Return to invariance for the holidays

I had another thought about invariance/variance yesterday as I reflected on some recent experiences. One aspect of life I find entrancing is the rich chaotic activity it seems to be, like an estuary, yet in the constant flux, amid the “buzzing, blooming confusion” we find channels of activity both variant and invariant. Consider again the rendering of the connectome,

remembering that neural structures are only the substrate of much dynamic activity, including electric action potentials, neurochemical messengers and actors, and a plethora of protein action. Recently I have written here about the structures and functions of language, invariant (words, stock phrases, syntactic structuring) and variant (sentences and conversational flow), but there are different and larger invariant structures we all have that shape our personalities.

So consider the tapes that play in our head, the consistent (invariant) worries rational and irrational that occupy our thoughts. Some are fairly adaptive such as goals and motivations (these change adaptively with circumstances) and some less so, inflexible neurotic anxieties that compose our responses to similar situations even though they are out of date and no longer relevant really to what is going on now. And then consider that neurosychiatric disorders might be seen as monolithic stone in an otherwise vibrant landscape, e.g., the depressive thoughts and feelings that stay the same as life goes on and even gets better, or as liquidities of a dissolving mind rendering reality testing rather impractical, e.g., the hallucinatory escapades of a thought disorder. The ancients knew that a healthy life depended upon balance; here I am saying the balance holds functioning from swinging to far towards petrification or diarrhea of mental life. Our patterns of balance and imbalance are multitudinous and vary from culture to culture and from family to family. So this holiday, when one of your family members re-enacts the same old schtick or becomes drunkenly mercurial (even without imbibing), be thankful you have flexible enough balance between variant and invariant processes to see the difference. Travel on.
