If the ghosts care to prove their existence as objective phenomena they
are unfortunate in always discovering themselves to inaccurate
observers, to say nothing of the bad luck of frightening them into fits.
That the seers of ghosts are inaccurate observers, and therefore
incredible witnesses, is clear from their own stories. Who ever heard of
a naked ghost? The apparition is always said to present himself (as he
certainly should) properly clothed, either "in his habit as he lived" or
in the apparel of the grave. Herein the witness must be at fault:
whatever power of apparition after dissolution may inhere in mortal
flesh and blood, we can hardly be expected to believe that cotton, silk,
wool and linen have the same mysterious gift. If textile fabrics had
that property they would sometimes manifest it independently, one would
think--would "materialize" visibly without a ghost inside, a greatly
simpler apparition than "the grin without the cat."
