I have for a long time loved fabulist, imaginative fiction, such as the writing of Italo Calvino, Jose Saramago, Michael Bulgakov, and Salman Rushdie. I also like the magic realist writers, such as Borges and Marquez, and feel that interesting truths can be learned about our world by exploring highly distorted worlds.

As a scientist, I don't believe science will ever discover whether God exists. Nor do I believe religion will ever prove it.

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.

Human beings consider themselves satisfied only compared to some other condition. A man who has owned nothing but a bicycle all of his life feels suddenly wealthy the moment he buys an automobile...But this happy sensation wears off. After a while the car becomes just another thing that he owns. Moreover, when his neighbor next door buys two cars, in an instant our man feels wretchedly poor and deprived.

I've taken a philosophical position on e-mail. Although I think it's a wonderful communication technology, and it has a lot of good uses, it is abused quite a lot.

One cannot walk down an avenue, converse with a friend, enter a building, browse beneath the sandstone arches of an old arcade without meeting an instrument of time. Time is visible in all places. Clock towers, wristwatches, church bells divide years into months, months into days, days into hours, hours into seconds, each increment of time marching after the other in perfect succession. And beyond any particular clock, a vast scaffold of time, stretching across the universe, lays down the law of time equally for all.

In this world, there are two times. There is mechanical time and there is body time. The first is as rigid and metallic as a massive pendulum of iron that swings back and forth, back and forth, back and forth. The second squirms and wriggles like a bluefish in a bay. The first is unyielding, predetermined. The second makes up its mind as it goes along.
