Keyes, former U.S. ambassador to the United Nations, was at N.C. State as a participant in the university's annual Human Rights Week.
Keyes finished third after President George W. Bush and Sen. John McCain, R-Ariz., in most Republican primaries last spring.
He said individual human rights are often neglected in societies that center on the belief that "might makes right" -- referring to the historical practice of a handful of individuals controlling and dominating a mass majority of people.
Keyes said he was always baffled by this practice and wondered how a small minority could exert so much control over a large group.
"Why did the many not stand up to the few?"
Keyes said human tendency is to fall into the background when a group exerts control over them.
"Humans very often find ways to slip into the background, taking their liberty and dignity with them," he said. "This is not necessarily a positive thing."
Challenging the belief that "might makes right," Keyes added that justice should not be whatever the strongest element says it is.
"But if might doesn't determine the principles of justice, what does?" Keyes questioned the audience.
