A tantalizing part of experience is the noise we don’t experience; both the visual and auditory noise in the environment is immense. The environment is an almost chaos. Light, shapes and sounds; all varied and complex. It is natural to think of shapes as formed, ready made for minds to acquiesce. We see ‘a table’ or ‘chair’ or ‘face’, and that is it. From the chaos we see an ordered world. That is amazing.
Furthermore within the order we can navigate, making sense of the fauna and flora of our environments. There is a degree to which the impressionists had it right however, there is a a sense in which their paintings are closer to the reality of perception than our very own eyes. After all we are closer to light than to objects (physically speaking).
Color perception offers a simple illustration. When we see a series of different colors the colors remain constant despite variability in environmental conditions such as luminance. This is known as color constancy and this is thought to be achieved because the brain reads the ratios of difference between the wavebands of light from one surface to the next. As wavelengths vary between the surfaces we are looking at, the brain ‘reads’ the ratio differences between light from surfaces (which stays the same irrespective of light variations) allowing the colors we see to remain constant. In other words the brain computes color properties from ratios which, when we think about the brain as fleshy stuff is just amazing.
We don’t just perceive and navigate, we order the world too. How many of us, moving into a new home hang up pictures ‘where they belong’? The world is not just a thing we receive, it is something we act on and try to control. Our brains, human brains that is, are immense in their ability to both make inferences from the available data and and then structure the world according to our needs. We are the only species known to use tools to make tools. That too is amazing.
Within evolutionary theory there is a not insignificant idea that the more variable a trait is the less likely it is to have adaptive value. The argument goes that truly adaptive changes quickly loose their variability as the remaining population have acquired them, thus leaving previously adaptive traits fully absorbed by a species; they become a part of the total makeup of the species. Although the assumption has been contested the overarching principle has held as a rule.
The point is that there is a base level at which we all operate on the world with the same bodies. Each an agent coming to the world ready to make something meaningful of it with the same demands. It was Darwin who noticed that across cultures facial reactions to emotions have an invariance. To the extent that we as a species have invariant demands, we too have structured responses. In short, we see and act on a world we see that is, in part at least, not just composed of the world, but of our response to it. In as much as that is the case, the world in which we live is our construction.
For me personally, it is not just that we are conscious that is amazing, it is that we are conscious agents with a bid to our futures. We live in reciprocity with the environment in such a way that the environment serves a function in an almost Hegelian dialectic, but rather than being an historical and transcendental metphysic, the relations are immediate and physical. Rather than being governed by an end point that is teleological in some as yet unperceived way, it is itself evolving between the myriad minds that people the world, somehow finding solutions to life as it emerges. In all its detail, that is magical.
