For Lonergan, the notion of objectivity is to be considered on four different levels. Preliminarily, empirical objectivity is to be reached by one's actual apprehending of certain empirical objects and data presented to the subject as experienced sensibly. Secondly, normative objectivity is attained when one intelligently grasps the meaning of the object presented in conformity with right norms and correct logic. Thirdly, absolute objectivity is obtained when the knowing subject rationally makes affirmations concerning the object in accordance with reasonable reflections and sound judgments. The process culminates in principal objectivity which means that one's judgment is supported by a series of relevant, related and correct judgments arranged in a pattern so as to form a harmonious constellation.
