  The fragmentation of philosophy and its consequent separation from theology is, according to Rosmini, a necessary consequence of sensationalist thinking. There can be no place for revealed doctrine to be expounded as true science unless certain truths are already demonstrated, in the logical order at least, by philosophical reason. On the other hand, theology itself often cannot make progress unless it is prepared to turn to philosophy for assistance. The notions of body, of person and of many other matters essential to theology, cannot be adequately expressed in isolation from philosophical teaching. In its turn, according to Rosmini, divine revelation does not cancel, but completes and ennobles reason, especially by drawing its attention to problems such as the relationship between person and nature which would otherwise escape its attention.
