Four important revisions to my own definition of worldview were in order. First was a recognition that a worldview is not just a set of basic concepts but a fundamental orientation of the heart. Second was an explicit insistence that at the deepest root of a worldview is its commitment to and understanding of the “really real.” Third was a consideration of behavior in the determination of what one’s own or another’s worldview really is. Fourth was a broader understanding of how worldviews are grasped as story, not just as abstract propositions.
