A Corpse or a Ghost- I'd sooner be one or t'other, square and fair, than a Ghost in a Corpse, which is my feelins at present.

I expressed just now my mistrust of what is called Spiritualism — ... I owe it a trifle for a message said to come from Voltaire's Ghost. It was asked, Are you not now convinced of another world? and rapped out, There is no other world — Death is only an incident in Life.

For I never have seen, and never shall see, that the cessation of the evidence of existence is necessarily evidence of the cessation of existence.
