Context: This concept of "national defense" cannot be deemed an end in itself, justifying any exercise of legislative power designed to promote such a goal. Implicit in the term "national defense" is the notion of defending those values and ideals which set this Nation apart. For almost two centuries, our country has taken singular pride in the democratic ideals enshrined in its Constitution, and the most cherished of those ideals have found expression in the First Amendment. It would indeed be ironic if, in the name of national defense, we would sanction the subversion of one of those liberties — the freedom of association — which make the defense of our nation worthwhile.

1990s, Nobel Prize acceptance speech (1993)
Context: Together, we join two distinguished South Africans, the late Chief Albert Lutuli and His Grace Archbishop Desmond Tutu, to whose seminal contributions to the peaceful struggle against the evil system of apartheid you paid well-deserved tribute by awarding them the Nobel Peace Prize. It will not be presumptuous of us if we also add, among our predecessors, the name of another outstanding Nobel Peace Prize winner, the late Rev Martin Luther King Jr. He, too, grappled with and died in the effort to make a contribution to the just solution of the same great issues of the day which we have had to face as South Africans. We speak here of the challenge of the dichotomies of war and peace, violence and non-violence, racism and human dignity, oppression and repression and liberty and human rights, poverty and freedom from want.
