"As inviduals develop, they do seem to adopt certain answers to the fundamental questions of life. These answers are put together into a comprehensive system - a view of the world. At the same time, however, this view of the world becomes the way they view the world. It becomes the spectacles through which they look, the grid upon which they organize reality. This view affects the way they answer the fundamental questions of life, and so on. If we understand worldviews this way, we can see why they are so hard to change. They tend to become firmly entrenched because they constantly reinforce themselves through the self-sustaining feedback loop."
