Richard Dawkins

Dawkins is a brilliant writer and speaker on science. His grasp of the subject and his use of vivid analogies can explain scientific concepts and make them clear even for the non-scientist...

Think about the two qualities that a virus, or any sort of parasitic replicator, demands of a friendly medium, the two qualities that make cellular machinery so friendly towards parasitic DNA, and that make computers so friendly towards computer viruses. These qualities are, firstly, a readiness to replicate information accurately, perhaps with some mistakes that are subsequently reproduced accurately; and, secondly, a readiness to obey instructions encoded in the information so replicated.

... it seems that it would take less than half a million years to evolve a good camera eye ... It's no wonder "the" eye has evolved at least 40 times independently around the animal kingdom ... It is a geological blink.

And when we look closely, we find a system of morals which any civilised person today should surely find poisonous.

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.

Oh, but of course the story of Adam and Eve was only ever symbolic, wasn't it? Symbolic?! So Jesus had himself tortured and executed for a symbolic sin by a non-existent individual? Nobody not brought up in the faith could reach any verdict other than "barking mad". (Part 2, 00:30:25)

Another force driving progressive evolution is the so-called "arms-race." Prey animals evolve faster running speeds because predators do. Consequently predators have to evolve even faster running speeds, and so on, in an escalating spiral. Such arms races probably account for the spectacularly advanced engineering of eyes, ears, brains, bat "radar" and all the other high-tech weaponry that animals display.

Darwin made it possible to be an intellectually fulfilled atheist.

Religion is about turning untested belief into unshakable truth through the power of institutions and the passage of time.

If the alternative that's being offered to what physicists now talk about - a big bang, a spontaneous singularity which gave rise to the origin of the universe - if the alternative to that is a divine intelligence, a creator, which would have to have been complicated, statistically improbable, the very kind of thing which scientific theories such as Darwin's exists to explain, then immediately we see that however difficult and apparently inadequate the theory of the physicists is, the theory of the theologians - that the first course was a complicated intelligence - is even more difficult to accept. They’re both difficult but the theory of the cosmic intelligence is even worse. What Darwinism does is to raise our consciousness to the power of science to explain the existence of complex things and intelligences, and creative intelligences are above all complex things, they’re statistically improbable. Darwinism raises our consciousness to the power of science to explain how such entities - and the human brain is one - can come into existence from simple beginnings. However difficult those simple beginnings may be to accept, they are a whole lot easier to accept than complicated beginnings. Complicated things come into the universe late, as a consequence of slow, gradual, incremental steps. God, if he exists, would have to be a very, very, very complicated thing indeed. So to postulate a God as the beginning of the universe, as the answer to the riddle of the first cause, is to shoot yourself in the conceptual foot because you are immediately postulating something far far more complicated than that which you are trying to explain. Now, physicists cope with this problem in various ways, which may seem somewhat unconvincing. For example, they suggest that our universe is but one bubble in foam of universes, the multiverse, and each bubble in the foam has a different set of laws and constants. And by the anthropic principle we have to be - since we’re here talking about it - in the kind of bubble, with the kind of laws and constants, which are capable of giving rise to the evolutionary process and therefore to creatures like us. That is one current physicists’ explanation for how we exist in the kind of universe that we do. It doesn’t sound so shatteringly convincing as say Darwin’s own theory, which is self-evidently very convincing. Nevertheless, however unconvincing that may sound, it is many, many, many orders of magnitude more convincing than any theory that says complex intelligence was there right from the outset. If you have problems seeing how matter could just come into existence - try thinking about how complex intelligent matter, or complex intelligent entities of any kind, could suddenly spring into existence, it’s many many orders of magnitude harder to understand.

I don't believe you until you tell me, do you really believe, for example, if they say they are Catholic, "Do you really believe that when a priest blesses a wafer, it turns into the body of Christ? Are you seriously telling me you believe that? Are you seriously saying that wine turns into blood?" Mock them. Ridicule them. In public. Don't fall for the convention that we're all too polite to talk about religion. Religion is not off the table. Religion is not off limits. Religion makes specific claims about the universe which need to be substantiated and need to be challenged and, if necessary, need to be ridiculed with contempt.

I think it is not helpful to apply Darwinian language too widely. Conquest of nation by nation is too distant for Darwinian explanations to be helpful. Darwinism is the differential survival of self-replicating genes in a gene pool, usually as manifested by individual behaviour, morphology, and phenotypes. Group selection of any kind is not Darwinism as Darwin understood it nor as I understand it. There is a very vague analogy between group selection and conquest of a nation by another nation, but I don't think it's a very helpful analogy. So I would prefer not to invoke Darwinian language for that kind of historical interpretation.

Once again, modern theologians will protest that the story of Abraham sacrificing Isaac should not be taken as literal fact. And, once again, the appropriate response is twofold. First, many many people, even to this day, do take the whole of their scripture to be literal fact, and they have a great deal of political power over the rest of us, especially in the United States and in the Islamic world. Second, if not as literal fact, how should we take the story? As an allegory? Then an allegory for what? Surely morals could one derive from this appalling story? Remember, all I am trying to establish for the moment is that we do not, as a matter of fact, derive our morals from scripture. Or, if we do, we pick and choose among the scriptures for the nice bits and reject the nasty. But then we must have some independent criterion for deciding which are the moral bits: a criterion which, wherever it comes from, cannot come from scripture itself and is presumably available to all of us whether we are religious or not.

The truth is that all examples of child protection and parental care, and all associated bodily organs ... are examples of the working in nature of the kin-selection principle.

Pantheism is sexed-up atheism. Deism is watered-down theism. (pg. 40)

The God of the Old Testament is arguably the most unpleasant character in all fiction: jealous and proud of it; a petty, unjust, unforgiving control-freak; a vindictive, bloodthirsty ethnic cleanser; a misogynistic, homophobic, racist, infanticidal, genocidal, filicidal, pestilential, megalomaniacal, sadomasochistic, capriciously malevolent bully. (pg. 31)

I want to examine that dangerous thing that’s common to Judaism and Christianity as well: the process of non-thinking called "faith". (Part 1, 00:00:55)

"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." (pg.178)

Reason has built the modern world. It is a precious but also a fragile thing, which can be corroded by apparently harmless irrationality. We must favor verifiable evidence over private feeling. Otherwise we leave ourselves vulnerable to those who would obscure the truth.

If you want to do evil, science provides the most powerful weapons to do evil; but equally, if you want to do good, science puts into your hands the most powerful tools to do so. The trick is to want the right things, then science will provide you with the most effective methods of achieving them.
