From recipient of the 2009 Irving Kristol award Charles Murray’s acceptance speech, challenging conservatives:
The European model can’t continue to work much longer. Europe’s catastrophically low birth rates and soaring immigration from cultures with alien values will see to that. So let me rephrase the question. If we could avoid Europe’s demographic problems, do we want the United States to be like Europe?
Tonight I will argue for the answer “no,” but not for economic reasons. The European model has indeed created sclerotic economies and it would be a bad idea to imitate them. But I want to focus on another problem.
Critics of the European model are about to get a lot of new firepower. Not only is the European model inimical to human flourishing, twenty-first-century science is going to explain why. We who think that the Founders were right about the relationship of government to human happiness will have an opening over the course of the next few decades to make our case.
The reason is a tidal change in our scientific understanding of what makes human beings tick. It will spill over into every crevice of political and cultural life. Harvard’s Edward O. Wilson anticipated what is to come in a book entitled Consilience. As the twenty-first century progresses, he argued, the social sciences are increasingly going to be shaped by the findings of biology; specifically, the findings of the neuroscientists and the geneticists.
What are they finding?
Emphasis mine. Read the whole thing. You’ll be glad you did.
