History of ghosts
Mind, body dualism

Body is physical, mind is spirit (natural or supernatural?)

Human spirit or soul, both of the living and the deceased

Spirits can influence behavior, survive death
What are ghosts made of?
Composed of a misty, airy, or subtle material

If not physical, can't be seen

How are movement and thought now understood
Muscles driven by energy of metabolism

Mind controlled by nerve cells, ion transport

Both mind and body cease to act at death
Problems with ghost composition
Animating sprit, soul of the dead - relic of dualism

If substance then a gas

Fluids take the shape of their containers, don't form shapes on their own
Why so we see ghosts?

Brain fills in missing details
How does info get from brain?
Voice, writing

Broadcast by mouth, hand

Received by eyes, ears

Languages must be learned

Doesn't get out through thought
No mechanism to broadcast

No mechanism to receive

Unconscious processes likely vary among individuals
Disembodied info
Voice - sound waves dissipate

Info can't be stored in space

Even if they could, no way to detect it

We experience emotions of the past, not the actual past

Useful experience, but no reason to take it too literally
Anecdotal evidence
Not reliable

Be especially wary of testimony from "believers"
No plausible way to physically construct a ghost

No way for voices or thoughts to pass into the future

Ghosts are good social entertainment
