Dear Prof Smullyan,
I hope this letter finds you in good health.
I just realized that today using "brain fingerprinting" the
following exchange (like the one in your "An Epistemological
Nightmare") is entirely possible where its validity would be
supported by many respected scientists.
It is the Year 2000. Frank is in a laboratory in
the home of an experimental epistemologist.
The doctor holds up a photograph of a woman and asks,
"Do you recognize this person?"
Frank: Yes, I do.
Epistemologist: Wrong!
Frank: What!!? I'm just saying that she _seems_
familiar to me.
Epistemologist: Again you are wrong.

i had a few reactions:
1. advances such as these will chip away at mind-body dualism
slowly but surely.
2. the PBS show (mentioned below) had two similar segments:
Eldelman uses a huge brain-reading machine, and
the segment on dectecting false memory.
3. i thought "brain fingerprinting" is a misnomer, because
it works like a lie-detector (polygraph).
a true "brain fingerprinting" would work by matching
remnants of brain activity left at the crime scene
with the suspect's unique brain activity patterns.
fin-ger-print \-,print\ n (1859)
1: the impression of a fingertip on any surface; esp:
an ink impression of the lines upon the
fingertip taken for purpose of identification
2: chromatographic, electrophoretic, or spectrographic
evidence of the presence or identity of a
substance; esp :the chromatogram or
electrophoretogram obtained by cleaving a
protein by enzymatic action and subjecting
the resulting collection of peptides to
two-dimensional chromatography or electrophoresis

Edelman on consciousness
i learned about Edelman's work recently from a PBS show hosted
by Alan Alda. it seems that a good book came out in March.
URL: http://www.krasnow.gmu.edu/ascoli/universe.html
Abstract: This essay is a commentary on Edelman and Tononi's
A Universe of Consciousness How Matter Becomes Imagination,
a scientific book on the mind-body relationship. [...]
In A Universe of Consciousness (Basic Books, NY, 2000),
Gerald Edelman and Giulio Tononi face the mind-body problem
straight up, guiding the readers hand-by-hand through a
fascinating and exciting journey of 222 intense pages.
