"Why should being belong to things themselves, rather than the process of knowing things? Why should we equate being, truth, and reality? How can we assume that knowledge belongs to the soul rather than the body? Why does the spiritual, assuming it exists, have so much power over the physical when it comes to knowledge? Doesn’t the physical world have just as much to do with forming a person’s intellect as a supposed spiritual one does? Why should we assume that the universe is eternal and its laws unchanging?"
