Peter Boghossian engaged in a
rather strange debate* with a guy called Richard Shumack a few years
ago in which he laid out the characteristics of delusion. To be deluded, Boghossian maintained, using
the words of Karl Jaspers,
you have to sincerely hold a belief that is implausible,
and that belief has to be incorrigible. In other words, you really need to believe
what you say you believe (you can’t just be mouthing a commonly held belief and
you can’t be just joking with someone).
You can’t be argued out of that belief.
And the belief must not only be false, it must be unbelievable by a
reasonable person or the evidence must be heavily stacked against it.
The last two criteria are very closely linked,
incorrigibility and implausibility, because the more you refuse to accept
evidence against your claims and more questionable the “evidence” brought
forward in support of your claims, the more implausible your claims are.
To show that your belief is not a delusion you need to
demonstrate two things, 1) the claims associated with that belief are plausible
and 2) you are willing to change the nature of your belief in the presence of
contradicting evidence.
Boghossian showed, with some technical issues, a short clip
with William Lane Craig talking about the nature of “faith”. WLC quite clearly states that if “in some
historically contingent circumstances” the weight of evidence turned against
christianity, then it would not affect his faith because he has “the witness of
the holy spirit in (his) heart”. Under
WLC’s interpretation of the “proper relationship between faith and reason”,
faith trumps reason – or perhaps we could less kindly say that, when in a
“proper relationship”, faith ignores reason, at least when reason
indicates that the contents of faith are wrong.
Additionally, he makes an unsubstantiated claim (at least not in this context,
it can be implied that the substantiation is biblical) that if a believer has
intellectual doubts, then that can be attributed to Satan who is forever trying
to destroy faith thus implying that any effort of reason that speaks against
faith could always due to be satanic influences and providing a theological motivation
for ignoring reason.
This is very much an indication that WLC is almost all the
way to delusion – his beliefs appear to be sincerely held (he’s not a
televangelist, so he doesn’t appear to be in it for the money like Kenneth
Copeland [net worh $760M] or even Billy Graham [net worth $25M]), his beliefs
are incorrigible by his own admission and the beliefs are inherently
implausible because they include (amongst other things) belief in miracles
which are, by definition, implausible.
The only thing that could save WLC from delusion would be
truth of his claims under theism – if his god were to exist.
The debate, however, was not Boghossian vs. WLC, it was
Boghossian vs. Shumack. Shumack appeared
to do well enough against the one prong of the Boghossian attack, his attempt
to explain that if we are going to “know” something then we need to bring empirical
evidence – so a tape measure to obtain the dimensions of a door, not divination,
or a dog’s opinion, or the ceremonial sacrifice of a goat.
It should be noted however that this example was raised in
the context of explaining that there can be better and worse ways of “knowing”
things. For measuring a door, a better
way is to bring a tape measure. If it’s
a standard, unmodified door, then you can look up the standard – but to know
whether it’s standard door, you need to measure it otherwise you’re just
guessing. Worse ways include guessing,
using woo and asking someone who has no reason to know the dimensions of the
door.
Shumack totally ignored the actual message and the
motivation behind the example. Instead,
he talked about how there are other ways to “know” things that do not call upon
empirical evidence – including the testimony of other people and one’s own
personal anecdotal evidence – without acknowledging that some of these ways, if
not all of them, are worse than empirical evidence.
He also ignored Boghossian’s follow-on from the door
example, the argument that we all want to increase the number of true beliefs
that we hold and reduce the number of false beliefs that we hold and that there
are two processes that work against that: holding beliefs that are not based on
evidence and holding beliefs based on what we believe to be evidence which is
actually not evidence. Note that I did
not remove the term “empirical” from Boghossian’s argument because Boghossian
didn’t use the term at this point. Sure,
he considers the tape measure to be a good device for obtaining evidence and
that evidence would be empirical evidence, but he implicitly accepts that there
are other kinds of evidence (not as good as empirical evidence, but evidence
nonetheless).
Directly after, Boghossian approaches the meat of his
presentation, in which he argues that religious belief is clearly delusional (so
much so that religious belief requires an explicit exemption in the DSM-V’s
definition of delusion).
Shumack did not address this at all. Even when given time to reflect and put his
words into an
opinion piece, he hardly addressed the issue (and then only in
passing while criticising “scientism”).
So, the key question was: Is Richard Shumack delusional?
Well, he’s a christian, so on those grounds he qualifies
since christian beliefs are (when done properly) sincerely held, incorrigible
and implausible. Unless his god actually
exists, of course, but Shumack didn’t make an effort to prove that his god
exists. His aim was to show that “theism
can be held by reasonable or reliable epistemology“.
I’m going to look, therefore, at delusion in terms of these
aims. I’m going to assume that Shumack
left that interaction with the belief that he succeeded in his aims (his
article written later made no admission that he failed to do so and I am
presuming that he is a sincere chap who would have acknowledged such a failure
if he believed that he had suffered one).
The video is up on line, and he has probably reviewed it and even if he
hasn’t the unwillingness to review evidence is problematic. If there is evidence in the video of that
debate that indicates that he failed to achieve his aim, then we can call his
belief incorrigible. All we need to do
now is work out whether a belief that he achieved his aim is plausible or not.
To do so, we need to assess what he presented in light of
what Boghossian had just said, specifically about better and worse types of
knowledge. Were any of the ways of
coming to knowledge described by Shumack sufficiently good as to be called
reasonable and/or reliable? Note that I
am going to discuss plausibility, given that believing in something plausible
is reasonable and clearly (although after the fact) a belief that turns out to
be reliable is thus shown to have been plausible.
Rather than relying on the video, I’m going to use his
washup at Eternity News for two reasons. First, it’s much easier to refer to than a
video, and second, a piece of published writing can be polished and perfected
while there is plenty of scope to misspeak while behind a speaker’s podium
(Boghossian referred to Shumack as “Robert” for example, while his name is
Richard). If there is something that he
said that was significantly better than in the written version, feel free to
let me know.
Shumack claims that “(c)hristian belief is based on all the
ordinary ways of knowing” and he lists them: intuition, second- or third-hand eyewitness
testimony, personal experience and, oddly, miracles. (His words, in context: “But
here there’s a great irony. Scientism is revealed to be an extraordinary and
unsustainable way of thinking about knowledge, whereas Christian belief is
based on all the ordinary ways of knowing. Christians sensibly ground so many
of their ethical and existential beliefs in intuition. Christians put their
faith in Jesus in large part based on the eyewitness testimony to the
historical events of his life, death and resurrection. Christians know God
personally through the presence of the Holy Spirit and they experience his
power through miracles like healing and visions.”)
What he leaves out are empirical evidence (my preferred
type) and logical argument (WLC’s second favourite after personal experience).
Are these, in the absence of a presupposition as to the
existence of a god, sufficient to make the belief in a god plausible?
The last shall be first, and in this case that is the humble
miracle. It’s a bit of a stretch to claim that this was actually in Shumack’s
list of “ordinary ways” but I want to address it anyway. A miracle, as earlier stated, is implausible
by definition. If your belief in
something is based on something else that itself is implausible, you’ve got a
problem right from the get go. If I
witness a miracle, I have to first consider it an aberration, a freak
confluence of events or a misunderstanding or misremembering on my part. If I am told about a miracle, I have to apply
the same doubts, and add to it any doubt relating to unreliability of the
witness. Note that when we consider a
miracle as the path to knowing, we must remember that that path passes through
either eye-witness testimony or personal experience.
So, we really only have three truly “ordinary ways”, unless
we drastically redefine the term “ordinary”: intuition, testimony and personal
experience. I have to point out here that
Shumack raised these three in the context of an attack on “scientism”, not an
attack on science. If the below seems a
bit too close to science, that should not be a problem per se, unless the
reader wants to accuse me of scientism on the grounds of sounding
too reasonable.
Let’s look at intuition.
What exactly is intuition? According
to the dictionary (well, a dictionary) it’s “the ability to understand
something instinctively, without the need for conscious reasoning”. Wikipedia says “Intuition
is the ability to acquire knowledge without proof,
evidence, or conscious reasoning, or without understanding how the knowledge
was acquired”. Well, that doesn’t augur well for Shumack’s initial aim (to
show that theism can be held by reasonable or reliable epistemology), since reason
itself has been jettisoned. Is intuition
reliable? It’s certainly not 100%
reliable, but perhaps it’s reliable enough for some things. Is it reliable enough to know about what
could be argued to be the most important thing you could ever know (were a god
to exist)?
I would argue not. Human
advances have steamrolled over incorrect intuitions for millennia. Logic exists to skewer intuitions and those
holding them and make our thinking better and more ordered. Consider Boghossian’s end-game regarding
better and worse ways to know things.
Which is better, a) knowledge acquired without proof, evidence, or
conscious reasoning, and/or without understanding how the knowledge was
acquired, or b) with proof, evidence and conscious reasoning, and with an
understanding as to how the knowledge was acquired?
Intuition might not be the worst way to start
a trip towards knowledge, but it’s far from being the whole journey. You certainly don’t want to rely solely on intuition,
you want something more substantial to get you to knowledge.
So, what about testimony?
I’m going to be outrageously fair here and consider only eye-witness
testimony, rather than second and third hand eye-witness testimony and
firsthand testimony to gossip and hearsay.
While eye-witness testimony has been considered the gold
standard in court cases (somewhat eclipsed now by forensic evidence), it has
always been dodgy. There is an
increasing body of work which shows that humans are unreliable eye-witnesses
but we don’t need to trawl through the scientific literature to make the
point. The point is adequately made for
us by christians who have a bible in which there are four gospels, all of which
differ to some extent or another. The
very need to include four perspectives relates to the unreliability of
testimony.
Perhaps considering the gospels as eye-witness testimony
might be thought of as a trap, but even if we consider the works as collations
of reports of people who may or may not have been eye-witnesses, we are still
relying on the ability (and will) of the authors to correctly relate what they
have been told and the reliability of the original eye-witnesses
whose tales have passed from person to person in an oral history tradition.
Add to this the fact that when a christian is accepting the
testimony of another they are treating their source as an authority for some
reason. If these authorities have
arrived at their knowledge via a questionable epistemology, then you are just
putting off the problem of how to arrive at knowledge rather than solving it.
And then we have personal experience. Personal experience is really no more than
zero hand (rather than firsthand) eye-witness testimony, since it only works as
a form of knowing when you relate your experiences back to yourself and try to
understand them and to place them in a comprehensible context. Above I pointed to the fact that there are
problems with the reliability of eye-witness testimony and this is not entirely
limited to people who are eye-witnesses and who are testifying to someone else.
All people are unreliable with regard to their own personal
experiences, to a greater or lesser extent.
They can be misled, confused and ignorant. They can leap to incorrect assumptions,
especially if sufficiently motivated to do so – as well they might be if life
eternal is on offer. They can
misinterpret their memories, muddle them up and even construct them out of
whole cloth where required (my younger brother used to clearly remember our
house burning down, despite it happening three months before he was born and a work
colleague often confidently reports events that no-one else in the office has
any recollection of, he’s so extremely non-synoptic that we could refer to him
as “John”).
As with intuition, and similarly to the eye-witness
testimony of others, personal experience is an adequate starting point on the
way to knowledge, but to bridge the gap between opinion and knowledge, we must
accept that our memories are questionable (when they aren’t better described as
feeble) and that we are plagued by confirmation and other biases. And, especially when what we think has
happened is rather odd, we must seek confirmation if we are going to transform
our personal experiences into knowledge of more than a memory (we will know
that we remember, but we won’t know that what we remember happened as we
remember it). To be of any use, that
confirmation is going to have to be via the collation and assessment of appropriate
evidence. In other words, via a sort of
scientific process – perhaps not the hardest of hard science, but at least some
sort of impartial evidence gathering and assessment process.
Is Richard Shumack delusional to think that he can know
anything via intuition, testimony and personal experience without taking
scientific-like steps to bridge the gap between his opinions (and
presuppositions) and actual knowledge? Yes,
I think he might be a tad delusional.
The only thing that might save him, allowing him to be
either accidentally in possession of knowledge or even correctly in possession
of knowledge (via a divine boost to the reliability a personal experience vis a
vis interactions with the holy spirit), would be the existence of his god. Unfortunately however, he made no real
attempt to show that his god exists.

* Note that I call the debate strange because of
its structure – 30 minutes for Peter Boghossian, 15 minutes for Richard
Shumack, 30 minutes for structured questions for clarification and then a
Q&A free-for-all. Usually a debate
gives each debater equal time to present their case. Perhaps Shumack felt that he could smash his
case in less time than Boghossian needed (along with less technology). He did, after all, have god on his side …
