For me, consciousness is the most interesting unsolved problem of science, and, in fact, we may never know what it is about a particular arrangement of neurons that gives rise to consciousness. Our consciousness, like the air we breathe or like the passage of time, is central to our existence as intelligent beings.

I value my correspondence with writers...I was in New York and had lunch with Oliver Sachs and compared notes with him - he is someone I really like. I love staying in written correspondence with some writers. That's enough for me.

I spend a lot of time just listening to the ospreys. I watch them go through their life cycle. They spend the winter in South America. The mother and father osprey stay together. It's a monogamous relationship. And every summer they raise a new brood of children. They came back to the nest in the middle of April. They take separate vacations in the winter - the mother and father.

Each time is true, but the truths are not the same.

A world in which time is absolute is a world of consolation. For while the movements of people are unpredictable, the movement of time is predictable. While people can be doubted, time cannot be doubted. While people brood, time skips ahead without looking back.

We often do not see what we do not expect to see.

Children grow rapidly, forget the centuries-long embrace from their parents, which to them lasted but seconds. Children become adults, live far from their parents, live their own houses, learn ways of their own, suffer pain, grow old. Children curse their parents for their wrinkled skin and hoarse voices. Those now old children also want to stop time, but at another time. They want to freeze their own children at the center of time.
