Feingold's speech, which will take place at 8 p.m. in Memorial Hall, is sponsored by UNC Young Democrats and is free and open to the public.
His appearance was originally scheduled for Dec. 3. but was postponed because of a Senate vote on legislation designed to help the United States recover economically from the attacks.
In an interview with The Daily Tar Heel on Friday, Feingold said he will discuss many of the same issues he planned to talk about prior to the attacks. He said he will also focus on the lessons that can be learned from the attacks.
Feingold's appearance at UNC is part of a national speaking tour that includes the University of Michigan-Ann Arbor, University of Texas at Austin and the University of Iowa.
"I decided a few days after (Sept. 11) that it was even more important to do the tour," he said. "I wanted to be one of the people who would go right away and discuss (issues)."
Feingold said he plans to stress the importance of maintaining basic civil liberties in light of increased security measures designed to prevent future attacks.
"At the domestic level, we need to have the right balance of law enforcement powers instead of the need to focus on civil rights," he said.
Feingold was the only senator to vote against the USA PATRIOT Act, an anti-terrorism bill that passed the Senate 98-1 on Oct. 25.
He also said it is important that domestic issues return to the forefront of American politics.
