TODAY I’VE BEEN READING a book entitled Personal Beauty and Racial Betterment. The book is very rare today. It was published in 1920, during that hopeful time when a strong and mostly-healthy America was awakening to the scientific truths about race and the infinite possibilities of racial progress. Knight Dunlap, the author, was a professor of experimental psychology at Johns Hopkins University in Baltimore, and a substantial portion of his book was delivered by him as a lecture at Randolph-Macon College, just down the road from me in Lynchburg, Virginia. Despite some faults, the book is insightful and inspiring.
