A few thoughts on OpenBSD 5.8

I've been using OpenBSD since way back at release 2.3 in 1998, so I've gone through upgrades that took a fair amount of work due to incompatible changes, like the switch from ipf to pf for host firewalling or the change to ELF binaries. The upgrade from 5.7 to 5.8 was a pretty smooth and easy one, for the most part. The two most painful changes for me were the replacement of sudo with doas and the dropping of support in the rc.conf for the pf_rules variable.  While sudo is still available as a package, I like the idea of reducing attack surface with a simpler program, so I made the switch. The two things I miss most about sudo are the ability to authenticate for a period of time and the ability to have a single config file across a whole set of servers. The former I'm just living with, the latter I've adjusted to by having a single config file that has lines commented out depending on which server it's on. I did have one moment of concern about the quality of doas when it incorrectly reported the line number on which I had a syntax error in the config file--fortunately, this was just a failure to increment the line count on continuation lines (ending with a "\") which is fixed in the -current release.

The removal of the pf_rules variable support from rc.conf was a bigger issue--I used to just put the default pf.conf rules file in place with each release and upgrade, and keep my changes in a pf.conf.local file that was specified in the pf_rules variable. The effect was that from the period after the upgrade until I noticed the change, my systems were using the default rules and thus more exposed than they were supposed to be. This wasn't the first time an incompatible change decreased my level of security--the removal of tcpwrappers support from SSH was another. I used to use a combination of pf rules and hosts.allow as additional layers of protection on my SSH access, and had a set of tools that allowed me to easily add IP addresses to or remove them from my hosts.allow files. This would have been a layer of defense still in place with the loss of my pf rules, had it still been in existence. Fortunately, I also have SSH on a non-standard port and only allow SSH key logins, not user/password logins, and most of my systems can't be reached on any port without first making a VPN connection, which requires two-factor authentication.

A minor annoying change that was made in 5.8 was putting the file /var/unbound/db/root.key into /etc/changelist, so that the file gets checked daily by the security script. The issue with this is that if you are actually using unbound with DNSSEC, this file changes daily, though only in the comments. My "reportnew" log monitoring tool has a feature that allows you to be notified if files that are expected to change on some periodic schedule do not change, and that would be more appropriate than getting daily notifications that yes, the autotrust anchor file has been updated yet again. But what would really be ideal here would be a check that the non-comment components have not changed. (Others have also complained about this.)

A final issue I've run into with OpenBSD 5.8 is not a new issue, but it's one that still hasn't been fixed with pf. That is that pf logs certain traffic (IGMP in particular) when it matches a rule that does not call for logging. This appears to be the same issue that was fixed earlier this year in pfsense, which is derived from an older fork of pf.

Al Seckel exposed

"I believe that we are rapidly transitioning from an Age of Information to an Age of Misinformation, and in many cases, outright disinformation." -- Al Seckel, in an interview published on Jeffrey Epstein's website, "Jeffrey Epstein Talks Perception with Al Seckel"

Mark Oppenheimer's long-awaited exposé on Al Seckel, "The Illusionist," has now been published and I urge all skeptics to read it. Seckel, the former head of the Southern California Skeptics and a CSICOP Scientific and Technical Consultant who was listed as a "physicist" in every issue of the Skeptical Inquirer from vol. 11, no. 2 (Winter 1987-88) to vol. 15, no. 2 (Winter 1991) despite having no degree in physics, has long been known among skeptical insiders as a person who was misrepresenting himself and taking advantage of others. Most have remained silent over fear of litigation, which Seckel has engaged in successfully in the past.

An example of a legal threat from Seckel is this email he sent to me on May 27, 2014:
Dear Jim,
News has once again reached me that you are acting as Tom McIver's proxy in
spreading misinformation and disinformation about me. Please be aware that
I sued McIver in a Court of Law for Defamation and Slander, and after a
very lengthy discovery process, which involved showing that he fabricated
letters from my old professors (who provided notarized statements that they
did not ever state nor write the letters that McIver circulated, and the
various treasures who were in control of the financial books of the
skeptics, also came forth and testified that no money was taken, and McIver
was unable to prove any of his allegations. The presiding Judge stated that
this was the "worst case of slander and defamation" that he had ever seen.
Nevertheless, even with such a Court Order he is persisting, and using (and
I mean the term "using") you to further propagate erroneous misinformation.
Lately, he has been making his defamatory comments again various people,
and posting links to a news release article by the Courthouse News (a press
release service) that reports the allegations set forth in complaints. Just
because something is "alleged" does not mean it is True. It has to be
proven in a Court of Law. In this case, after a lengthy discovery process
(and I keep excellent records) the opposite of what was alleged was
discovered, and the opposing counsel "amicably" dismissed their charges
against me. The case was officially dismissed. In fact, the opposing
counsel has been active in trying to get the Courthouse News to actively
remove the entire article, and not just add a footnote at the end.
I note that you have been trying to add this link to my wikipedia page. I
have never met you, and am not interested in fighting with you. I am
attaching the official Court document that this case was filed for
dismissal by the opposing counsel. You can verify yourself that this is an
accurate document with the Court. So, once again, McIver has used you.
My attorneys are now preparing a Criminal Complaint against McIver for so
openly violating the Court Order (it is now a criminal offense), and will
once again open the floodgates of a slander and defamation lawsuit against
him and his family, and anyone else, who aids him willing in this process.
This time he will not have his insurance company cover his defense. This
time that axe will come down hard on him.
For now, I will just think you are victim, but please remove any and all
references to me on any of your websites, and that will be the end of it.
You don't want to be caught in the crossfire.
Yours sincerely,
Al Seckel
--
Al Seckel
Cognitive neuroscientist, author, speaker
Contrary to what Seckel writes, we have, in fact, met--I believe it was during the CSICOP conference, April 3-4, 1987, in Pasadena, California.  I am not an agent of Tom McIver, the anthropologist, librarian, and author of the wonderful reference book cataloging anti-evolution materials, Anti-Evolution, who Seckel sued for defamation in 2007, in a case that was settled out of court (see Oppenheimer's article). I have never met Tom McIver, though I hope I will be able to do so someday--he seems to me to be a man of good character, integrity, and honesty.

The news release Seckel mentions is regarding a lawsuit filed by Ensign Consulting Ltd. in 2011 against Seckel charging him with fraud, which is summarized online on the Courthouse News Service website. I wrote a brief account of the case based on that news article on Seckel's Wikipedia page in an edit on March 13, 2011, but it was deleted by another editor in less than an hour.  Seckel is correct that just because something is alleged does not mean that it is true; my summary was clear that these were accusations made in a legal filing.

Seckel and his wife, Isabel Maxwell (daughter of the deceased British-Czech media mogul, Robert Maxwell), rather than fighting the suit or showing up for depositions, filed for bankruptcy.  Ensign filed a motion in their bankruptcy case on December 2, 2011, repeating the fraud allegations.  But as Seckel notes, Ensign did dismiss their case in 2014 prior to his sending me the above email.

So why should anyone care?  Who is Al Seckel, and what was he worried that I might be saying about him? This is mostly answered by the Oppenheimer article, but there is quite a bit more that could be said, and more than what I will say here to complement "The Illusionist."

Al Seckel was the founder and executive director of the Southern California Skeptics, a Los Angeles area skeptics group that met at Caltech.  This was one of the earliest local skeptical groups, with a large membership and prominent scientists on its advisory board.  Seckel has published numerous works including editing two collections of Bertrand Russell's writings for Prometheus Books (both reviewed negatively in the Journal of Bertrand Russell Studies, see here and here).  He has given a TED talk on optical illusions and authored a book with the interesting title, Masters of Deception, which has a forward by Douglas R. Hofstadter.  Seckel was an undergraduate at Cornell University, and developed an association with a couple of cognitive psychology labs at Caltech--in 1998 the New York Times referred to him as a "research associate at the Shimojo Psychophysics Laboratory." His author bios have described him as author of the monthly Neuroquest column at Discover magazine ("About the Author" on Masters of Deception; Seckel has never written that column), as "a physicist and molecular biologist" (first page of Seckel's contribution, "A New Age of Obfuscation and Manipulation" in Robert Basil, editor, Not Necessarily the New Age, 1988, Prometheus Books, pp. 386-395; Seckel is neither a physicist nor a molecular biologist), and, in his TED talk bio, as having left Caltech to continue his work "in spatial imagery with psychology researchers as Harvard" (see Oppenheimer's exchanges with Kosslyn, who has never met or spoken with him and Ganis, who says he has exchanged email with him but not worked with him).

At Cornell, Seckel associated with L. Pearce Williams, a professor of history of science, who had interesting things to say when McIver asked him about their relationship. While in at least one conference bio, Seckel is listed as having been Carl Sagan's teaching assistant, I do not believe that was the case. The Cornell registrar reported in 1991 in response to a query from Pat Linse that Seckel only attended for two semesters and a summer session, though a few places on the web list him as a Cornell alumnus.

Seckel used to hang out at Caltech with Richard Feynman. As the late Helen Tuck, Feyman's administrative assistant, wrote in 1991, Seckel "latched on to Feynman like a leach [sic]." Tuck wrote that she became suspicious of Seckel, and contacted Cornell to find that he did not have a degree from that institution. You can see her full letter, written in response to a query from Tom McIver, here.

As the head of the Southern California Skeptics, Seckel managed to get a column in the Los Angeles Times, titled "Skeptical Eye." Most of his columns were at least partially plagiarized from the work of others, including his column on Sunny the counting dalmation (plagiarized from Robert Sheaffer), his column on tabloid psychics' predictions for 1987 (also plagiarized from Sheaffer), and his column about Martin Reiser's tests of psychic detectives (plagiarized directly from Reiser's work). When Seckel plagiarized Sheaffer, it was brought to the attention of Kent Harker, editor of the Bay Area Skeptics Information Sheet (BASIS), who contacted Seckel about it. Seckel apparently told Harker that Sheaffer had given his permission to allow publication of his work under Seckel's name, which Sheaffer denied when Harker asked. This led to Harker writing to Seckel in 1988 to tell him about Sheaffer's denial, and inform him that he, Seckel, was no longer welcome to reprint any material from BASIS in LASER, the Southern California Skeptics' newsletter. While most skeptical groups gave each other blanket permission to reprint each others' material with attribution, Harker explicitly retracted this permission for Seckel.

This is, I think, a good case study in how the problem of "affiliate fraud"--being taken in by deception by a member of a group you self-identify with--can be possible for skeptics, scientists, and other educated people, just as it is for the more commonly publicized cases of affiliate fraud within religious organizations.

This just scratches the surface of the Seckel story. I hope that those who have been fearful of litigation from Seckel will realize that, given the Oppenheimer story, now is an opportune time for multiple people to come forward and offer each other mutual support that was unhappily unavailable for Tom McIver eight years ago.

(BTW, one apparent error in the Oppenheimer piece--I am unaware of Richard Feynman lending his name for use by a skeptical group. He was never, for example, a CSICOP Fellow, though I'm sure they asked him just as they asked Murray Gell-Mann, who has been listed as a CSICOP Fellow since Skeptical Inquirer vol. 9, no. 3, Spring 1985.)

"Oh, like everyone else, I used to parrot, and on occasion, still do." -- Al Seckel (interview with Jeffrey Epstein)

Corrected 22 July 2015--original mistakenly said Maxwell was Australian.

Update 22 September 2015--an obituary has been published for Al Seckel, stating that he died in France on an unspecified date earlier this year, but there are as yet no online French death records nor French news stories reporting his death. The obituary largely mirrors content put up on alseckel.net, a domain that was registered on September 18 by a user using Perfect Privacy LLC (domaindiscreet.com) to hide their information. (That in itself is not suspicious, it is generally a good practice for individuals who own domain names to protect their privacy with such mechanisms and I do it myself.)

Update 24 September 2015: French police, via the U.S. consulate, confirmed the death of Al Seckel on July 1, 2015. His body was found at the bottom of a cliff in the village of Saint-Cirq-Lapopie.

Update 21 December 2015: A timeline of Al Seckel's activities may be found here.

Update 14 April 2022: Al Seckel's death has been declared a suicide.

Summary of 1994 CSICOP conference

I just stumbled across an old Usenet post of mine which summarizes a small part of the CSICOP conference held in Seattle June 23-26, 1994 (PDF of conference program; PDF of conference announcement mailing) with Robert Sheaffer's reply. I don't recall if I wrote the further followups, and didn't find any in a brief search. My 1992 Dallas CSICOP conference summary and a number of others may be found at the Index of Conference Summaries on this blog.

>I'm surprised that so little has been written about the recent conference on 
>this group. Please, any who attended, tell all!

I had intended to write up a summary of the Seattle conference similar
to the one I did for the 1992 Dallas conference (which may be found
in /pub/anson/Arizona_Skeptic on netcom.com, in vol. 6 somewhere, over
two issues).  Events conspired against me, however.  My flight did
not arrive until the conference had already begun on Thursday night,
and I was quite disappointed to miss Robert Baker's presentation in the
session on alien abductions.  I also brought only an old school notebook,
which I found contained only two blank sheets of paper in it.  Then I
planned to view Becky Long's videotapes of the sessions afterward, but
her camera's battery recharger broke.  So the following is all from memory.

I arrived at the conference on Thursday evening and was surprised to
find that the main conference room was completely full and an overflow
crowd was watching via closed-circuit television.  This was the largest
CSICOP conference to date.  I believe that for the alien abduction and
False Memory Syndrome-related sessions there were over 700 attendees.
(I seem to remember somebody telling me that, but we know how unreliable
human memory is.)
   I showed up in the middle of a presentation by Thomas Bullard, who was
very impressed by what he claimed were amazing consistencies between
the accounts of abductees.  He argued against the claim (made by Baker?)
that the motifs in abduction stories can be traced to "Close Encounters
of the Third Kind" by pointing out the same motifs in earlier abduction
claims.  (Yeah, but what about earlier appearances of "Grey"-like aliens in
other science fiction?)
   Next, John Mack spoke about why he was speaking at a CSICOP conference
and discussed the "intense polarization in ufology" between skeptics and
believers.  He said that he was a skeptic about UFO abductions and that
he considers it to be an unsolved mystery.  At times he sounded like
John Keel or Jacques Vallee--suggesting that aliens are interdimensional
creatures that can't be reduced to any known categories of human thought.
Like Bullard, he appealed to the consistency between testimonies.
I wrote down a series of questions he had for CSICOP and skeptics:

   1. Why so much vehemence in these attacks? [on him, on abduction claims]
   2. Why so much certainty?
   3. Why do we attack the experiencers themselves?
   4. Why do you attack writers of your own commissioned reports who
      don't come up with the conclusions you want?

I have no idea what the last question is supposed to be referring to,
since CSICOP does not commission research.  It sounds like a question
more appropriately addressed to MUFON regarding its treatment of
investigators of the Gulf Breeze UFO sightings.

   Since Nicholas Spanos died tragically in an airplane crash just a
week or so before the conference, at the last minute clinical psychologist
William Cone from Newport Beach, Calif. was brought in.  (He was already
a conference attendee.)  He began by saying that he didn't bring any
slides, but if the whole audience would just look at the screen, research
shows that about 2% of us would see things on it anyway.  Cone said that
he has worked with a few dozen abductees, including some in locked wards
of mental institutions.  He argued that abduction research that he has seen
is very badly done, with the researchers imposing their views on their
subjects.  He offered a number of possible answers to the question "Why
would anyone make up stories like this?":  (1) for the money (he gave
a specific example from his own experience), (2) for notoriety and
attention (he said that he's had abductees tell him they had never told anyone
about their experience before, and then show up on a tabloid TV show a
week later), (3) for identity with a group of people.
   He seemed to rebut most of the claims made by Bullard and Mack about
abductees.

   Also added to the program was abductee and hypnotherapist Sharon
Phillip (?), who was brought in by Mack.  She described her own
UFO sighting/abduction and promoted the usefulness of hypnotherapy.

   Also present was Donna Bassett, who passed herself off as an abductee
in Mack's group and then went public in the _Time_ magazine article
about Mack.  She stated that, just as women have been doing for
centuries, she faked it.  She had very strong words of criticism for
Mack's methodology and claimed that his clients are telling Mack what
he wants to hear, but say other things behind his back.  She accused him
of not getting informed consent from his clients about what they are
getting into.

   Mack replied by saying that he could not discuss her case because
of confidentiality, but that he was not convinced that she *wasn't*
really an abductee.  (He implied that he had reasons for thinking
this that he was not at liberty to discuss.)  He flat out denied
parts of her story, such as the part about his breaking her bed
while sitting on it from his enthusiastic reaction to her story about
being on a UFO with JFK and Kruschev.  He also suggested that Phil
Klass had put her up to her hoax, since her husband had worked with
Klass at _Aviation Week_.  This prompted the biggest outburst of
anger that I witnessed at the conference, from Klass, who stated that
he had not seen the Bassetts for many years and heard about the hoax
in the media like everybody else.  He subsequently contacted them,
and was responsible for Donna Bassett's being invited to the CSICOP
conference.

   There followed a series of audience questions and answers, including
several which expressed concern about Bassett being brought into the
conference without Mack's knowledge.  Some of these concerned audience
members changed their minds when told that Mack was already well aware
of the specifics of Donna Bassett's charges as a result of the _Time_
story.

Well, that was Thursday, June 23.  I'll comment further later about
the two Friday sessions and Carl Sagan's keynote address,
the three Saturday sessions and the luncheon talk about CSICOP and
the Law, and the Sunday session--or perhaps others can jump in.

I was going to comment about this at the conference, were it not such a
mob scene that getting to a microphone became nearly impossible:

Bullard was right to object to Baker's statement that 'all these grey
aliens come from the 1977 movie CEIIIK'. (Bullard went on to cite some
pre-1977 examples).

However, Marty Kottmeyer makes a pretty good case tracing the origin of the
_genre_ to Barney Hill who in March 1964 (date from memory: beware FMS)
sketched an alien that had supposedly abducted him. This drawing was
subsequently widely published. Marty found out, however, that an episode
of _The Twilight Zone_ had aired with a nearly-identical alien, just
A FEW DAYS before Barney made his sketch. (The individual sessions with
Dr. Benjamin Simon were all carefully dated and transcribed, and fan
books tell when each _Twilight Zone_ episode first aired.)

Spam email from Christine Jones for governor campaign

I received the following spam email today (a link on the email claims, falsely, that I opted in for it in October 2013) from the Christine Jones for governor campaign.  Jones is a former GoDaddy executive who looks like a terrible candidate for governor of Arizona.

Dear James,

        As a Republican candidate for Governor, I am frequently
asked where I stand on the issues important to our state-issues
ranging from immigration and education to economic development
and healthcare.

        At a recent forum I was asked one of the single-most
important questions that a candidate for political office can
face. The question was, "Where does your moral compass come
from?"
        At three years old, I climbed onto the Sunday School bus
that drove the neighborhood kids to the local evangelical church.

It was there that I learned about God and His Son, Jesus. Since
then, I have let my personal relationship with Him be my moral
compass.
        One of my life phrases is, "Do the right thing because
it's the right thing to do." I am not interested in making
excuses or politicizing important issues. I am interested in
doing things based on conviction and personal belief. As
Governor, I can promise you that I will adhere to my moral
compass.
        If you would like to hear more about my story and why I
am running for Governor, I invite you to join me Tuesday, April
29th, from 6:30-8:00pm at New Life Community Church of the
Nazarene in Show Low. I hope you can make it!

        Best,

How to use Google Authenticator with OpenBSD, OpenSSH, and OpenVPN--and why you might not want to

I thought that Google Authenticator might be a quick and easy two-factor authentication solution for VPN access to my personal network, so I did some Google searches to see if that were so.  I found quite a few sources describing how to set it up with systems that use Linux Pluggable Authentication Modules (PAM), but very little about using it with BSD Authentication on OpenBSD.

The most promising link I came across was to an implementation of Google Authentication for OpenBSD that was last updated in early 2013, based on Google's PAM code, but I couldn't get it to work.  It compiled and installed, and the googleauth code for generating a secret (and a very insecure way of generating a QR code to use to import it into the Google Authenticator application) worked fine, but I couldn't successfully use it for console login, OpenSSH login, or OpenVPN login.

I also found the standard OpenBSD port for openvpn_bsdauth, which compiled, installed, and worked successfully for password authentication by adding these lines to my OpenVPN configuration:
script-security 2
tmp-dir <path to dir writable only by _openvpn user>
auth-user-pass-verify /usr/local/libexec/openvpn_bsdauth via-file

This also requires that the authenticating user be put into the _openvpnusers group.

I was unable to get the via-env method to work, however.

I next tried the standard OpenBSD port of login_oath, which implements the OATH toolkit, which uses the same time-based TOTP protocol that Google Authenticator uses.  This turned out to do the trick.  Once installed, you create a secret key that the server authentication will check against and store it in your home directory (one thing I liked about googleauth is that it stores the shared secret in a system directory to which the user doesn't have access; better still is the suggestion of keeping the secrets on an auth server as totp-cgi does).  The documentation recommends creating the secret (which the user doesn't need to know except for the initial configuration of the Google Authenticator client application) by doing:
openssl rand -hex 20 > ~/.totp-key
I then needed to convert this from hex to base32, which is simple enough to do with the method the documentation recommends, which is using the perl module Convert::Base32 (OpenBSD port p5-Convert-Base32) and a short script like:
#!/usr/bin/perl
use Convert::Base32;
open (FILE, "/home/vpnuser/.totp-key");
$secret = <FILE>;
close (FILE);
$code = pack ('H*', $secret);
print encode_base32($code)."\n";
The resulting code can be manually entered into Google Authenticator.

To use Google Authenticator as a login method, I updated the login class for the user I wanted to use in /etc/login.conf so that its last two lines were:
:auth=-totp,passwd:\
:tc=default:
This allows either Google Authenticator or password authentication at the console, but only Google Authenticator via OpenSSH or OpenVPN as I configured them.  Instead of using "-totp" you can also use "-totp-and-pwd" which requires the entry of both your Google Authenticator code and your password (in that order, with a slash in between them) in order to authenticate.

For OpenSSH, I added the following lines to my sshd_config:
Match User <vpnuser>
     PasswordAuthentication yes
     AuthenticationMethods publickey,password:bsdauth
I don't allow password authentication at all for other users; for this user, an SSH public key must first be used, then Google Authenticator must also be used before a successful login. [Updated 1 Nov 2013 to add:  After a reboot, this ssh config failed with a log message of "fatal: auth2_update_methods_lists: method not in AuthenticationMethods".  Removing the ":bsdauth" made it work again (it works since the "password" authentication method will use BSD Authentication by default), but this looks like an SSH bug.]

So why might you not want to do this?  While Google Authenticator ensures that what is used over the network as a password is better than a typical user-selected password, it effectively stores a shared secret in plaintext at both ends of the connection, which is far less secure than SSH public key authentication.  If the device where Google Authenticator is present gets compromised, that secret is compromised.  And as the above link about totp-cgi points out, if you use Google Authenticator with the same secret across multiple machines, that secret is only as secure as the least secure host it's stored on, and using different secrets for different machines doesn't scale very well with the application.  A password safe with randomly generated passwords, stored in encrypted form, is probably a better solution in most cases. [Updated 2 November 2013: Authy uses the same TOTP mechanism as Google Authenticator, but encrypts the secret key on the client side.  That encryption is really more obfuscation than encryption since the key is based on phone attributes and can potentially be reverse engineered.]

As I've set it up, I'm still relying on SSH public key authentication for SSH logins, and on certificate authentication for VPN logins, in addition to Google Authenticator.  For the case of logging into my VPN from my laptop and having Google Authenticator on a separate mobile device, it does seem to be a security improvement (though I welcome anyone to show me that the gains are illusory).

UPDATE (July 31, 2019): Note that you should make the .totp-key file in the user's home directory owned by and only readable by root, or else you're effectively permitting that user to do passwordless doas/sudo, since passworded doas/sudo will use the TOTP mechanism for authentication. That won't stop the user from removing the .totp-key file and replacing it with their own, but at least that action becomes detectible. To prevent removal, on OpenBSD you can set the file to be immutable (schg flag) and run at securelevel=2. But a better solution would really be to put those secrets somewhere outside of the individual user's home directory.

UPDATE (October 22, 2019): The OpenVPN authentication with 2FA is broken in OpenBSD 6.6, it now leads to user/password authentication failures. Not sure why yet.

UPDATE (October 22, 2019 #2): Looks like it may have been user error, it works now, though I did update my _openvpnusers group to the new number (811) from the old one (596), but the number itself shouldn't be hardcoded in openvpn_bsdauth, so that shouldn't have had an impact.

UPDATE (30 October 2022): Also see Solene Rapenne's blog post on this same topic.

Matt Dillahunty and disbelief by default

In his recent talk at the American Atheist convention on skepticism and atheism, Matt Dillahunty states (at about five minutes in) that skepticism does tell us what to believe in the case of untestable claims--that the default position is disbelief.

But no, the default position has to be nonbelief, not disbelief.  To disbelieve in a proposition is to believe in the negation of the proposition, to believe that the original proposition is false.  And Dillahunty already said that (a) we should proportion our belief to the evidence and that (b) the proposition in question is untestable, meaning there is no evidence for or against it.

The position he describes is logically inconsistent.

We know that there are untestable propositions that are true.  We shouldn't believe that they are false simply because they are untestable. We should only believe they are false if we have good reasons to believe they are false; in the absence of that we should be agnostic.

(Added 5:36 p.m.: What are the implications for the above argument if it is the case that untestability does not entail lack of evidence or reasons?  What about if we distinguish evidential from non-evidential reasons?  And if we take the latter course, what does that say about proposition (a), above? Left as an exercise for commenters.)

Isaac Funk and the Widow's Mite

One of the more interesting and better documented cases of surprisingly accurate information from a spirit medium that is described in Deborah Blum's fascinating book, Ghost Hunters: William James and the Search for Scientific Proof of Life After Death (2006, Penguin Books), is the case of Isaac Funk and the Widow's Mite (pp. 260-262).

Funk, of Funk & Wagnall's Dictionary, had been visiting a medium in Brooklyn, New York in February 1903.  About his third visit, he subsequently described the following (in Isaac K. Funk, The Widow's Mite and Other Psychic Phenomena (1904, Funk & Wagnalls), pp. 159-160, now in the public domain due to copyright expiration):
About eleven o'clock the control named "George," in his usual strong masculine voice, abruptly asked: "Has anyone here got anything that belonged to Mr. Beecher?" There was no reply. On his emphatic repetition of the question, I replied, being the only one present, as I felt sure, who had ever had any immediate acquaintance with Mr. Beecher: "I have in my pocket a letter from Rev. Dr. Hillis, Mr. Beecher's successor.  Is that what you mean?" 
The answer was: "No; I am told by a spirit present, John Rakestraw, that Mr. Beecher, who is not present, is concerned about an ancient coin, 'The Widow's Mite.' This coin is out of its place, and should be returned. It has long been away, and Mr. Beecher wishes it returned, and he looks to you, doctor, to return it." 
I was considerably surprised, and asked: "What do you mean by saying that he looks to me to return it? I have no coin of Mr. Beecher's!" 
"I don't know anything about it except that I am told that this coin is out of place, and has been for a number of years, and that Mr. Beecher says you can find it and return it."
I remembered then that when we were making "The Standard Dictionary," some nine years before, I had borrowed from a gentleman in Brooklyn--a close friend of Mr. Beecher's, who died several years ago--a valuable ancient coin known as "The Widow's Mite."  He told me that this coin was worth hundreds of dollars, and, under promise that I would see that it was returned to the collection where it belonged, he would loan it to me. ... 
I said to the control, "The only 'Widow's Mite' that has ever been in my charge was one that I borrowed some years ago from a gentleman in Brooklyn; this I promptly returned"; to which the control replied: 
"This one has not been returned." And then, after a moment's silence, he said: "Do you know whether there is a large iron safe in Plymouth Church?" 
I answered: "I do not." 
He said: "I am impressed that this coin is in a large iron safe, that it has been lost sight of; it is in a drawer in this safe under a lot of papers, and that you can find it, and Mr. Beecher wishes you to find it." 
I said: "Do you mean that this safe is in Plymouth Church?" 
He said: "I don't know where it is. I am simply impressed that it is in a large iron safe in a drawer under a lot of papers, and has been lost sight of for years, and that you can find it, and Mr. Beecher wishes you to find it. That is all that I can tell you."
Funk goes on to inquire of his business manager, who insists that it was returned, and of Mr. Wagnalls and Wheeler, who knew nothing of the coin, but Wheeler, a skeptic, suggests that it's a good test.  Funk asks a cashier, who remembers the coin, but also says that it had been returned, to investigate.  After twenty minutes, the cashier returns with an envelope containing two "Widow's Mites," which was located in one of two safes (the large iron one), in a drawer under papers.

The two coins are a smaller light-colored one and a larger black one, and Funk recalls that the smaller one was used for the illustration in the dictionary and that it was the genuine article, while the other was a fake.  He returns to the medium, and asks which coin is the right one.  Contrary to his belief, the medium (as "George") says that it is the black one, and that the friend of Mr. Beecher's to whom it belongs is a man associated with a large ladies' school in Brooklyn Heights.  Funk recalls that it was borrowed from Prof. Charles E. West, head of a ladies' school in Brooklyn Heights.

Funk sends both coins to the Philadelphia Mint for examination, and they determine that the medium is correct, the black one is the correct one, and the wrong one was used for the illustration in the dictionary.

Funk notes that the preface of the dictionary notes, regarding the illustrations, contains the description "The Widow's Mite (which was engraved from an excellent original coin in the possession of Prof. Charles E. West of Brooklyn, N.Y.)."

Funk's book provides a number of affidavits supporting the recounting of events, including that only two people present with the medium knew of Funk's connection to the coin (Funk and Irving Roney, the latter of whom provided an affidavit), that no one knew that the coin had not been returned, and that the cashier staff had no knowledge of the coin which was in the safe in their office.

The coin was returned to West's son, who also provides an affidavit stating that he was unaware that the coin had not been returned and assumed that it had been.  Funk says he dined repeatedly with the elder West prior to his death, and the coin was never brought up.

Funk proceeds to list a series of facts about the case and some possible explanations (pp. 168ff), and finds difficulties with fraud, coincidence, telepathy and clairvoyance, and spirit communications as explanations, though he appears to favor the last of these.

Funk presented the case to a number of eminent scientists of the day, including William James, Alfred Russell Wallace, and William Crookes, of which those listed were all associated with the SPR or ASPR and each suggested spirits as a possible explanation.  Many of the other scientists and philosophers, however, suggested fraud or deception (see table in Funk's book, pp. 177-178).

As presented in Blum's book, this case seems more impressive than it does with all of the details in Funk's account.  What I find suspicious are that the medium is located in the same city as the person from whom the coin was borrowed, that the connection between the owner of the coin and the illustration was published in Funk's dictionary (omitted by Blum), and that although the son had forgotten about the coin being loaned out, he thought "it altogether likely that his father told at the time other members of his family, and possibly some persons outside the family" (Funk, p. 174).  All that it would take for the fraud hypothesis would be that the medium had heard, second-hand, about the never-returned coin, and speculated that it had been forgotten and was kept in a safe (and perhaps offered a guess about which coin was genuine; that information has no clear source from the details recounted).  Funk infers that because West never brought up the coin that he had forgotten about it, but that is an assumption on his part--perhaps West made periodic complaints about it not having been returned, but didn't mention it to his son.  Funk suggests, based on class distinctions, that no one in the medium circle other than himself would have known that West even existed, which seems a highly questionable assumption.

The Decline (and Probable Fall) of the Scientology Empire

My talk from January 19, 2013 to the National Capitol Area Skeptics is now online!

Thanks very much to the NCAS for professionally recording and editing this video.

I've included some notes and comments below.


  • 0:50 & 42:29 "Advanced Teachings" available at all Advanced Orgs are up to OT V. Advanced Orgs can deliver through OT V; OT VI & VII can only be obtained at the Flag Service Organization (FSO) in Clearwater, FL, and OT VIII can only be obtained on Scientology's cruise ship, the Freewinds. See: http://www.xenu.net/archive/ot/
  • 8:01 German U-boat -- I should have said Japanese submarine
  • 9:14 Photo is often claimed to be from 1968 but is really from 1959-60, so Cleve Backster probably wasn't the source of Hubbard's claim, as I originally said in the talk (also see my previous blog post on this topic).
  • 10:53 Aleister Crowley is pronounced "crow-lee," not "craugh-lee" (I have apparently have not broken a bad habit of following Ozzy Osbourne's pronunciation).
  • 13:59 the Fraser Mansion, though referred to by Scientology as the "founding church" from the 1970s to 2010, wasn't the original building. The original building, at 1812 19th St. NW, is now a museum called the L. Ron Hubbard House (though his house was across the street), which the church acquired in 2004. The Fraser Mansion is now Scientology's National Affairs Office.
  • 14:11 The first use of the name "Church of Scientology" was by the Church of Scientology founded in Camden, N.J. in Dec. 1953; the first Church of Scientology corporation was in Los Angeles (Feb. 1954, which became the Church of Scientology of California in 1956), the Church of Scientology of Arizona was incorporated that same year. Hubbard's organization while he lived in Phoenix was the Hubbard Association of Scientologists, International (HASI), founded in Sep. 1952. All HASI assets were folded into the Church of Scientology of California in 1966.
  • 31:07 "Division 20" should have been "Department 20."
  • 32:43 "bad status" -- Scientology "conditions" are a scale, like the tone scale, that your "ethics" are in, which are positive or negative. For each condition there is a "conditions formula" you are supposed to apply to get to the next better condition. Those assigned to the RPF are put in a condition of "liability" (the rag on arm mentioned is a sign of the condition of liability). See: http://www.cs.cmu.edu/~dst/Library/Shelf/wakefield/us-11.html
  • 41:07 PIs following the Broekers--mainly Pat Broeker; after one apparent attempt to leave (described in Lawrence Wright's book, Going Clear), Annie Broeker remained in Scientology until her death. Tony Ortega describes the testimony of the two PIs, who spoke out for one day before their lawsuit with Scientology was settled: http://tonyortega.org/2012/11/29/scientologys-master-spies/
  • 43:22 Lawrence Wright's book says that "Int Base" and "Gold Base" are two different bases at the same location; "Int" being the international headquarters and "Gold" named after Golden Era Studios.
  • 1:05:35 "dog was drowned" -- Judge Swearinger's dog, Duke, a miniature collie, drowned, it's not certain that it "was drowned."
  • 1:07:10 "unable to attend uncle's funeral" -- Hubbard died on January 24, 1986; the Challenger explosion was January 28, 1986.
  • 1:17:43 St. Louis Ideal Org.  The pictured Masonic Temple is not the St. Louis Ideal Org, which is still under construction. (Thanks to ThetanBait on YouTube for this correction.)
  • Narconon's drug purification program involves vitamin (esp. niacin) megadoses, but "injections" is not correct.
