Nursery Rhymes

We all appreciate that human individuals progress through stages of cognitive development on the way to adulthood. A toddler is simply not equipped to run a country (hold your quips): the brain hasn’t fully developed. Infants love the game of peek-a-boo precisely because they have not yet cemented the idea of object permanence. Language capability improves over many years—decades, actually. Brains are not “fully” developed until the late twenties (yet assert mastery starting in the teen years).

But, what does “fully” developed mean? It means significant further development in structure or capability is not to be expected. Does it mean that brains reach some theoretical ultimate capability—no more improvements possible—or do they maybe stop short of perfection? Why would evolution produce anything substantially better than what provides sufficient selective advantage in an ecological context, in simultaneous consideration of all other organism attributes and the biodiverse and social environments in which they operate? The tangled difficulty of that sentence barely hints at the immense contextual complexity involved.

So, every last one of us ceases brain development well short of some notional limit. Does that stopping point cross the threshold of being able to master all knowledge or understanding about Life, the Universe, and Everything? Of course not. Evidence abounds. So, we will never comprehend it all, given our limited meat-brains.

All this echoes things I’ve said before. What’s new in this post is what I hope will be a helpful analogy to how adults present ideas to children possessing less-developed brains—thus the Nursery Rhyme title. Since adult human brains also stop short of “full” development, how might we expect our imperfect brains to interact with what we can’t fully understand? We encounter this conundrum all the time in giving “sufficient” accounts to children that are effective, even if they must be over-simplified or distorted to get the point across. So, how would a hypothetical species possessing far more wisdom explain the incomprehensible to us, as if we were children to them?

Decisions, Decisions

Which way will the coin decide to land? Image by ICMA Photos.

In my continuing pursuit of humility as an antidote to modernity’s human supremacy illness, the atoms that constitute who I am take issue with lofty and self-aggrandizing concepts of idealism, dualism, and free will—replaced by the unflattering material world and its staggering wealth of emergent complexity. I have argued that opposite of lacking imagination and being reductionist, such a view far exceeds our imaginative capacity and is in fact rather expansive and open-ended next to facile short-cut cop-outs that sweep mind-boggling complexity under the rug by pretending that constructs like mind, consciousness, soul, God, or Santa Claus are real.

One stubborn sticking point is the beguiling illusion that “we” are separate from “our” corporeal bodies, owning and controlling them, somehow. This notion is prevalent, despite zero evidence that we are anything but corporeal, and heaps of evidence to the contrary. A less supremacist variant allows that all life, down to microbes, are endowed with this material override to exert control and autonomy over their environments, but still demand a line of separation between life and inanimate collections of matter. An amoeba suddenly changing course in reaction to its environment is, in this view, ontologically different than a hurricane changing course in reaction to its environment.

Granted, life is amazing and exhibits unambiguous behavioral differences compared to, say, rocks (hint: check the complexity of internal structure). A materialist, mechanistic basis does not in any way diminish life, although that’s often the regrettable reaction from someone who takes it on faith that transcendent mystery accounts for life’s splendor—rather than intuition-busting eons of emergent material fabulousness. Well, it turns out that life is incredible no matter what inconsequential thoughts we form about it. In any case, the point that I will develop in this post is that “decisions” are carried out at every level from electrons to ants, but are at no point fundamentally operating on a different basis.

Depending on how one defines “decisions,” either electrons and bats carry them out by the same rules, or neither can be said to be making “free” decisions. Whatever the case, electrons and bats are on similar footing when it comes to “decisions,” albeit at vastly different scales of complexity. Given enough information and background, the decisions by either are not surprising, even if not precisely predictable. Now, I do identify a difference between living decisions and inanimate decisions, importantly, but it’s a subtle one that I’ll wind my way toward.
