“In this it serves as shock therapy for students who have grown up with the unexamined belief that modern science is the only true path to knowledge. They have been taught that the scientific method is of a different order from all other human systems of understanding. The claim is that science, and only science, provides a clear window on reality and has the ultimate capacity to answer every question about nature. These assertions are untenable. Modern Western civilisation’s representation of reality is limited like that of every other civilisation. The sciences are cultural constructions to help us get by in the world. “A scientific theory is just a mathematical model we make to describe our observations,” cautions Stephen Hawking. “It exists only in our minds.”(15) Science is a simplification of the universe, which in its unfathomable vastness is always threatening to overwhelm the limited capacity of the human organism to comprehend. “I suspect there could be life and intelligence out there in forms we can’t conceive,” observes Martin Rees, British Astronomer Royal. “It could be there are aspects of reality that are beyond the capacity of our brains.”
