This paper advocates the view that there is a permanent interpenetration between the cultural constituents of human mental activity; and that, despite the unity of the mind, these constituents are not necessarily coherent for they are in permanent transformation. Indeed, mental activity gives birth to multiple competing and conflicting interpretations of events and attitudes; and, in every part of this activity, there is the intervention of belief. Science does not possess firm grounds to control faith, for its constructs change with time. Moreover, faith also manifests itself in different beliefs and no belief may be proven to be more fully and absolutely reliable than any other. Hence, all of the different beliefs can offer only partial images of divinity, owing to the diversity of cultures and historical conditions, but not a complete representation. It follows from this that the reasonable attitude consists in letting everyone experience faith in the way that he or she conceives it and in encouraging reflection and communication among the holders of competing world-views.
