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.
Alan LightmanOne metaphor for how we are living is that you see so may people with cell phones. In restaurants, walking, they have cell phones clamped to their to heads. When they are on their cell phones they are not where their bodies are...they are somewhere else in hyperspace. They are not grounded. We have become disembodied. By being always somewhere else we are nowhere.
Alan LightmanOne 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.
