Great insight into how the mind works
Book Review: "On Being Certain: Believing You Are Rights Even When You're Not" by Robert A. Burton, M.D.

In my theistic discussions; I am often fascinated (stymied) at the level of certainty that some theists have in the validity of their religious narrative...often in the face of clear contradictory empirical evidence. Over the years, I have taken a keen interest in neurology and how the brain works; enough so that I have a passing regret for not having gone into neurology instead of engineering (it's never too late, right?). Over these years, I have amassed a mental library of various illustrations that show how malleable and unreliable the mind (as manifested in the brain) can be. Still; the inexplicable certainty that some possess was never addressed directly in my readings. Hence, when I saw a brief blurb about the book "On Being Certain", I immediately went and bought a copy (my library had ordered it, but they did not yet have it ready for lending).

Dr. Burton's sole focus of "On Being Certain" is that sense of certainty that we all recognize. He provides evidence that the feeling (or `emotion' more accurately) is a `primary emotion' and refers to it as the "feeling of knowing" (he did not shorten it to an acronym, I think, because of the obvious, awkward acronym that would result).

Burton cites the rapidly accumulating knowledge that we have with regard to brain function and perception to good end. The less diligent reader, though, might not find the reading deeply satisfying as we cannot, based on our current knowledge, fully answer specific questions (i.e. why do we create gods to address the unknown). Still, the empirical evidence cited is often clearly in conflict with some common presumptions. This, in my mind, is the true purpose of the empirical method. While we may be unable to answer a specific, granular question on a topic, we can effectively eliminate the wrong answers...and Burton's book does go a long way in eliminating some of those wrong answers (at least for those open to empirical evidence).

One interesting point Burton makes is there are some emotions that we can induce through direct electrical stimulation of very specific regions of the brain. One example is the "sense of another presence" (i.e. that there is someone or something nearby). Another example is the disruption/manipulation of the "sense of self" where we can feel separate from our bodies (floating) or feel "at one" with our surroundings. The point of his book, of course, is that "feeling of knowing" which can be elicited through electrical stimulation. Burton calls these "primary emotions" and are localized to very specific areas of the brain. On the other hand, we have no evidence of being able to similarly induce higher order emotions such as the "sense of irony". Burton effectively demonstrates how these primary emotions (particularly the "feeling of knowing") do not necessarily reliably correlate with facts or reality.

Reading the book, while mentally critiquing it, is a bit of a mobius-like conundrum. You are simultaneously judging and amassing knowledge, while you are reading about how your judgment and knowledge is not reliable. WHEW! I will confess; I feel that Burton, on one or two occasions, overstepped the implications of bits of evidence. In his defense, the book was written for a more general audience and some background that might have been omitted might justify his positions. In all, the book offers some fascinating insights as to how our brains and minds work and an astute reader can learn much from it.

Entertaining and Interesting, but...
I am always slightly annoyed when a book is not about what is is supposed to be about. A few chapters of this book - those towards the end - are on why the feeling of certainty is just that: a feeling. This leads the author to some interesting discussions about how the 'feeling of certianty (a feeling though it is) is something that tends not to be subject to reason, but owes more to emotion. The author also goes into some really interesting thoughts about evolutionary reasons why the feeling of certainty as a tool to help us survive in an uncertain world (where we have to act, so we might as well act with conviction).

Unfortunately, this only happens well into the second half of the book (maybe 2/3rds of the way through). The first many chapters are stage setters. There are chapters about distinguishing what is meant by "mental states," "feeling" and "sensation," chapters describing how we know that emotions like fear, deja vu, and religious experience are chemical in nature, and how the "mind" is an emergent property tying together several components of the brain into a unity.

The author also spends quite a bit of time talking about what neuroscientists term the "hidden layer." That is, when we make decisions, the brain "surveys" a whole host of things - past experiences, attitudes one has acquired, things one has learned, etc. - to come to a conclusion, but this is all "hidden" form our consciousness. Thus, the author concludes that while we may feel like our deliberations are conscious, often the bulk of our deliberation is unconscious.

All of this, the author tells us, supports the thesis (that he eventually gets to) suggesting that certainty is a feeling,, and not always one subject to rationality as we generally assume. Since we have seen that attitudes like fear, deja vu, and sense of purpose are feelings like any other, and we have seen that feelings like these are often not subject to rationality (try convincing a clinically depressed person that the feeling of purposelessness is only a chemical "illusion"), and we know that much of our thought is unconcious, we can also infer that the feeling of certianty is subject to all of these. (Try convincing a young-earth creationist that the earth is more than 6,000 years old and that their certainty is not due to the strength of the idea.)

Really, I don't have any huge qualms with this. We've all seen people be so certain of something that is (to us) obviously wrong, and know all to well that people's attachment to ideas often has not a thing to do with rationality. (And we all, if we are honest, realize that we have been the 'dummy' in this scenario as well.)

My biggest problem, from a literary standpoit, is that the author takes a very long time to get to his point, beginning many chapters with something like: "I want to talk about the feeling of certainty. But first, let's..." Once that happens too many times, I begin to lose patience, particularly when some chapters (like that reviewing the difference between "feelings" and "sensations") simply go on longer than they should.

My philosophical beefs with the book is: the author, who suggests may times that we cannot step beyond our feelings of certainty if they are strong enough, would be well served to have included a chapter on examples where people DO change their minds about things they were once deeply certain about. The fact that this happens - albeit happens only with difficulty and pain - gives empirical lie to this thesis.

Really, this is a quite interesting book with an interesting case that simply takes the author too many pages to make. I resisted the urge to skip ahead numerous times (and did skip half a chapter that seemed to veer frequently off topic). I wish the author would have discussed the issue of 'certainty' more than the tertiarilly related matter of brain states like fear and deja vu.

In the end, I would reccomend this book to people as a follow-up read to books like "Mistakes Were Made," which give a much more direct discussion of our brain's tendency to fall into illusions of certainty. This book does that, but simply tries to do so much more that it may better have been written as a collection of loosely related essays.

Another thoughful book on how the brain makes decisions
We are challenged by certainty our own and that of others which are often in turbulent conflict across many fields. It is difficult to understand how we as individuals and as groups can feel so deeply certain and so differently about a given issue. Here is a book that reviews such matters in modern terms both from a personal and from a professional neuroscience perspective, showing how and why our convictions are neurologically our own. He does so be citing examples from clinical practice, but without overloading the reader with difficult technical terms. At the same time, interesting examples and personal experiences both broaden and enlighten the presentation. His motivation to address the topic is never hidden. His message is that even with the best of scientific proof we can never be as certain as we commonly think (and feel) we are. What we do not know (or have not yet dreamed of) vastly exceeds what we know. The small voice of skepticism should always be in our ear. It is more than an admonition, it is a necessity. Those who liked the books by Oliver Sacks will like this book.
