Where do you draw the line as a human being? Written record is only, what, a couple thousand years? And this scientific revolution is less than a hundred years. And computers only a few decades! We've changed so much. It's amazing, the speed of changes.

When people call me a photographer, I always feel like something of a charlatan—at least in Japanese. The word shashin, for photograph, combines the characters sha, meaning to reflect or copy, and shin, meaning truth, hence the photographer seems to entertain grand delusions of portraying truth.

All over the planet, nature is being transformed into 'un-nature' at breakneck speed...My life is part of natural history. I long to know where that history came from and where it is going.

I want to put it back together now, this artistic expression that contains religious feeling. I want to investigate: What was the origin? What's happened in the human mind? Can we trace back the moment of the creation of human consciousness? And why did only humans gain consciousness, not other animals? So, evolution? I don't know whether or not I can believe evolution. Maybe we wait for another 100,000 years and then apes get consciousness.

I don't love the postmodern statement: "You shouldn't be spiritual if you are the artist."

Photography is like a found object. A photographer never makes an actual subject; they just steal the image from the world... Photography is a system of saving memories. It's a time machine, in a way, to preserve the memory, to preserve time.

The Buddhist concept is that it takes 48 days to get near this state [of death]. So it's a slow process, moving into, not a permanent death, but the world of the dead.
