At some public universities, where funding is eroding, humanities are being pared. In September, for example, Edinboro University of Pennsylvania announced that it was closing its sparsely populated degree programs in German, philosophy, and world languages and culture.

At elite universities, such departments are safe but wary. Harvard had a 20 percent decline in humanities majors over the last decade, a recent report found, and most students who say they intend to major in humanities end up in other fields. So the university is looking to reshape its first-year humanities courses to sustain student interest.

Princeton, in an effort to recruit more humanities students, offers a program for high school students with a strong demonstrated interest in humanities — an idea Stanford, too, adopted last year.

“Both inside the humanities and outside, people feel that the intellectual firepower in the universities is in the sciences, that the important issues that people of all sorts care about, like inequality and climate change, are being addressed not in the English departments,” said Andrew Delbanco, a Columbia University professor who writes about higher education.
