This brought to mind a quote I saw once from A. E. Boycott, given in his
presidential address to the Royal Society of Medicine in 1928:
"Alive or dead is a stupid question, because it does not exhaust the possibilities.
Our general notion of the universe leads us to expect that we shall meet with
things that are not so alive as a sunflower, and not so dead as a brick."
(A.E. Boycott, "Transition from Live to Dead: The Nature of
Filterable Viruses," quoted in "Viral Infections of the Nervous
System" by Richard T. Johnson.
