Means of Penetration for Memes

We looked at three methods of penetration: repetition, cognitive dissonance, and the Trojan horse. When a virus of the mind infects you, it may resemble one of these scenarios: - Repetition. Repeating a meme until it becomes familiar and part of your programming is one method of mind-virus penetration: • Hearing a…

An Origami Metaphor for Fetal Development

The sheets of tissue that fold, invaginate and turn inside out in a developing embryo do indeed grow, and it is that very growth that provides part of the motive force which, in origami, is supplied by the human hand. If you wanted to make an origami model with a sheet of living tissue instead of dead paper, there is…

DNA as an Archive of the Past

Each individual's genome, in any one generation, will be a sample from the species database. Different species will have different databases because of their different ancestral worlds. The database in the gene pool of camels will encode information about deserts and how to survive in them. The DNA in mole gene pools…

Skeletal Similarities in Mammals

What a piece of work is the mammalian skeleton. I don't mean it is beautiful in itself, although I think it is. I mean the fact that we can talk about 'the' mammalian skeleton at all: the fact that such a complicatedly interlocking thing is so gloriously different across the mammals, in all its parts, while…

Genes are Under Constant Attack

Every animal and plant genome is subject to a constant bombardment of deleterious mutations: a hailstorm of attrition. It is a bit like the moon's surface, which becomes increasingly pitted with craters due to the steady bombardment of meteorites. With rare exceptions, every time a gene concerned with an eye, for…

Caenorhabditis elegans

Caenorhabditis elegans was chosen in the 1960s as an ideal experimental animal by the formidably brilliant South African biologist Sydney Brenner. He had recently completed his work, with Francis Crick and others at Cambridge, on cracking the genetic code, and was looking around for a new big problem to solve. His…

Mendelian Genes are All-Or-Nothing

A Mendelian gene is an all-or-nothing entity. When you were conceived, what you received from your father was not a substance, to be mixed with what you received from your mother as if mixing blue paint and red paint to make purple. If this were really how heredity worked (as people vaguely thought in Darwin's time)…

Absolute Certainty Will Always Elude Us

There is much that science doesn't understand, many mysteries still to be resolved. In a Universe tens of billions of light years across and some ten or fifteen billion years old, this may be the case forever. We are constantly stumbling on surprises. Yet some New Age and religious writers assert that scientists…

Genes versus Hormones in Homosexuality

It is clear, however, that the cause of homosexuality lies in some unusual balance of hormonal influence in the womb but not later on, a fact that further supports the idea that the mentality of sexual preference is affected by prenatal sex hormones. This is not incompatible with the growing evidence that…

Mullet's Ratchet

In recent years the geneticists have turned away from good mutations and begun to think about bad ones. Sex, they suggest, is a way of getting rid of bad mutations. This idea also has its origins in the 1960s, with Hermann Muller, one of the fathers of the Vicar of Bray theory. Muller, who spent much of his career at…

We Inherit from Our Parent's Zygotes

It IS a mistake that biologists used to make, too. They believed that evolution proceeded by accumulating the changes that individuals gathered during their lives. The idea was most clearly formulated by Jean-Baptiste Lamarck, but Charles Darwin sometimes used it, too. The classic example is a blacksmith's son…

Bernie Cosell on Java

Java didn't feel right. My old reflexes hit me. Java struck me as too authoritarian. Thats one of the reasons why I mentioned that Perl felt so good, because it's got the safety and the checks but it is so damn multidimensioned that the artist part of me has a lot of free board to express things early and to think…

Humans Are Strong, Civilization is Fragile

We have confidence in our science-based civilization and think it has tenure. In so doing, I think we fail to distinguish between the life-span of civilizations and that of our species. In fact, civilizations are ephemeral compared with species. Humans have lasted at least a million years, but there have been 30…

Science VS Belief

Science seeks the truth. And it does not discriminate. For better or worse it finds things out. Science is humble. It knows what it knows and it knows what it doesn’t know. It bases its conclusions and beliefs on hard evidence -­- evidence that is constantly updated and upgraded. It doesn’t get offended when new facts…

Good Replicators have Fidelity, Fecundity, and Longevity

Effective memes will be those that cause high fidelity, long-lasting memory. Memes may be successful at spreading largely because they are memorable rather than because they are important or useful. Wrong theories in science may spread simply because they are comprehensible and fit easilty with existing theories, and…

Campbell's Rule of Design Through Evolution

We should think of it like this - evolutionary theory describes how design is created by the competition between replicators. Genes are one example of a replicator and memes another. The general theory of evolution must apply to both of them, but the specific details of how each replicator works may be quite…

A Succinct Definition of a Meme

For something to count as a replicator it must sustain the evolutionary algorithm based on variation, selection and retention (or heredity). Memes certainly come with variation - stories are rarely told exactly the same way twice, no two buildings are absolutely identical, and every conversation is unique - and when…

Economics is Merely Psychology

In Utopia there is no distinct and separate science of economics. Many problems that we should regard as economic come within the scope of Utopian psychology. My Utopians make two divisions of the science of psychology, first, the general psychology of individuals, a sort of mental physiology separated by no definite…

We Cannot Trend How Our Reasoning May Go

There is no abiding thing in what we know. We change from weaker to stronger lights, and each more powerful light pierces our hitherto opaque foundations and reveals fresh and different opacities below. We can never foretell which of our seemingly assured fundamentals the next change will not affect. What folly, then…
