This is Volume VI of six in a collection on Psychology and Religion. Originally published in 1955, Man and his relationships was the theme of the tenth Present Question Conference which was held at Lady Margaret Hall, Oxford in July 1954. This raised the question 'Can both Answer and Question be found by putting one fundamental problem in the centre, towards which, like the petals of a flower, each specialized field of human knowledge gives its contribution?' This work attempts to see more clearly that the fundamental human problem of modem society is in fact the integration of diversity of experience-the bridging of the gap between specialisms.
