| | Nathan, I will answer Daniel first, as my answers to his specific inquiries may well answer your specific challenge to me. Just follow up if my answer to him doesn't satisfy your understanding of my position on the matter.
Daniel,
------------------ -- is not empirically falsifiable.
Hey, neither is Rand's theory of concept formation apparently (although I am very keen to hear of any empirical experiments you might suggest that could test it). Do you likewise have a problem with that theory? ------------------
No I don't have a problem with that theory -- as it has been offered (in a specific means and with a specific objective -- ie. explaining that which is irreducible --ie. explain that which empirical science cannot). I have trouble with the "anything goes" pragmatism that vulgar empiricists display.
I mean geez, at that rate, you might as well lament all day about how the axioms are not EMPIRICALLY falsifiable! Philosophy provides the framework on which science can build bodies of knowledge -- ie. the skeleton that supports the musculature of science.
Rand's theory addressed that which was not addressable via strictly 3rd-person empirical methods.
This speaks to the problem that I have with Dennett. He has become guilty of his own notion of "greedy reductionism" in taking the 3rd-person view to be the objective view of consciousness. That is wrong. The 1st-person view is the objective view of consciousness (though it is the subjective view of all else). It's damn counter-intuitive, but correct nonetheless. Nagel and Searle are more "on the money" here.
------------------ Ed, there are few things that are more "armchair" than *Rand's* view of human cognition ... Her theories of cognition and concept formation - basically the same thing - are all the result of her introspection, with a bit of deduction ... ------------------
See above.
------------------ My hypothesis is that this is what forced her to "sit on the fence" regarding evolution - an uncomfortable place to be for an atheist intellectual! Because evolution meant that human cognition *had to come from somewhere*, and that somewhere had to be *close by* ie the animal kingdom. ------------------
Daniel, Rand was working with limited scientific knowledge regarding evolution. To be sure, an objective philosophy will, by definition, remain consonant with the empirical data (Rand just didn't have enough data back then).
For example, this issue is largely (if not completely) cleared up upon integration of some of the newest findings (from a New Scientist article on how the human brain evolved from animal brains). Marcus had quoted from the article (in the SOLO Science forum) on April 9. As I'm not sure that you have access to said forum, I re-quote the relevant excerpts (along with my responses) below:
--------------------------------- Excerpt 1: So why don't our close evolutionary relatives, chimps and other primates, have similar abilities? The answer, recent analysis seems to suggest, lies in the fact that while humans and chimps have many genes in common, the versions expressed in human brains are more active than those in chimps.
My Response 1: Marcus, this is perhaps the most highly-plausible account for the evolution of humans to which I've come across. Basically, the genes (for our Big Brains) were always there in primates--but have always been switched off, in all of the sub-human varieties of such.
Excerpt 2: What's more, the brains of newborn humans are far less developed than those of newborn chimps, which means that our neural networks are shaped over many years of development immersed in a linguistic environment.
My Response 2: Excellent point indicating the unique "plasticity" of human brains! This point also resonates quite well with the principles of Objectivism.
It also highlights the importance of development (a real-life "jungle boy"--artificially mentally retarded--may not ever conceptually "leave" the jungle!)
Excerpt 3: In a sense, language is the last word in biological evolution. That's because this particular evolutionary innovation allows those who possess it to move beyond the realms of the purely biological. With language, our ancestors were able to create their own environment - we now call it culture - and adapt to it without the need for genetic changes.
My Response 3: Rand would be smiling. ---------------------------------
Daniel, another indirect confirmation of the unique potentiality of H. sapiens, is the recent economical explanation for the abrupt extinction of the physically superior H. neanderthalensis -- we were better traders and environment re-makers (ie. mind over muscle).
