amazing amount of cross-interests between people.

The tales are quite hard to remember and I found that going back to it between bouts of writing fiction, I was having to retrace my steps quite a lot, because the stories are very intricate and the material is elusive, and possibly with age, my memory is not as malleable as it used to be.

There is humanist enterprise of the book, and amongst that there are many, many stories. And that is why at the end, when he says that the stories are so illuminating that they must be engraved and encased in gold and put in the palace library, the people who compile the book are telling us that this is a collection of human wisdom.

Wonder has no opposite; it springs up already doubled in itself, compounded of dread and desire at once, attraction and recoil, producing a thrill, the shudder of pleasure and of fear.
