Integrity, Integration—such words indicate the needs of our age. They are needs which now affect humanity as a whole. All mankind needs to be integrated into the unity which it potentially is. Failure to achieve this integration involves the danger of destruction of large parts of humanity. St Augustine's definition of peace still holds good. It is ‘the tranquillity of order'.

This problem of integration hinges on another problem of integration, the integration which involves the incarnation of the spiritual life in the material life. Disintegration is the disease of our time, the converse of that specialisation and expertise which to some extent cannot be avoided. Men tend to be divided up into those who try to solve humanity's problems on a spiritual level, who pray about them, and live a relatively secluded life, and on the other hand those men who try to work on a solely material level, who live a relatively active life, working in the social, political, economic and similar spheres.
