奥巴马在非裔历史文化艺术馆落成典礼上的演讲
John Hope Franklin once said, “Good history is a good foundation for a better present and future.” The best history doesn’t just sit behind a glass case; it helps us to understand what’s outside the case. The best history helps us recognize the mistakes that we’ve made and the dark corners of the human spirit that we need to guard against.
