Nothing, "pseudo-spiritual," about it at all. Human beings have language, culture, history, art, marriage, etc. These are not biological categories.
Are these so unique? According to the Drake Equation there are at least 10,000 other intelligent civilizations in this galaxy alone. I'm sure all of those civilizations have language, culture, history, art, marriage, ect...
Could you explain how these things are NOT biological? Especially since they are originated by a biologic organism.

If you're alive, you've probably already transcended biology: in a, "state of nature," (and we have no record at all of human beings' life in any such state), you'd probably be dead by now. I'd probably have died several years ago, of old age. There wouldn't be farms in the Imperial Valley out here in California....
If anything connects homo sapians to nature it is technology. The evolution of technology directly parallels the evolution of the human brain. There is nothing transcendant about technology. The universe is a large place, considering this, are our creations so unique?

However, you are collapsing categories together, and the Drake equation (as Sagan and Shklovskii pointed out, it's all in how you set the values) isn't going to help that. Nor do I see how, "the evolution of technology directly parallels the evolution of the human brain," except in the most trivial sense that the human brain evolved to a certain point, then we started using tools and fire. Correlation doesn't imply causation, and all that...
Unless you have data to back the assertion up... Take a look at the progression of morphologic characteristics stretching back to homo ergaster and you'll see that as soon as tools pop into the picture, brain size explodes. As social organization becomes more advanced, there is an even larger explosion. The step from technology to biology cannot be made in one giant leap. There are little steps that happen along the way. For instance, everytime we learn something, we build connections in the gray matter in our skulls. The more gray matter, the more connections, the more we can learn, the more complex our behavior becomes. Assumption, yes, but not blind.
The Drake equation is an estimation. There could be more and their could be less. With billions and billions of galaxies in our visible
universe alone, it doesn't matter much. My usage of it only illustrates the point that none of the things we do are not unique. Surely there is some bug eyed monster out there how just might have evolved a complex way of communication...like pheremone poetry...

And anyways, the human brain doesn't seem to have evolved much over the last twenty millenia--and our culture, technology, language, etc., all sure have.
Yes it has.
Homo Sapians is the species that arose about 60,000 years ago.
Homo Sapians Sapians is the species that evolved about 10,000 years ago. The sub-species taxon was added to reflect changes in brain volume. From then on not enough time has passed to see any more morphologic changes though. Changes inside the brain have been recorded, though. New connections can be observed in todays children that would not be seen in a scan our mine or your brain. As soon as the gray matter that exists in skulls reaches is maximum connection density then we will see another explosion in brain size.
How long will this take? I don't know. I would say that our current expansion of technology creates a short time table. For instance, in Newton's day it was possible to have a working knowledge that spanned the bredth of human understanding. These days, that goal would be impossible. How many of you out there know how to do Tensor Calculus?

What's the reason for making it all a matter of biology, anyway?
Biology, more then anything else, truly explains who we are. One of the reasons there is no coherent theory that ties social sciences together is because of the insertion of these pseudo-religious principals into their postulations. As long as people cling to this position that "we are more then what we are made of" nothing but confusion will follow. No one will ever be able to put their finger on the
more and agree on what they see. Where as we can see a strand of DNA and analyze it (and maybe argue for a while) and eventually see what it says about who we are.
Hopefully you'll join in on this discussion. I've appreciated your insight thus far...
