In Scott Adams' "God's Debris," he explores the idea that practicality shapes how we see the world. Our brains, small in size, must manage the overwhelming amount of information and illusions we encounter daily. This process helps us filter out what is necessary for survival and understanding.

As a result, our perceptions are not fixed but rather adaptable. They shift as we seek comfort in familiar beliefs, allowing us to create a sense of safety amidst the chaos of reality. The author suggests that we continuously mold our views until we find a protective and comforting narrative, even if it is a delusion.
