Spectra

I want to murderize the term "objective truth".  Because mostly it just means "This is one of my core beliefs".  By scrapping that term, and instead saying "All beliefs are subjective, but some have more evidence in their foundations than others, and this is a difference in degree, not of kind" we can begin to stop fortifying our misconceptions with language. Those things are well-entrenched enough as it is. [...] Fact is whatever is out there in the world, the ding-am-sich. Facts are objective, but you don't have any. Nobody has access to facts. We have beliefs about facts. And those beliefs are formed exclusively from the evidence available to us, as subjects. That evidence can be wrong or misleading. You have no facts. All we have is what you so weaseley call "opinions" (a better word is beliefs). And some beliefs are more well-founded than others. Our most well-founded beliefs, however, are not discernible to us from our core beliefs. They all feel "objective" to us, no way for the individual to know which "objective fact" (actually subjective belief) is strongly held because of evidence, and which is strongly held because of cultural values on happens to hold. So we need to drop that bullshit and start instead lifting our burdens of evidence, even for the stuff our amygdala says is "objective".

Is 1+1=2 a fact?   Of course not, it never was. Maths is an artificial system. 1+1=2 because we define the system so as to give that result. Of course, arithmetic was designed to mimic certain features of reality, but this was done as an abstraction of an abstraction of an abstraction. Each abstraction makes the result less real - but easier to work with. The way we built arithmetic is perfectly analogous to how each child learns arithmetic. First you look at real objects, and produce a theory of kind, then you learn to count real objects, by grouping them in various kinds, abstracting away the individuality of the objects. Then you progress to imagined objects. Then you progress to removing all the remaining remnants of the reality you based it on, working instead with just numbers. -- Andreas Geisler

Incentives

If a bureaucrat (or lawyer) acts on fully specified set of rules and exercises no personal judgement then they can be replaced by a machine. If they don't want to be replaced by a machine they should be able to prove that their personal judgement is indispensable. That changes incentives for bureaucrats in quite a dramatic fashion -- Martin Sustrik

Maintenance

In any operating system whose goal is homeostasis, departures from the current steady stale caused by change in the energy fluxes or their response times will tend to be corrected and a new optimum sought which incorporates the changes. A system as experienced as Gaia is unlikely to be easily disturbed. Nevertheless, we shall have to tread carefully to avoid the cybernetic disasters of runaway positive feedback or of sustained oscillation. If, for example, the methods of climate control which I have postulated were subject to severe perturbation. we might suffer either a planetary fever or the chill of an ice age, or even experience sustained oscillations between these two uncomfortable States.

This could happen if, at some intolerable population density, man had encroached upon Gaia's functional power to such an extent that he disabled her. He would wake up one day to find that he had the permanent lifelong job of planetary maintenance engineer. Gaia would have retreated into the muds, and the ceaseless intricate task of keeping all of the global cycles in balance would be ours. Then at last we should be riding that strange contraption, the 'spaceship Earth'. and whatever tamed and domesticated biosphere remained would indeed be our 'life support system'. -- James Lovelock, Gaia: A New Look at Life on Earth

Focus

An illustration of [the] single-minded corporate focus on financial returns can be seen in a conversation between biologist Paul Ehrlich and a Japanese journalist. Ehrlich observed that the Japanese whaling industry was at risk of exterminating the whales that were the source of its wealth. The journalist responded: “You are thinking of the whaling industry as an organization that is interested in maintaining whales; actually it is better viewed as a huge quantity of [financial] capital attempting to earn the highest possible return. If it can exterminate whales in ten years and make a 15% profit, but it could only make 10% with a sustainable harvest, then it will exterminate them in ten years. After that, the money will be moved to exterminating some other resource.” -- Jeremy Lent, The Patterning Instinct
