“The illusion is irresistible. Behind every face there is a self. We see the signal of consciousness in a gleaming eye and imagine some ethereal space beneath the vault of the skull, lit by shifting patterns of feeling and thought, charged with intention. An essence. But what do we find in that space behind the face, when we look? The brute fact is there is nothing but material substance: flesh and blood and bone and brain…You look down into an open head, watching the brain pulsate, watching the surgeon tug and probe, and you understand with absolute conviction that there is nothing more to it. There’s no one there.”

“A three-day-old human embryo is a collection of 150 cells called a blastocyst. There are, for the sake of comparison, more than 100,000 cells in the brain of a fly. The human embryos that are destroyed in stem-cell research do not have brains, or even neurons. Consequently, there is no reason to believe they can suffer their destruction in any way at all. It is worth remembered, in this context, that when a person's brain has died, we currently deem it acceptable to harvest his organs (provided he has donated them for this purpose) and bury him in the ground. If it is acceptable to treat a person whose brain has died as something less than a human being, it should be acceptable to treat a blastocyst as such. If you are concerned about suffering in this universe, killing a fly should present you with greater moral difficulties than killing a human blastocyst.

Perhaps you think that the crucial difference between a fly and a human blastocyst is to be found in the latter's potential to become a fully developed human being. But almost every cell in your body is a potential human being, given our recent advances in genetic engineering. Every time you scratch your nose, you have committed a Holocaust of potential human beings.”

“It is time we admitted, from kings and presidents on down, that there is no evidence that any of our books was authored by the Creator of the universe. The Bible, it seems certain, was the work of sand-strewn men and women who thought the earth was flat and for whom a wheelbarrow would have been a breathtaking example of emerging technology. To rely on such a document as the basis for our worldview-however heroic the efforts of redactors- is to repudiate two thousand years of civilizing insights that the human mind has only just begun to inscribe upon itself through secular politics and scientific culture. We will see that the greatest problem confronting civilization is not merely religious extremism: rather, it is the larger set of cultural and intellectual accommodations we have made to faith itself.”

“Evolution can even explain how our behaviors interact. Remember how the amygdala can suppress higher brain functions—for example, in the expression “His mind was clouded by fear.” This is manifestly irrational behavior, but it makes perfect sense from an evolutionary standpoint. Strong emotions like fear are an immediate call-to-arms to survive, selected by evolution over millions of generations of life in hostile environments. Our more recently evolved cognitive functions, such as language and logical reasoning, are suppressed until the perceived threat to our survival is over, that is, until our emotional reaction subsides. The universality of this fear response means that fear has been so useful in past environments that it has evolved to override all other neural components under sufficient threat.”
