Notes
Cultural transmission and evolution is not unique to man
(e.g. bird-song dialects), but is obviously much more complex and thorough in
our case.
As in genetic evolution, cultural change may be progressive
(e.g. improvements in science)
Replication and differentiation are the keys to evolution.
Genes just happen to be the means by which life on this planet evolve.
Similarly, memes are the equivalent of genes for cultural transmission
and evolution.
Memes are physically instantiated in our nervous systems.
Wow, Dawkins really beat me to
the punch here. For a while, I actually believed this was my idea. Obviously,
it’s just a meme I inherited from him somehow. But I think his work can still be extended, by looking at the
relationship between network society and meme distribution and evolution.
Keys to meme survival are the same as those for genes:
longevity, fecundity, and copying-fidelity.
If memes seem to have low copying-fidelity, maybe that is
because they are compound memes. Analogy: interracial couple has a baby which
seems to “blend” the racial traits. In reality, the genes aren’t blending,
there are just a large number of them with complex emergent properties.
The same may be inferred for memes.
Although there is no equivalent of chromosomes in the world
of memes, they are still competitive. The limiting factors are time and storage
space – both in the human nervous system and in the media. Wonder how the explosion of media storage space and
acceleration of transmission speeds affects the nature of this competition.
Memes can be self-perpetuating and mutually reinforcing,
e.g. “god” and “hell”
Quotes
“Language seems to ‘evolve’ by non-genetic means, and at a
rate which is orders of magnitude faster than genetic evolution.” (189)
“for an understanding of the evolution of modern man, we
must begin by throwing out the gene as the sole basis of our ideas of
evolution.” (191) this is refreshing, given our
genetically deterministic tendencies today.
“all life evolves by the differential survival of
replicating entities” (192)
“Just as genes propagate themselves in the gene pool by
leaping from body to body via sperms or eggs, so memes propagate themselves in
the meme pool by leaping from brain to brain via a process which, in the broad
sense, can be called imitation.” (192) thesis
statement
“the survival value of the god meme in the meme pool results
from its great psychological appeal.” (193)
“Whenever conditions arise in which a new kind of replicator
can make copies of itself, the new replicators will tend to take
over, and start a new kind of evolution on their own.” (193)
“An ‘idea-meme’ might be defined as an entity that is
capable of being transmitted from one brain to another.” (196)
“a cultural trait may have evolved in the way that it has,
simply because it is advantageous to itself.” (200) this is a really important point.
“We are built as gene machines and cultured as meme
machines, but we have the power to turn against our creators. We, alone on
earth, can rebel against the tyranny of the selfish replicators.” (201)
