Mystery of mysteries, water and air are right there before us in the sea. Every time I view the sea, I feel a calming sense of security, as if visiting my ancestral home; I embark on a voyage of seeing.

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.

Population diminishing, even in Japan and Italy, the population is diminishing. When society can reach a sustainable place or gain comfortable income, then people tend to have fewer children.

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?

Maybe we wait for another 100,000 years and then apes get consciousness.
