" [W]e may now be on the threshold of a new kind of genetic takeover. DNA replicators built 'survival machines' for themselves — the bodies of living organisms including ourselves. As part of their equipment, bodies evolved onboard computers — brains. Brains evolved the capacity to communicate with other brains by means of language and cultural traditions. But the new milieu of cultural tradition opens up new possibilities for self-replicating entities. The new replicators are not DNA and they are not clay crystals. They are patterns of information that can thrive only in brains or the artificially manufactured products of brains — books, computers, and so on. But, given that brains, books and computers exist, these new replicators, which I called memes to distinguish them from genes, can propagate themselves from brain to brain, from brain to book, from book to brain, from brain to computer, from computer to computer.

" What, after all, is so special about genes? The answer is that they are replicators. The laws of physics are supposed to be true all over the accessible universe. Are there any principles of biology which are likely to have similar universal validity? When astronauts voyage to distant planets and look for life, they can expect to find creatures too strange and unearthly for us to imagine. But is there anything which must be true of all life, wherever it is found, and whatever the basis of its chemistry? If forms of life exist whose chemistry is based on silicon rather than carbon, or ammonia rather than water, if creatures are discovered which boil to death at -100 degrees centigrade, if a form of life is found which is not based on chemistry at all, but on electronic reverberating circuits, will there still be any general principle which is true of all life? Obviously I do not know but, if I had to bet, I would put my money on one fundamental principle. This is the law that all life evolves by the differential survival of replicating entities. The gene, the DNA molecule, happens to be the replicating entity which prevails on our own planet. There may be others. If there are, provided certain conditions are met, they will almost inevitably tend to become the basis for an evolutionary process. "

" Every day, hundreds of observations and experiments pour into the hopper of the scientific literature. Many of them don't have much to do with evolution - they're observations about the details of physiology, biochemistry, development, and so on - but many of them do. And every fact that has something to do with evolution confirms its truth. Every fossil that we find, every DNA molecule that we sequence, every organ system that we dissect, supports the idea that species evolved from common ancestors. Despite innumerable possible observations that could prove evolution untrue, we don't have a single one. We don't find mammals in Precambrian rocks, humans in the same layers as dinosaurs, or any other fossils out of evolutionary order. DNA sequencing supports the evolutionary relationships of species originally deduced from the fossil record. And, as natural selection predicts, we find no species with adaptations that only benefit a different species. We do find dead genes and vestigial organs, incomprehensible under the idea of special creation. Despite a million chances to be wrong, evolution always comes up right. That is as close as we can get to a scientific truth. "

" Sometimes I look out the window out into the big, bright world and stare at people. Passers-by who live their ordinary lives and experience a full range of extraoridnary emotions. I stare at them for minutes, sometimes hours and then it makes me think, it makes me wonder. Are there people who are born healthy, who are born perfectly normal yet there is something wrong with them? Something nobody feels, nobody understands or questions, something that no one has ever even heard of? What if there are people among us who are capable of truly falling for someone, who are - in all biological, emotional, hormonal, chemical, philosophical senses - capable of loving someone with romantic love but no one in this wide world is capable of requiting that? Is it possible? Is it the fault of that person? Is it perhaps in the genes, the very DNA of someone? Is it perhaps destiny? And those passers-by go along happily without knowing anyone has ever asked something like this and they will probably never think about anything such because there might be only one person in this world who has to experience the feeling, the feeling that is so deeply rooted in a life alone.
