Development of doctrine and differentiation of consciousness

"The possibility of a development in doctrine arises whenever there occurs a new differentiation of consciousness, for with every differentiation of consciousness the same object becomes apprehended in a different and a more adequate fashion." (Lonergan, [PGT] CWL 17:210) 

Community as primordial

"The traditional view was the product of trinitarian and christological problems as these were conceived within the systematic differentiation of consciousness as originated by Aristotle and transposed to Christian soil by Thomas Aquinas. The contemporary view comes out of genetic biology and psychology. From the 'we' of the parents comes the symbiosis of mother and child. From the 'we' of the parents and the symbiosis of mother and child comes the 'we' of the family. Within the 'we' of the family emerges the 'I' of the child. In other words the person is not the primordial fact. What is primordial is community. It is within the community, and through the intersubjective relations that are the life of community, that there arises the differentiation of the individual person." (Lonergan, [PGT] CWL 17:210-211)
