This is from a review of one of Murray’s books. I hope it answers your questions.
In his summing up Charles Murray insists that Western civilization has produced the most impressive record of human accomplishment. He uses the basic profound insight of Aristotle as his main premise. “Other things being equal human beings enjoy the exercise of their realized capacities (their innate or trained abilities), and this enjoyment increases the more the capacity is realized, or the greater its complexity.”
A sense of purpose animates western culture, in the believe that human talent and creativity have something that transcends somehow the corporate human body. And an atmosphere of general freedom and encouragement of individual effort beyond a collectivist or group ethic.
It answers NONE of them.
