YELLING AT THE PRESS
Lou,
I've hounded you in past about the paper becoming more relevant. This instance of the girl who has injured herself with acid is a case in point.
One of your commentators mentioned "Munchausen's syndrome". That syndrome, as well as many more, are being deeply explored in the fields of neuroscience and/or evolutionary psychology. Unlike psychology of the past, these new fields are hard science, based in new techniques for imaging and analyzing the brain and its functions.
Central to their findings is the idea that the brain is not and has never been a blank slate upon which any culture can write any lesson which they care to. The core finding of these new sciences is that the brain is an accumulation of hundreds and thousands of minute adaptations over time (minute computing devices with specific and limited duties) which have culminated (for the moment) in the modern brain which first appeared between 50 and 100 thousand years ago with all its strict limitations and its soaring strengths.
Reading in these fields will open any mind (and the minds of your readers) to what an amazing device the brain is. It contains all that is us, all the chemistry of our feelings and thoughts. The brainRus, so to speak, and its physical functioning produces every nuance of personality that others perceive in us. These states which we label "emotions" and talk about as if they were some sort of soul-state or airy-fairy presence within us are actually electro-chemical states of the body which evolved for the regulation of human decisions. Understanding these basic facts would go a long way toward humanity's beginning to get ahold of ourselves and our actions. Right now, we humans are pretty much by nature out of control of our actions.
These new findings are as important in the long run as Darwin's discover of the mechanisms of natural selection in the biological world. Is it not the duty of a newspaper to inform the public of new findings which may alter humanity's self-perceptions and our functioning in the Cosmos?
David Brooks, the once-upon-a-time conservative writer, brought up this new field of science in a recent conversation with Charlie Rose. He sees its importance as much as anyone in your line of work. That's why I mention him.
Good luck and good reading,

THOSE MIXED UP NEURONS
After I retired a few years back, I took a couple of algebra/mathematics courses. I noticed a strange quirk in my mental processes. Frequently four years ago when I meant to write down x, I would write down the numeral 8. Recently, I've begun working through my old algebra textbook in order to get to a new unused textbook I bought and wasn't able to use back in Spokane because my wife and I moved to Vancouver. This morning, I was doing the exercises at the end of a section, and I wrote down 4 when I meant to write down +. I'm still also confusing quite frequently the 8 and the x.
So, according to my poor befuddled neurons
8 looks like x sometimes and
4 looks like + sometimes also.
These slips occur when I'm lost in the overall algebraic function I'm doing and not always paying attention to the finer details that my hand is putting on the paper. But I can see how certain neurons which are responsible for curves and curlicues can get confused between x and 8 and I can see how the neurons responsible for lines that are vertical and horizontal and which intersect in the figures for numeral 4 and a + sign can also get confused when I'm not paying strict attention and am slightly distracted.
Now isn't that fascinating to catch our neurons at work like that?

MINDFULNESS
Neuroscience is still trying to unravel the nature of consciousness and the origin of mind in the human animal. Here are some more theories.
[OPEN QUOTE]
This also led to speculation as to which species did or did not have theory of mind and at what point in evolution it appeared in humans (Povinelli & Preuss, 1995).
There are two distinct origin scenarios for our capacity to understand intentional agency, to create representations of other agents' behavior, beliefs, and intentions. A widely accepted social intelligence scenario is that higher primates evolved more and more complex intentional-psychology systems to deal with social interaction. Having larger groups, more stable interaction, and more efficient coordination with other agents all bring out, given the right circumstances, significant adaptive benefits for the individual. But they all require finer and finer grained descriptions of other agents' behaviors. Social intelligence triggers an arms race resulting from higher capacity to manipulate others and a higher capacity to resist such manipulation (Whiten, 1991). It also allows the development of coalitional alliance, based on a computation of other agents' commitments to a particular purpose (hunting, warfare; Kurzban & Leary, 2001), as well as the development of friendship as an insurance policy against variance in resources (Tooby & Cosmides, 1996).

Another possible account is that (at least some aspects of) theory of mind evolved in the context of predator-prey interaction (Barrett, 1999, this volume). A heightened capacity to remain undetected by either predator or prey, as well as a better sense of how these "other" animals detect us, are of obvious adaptive significance for survival problems such as eating and avoiding being eaten. Indeed, some primatologists have speculated that detection of predators may have been the primary context for the evolution of agency concepts (van Schaik & Van Hooff, 1983). In the archaeological record, changes toward more flexible hunting patterns in modern humans suggest a richer, more intentional representation of the hunted animal (Mithen, 1996). Hunting and predator avoidance become much better when they are more flexible, that is, informed by contingent details about the situation at hand, so that the human does not react to all predators or prey in the same way.

DÉJÀ VU
According to recent research, which makes very good sense, déjà vu is a memory problem. Well “of course” we all say. What else could it be! As for me—the article goes on to say that it tends to happen more as one ages and is also a problem in Alzheimer’s patients. I don’t know about the rest of you, but I used to have a lot more déjà vu moments when I was younger, when I was drinking, which also makes a lot of sense when I think about it. It’s been a long time since I’ve had a déjà vu experience, a long time. What about you? Read the whole article here.
PS: If you notice that I’m making fewer or shorter blog entries that’s because my interest in writing creatively seems to have reappeared. I’ve begun my first novel in more than 15 years—or longer—and I’m combing over my poetry with an eye to putting together a book of my best writing there too. Currently, I'm working through a book on neuroscience called, The Feeling of What Happens and a book by Tobin about Ernie Pyle, called Ernie Pyle's War.
