In pursuance of the strategy of non-violence he became a member of the Moral Re-Armament movement after attending its conference in Caux , Switzerland in 1953 . To promote peace , he featured in two films ( one on him , called A Man For All People ) and another with leaders like Kwame Nkrumah , Nnamdi Azikiwe , Jomo Kenyatta and Manase Moerane . Following the Sharpeville massacre in 1961 , Nkomo was a mediator between the government and the victims . He was one of the leaders who discussed the political situation in South Africa with Dag Hammarskjöld who was Secretary General of the United Nations during his visit to this country in January 1961 . 14 August 1968 , Nkomo was invited to speak at the University of Cape Town 's Day of Affirmation of Academic and Human Freedom . His address , The Courage to Think followed in a series after that of Robert Kennedy 's Ripple of Hope speech in June 1966 . In his speech he said , " The idea of a common patriotism and nationalism was always recognised by all . It was only in recent times with the emergence of apartheid theoreticians that the country definitely deviated from the path of a common nationalism . " " Some of the youth are courageous enough to look at everything with a crucially critical mind , and there are those who follow the path of least resistance , that of merely accepting things from their forebears without questioning . If it does not appear to be the case in our country it has at any rate manifested itself in other parts of the world.A quick look at the recent events affecting the students in Berkeley , U.S.A , ; in Columbia , U.S.A. ; at the Sorbonne , Paris ; in Rome ; in Prague ; and elsewhere will clearly indicate that the youth as represented by the students have become impatient with systems where they are merely on the receiving end ; they are beginning to question things in a dynamic and revolutionary miner . They are coming to a realisation that the youth and the students especially constitute an important social factor in the promotion of social change
