Irving Babbitt (August 2, 1865 – July 15, 1933) was an American academic and literary critic, noted for his founding role in a movement that became known as the New Humanism, a significant influence on literary discussion and conservative thought in the period between 1910 to 1930. He was a cultural critic in the tradition of Matthew Arnold, and a consistent opponent of romanticism, as represented by the writings of Jean-Jacques Rousseau.
