Marshall didn't publicly discuss his religion. His theory was that people who can see don't walk around saying, "I'm seeing things" all day. They simply see the world. And so, with religion, it was simply there with him. This unwillingness to discuss religion caused him much trouble. Some people perceived it as arrogance. Some people saw it is as weakness and shirking. Some people saw it was outdated and ridiculous. Some saw it as a wasted chance to make converts.

The "etym" is the fundamental 'bit' in the Joycean world, just as the atom is in the physical world. For Joyce, TV's annihilating of the 'etym' is as significant as in the realm of culture as the potentiality of destroying the atom in the physical world. Since, however, neither etym nor atom disappears as a result of the contemporary challenge, the process is abnihilisation, not actually a destruction.
Any extension of man's sensory life such as the dog, or the motor car, imprints numerous clichés on any language, extending its range of probe. All media of communications are clichés serving to enlarge man's scope of action, his patterns of association and awareness. These media create environments that numb our powers of attention by sheer pervasiveness. The limits of our awareness of these forms does not limit their action upon our sensibilities. Just as the rim-spin of the planet arranges the components of high- and low-pressure areas, so the environments created by linguistic and other extensions of our powers are constantly creating new climates of thought and feeling. Since the resulting symbolic systems are numerous, they are in perpetual interplay, creating a kind of sound-light show on an ever-increasing scale.
