“The human problem?”

in Indonesia, Palestine, and Kashmir - has demonstrated convincingly that parties to the most severe conflict may be induced to abandon war as the method of settlement in favour of mediation and conciliation, at a merciful saving of untold lives and acute suffering. Unfortunately, there may yet be some in the world who have not learned that today war can settle nothing, that aggressive force can never be enough, nor will it be tolerated. If this should be so, the pitiless wrath of the organized world must fall upon those who would endanger the peace for selfish ends. For in this advanced day, there is no excuse, no justification, for nations resorting to force except to repel armed attack.
Some Reflections on Peace in Our Time (1950)

1963, American University speech
Context: Let us examine our attitude toward peace itself. Too many of us think it is impossible. Too many think it unreal. But that is a dangerous, defeatist belief. It leads to the conclusion that war is inevitable — that mankind is doomed — that we are gripped by forces we cannot control. We need not accept that view. Our problems are manmade — therefore, they can be solved by man. And man can be as big as he wants. No problem of human destiny is beyond human beings. Man's reason and spirit have often solved the seemingly unsolvable — and we believe they can do it again.

Context: Human problems are more psychological than materialistic. This is not only true of individual behaviour, but in mass action also. A suggestion from a leader sparks off a revolution. Material circumstances help mass action, but in themselves do not raise action. The conditions of untouchability and of poverty in India, especially at the time of famine in Bengal in 1945-46, when thousands of destitute died of sheer hunger in the streets of Calcutta City, are such as would provoke an immediate revolution. But the revolution does not come off in the Indian masses. The reason is clear. In India there are revolutionary circumstances, but there is no revolutionary consciousness among the people. If the revolutionary consciousness is present, people would revolt against any injustice on the slightest pretext. And consciousness is essentially psychological.

Context: It seems to me that the idea of a personal God is an anthropomorphic concept which I cannot take seriously. I feel also not able to imagine some will or goal outside the human sphere. My views are near to those of Spinoza: admiration for the beauty of and belief in the logical simplicity of the order and harmony which we can grasp humbly and only imperfectly. I believe that we have to content ourselves with our imperfect knowledge and understanding and treat values and moral obligations as a purely human problem—the most important of all human problems.
