This is intended to be a practical comparison between two approaches. Accordingly it would be as well to start with a few truisms that are shared between them. In the first place, people only discover themselves and the world through their relationships with other people and this relationship is primary. Perspectives on the world follow and are fashioned by these relationships. In view ©f this, theology may be said to be reflection on human experience specifically understood as directed towards God. Thus Schillebeeckx (1969:214) describes man, from a theological point of view, as ‘a free being who must define himself in and towards the world in dialogue with God’. This may be contrasted with the definition of one sort of sociology, ‘critical sociology’, described by Hansen (1976:3) as ‘an invitation to become an involved, critical explorer of human and societal possibilities’.

Unless the theologian is to consider for the most part his own experience (the source of much individualistic agonizing of an existentialist sort commonly characterized as bourgeois sociology) he must perforce draw on some systematic body of reflection on the human condition. Traditionally, this has been provided by philosophy, but in more recent times the social sciences have rather cornered the interaction business.
