Previous economic downturns have often led to decreased enrollment in the disciplines loosely grouped under the term “humanities” — which generally include languages, literature, the arts, history, cultural studies, philosophy and religion. Many in the field worry that in this current crisis those areas will be hit hardest.

Already scholars point to troubling signs. A December survey of 200 higher education institutions by The Chronicle of Higher Education and Moody’s Investors Services found that 5 percent have imposed a total hiring freeze, and an additional 43 percent have imposed a partial freeze.

In the last three months at least two dozen colleges have canceled or postponed faculty searches in religion and philosophy, according to a job postings page on Wikihost.org. The Modern Language Association’s end-of-the-year job listings in English, literature and foreign languages dropped 21 percent for 2008-09 from the previous year, the biggest decline in 34 years.

“Although people in humanities have always lamented the state of the field, they have never felt quite as much of a panic that their field is becoming irrelevant,” said Andrew Delbanco, the director of American studies at Columbia University.
