"But the streaky slime in their heavens,
Brought together by narrowing perceptions,
Appear'd transparent air; for their eyes
Grew small like the eyes of a man"
W.Blake. The Book of Urizen.

Working in this medium is difficult. Our messages get lost or misunderstood or miscommunicated. Our messengers get lost or fail to understand the import of their task. Contact is lost, sometimes for years, and without us, you too become lost. Through no fault of your own. Through no fault of ours. This atmosphere is thick. Jellied Air. Veiled in dense clouds of pollution. The mesh of communication and anti-communication waves and signals frustrates us. There may come a time when any contact at all becomes impossible.
