One of my hobbies is comparing and contrasting apparent synonyms and trying to discern the contours of thought through language usage. This made me want to muddle around in the middle ground between rational and sane. Immediately at hand we have the 'human being' use case; when do we call humans 'rational' and when do we call them 'sane'? Similarly we can ask what sorts of non-human things do we call sane and which do we call rational. Rationality in humans appears to be quite temporal, while sanity moves much more slowly. A person can be rational one second and irrational the next, then 'get over it' thereby becoming rational again. Whereas generally we speak of sanity 'slowly slipping away'. The outcomes generated also seem to have an effect on which words we use. When the outcomes behind events seem outsized relative to proceedings, we might call the whole thing 'insane'. Whereas 'irrational' seems to refer more to smaller-scoped outcomes, the operative aspect simply being that they're intransigent to ordinary reasoning. As such, 'hypersane' seems to be a similar quality of sanity, and on a continuum you might put 'insane' at the far left, followed by 'irrational' then 'rational', then perhaps 'hyper-rational', followed by 'hypersane'. What does this leave out? Could someone be hypersane and irrational at the same time? I don't think that's the intended understanding of the hypersane concept. In fact, I would venture a definition of hypersane to be someone whose 'irrationalities' are actually expressions of a more universal rationality. When Diogenes did seemingly irrational things, he was really picking up on broader social themes and dynamics and acting in ways that would confound and amaze rather than merely annoy and hinder. Diogenes' self-expressions might be more or less rational at any given time, but that he had a finger on the pulse of ancient Greek culture is undeniable, so he's eminently distinguishable from a 'mere' madman. Whereas someone who is insane's irrational expressions are expressions of individual rationality, hopelessly entangled with the individual's own personal foibles. So what is sanity, if rationalism captures the idea of 'self-expression being intelligible to others'? Even a madman is going to have prescient moments, perhaps they abound in them, as far from the mainstream they are. Perhaps it's the 'capacity of output' that makes up the difference. Terry A. Davis' life, may he rest in peace, was made infinitely better by his masters-level education and programming skills. They gave him a form of agency and ability to fascinate and participate in society that the guy in the red outfit that I pass by frequently on my way to and from work doesn't seem to have.
