Richard Dawkins on Life

"No doubt some of your cousins and great-uncles died in childhood, but not a single one of your ancestors did. Ancestors just don't die young!"

"I cannot know for certain but I think God is very improbable, and I live my life on the assumption that he is not there."

"The meme for blind faith secures its own perpetuation by the simple unconscious expedient of discouraging rational inquiry."

"However many ways there may be of being alive, it is certain that there are vastly more ways of being dead."

"We no longer have to resort to superstition when faced with the deep problems: Is there a meaning to life? What are we for? What is man?"

"It's obvious that in an intelligent educated audience such as this university, I stress this university. Who saw fit to give them accreditation?"

"Most of what we strive for in our modern life uses the apparatus of goal seeking that was originally set up to seek goals in the state of nature."

"There is no spirit-driven life force, no throbbing, heaving, pullulating, protoplasmic, mystic jelly. Life is just bytes and bytes and bytes of digital information."

"... the genetic code is in fact literally identical in all animals, plants and bacteria ... All earthly living things are certainly descended from a single ancestor."

"A God capable of continuously monitoring and controlling the individual status of every particle in the universe cannot be simple. His existence is going to need a mammoth explanation in its own right."

"Each generation is a filter, a sieve; good genes tend to fall through the sieve into the next generation; bad genes tend to end up in bodies that die young or without reproducing."

"... a gene might be able to assist replicas of itself that are sitting in other bodies. If so, this would appear as individual altruism but it would be brought about by gene selfishness."

"But it is we that choose to divide animals up into discontinuous species. On the evolutionary view of life there must have been intermediates, even though, conveniently for our naming rituals, they are usually extinct."

"There is one particular property of living things, however, that I want to single out as explicable only by Darwinian selection. This property is the one that has been the recurring topic of this book: adaptive complexity."

"... the true utility function of life, that which is being maximised in the natural world, is DNA survival. But DNA is not floating free; it is locked up in living bodies and it has made the most of the levers of power at its disposal."

"They are in you and me; they created us, body and mind; and their preservation is the ultimate rationale for our existence. They have come a long way, those replicators. Now they go by the name of genes, and we are their survival machines."

"Genes do indirectly control the manufacture of bodies, and the influence is strictly one way: acquired characteristics are not inherited. No matter how much knowledge and wisdom you acquire during your life, not one jot will be passed on to your children by genetic means. Each new generation starts from scratch."

"Let us try to teach generosity and altruism, because we are born selfish. Let us understand what our own selfish genes are up to, because we may then at least have a chance to upset their designs, something that no other species has ever aspired to do."

"In the case of the cosmos, even if we don't understand how it came about, it's not helpful to postulate a creator, because the creator is the very kind of thing that needs an explanation - and although it's difficult enough to explain how a very simple origin of the universe came into being - how matter and energy, how one or two physical constants came into existence - although it's difficult enough to think how simplicity came into existence, it's a hell of a lot harder to think how something as complicated as a God comes into existence - difficult enough to think of how a deist God comes into existence, and even more difficult to think of - how a Christian God, who actually cares about things like sin and gets Himself born of a virgin."

"There is something infantile in the presumption that somebody else has a responsibility to give your life meaning and point. The truly adult view, by contrast, is that our life is as meaningful, as full and as wonderful as we choose to make it. And we can make it very wonderful indeed."

"There is more than just grandeur in this view of life, bleak and cold though it can seem from under the security blanket of ignorance. There is deep refreshment to be had from standing up and facing straight into the strong keen wind of understanding: Yeats's 'Winds that blow through the starry ways'."

"The feeling of awed wonder that science can give us is one of the highest experiences of which the human psyche is capable. It is a deep aesthetic passion to rank with the finest that music and poetry can deliver. It is truly one of the things that make life worth living and it does so, if anything, more effectively if it convinces us that the time we have for living is quite finite."

"It is a very helpful insight to say we are vehicles for our DNA, we are hosts for DNA parasites which are our genes. Those are insights which help us to understand an aspect of life. But it's emotive to say, that's all there is to it, we might as well give up going to Shakespeare plays and give up listening to music and things, because that's got nothing to do with it. That's an entirely different subject."

"Natural selection, the blind, unconscious, automatic process which Darwin discovered, and which we now know is the explanation for the existence and apparently purposeful form of all life, has no purpose in mind. It has no mind and no mind's eye. It does not plan for the future. It has no vision, no foresight, no sight at all. If it can be said to play the role of watchmaker in nature, it is the blind watchmaker."

"Replicators are no longer peppered freely through the sea; they are packaged in huge colonies—individual bodies. And phenotypic consequences, instead of being evenly distributed throughout the world, have in many cases congealed into those same bodies. But the individual body, so familiar to us on our planet, did not have to exist. The only kind of entity that has to exist in order for life to arise, anywhere in the universe, is the immortal replicator."

"If we want to postulate a deity capable of engineering all the organized complexity in the world, either instantaneously or by guiding evolution, that deity must have been vastly complex in the first place. The creationist, whether a naive Bible-thumper or an educated bishop, simply postulates an already existing being of prodigious intelligence and complexity. If we are going to allow ourselves the luxury of postulating organized complexity without offering an explanation, we might as well make a job of it and simply postulate the existence of life as we know it!"

"We are going to die, and that makes us the lucky ones. Most people are never going to die because they are never going to be born. The potential people who could have been here in my place but who will in fact never see the light of day outnumber the sand grains of Arabia. Certainly those unborn ghosts include greater poets than Keats, scientists greater than Newton. We know this because the set of possible people allowed by our DNA so massively outnumbers the set of actual people. In the teeth of these stupefying odds it is you and I, in our ordinariness, that are here."

"Imagine you are God. You’re all-powerful, nothing is beyond you. You’re all-loving. So it is really, really important to you that humans are left in no doubt about your existence and your loving nature, and exactly what they need to do in order to get to heaven and avoid eternity in the fires of hell. It’s really important to you to get that across. So what do you do? Well, if you’re Jehovah, apparently this is what you do. You talk in riddles. You tell stories which on the surface have a different message from the one you apparently want us to understand. You expect us to hear X, and instinctively understand that it needs to be interpreted in the light of Y, which you happen to have said in the course of a completely different story 500-1,000 years earlier. Instead of speaking directly into our heads - which God has presumed the capability of doing so - simply, clearly and straightforwardly in terms which the particular individual being addressed will immediately understand and respond to positively - you steep your messages in symbols, in metaphors. In fact, you choose to convey the most important message in the history of creation in code, as if you aspired to be Umberto Eco or Dan Brown. Anyone would think your top priority was to keep generation after generation after generation of theologians in meaningless employment, rather than communicate an urgent life-or-death message to the creatures you love more than any other."

"The world and the universe is an extremely beautiful place, and the more we understand about it the more beautiful does it appear. It is an immensely exciting experience to be born in the world, born in the universe, and look around you and realise that before you die you have the opportunity of understanding an immense amount about that world and about that universe and about life and about why we're here. We have the opportunity of understanding far, far more than any of our predecessors ever. That is such an exciting possibility, it would be such a shame to blow it and end your life not having understood what there is to understand."

"You see, if you say something positive like the whole of life – all living things – is descended from a single common ancestor which lived about 4,000 million years ago and that we are all cousins, well that is an exceedingly important and true thing to say and that is what I want to say. Somebody who is religious sees that as threatening and so I am represented as attacking religion, and I am forced into responding to their reaction. But you do not have to see my main purpose as attacking religion. Certainly I see the scientific view of the world as incompatible with religion, but that is not what is interesting about it. It is also incompatible with magic, but that also is not worth stressing. What is interesting about the scientific world view is that it is true, inspiring, remarkable and that it unites a whole lot of phenomena under a single heading. And that is what is so exciting for me."
