Yeah, epigenetics. Even more to the point. Essentially what i mean with the phrase 'epidemiology of experience'. Nurturing by environment that can cause interference with how genes are expressed; both our prince and our slave are healthy, but our aristocrat ends up acting like a pansy and our slave, like a badass. In other words:
"Proper instincts are acquired through millennia of brutal, tyrannic imposition of a morality"
Impose all u want, but that won't guarantee any success in what u are attempting to build/breed through such stringent culturing. At an epigenetic level, controlling the circumstances and factors that cause genes to turn on or off (while the DNA stays the same) would be practically impossible. Moreover, it's not entirely accurate to say that 'memes' are the causal agents in effecting and changing gene expression... simply becuz ideas don't, can't, effect physical properties. Indirectly, however, this may happen tho. Say u have a cultural behavior (a meme) that, by being practiced, exposes the individual to environmental factors that effect him epigenetically; smoking cigarettes is cool in culture x, and doing so results in gene expression changes that bring about cancer. Okay... but the meme
didn't cause the cancer. It was the chemicals in the cigarettes that caused the cancer... and this is a factor of the environment (the tobacco), not the culture of smoking.
And this is not a minor technical difference. It means everything concerning the veracity of memes. Add to this the immense complexity and unpredictability of gene activity in their interactions with environments - which genes get turned on and off, and why - and memes become even more ambiguous.
"Ah, but I don't want that; not yet, not for a couple of millennia, at least..."
Why on earth would u say such a thing?!
Do it right here and now. It means everything...
