It is wonderful that five thousand years have now elapsed since the creation of the world, and still it is undecided whether or not there has ever been an instance of the spirit of any person appearing after death. All argument is against it; but all belief is for it. – Samuel Johnson, quoted by James Boswell

The weathercocks on spires and housetops were mysterious with hints of stormy wind, and pointed, like so many ghostly fingers, out to dangerous seas, where fragments of great wrecks were drifting, perhaps, and helpless men were rocked upon them into a sleep as deep as the unfathomable waters. – Charles Dickens, Dealings with the Firm of Dombey and Son

But it is presumptuous to scrutinize too far into these matters: Ghosts have undoubtedly forms and customs peculiar to themselves. – Francis Grose, “Superstitions: A Ghost,” A Provincial Glossary, with a Collectio

A house is never still in darkness to those who listen intently; there is a whispering in distant chambers, an unearthly hand presses the snib of the window, the latch rises. Ghosts were created when the first man woke in the night. – J.M. Barrie, The Little Minister, 1891
