“From an evolutionary perspective, the human races are all very similar variations of the same gene pool. The question that looms over all the social sciences, unanswered and largely unaddressed, is how to explain the paradox that people as individuals are so similar yet human societies differ so conspicuously in their cultural and economic attainments.”

Context: I believe that under the surface all people are the same. […] people are all essentially the same. Similar hopes, similar dreams, similar strengths, similar weaknesses. But we're also all bound by history and culture and habits. And so conflicts arise, in part, because of some weaknesses in human nature. When we feel threatened, then we like to strike out against people who are not like us. When change is happening too quickly, and we try to hang on to those things that we think could give us a solid foundation. And sometimes the organizing principles are around issues like race, or religion. When there are times of scarcity, then people can turn on each other. And so I don't underestimate the very real challenges that we continue to face, and I don't think it is inevitable that the world comes together in a common culture and common understanding. But overall, I am hopeful. And the reason I'm hopeful is, if you look at the trajectory of history, humanity has slowly improved.
