Comfort makes you weaker. We need some variability, some stressors. Not too much, but just enough.
Never think that lack of variability is stability. Don't confuse lack of volatility with stability, ever.
Never, never, never think - that's one lesson you should have in life. Never think that lack of variability is stability.
When plugged in, the least elaborate computer can be relied on to work to the fullest extent of its capacity. The greatest mind cannot be relied on for the simplest thing; its variability is its superiority.
Scientists tend to focus on what they don't know more than what they do know. And there are a lot of things we still don't know about the climate. But we know the difference between climate variability and climate change, and right now the amount of carbon in the atmosphere is well outside the variability pattern - and that's quite quantifiable.
That the variability of an organism to a certain extent is a constant and certain condition of life we admit, otherwise there would be no distinguishable individuals of a species.
When I wrote a long story about the retreat of sea ice, I made clear it could go the other way for a while, and that doesn't mean we don't know that a warmer world will have less sea ice. It just means there's a lot of variability and people can pay too much attention to the big swings in one direction or the other.
You want to favor systems that benefit from error, disorder, variability and things like that. You want to favor these systems and unfortunately, when - there's something I call the Soviet Illusion. The more the government becomes intrusive, the more things have to follow a script, and it can't handle this kind of system.
If it were not for the great variability among individuals, medicine might as well be a science, not an art.
