The question was: why you think scientific explanation and teleological explanation are mutually incompatible? I asked several times, in Post
96 for example.
Genetic code does not have a 'goal', unless you wish to re-subscribe to teleology once again. That's a retrospective purposive illusion.
This I disagree with this, and this disagreement illustrates what I think is the core of your misunderstanding. Genetic code <b>does</b> have replication as its purpose.
But it all depends on the semantics of "goal" or "purpose": If you assume by fiat that only humans can have goals or purposes, then you are trivially right, but I take these terms to have more genereal meaning (as pointed out in earlier postings): a system S has a goal G, if S contains within itself a representation of G and organises its behaviour in the face of perturbations from the environment so as to reach G. The study of such "teleological mechanisms" has been termed
Cybernetics by Norbert Wiener, although that name is no longer in fashion. In that sense genes clearly have the goal of self-replication, as they contain a blueprint that describes themselves and guides their self-reproduction. That
- self-replication is possible as a purely mechanical natural (or blind) process, and
- that this process evolved purely out of the chaos of matter moving about (order-from noise!)
is one of the amazing empirical discoveries of 20th century science. Maybe it's time for you to divulge what you mean by "purpose, goal, telos".
Here is an example of a
self replicating computer program (called Church's Y-Combinator):
(f(xx)))(λx.(f(xx))))
Here is another one:
char*f="char*f=%c%s%c;main() {printf(f,34,f,34,10);}%c"; main(){printf(f,34,f,34,10);}
I could go and use an alternative description, like "these programs print something on screen, and otherwise just blindly executes", but what is the interest in this latter description? It's trivial and says nothing, i.e. it carries no information. It misses the fundamental fact that the programs do contain self-description and hence have
the purpose of self-replication (when operating in a suitable environment). This peculiar goal informes their structure, in fact their structure is dominated by this goal. Once one understands the goal of self-replication, one can ask scientific questions about the nature of self-replication: what features do all self-replicating entities have in common etc.
The mistake you make, I believe, is that you automatically assume that every goal has to have a sentient being having this goal. Hence you think that when scientists describe the goal of evolution as (for example) replication of genes, they assume or imply that there are sentinent beings holding that goal in their heads. This ain't so. Matter can organise itself into causally active representations of future states (aka goals). It's amazing, and may be hard to comprehend, but still true.
What's it called 'evolutionary psychology' for, then, and not, say, evolutionary/genetic human biology (or biosocial engineering)?
Your point being?
And aren't you depoliticizing here somewhat? ["No, it's not the debilitating social anxiety resulting from having lost his job, from having no say in his socio-economic environment, it's a chemical inbalance in his BRAIN and all we gotta do is find the rogue gene that's responsible, the little bugger, and that other one that's causing him to get strange ideas about his boss' offshore bank accounts, and yeah his sexual orientation too ..."]. BF Skinner is wetting himself.
And aren't you depoliticizing here somewhat? ["No, his need to breathe is not resulting from the sustained pysiological need for oxygen and from having no say in the creation of his biological makeup, it's all capitalism's fault that he needs to eat. All that evil advertising created the libidinal structure that sets up the postmodern superego constantly commanding him to breathe! It's the debilitating social anxiety resulting from having lost his job, from having no say in his socio-economic environment, that makes him crave air, and all we gotta do is find the rogue banker responsible, the little bugger, and that other one that's causing him to get strange ideas about his eating thrice a day, and yeah about wanting to have sexual too ..."]. Pol Pot is wetting himself.
Let me repeat, the point of studying EP is in essence <B>to determine which parts of human behavoir are socially acquired and which parts are not</B>. This has interesting political ramifications: that homosexuality is probably innate while a propensity for crime is not, are highlights of this research tradition.
I have, funnily enough. And, you know, sorry to have to break it to you like this, but it's complete nonsense.
What is nonsense? Nietzsche's linear narrative? Or the suggestion that it might be inappropriate? If the latter, would you care to venture substantive points supporting your positions?
Have you ever heard of capitalism?
Yes. In my experience, when this term is used (by Libertarians or Marxists-Stalinists), what is being said is rarely interesting. It's a marker for lack of though. Anyway, but not unrelated: what's the connection between Nietzsche's narrative and capitalism? Are you saying that Captialism = God? Or that Captialism = Death of God? And how does any of this connect with the historical accuracy of this narrative, in the light of the fact that religion as we understand it now, is probably a relatively phenomenon, which gained mass currency only after the invention of the printing press?
[like, more children are currently starving and/or diseased than at any time in recorded history?]
Interesting. I don't believe that this is true at all in any substantial sense. It's just wishful thinking on your part! The bare fact that humans live much longer than at any time in human history is fairly compelling evidence to the contrary.
