Anti-evolution activism: 1918–1925[edit]
Before World War I, Bryan believed moral progress could achieve equality at home and, in the international field, peace between all the world's nations.[49][50]

Bryan opposed the theory of evolution for two reasons. First, he believed that what he considered a materialistic account of the descent of man through evolution undermined the Bible. Second, he saw Darwinism applied to society as a great evil force in the world promoting hatred and conflicts, especially the World War.[51]

In his famous Chautauqua lecture, "The Prince of Peace," (1909) Bryan warned that the theory of evolution could undermine the foundations of morality. He concluded, "while I do not accept the Darwinian theory I shall not quarrel with you about it," and, evoking, the design argument, he said "I have a right to assume, and I prefer to assume, a Designer back of the design— a Creator back of the creation."[52]
