A religious man and the son of a minister, in his later life Millikan argued strongly for a complementary relationship between Christian faith and science. He dealt with this in his Terry Lectures at Yale in 1926–27, published as Evolution in Science and Religion. He was a Christian theist and proponent of theistic evolution. A more controversial belief of his was eugenics – he was one of the initial trustees of the Human Betterment Foundation and praised San Marino, California for being "the westernmost outpost of Nordic civilization ... [with] a population which is twice as Anglo-Saxon as that existing in New York, Chicago, or any of the great cities of this country." In 1936, Millikan advised the president of Duke University in the then- racial segregated southern United States against recruiting a female physicist and argued that it would be better to hire young men.
