Breaking Trail

For the umpteenth time, my snowshoe breaks through the crust and dives into hopeless depth hoar. The continental snowpack nibbles away at one’s soul with a false promise in every step. The crust feels solid when one’s foot first rests upon it. It even holds as weight shifts from back foot to front foot. But, it can sense when the full weight of body and pack has shifted, and then it collapses.

The slog would be bad enough were it a grueling monotony of breakthrough after breakthrough, but it is worse that that. Because sometimes, the crust gives you a few steps on top, and just when you relax, then it lets you fall through into the great vat of cornstarch beneath. What’s still worse about my current situation is that I am following a trail. Minus the snow, it would be easy walking.

If I persist, I will soon get a little psychological boost, as my course turns off the cut trail and into untracked forest. Though it really isn’t any harder or easier than wallowing above the Summer trail, breaking off the established path onto the section that only I know, feels like progress and is an antidote to the demoralizing snow conditions.

I used to do the walk to high camp with a map and compass. I no longer need those. The rocks, trees, sequences of slopes and their conformations chart a more accurate course in my memory. These days, I can get to my destination despite the snow cover because the trail isn’t really on the ground; it is in my mind. Or, so it would seem,

One might say that the trail presupposes or lies in the potential of, my mind and memory. For a trail to be, the possibility of a trail must have been. But the trail is not made of possibilities. It is made of my memories of trees, slopes, rocks, and all the other landmarks on the way. It is made of my senses of time, space and distance, which are properties of the phenomena which constitute thought and memory. My memory, and its possibilities, are dependent upon its contents. And so it is with memory in general; it is defined by having extant referents.

In other words, my memory is nothing without memories, and all the possibilities of memory lie in its contents, including its metaphysical possibilities, which lie in its having contents. When I recall looking down the trail in this moment, I trace a path through the space and time of my memory, just as I did when I stood in the snow on the day I recall. And I do so on background – all the historical infrastructure which orients my current experience and dictates its aspectual shape.

My recollection at the keyboard can’t get going without the background, yet the background can’t be background except in relation to current experience, which links it all together. The possibility of a trail inheres in legs, eyes, slopes and trees. Memory resides in its defining contents. The contents of my memory rely upon where and when I am now.

Some folks get frustrated with all this interdependence and would retreat to the simple certainty of a hierarchy. I can understand the appeal of a world where there is a separate mental substance, an uncaused cause, memory as an independent faculty among other independent faculties, and a trail waiting beneath the snow to accommodate our walk without the hard work of trail breaking.

But that means a world where there may be memory which doesn’t necessarily remember anything, a mind which doesn’t necessarily think about anything,  an agent which does not experience the changes it makes, and destinations which don’t belong to anybody – a world which is not possible.

Shrimp Eyes

An answer to the post “What Is Knowledge?” at Self-Aware Patterns. If you don’t want to keep reading this, go read that…

—————————————————————————————————————————————–

Imagine…the mantis shrimp sees zorp. Zorp is a color beyond deep violet, and it is a color which humans cannot see, because humans only have 4 of the 16 color receptors which the mantis shrimp eye possesses.

Once upon a time, long before anyone looked inside a mantis shrimp’s eye, a group of marine biologists set out to test the shrimp’s sense of smell. In those days, nobody had looked in a shrimp’s nose either, to map out the nerves and chemical receptors. So, the only way that the biologists could learn about shrimp olfaction was to wave something smelly under a live animal’s nose and see what happened.

The experiment went like this: The shrimp entered a bare tank from an isolation chamber at one end. Prior to the shrimp entering, the biologists had secretly painted a random corner with an invisible, smelly substance. Upon release, if it swam to the marked corner, the shrimp got a treat.

After a bit of trial and error, the shrimp picked up the trick; it swam to the marked corner every time. Mantis shrimp had an acute sense of smell. But the truth is: mantis shrimp could not smell a damned thing. Unbeknownst to the investigators, the invisible, smelly substance which they used to mark the corner glowed zorp.

As it turned out, by sad, chemical coincidence everything smelly,  glowed zorp. Without understanding the micro-structure of mantis shrimp senses, the situation was hopeless. Only the shrimp would ever know the truth. Yet the biologists did know something. They got a predictive model of shrimp behavior out of their experiment. If they wanted to make shrimp bait, keep shrimp away from swimming areas, or start a shrimp circus, they had a reliable, practical theory to help them – they knew how to do it.

Furthermore, they did have some truth, even if it was not the shrimp’s truth. Because, the biologists stated the outcome of their experiment carefully.

Mantis shrimp were observed to preferentially swim to a corner marked with Fragrance 5 after receiving a standard shrimp kibble in association with alighting upon a Fragrance 5 mark in 3 previous instances.”

Obviously, the truth itself does not get you a shrimp circus or anything else. The truth, being blatant, does no work.

Yet we think that we seek the truth when we seek knowledge. We have been told that knowledge is justified, true belief. Indeed, the justification-belief relationship seems unbreakable. If justification is a well constructed story, then all our beliefs have it, as we have somehow arrived at those beliefs. And, we certainly distinguish between things we know and things we merely believe, on a functional basis, which is really just the strength of the justificatory tale.

Truth has little to do with justifications. Knowledge stands apart from mere belief when it does something – when it proves itself reliable. Reliability, like an onion, has no core, and so, knowledge doesn’t have a core either. Peel back a layer and you can aim a cannon. Under the next layer, you have a laser. Under the next, you find the mechanisms needed to build a global positioning system. The same structure undergirds our psychological theory of mind, introspective faculties, and our aesthetics. All those tales which bear re-telling constitute our knowledge.

Truth is just what we’re stuck with.
