One of the most impressive aspects of Yellowstone is just how unusual a spot on earth it is. Its one of just a handful of sites on the earth where heat, water and geology conspire to create geysers and pools.

You can see that this D300 image was captured very close to the iPhone image I posted yesterday. Interesting comparison.

I knew from the first days with my iPhone 4 that I wasn’t going to need a small camera for snaps because of its quality.

Imagine my surprise when I discovered that the Yellowstone image I posted yesterday showed up on Flickr as geotagged. Why? It was an iPhone image.

I ran some noise reduction on the image before posting because of pattern noise in the trees at the upper third of the image but I thought that was from aggressive post processing of shadows. Unusual for the Nikon D300.

Just astounding really.

Making decisions always limits future options. Choosing one of two forks in the road precludes taking the other fork without added costs of backtracking and starting over. Moving into the future, the decision space is always changing. In some ways it collapses because choices not made disappear and become unavailable. But at the same time, the decision space expands and the chosen path is traveled.

I love thinking about making decisions at the start. Clean sheet of paper and infinite possibilities. Yet that is an entirely artificial metaphor. We always find ourselves in the middle of the story. And here there are many constraints that are the consequences made previously, often by others. Whenever I hear discussions about the US Federal Budget deficits, I think about these constraints. Large systems have been created over the years (Social Security, Medicare and Medicaid) to prevent the widespread poverty and lack of medical care that were once commonplace among the elderly. Having created these systems, it becomes unthinkable (impossible?) to end them even as they require larger and larger resources every year. Having been created with no built in limits or budgets, these entitlements grow and grow, limited only by the ingenuity of those in my industries, medical care and drug development.

The decisions made early on, when these programs were smaller, have led to unintended consequences which could be catastrophic in a few years or decades. But now it seems that changing paths to avoid these outcomes may not be among the choices that can be made by the government.

I wonder whether there is an inevitability to certain outcomes once choices are made and systems created. Are these some kind of local minimum from which escape is impossible? Must it be the catastrophe that opens up new decision space? I use the metaphor of digging yourself into a hole. The hole gets so deep that one can no longer climb out, so that the more you dig, the deeper and more inescapable the hole becomes.

I can’t quite explain why we feel compelled to keep on digging when its clear that the path does not lead out but only deeper.

Usually I’m injecting light into images. Here I was working to take out way too much mid day glare against white mineral flows. It ended up looking almost overcast as I brought out the detail and color.

One of my rare verticals.

One of my most vivid insights during my first years in training as a Neurologist was the realization that the brain functioned as a mosaic. The many divisions of the brain  each has its own function- they collaborate but work largely independently. When part of the brain is damaged by a stroke, after a period that’s like shock, the rest of the brain carries on as before, just missing an ability due to the loss of function. It’s a lot like loosing a limb. Loose the part of the brain that produces speech, moves the left arm or sees the right side of the world and those particular abilities are deleted.

Its hard to reconcile this view of brain as mosaic with our subjective sensation of a single “I”. There seems to be a single identity inside each of us that we identify as ourselves, as our consciousness, our mind. We wonder whether animals have a similar unitary experience of identity. And we wonder whether a machine could ever experience self.

Putting aside these interesting questions about animal and computer minds, there is a related question of where the mind resides. To my pragmatic way of thinking, asking where these sensations are experienced is like asking where in some one’s body the personhood resides. I am my body and no matter how many parts of my body might be lost or replaced, my personhood is my body. Simply. The truly remarkable subjective illusion of conscious unity makes it seems like the mind has to be something or somewhere other than just the function of the brain in its totality. But I say that this mind is a mosaic of functioning brain areas.

I haven’t read Damasio’s latest: Self Comes to Mind: Constructing the Conscious Brain, but I did see the review in the NYT by Ned Block. It interesting how Block wants to define consciousness much as I do, this odd subjective sensation of inhabiting a brain that interacts with an environment, criticizing Damasio for emphasizing “knowledge of one’s own existence and of the existence of surroundings.”

Damasio has been interested in how the subjective sensation of awareness arises in the brain. It seems unfair for Block to review a book by criticizing the author’s choice of subject rather than their approach to the subject. These questions of self awareness and more abstract thought are really more interesting than mapping experience in the brain. Damasio’s subject here seems to be the one that I’ve been writing about recently, which is how we view the metaphor and artifacts that we create in a uniquely human way. Language, metaphore and, above all I think, models capable of  running internal mental simulations are what let us imagine, plan and coordinate activity in ways never before seen on the planet.

I want to link this neurobiology of experience with the growing understanding of how language and metaphor are embodied in the brain and environment. I’m more and more convinced that the more real we see these abstractions as being real, the better we can deal with them in the world. My best example of this currently is equating fear, the emotion, with loss of control, loss of the feeling of mastery.

After all, making decisions under conditions of uncertainty can not be done well if motivated by fear of unknown, uncontrollable future events.

I never got the GTD focus on context.

While David Allen’s Getting Things Done was a big influence on my approach to simplifying life. I embraced the clean desk, the labeled files and next action approach quickly with great gains in effectiveness. But while I tried to adopt his approach to filing next actions by context, it never stuck. I never saw the value in it other than keeping an “errands” list.

Context should be a powerful organizing principle. After all, the options available to choose from should be strongly dependent on what’s in front of you. Moving from place to place should be equivalent to moving from task to task. Even in the virtual world, moving from Photoshop to Word should be a context shift.

We’ve pretty much erased context with technology. Communications channels are open and available 24/7. There are synchronous channels like phone calls that require the other party to be available and willing to talk. There are asynchronous channels like email and social networks that have variable latency but are always available. Except for physical errand involving material goods- grocery shopping, dry cleaning for example or other people- business meetings, haircuts, I can pretty much do any work I want to anywhere I am.

So there’s no context guiding action. In fact complexity in introduced by the sheer number of different ways I can do anything at any time. Want to jot down a note? There’s my pen and notebook. Or a post-it-note. Or Evernote. Evernote on the iPhone, iPad, Mac Book Pro, work Windows XP laptop. Or email to myself.

Its true that one solution would be to impoverish myself by eliminating choices. Do I need the Evernote on iPad option? Do I really need the iPad at all? Maybe I could just do everything on the iPhone.

I think choice is good. I’d rather have options, but find it helpful to take a moment and create what are basically rituals. Conscious, stereotyped behavior that’s consistent and relatively arbitrary just so that I don’t keep making the same decisions over and over again and then spending more time unravelling what I’ve done after the fact.

Ritual is human way to collapse complexity into simpler behavior paths and gain more control over the cognitive environment.

This is a bit of an experiment with Photoshop’s Lighting Effects filter. Vincent Versace uses it extensively to light photographs after the fact. In this image, I was trying to be subtle about making what was relatively flat lighting with nice texture into something that was pretty convincingly sunlit.

Perhaps its a bit too subtle, but it certainly is a believable unreality to my eye.
