Photography is essentially an act of recognition by street photographers, not an act of invention. Photographers might respond to an old man’s face, or an Arbus freak, or the way light hits a building—and then they move on. Whereas in all the other art forms, take William Blake, everything that came to that paper never existed before. It’s the idea of alchemy, of making something from nothing.

The real world is in a much darker and deeper place than this, and most of it is occupied by jellyfish and things. We just happen to to forget all that. Don't you agree? Two-thirds of earth's surface is ocean, and all we can see with the naked eye is the surface: the skin.

A photograph of a woman crying tells me nothing about grief. Or a photograph of a woman ecstatic tells me nothing about ecstasy. What is the nature of these emotions? The problem with photography is that it only deals with appearances.

What lies behind the innocent looks? What lies behind the kind words? What lies behind the gentle smiles? Do not remain on the surface of the things; go behind them so that you can compare the seen with the unseen, the surface with the depth to find out whether they are the same or not!

I would like to start by emphasizing the importance of surfaces. It is at a surface where many of our most interesting and useful phenomena occur. We live for example on the surface of a planet. It is at a surface where the catalysis of chemical reactions occur. It is essentially at a surface of a plant that sunlight is converted to a sugar. In electronics, most if not all active circuit elements involve non-equilibrium phenomena occurring at surfaces. Much of biology is concerned with reactions at a surface.

But it wasn't the right season to lift off. Not yet. I sat in my apartment and looked out over the city, and I just didn't feel any passion to write about the place. I didn't give a damn about local politics; I wasn't moved by the issues. I missed home. And I was frustrated by people who actually thought the world was a centre and that centre was here. ‘The world's a sphere, everyone,’ I wanted to say. ‘The centre of a sphere doesn't lie on its surface. Look up the word 'superficial', when you have a chance.
