That is what conservatism properly understood is about. That's why we need to protect our institutions and not presume out of the arrogance of our own intellects to remake society in one fell swoop. That is the villainy of the French, Russian, and Chinese Revolutions in this century. If we can really alter human nature, than the constant of The End of History equation has suddenly become a variable. I think he's probably right.
History is on the move again.
I don't think, however, it's just the biotech thing. The Pentagon has just conducted a monumental study on the divergent attitudes of civilian and military leaders. What they discovered was that American elite opinion and military opinion are very, very different. The study didn't survey enlisted men, but my guess is that they're even more conservative. Indeed, I think the military is increasingly perceived as a cultural sanctuary from the decadence of the larger society.
