You want to divide the world up into opposing absolutes. The world being completely "the bad" is how you can - tragically/heroically - imagine yourself as the entrapped "good". The basic Romantic trope. Liberate me from this constraining world. — apokrisis
I mean, this has been a major topic investigated by existentialists and phenomenologists. Levinas, for example, specifically analyzes transcendence as an attempt to escape.
You keep trying to nudge these phenomenal experiences out of the picture as if they're not important or relevant to the discussion. So what if the world isn't actually divided up into these absolutes? How is that relevant to how we ordinarily approach the world in everyday life (what we might call "nature")?
But of course I can go about things from a different angle. Hypothetically speaking, if you had such godlike powers, would you start life on Earth all over again? Would you try to prevent it from developing? None of your hand-waving now: if you were God, would you do it again? This thought experiment is intentionally made to put phenomenal value back on the drawing board.
But I make the other case. There is no good and bad. There are instead only the complementary limits on being that seek their equilibrium. So at the level of human social being, those complementary limits on free action are the instincts towards competition and co-operation. Living well is doing both in the right way. Hit the balance and life feels great. — apokrisis
First you say there is no good and bad, and then try to recommend a lifestyle of equilibrium (how incredibly novel! wow I never thought about that before...) that inevitably spirals back to hedonic satisfaction. Scienced-up taoism. Sounds great on paper!
So sure, you can trim your sails and tailor your life to equilibrium - until something inevitably disturbs this equilibrium in the form of accidents, pain, disease, aging, and death. You can tune a guitar only so much until the strings just break and the whole thing is fucked.
Schopenhauer1's (and others') point has been the absurdity of being forced to do this to begin with. The environmental and biological system we live in places constraints that, for a self-conscious, time-conscious being like us, can be coercive. Analyzing it objectively and removing any sort of anthropomorphism does not just magically woosh the oppression away, as if this knowledge correlates to calm tranquility in the face of danger. So yes, describing life in the textbook-manner style you prefer can be emotionless and passive, but life is not lived in this textbook-like manner (unless of course you are extraordinarily lucky or just blind). The biologist may recognize that death is the natural and eventual outcome of any biological system, but nevertheless retain a fear of it.
It's also helpful when you happened to get a lucky roll of the die. Far from being determined by reason, lives are dictated by chance and fortune. So you drew a comparatively good lot in life. At least have the decency to recognize when other people didn't and cannot raise themselves up to your unrealistic, dogmatic and coercive expectations.
A population of organisms (not just r-selected) is sustained by an implicit emphasis on the species rather than the individual. Individuality is tolerated only so long as it is beneficial to the survival of the species as as whole. As I'm sure you are aware, human's ability to "transcend the immanent" is an important part of existential and phenomenological analysis. Now that we are capable to reflecting upon our condition and the world at large, we can wonder whether we want to keep going. We can understand that individuality came from social interactions without making the mistake of valuing is less because of it. If we value individuality, and if this individuality puts us into conflict against the wider cosmic entropic "plan", then so be it. Maybe we were meant all along to go extinct. This rhymes well with Zapffe, Freud, Nietzsche and Unamuno's analysis of the tragedy of consciousness. As you said before elsewhere, the mind must find the right "balance" between seeing enough to survive but not too much to be overwhelmed. I'm obviously coming from the perspective that we see too much and that this inevitable disposition is the cause of the majority of our problems.
"Human existence is a penal colony; a sexually transmitted disease; a disappointment; nothing but suffering; “a sky-dive: out of a cunt into the grave”; a one-way ticket to the crematorium. “Nobody gets out of here alive”. Every day is a grim passage, a struggle through moments and hours of loneliness, boredom, emptiness, and self-loathing." — Colin Feltham
The sad thing is that the comparatively optimistic perspective you espouse inherently has to either ignore or forget about those like Mr. Feltham, myself, Schop1, Thorongil, and others who can't seem to figure out how to enjoy life like you seem to be able to. You play by nature's rules and you get to survive. You go rogue or fail to meet expectations and you're purged. And the train keep chugging.
