In observance of the 10th anniversary of the death of the Rev. Martin L. King Jr., WAMU-FM is broadcasting a series of his lectures on nonviolence. King was assasinated four months after these lectures were recorded for the Canadian Broadcasting Corp.

In the broadcasts, King's tone is concerned and mediative, rather than having the passionate, ringing style that usually marked his oratory. A lecture entitled "Theoretical Reflections on Nonviolence and Social Change" will be aired at 10:30 a.m. today.

At 4:30 p.m. today, the alienation of the youth of the 1960s is discussed in "Youth and Social Action."

"Alienation is not confined to our young people, but it is rampant among them," said King, discussing the motivations of the civil rights activists, hippies and Vietnam war protesters. "Yet it should be foreign to the young . . . It is a form of living death. It is the acid of despair that dissolves society."

The last of the lectures, schedule for tomorrow at 4:30 p.m., is "Peace and Nonviolence." It was delivered at King's church, Ebenezer Baptist Church in Atlanta, on Christmas Day 1967. He spoke of the interdependence and interrelation of all people, observing, as he often did, "We must all learn to live together as brothers or we will perish as fools."
