A worldview is a collection of mental models that form a structure or framework with which the brain classifies and interprets incoming and existing input. It forms the basis for what and how we think and what we choose to believe or dismiss. R. C. Hörsch argues that the prevailing worldview—that humans are special on Earth and in the Universe—is comically prejudiced and hopelessly wrong. He suggests that humans exist not because of, but in spite of, their complex brains and that, far from being a masterpiece of the evolutionary process, the human brain might be an unfortunate mutation, a handicap to survival and a fundamentally unintelligent device poorly suited and unable to cope with modern requirements for complicated decision making and thought.
