As human beings, don't we need questions without answers as well as questions with answers, questions that we might someday answer and questions that we can never answer?

What sense is there in continuing when one has seen the future?

Einstein's Dreams
Thoughts are no more than electrical surges in the brain. Sexual arousal is no more than a flow of chemicals to certain nerve endings. Sadness is no more than a bit of acid transfixed in the cerebellum. In short, the body is a machine, subject to the same laws of electricity and mechanics as an electron or clock.

Einstein's Dreams
So many little lives, amounting to nothing. I ask you: What is infinity multiplied by zero? It is hardly worth our discussion.

Mr G: A Novel About the Creation
Don't you feel something magical when you're in love?... I do, I certainly do ... but I think that feeling of magic is a hardwired psychological response. It's a chemical thing in the brain. It's a flow of chemicals and electrical currents, and it developed over millions of years in the process of evolution to aid in the procreation of the species.

If a person holds no ambitions in this world, he suffers unknowingly. If a person holds ambitions, he suffers knowingly, but very slowly.

Einstein's Dreams
Our comfort with nature is an illusion. Here on earth, even with our earthquakes and storms, we have no conception of the range and the power of nature. In many other parts of the cosmos, conditions are far more extreme than on earth and quite inhospitable to life. On the planet Mercury, for example, the temperature reaches 800 degrees. On Neptune, it is minus 370. On Uranus, the winds exceed 350 miles per hour. With the recent work of the Kepler spacecraft, searching for planets favorable for life, we can estimate that only about one millionth of one billionth of 1 percent of the material of the visible universe exists in living form. From a cosmic perspective, we and all life are the exception to the rule.

"Our Lonely Home in Nature", The New York Times, May 2, 2014
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.
