Good, natural, attainable

What is good or bad, or what is desirable, is a complicated, human, concept. In terms of ontological status (inexistent), origin (human processes ranging from biological to cultural), weaknesses (political), or relevancy (the human condition). It tentacles spread out to most of human endeavor, and it is likewise rooted throughout.

What is natural, is the determination of the affordability of things, changes, processes. The natural quality is disconnected entirely from the concept of good or bad, in the sense that its characteristic is to be described, and in itself makes no reference to human ethics, will, esthetics, politics, or any other human endeavor. This is not to say that descriptions of natural things may not make reference to human concept, in fact the study of humankind leads directly to various fields of natural study. It is to say that the natural is not influenced by human thought.

Or, well, obviously it is, in action. Yet we will try to characterize this nevertheless obviously present, yet somewhat mysterious, distinction between the natural and the desirable.

In so far as this distinction exists (and it will be an existential threat whether this is the case), it must have to do with (free) will. Or, the distinctly human quality of deciding to go against the natural flow. Compound constructs showcasing this tendency involve such things as "human dignity", or the "ethical".

Described in this way, we could even settle now, with a technical and reductionist definition of the good, as, such things that were brought about by humans which, on that face of it, are unnatural. Their naturality, of course, is exemplified by their repeated occurrence, their codification in human concepts. However, they are unlikely, and with technical words like entropy they can probably be described pretty well.

We would however, end up with a very dissatisfying, empty equation between the human and the good. (Don't we?)

Habermas brought in a viewpoint that I like: he equated "good" not just with anything human, but specifically with something like "open-ended results of inclusive and shiftable communication".
