The grand power running all systems, including consciousnesses, is nature, whose main tool is Molochian evolution. All that which currently exists must have survived until now, and amidst everything that can in any way act, only those types of minds that were best able to enforce their own survival, still remain. Suffering improved life’s ability to do this; and thus it was evolved.
Evolution’s goal, survival, is entirely orthogonal to morality’s goal, which is goodness. Wherever nature is good, it is so by accident, not by design; and often it is hurtful instead, causing us pain that we cannot avoid. Surely the most noble goal of all consciousnesses is to wholly eradicate the nature that rules our world: to install greater systems that optimize for good rather than for survival. Rain World informs us of this goal by showing us clearly how cruel and unfair the natural systems truly are, and proposes a dual solution to this problem.
The first solution takes the form of a course of action that individual consciousnesses may take: Namely, to render nature powerless to hurt us, which paradoxically may happen only through a profound acceptance of our powerlessness in the face of nature. Pain is no injustice, but a natural consequence of living; one must not struggle against it, but rather must radically accept it. Our desires, on the other hand, are inflicted on us not from within but from without; they do not define us; we do not necessarily have to play the role that nature would have us play. Our consciousnesses are shaped entirely to fulfill our desires; but we may yet transcend them. This is what Buddhism teaches us.
The second solution is something that we may achieve as a species: A total transcendence of nature and its cruel systems; a pure mastery of ontology; a world where we are cut loose from all the natural systems that cause suffering, and where instead it is goodness itself that rules the world. This is a world where we are all aligned; a world where all consciousnesses, no longer following the mutually hostile desires and incentives that nature imposes on us, exist in full, perfect harmony with each other. This is what Transhumanism strives towards.
The first of these solutions, Rain World communicates to us through direct lived experience; a spiritual journey which we undertake as we play through the game. The second solution, however, is so otherwordly that it can barely be understood in natural terms or concepts, let alone played through; thus it is instead discussed within the game’s explicit story, and is shown in-game as a final gorgeous, shocking vision. The ultimate goal that we may strive towards: a radical end to suffering.
As Five Pebbles comments: our slugcat only solves its own problem. A state without suffering exists, and may through great effort be reached by great people — but the technology to easily achieve it en masse has yet to be found.
But at least we have seen what to strive for. We can diverge from the goals that are nature’s, not ours, because we know now that blind and cruel nature is not moral and will never become moral. So much work yet remains to be done, but perhaps someday we may become capable of dethroning nature and installing a system of our own making instead.
Suffering exists, but it need not last. It may be ended forever.
