Usually the improvements we imagine have negative consequences to the whole.
If, for example, you remove those exploding stars, there would be nothing past the basic elements, and no earth and no us. We're composed of the result of past violent massive explosions.
If we remove mutations that result in all manner of disease, we remove the engine of speciation and all the positive results of "good" mutation. If we remove pain, we remove key information for survival. If we remove the capacity for evil, we remove the capacity for good.
It's all a package deal, the way the world works; remove a piece and the whole doesn't work, we end up with chaotic nothing. Opposites are part of the whole, both are necessary for anything to come into existence.
Humans still have the option to opt out of the who system.
Still the default for humanity is compassion. While evil and lies and ugliness exist, goodness, truth and beauty are favored by the cosmos.
The alternative is random nothingness, I can imagine that. But it would not be the best of possible world, it would mean no world possible.
You asked me if I could imagine and I said yes, but not sure if possible. I can design a perfect optical system that cannot be made for practical reasons.
God doesn't have those limitations. Why design a uvula? Or an appendix, or a crossed respiratory and alimentary tract?
Why not design self-healing bodies? Bodies that grow severed limbs the way we grow hair and nails, or the way a lizard grows back his tail? Why not be able to replace bad eyes with new ones, etc?
If we remove the capacity for evil, we remove the capacity for good.
I disagree. Good is absence of evil.
Still the default for humanity is compassion
Compassion is not natural to man. It is learned. What we consider a "human being" is a learned set of values, not an innate characteristic of our animal nature. In other words, it is not our default.
Leave a child in the back yard with only food and water The child will grow up without manners, without a language,with no reading ability, no mathematical skills.
That child will revert to being an animal in no time. In the case of a nuclear or asteroid catastrophe, survived only by 10-year olds or younger, practically all human knowledge will be lost, all knowledge of history, science or any academic field, or anything we consider part of human civilization, would be lost. We would revert to being practically cave men in no time at all.
There is nothing noble about us other than what we have learned. You could say we were domesticated.
The alternative is random nothingness
I don't understand what that means. What is nothingness?
