No, this principle applies only to "facts"--things that anybody can
observe, in more or less the same way.  If you say, "Look!  A duck!"
and everybody else says "I don't see anything," what are you to believe?

If it feels like a bellyache, don't conclude that it's a bellyache.
There may be an inner meaning to deal with!  Appendicitis, gallstones,
trichinosis, you've been poisoned, Cthulhu is due any minute ...

This kind of argument always arises when technology develops new
capabilities.  Bell: "Listen!  My machine can talk!" Epiktistes: "No,
it can only reproduce the speech of somebody else." It's something
new--we must argue over what to call it.  Any name we give it will
be metaphorical, invoking an analogy with human behavior, or something
else.  The bottom line is that the thing is not a man; no amount of
simulation and dissimulation will change that.


	When people talk of Ghosts I don't mention the Apparition by which I
	am haunted, the Phantom that shadows me about the streets, the image
	or spectre, so familiar, so like myself, which lurks in the plate-
	glass of shop-windows, or leaps out of mirrors to waylay me.
