“Another war is always coming, Robert. They are never properly extinguished. What sparks war? The will to power, the backbone of human nature. The threat of violence, the fear of violence, or actual violence, is the instrument of this dreadful will… The nation state is merely human nature inflated to monstrous proportions. QED, nations are entities whose laws are written by violence. Thus it ever was, so ever shall it be.”

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.

This originated from the notes of the journalist W.T. Stead, quoted in full in Fisher of Kilverstone (1973), Ruddock F. Mackay, Clarendon Press, p. 223.
Context: The humanising of war? You might as well talk about the humanizing of Hell!...... The essence of war is violence! Moderation in war is imbecility!..... I am not for war, I am for peace! That is why I am for a supreme Navy....... The supremacy of the British Navy is the best security for peace in the world...... If you rub it in both at home and abroad that you are ready for instant war..... and intend to be first in and hit your enemy in the belly and kick him when he is down and boil your prisoners in oil (if you take any), and torture his women and children, then people will keep clear of you.
