“I'd like to widen people's awareness of the tremendous timespan lying ahead--for our planet, and for life itself. Most educated people are aware that we're the outcome of nearly 4bn years of Darwinian selection, but many tend to think that humans are somehow the culmination. Our sun, however, is less than halfway through its lifespan. It will not be humans who watch the sun's demise, 6bn years from now. Any creatures that then exist will be as different from us as we are from bacteria or amoebae.”

“The rock, for its part, is not even aware of our existence because we are alive for only a brief instant of its lifespan. To it, we are like flashes in the dark.”

“If the human species is differentiated from the beasts by the marvel of consciousness, then we enact our humanity and the very authenticity of our being by straining to "know" through awareness the "unthinkable" experience of others.”

“It is unlikely that many people will take to heart the conclusion that coming into existence is always a harm. It is even less likely that many people will stop having children. By contrast, it is quite likely that my views either will be ignored or will be dismissed. As this response will account for a great deal of suffering between now and the demise of humanity, it cannot plausibly be thought of as philanthropic. That is not to say that it is motivated by any malice towards humans, but it does result from a self-deceptive indifference to the harm of coming into existence.”

“Our self-awareness impresses itself on us so cogently, as individuals and as a species, that we cannot imagine ourselves out of existence, even though for hundreds of millions of years humans played no part in the flow of life on the planet. When Teilhard de Chardin wrote, "The phenomenon of Man was essentially foreordained from the beginning," he was speaking from the depth of individual experience, which we all share, as much as from religious philosophy. Our inability to imagine a world without Homo sapiens has a profound impact on our view of ourselves; it becomes seductively easy to imagine that our evolution was inevitable. And inevitability gives meaning to life, because there is a deep security in believing that the way things are is the way they were meant to be.”

“Books permit us to voyage through time, to tap the wisdom of our ancestors. The library connects us with the insight and knowledge, painfully extracted from Nature, of the greatest minds that ever were, with the best teachers, drawn from the entire planet and from all our history, to instruct us without tiring, and to inspire us to make our own contribution to the collective knowledge of the human species. I think the health of our civilization, the depth of our awareness about the underpinnings of our culture and our concern for the future can all be tested by how well we support our libraries.”
