" The reliability of stools? Solids, liquids, gases, the dance of atoms, the bounce and race of molecules, ethers, electrical charges. The eyes and habits of illusion. Retinal images, bogus images, traveling to the brain. The pupils trying to tell the truth to the inner eye. The eye of the heart. The eye of the head. The eye of the mind. All seeing differently. "
