Nature is not nature, ever since there are humans, and they think. Earth has been terraformed, made into a garden, a human garden, in the last few million years. By ours truly.
Neanderthals started to used coal (lignite), 80,000 years ago.They also domesticated (that is, modified) European wolves, and invested in real estate, by exterminating Cave Bears.
Thus, following “nature” is a non-linear activity, as, by following nature, we also follow the new nature we deconstructed and rebuilt, that is, we follow ourselves.
The simplest thing is to view all causes as constant. The next simplification is to view them as linear. After that quadratic, cubic, and all powers etc… The exponential, an infinite sum of powers with fast decreasing coefficients, grows as fast, at any point, as its own value. So it’s all over nature.
“Following nature” thus does not just mean hugging trees. It also means dealing with trees the old fashion way: cutting and burning them, to favor plants and animals human beings were involved with (fires in Indonesia are contributing at least one gigaton of carbon to the atmosphere in 2015, making them an appreciable source of CO2). “Following nature” also means using genetic engineering on plants and beasts alike.
Nature has been artificial from even before the rise of civilization. Prehistoric men in Europe already conducted advanced and successful surgeries, from trepanations, to amputations, complete with anesthetics and antibiotics (parts of that knowledge got completely forgotten during the European Middle Ages… to this day!) “Facts” nowadays are all what influences humans, because they, in turn, change nature. Including hopes, systems of mood (“austerity!”, “Islam!”).
The fundamental calculus assigned to (say) Stoics, is the fundamental calculus of humanity. To mostly quote Massimo P’s “New Stoicism, Part IV”:
“physics” (i.e., natural science and metaphysics), “logic” (i.e., logic, epistemology and psychology), and “ethics” (i.e., ethics)… the first two are instrumental to the third one: one cannot decide how to live (the proper domain of ethics) if one doesn’t know how to reason well (logic) and doesn’t also know whatever we can know about the reality of nature (physics). This implies that whenever our understanding of physics changes we need to update our beliefs accordingly, and then examine (via the use of logic) whether and to what extent that also affects our ethics.”
Human evolution discovered, so to speak, this virtuous spiral of understanding and behaving. The species modified itself accordingly, it became that spiral. it is now more energetic than ever.
One cannot read morality straight out of scientific facts, because facts are about the world, and the world is about what we constructed. Thus the calculus of human hope, desire and risk evaluation has to be factored in… And it keeps on changing, the more it reflects on the agitated waters of its darkest soul.
Fundamentally, then, the human species is immensely adaptative (see future Martians): to act, human agents consider human minds, and what their activities wrought (nature). We can call ourselves new names, but our new game is the same as our old game: changing the rules as we see fit, the more we learn, and the more we change nature.
There is no general theory of non-linear mathematics. How could there be? It would be as having a theory of us. Yet we are all about the changes we decide. And how do we decide? This is not an obvious question, it has hounded fundamental physics, ever since the EPR paper of 1935. It is so non-obvious that it is the last loophole to check in the Non-Local aspect of the universe. See the New York Times, October 21, 2015: “Sorry, Einstein. Quantum Study Suggests ‘Spooky Action’ Is Real.”
To quote from there: “the National Science Foundation has financed a group of physicists led by Dr. Kaiser and Alan H. Guth, also at M.I.T., to attempt an experiment that will have a better chance of ensuring the complete independence of the measurement detectors by gathering light from distant objects on different sides of the galaxy next year, and then going a step further by capturing the light from objects known as quasars near the edge of the universe in 2017 and 2018.”
Translation: our presumed influence on the universe is so vast, subtle and pernicious, that quasars apparently receding much faster than the speed of light, are called to the rescue of physicists who want to make sure they reach beyond man, to an unspoiled universe.
We are everywhere we look, at least in our terrestrial neighborhood. Everywhere we reach, human influence has already changed everything. It’s not just about the melting icecaps.
