NEW BRUNSWICK, N.J.  When a fellow student at Rutgers University urged Didi Onejeme to try Philosophy 101 two years ago, Ms. Onejeme, who was a pre-med sophomore, dismissed it as “frou-frou.”

“People sitting under trees and talking about stupid stuff  I mean, who cares?” Ms. Onejeme recalled thinking at the time.

But Ms. Onejeme, now a senior applying to law school, ended up changing her major to philosophy, which she thinks has armed her with the skills to be successful. “My mother was like, what are you going to do with that?” said Ms. Onejeme, 22. “She wanted me to be a pharmacy major, but I persuaded her with my argumentative skills.”

Once scoffed at as a luxury major, philosophy is being embraced at Rutgers and other universities by a new generation of college students who are drawing modern-day lessons from the age-old discipline as they try to make sense of their world, from the morality of the war in Iraq to the latest political scandal. The economic downturn has done little, if anything, to dampen this enthusiasm among students, who say that what they learn in class can translate into practical skills and careers. On many campuses, debate over modern issues like war and technology is emphasized over the study of classic ancient texts.
