Many of Gobineau's ideas were incorporated into Wagner's later operas.[153] Cosima Wagner wrote to Gobineau in May 1881 to tell him: "My husband is quite at your service, always reading The Races when he is not at work with the staging."[154] Gobineau wrote back to say: "I assure you there is no Bayreuthian more faithful than I".[154] Wagner, while accepting Gobineau's basic ideas into his philosophy, rejected Gobineau's pessimism about the fate of the Aryans.[154] Instead, he created the concept of regeneration, where the Aryans would return to their former glory by embracing his theories of art and rejecting what he called the corrupting influence of the Jews.[154]
