Good photographs aren't just complex. They are enigmatic. Images are beguiling. And the way they play into our psychology, into our visual cortex, is something we still don't understand.

After my mother died, I lived with relatives. Reading was a means of escaping into other worlds, as photography, much later, was to become.

We don't understand what photography is doing. We don't understand the power of its rhetoric. We don't understand why the Provoke photographers showed Tokyo city as a ghastly and alien city when it was really going through this period of mega-capitalist growth. It's a very, very, very powerful force, the photograph. People ask me why it has such an ability to captivate us. And I just don't know.

There was as big a reaction after the revelations about Assad's chemical weapons. Nevertheless, that photograph did strike a singular chord. Which leads us to a larger fact: we don't understand why certain photographs create such an upheaval in one's soul. You look at them and go, "Oh my gosh." And that doesn't happen with television. It's unique to photography. Photographs are unique in that they are a frame abstracted out of reality, out of, in this case, a civil war. A single event can carry so much weight. And that is extraordinary.

I think, oddly, that the world of the amateur is quite self-contained, and it depends on "likes" from other amateurs to perpetuate itself. Of course an awful lot of my colleagues are involved with Instagram - they get likes and dislikes, maybe just likes, I don't know - but I think that it's far less self-contained, the world I work in. It goes off in different directions, and is dependent on responses different from a tick or a like or whatever.

It's quite difficult to write about photography as a photographer. A lot of better photographers than me have declined to do it.

Reading is always a way of forming a bond with other people. I'm not very good at socializing - I quite like spending time alone - so reading is a way of engaging quite deeply with the way other people think. Quite often when you meet other people socially you don't get to have a conversation of any depth. You end up talking about how well or how badly someone is doing at school or something of that sort. Questions like, "What we are," "Who we are," "Where are we going," you get those from literature and from people that spend some time thinking.
