We must make a distinction between two types of invisibility. In
the one, the object is invisible only because it cannot be seen
in normal circumstances (black fighter bombers able to deflect
the detecting beams). In the other, the object is intrincically
invisible (a god, a ghost, the prime number between 6 and 8,
etc...).
