Reading a book by Dr. Alice P Mathews (Preaching that Speaks to Women) and felt this quote was approprate and helpful (slightly adapted to make it readable without needed to read the whole chapter).
A Modern knower can be a liberal or a conservative but cannot be a radical because the systems that taught them controls what can or cannot be known. But some in modernity yearn for a personal way of knowing that goes beyond the systems they have been taught or the relationships and instituions in which they have worked. These people beging to move out of modernity and into post-modernity.
