I've said this before, almost in these exact words, I'm sure, but a thing being finite, brief, limited, isn't what gives it value--those are secondary, unrelated traits. Progress can exist above a zero-limit (at perfection), without needing to be reset. A broken leg now healed "adds" to a person's life not from its brokenness but because of its being cared-for. A sunset is beautiful because it's beautiful: this beauty is found in its appearance (its colors, its brightness, the contrast between the rim of the sky and the darkness above, and how this combines with our ability to perceive the dimension of aesthetic beauty), and it would stay beautiful if you captured it in a photograph or painting. If you visited a planet whereupon the sunset was permanent, it would be beautiful there, too (it gets like that a few days a year around the polls at each of their high summers on our own planet. They are just as beautiful even while they last longer. We call it a "sunSET" in our language but it's just the state of the sun being angled near a given horizon.) It's human folly to conflate the bad bits with the good, to say that a thing's brevity, even though unrelated, somehow "gives" it its other traits. You're human, you have a brain--you know how to dissect these elements, separating good from bad. Otherwise, nobody would've ever made antidote or blood pressure medicine from venom. Some good things can exist independently. It's your job as a creature with a brain sophisticated enough to develop a sense of ethics whether or not it wants to to find them. It gets old when even old people praise such sentiments for their "wisdom"--a thing isn't beautiful because it can die. What are you talking about. Think further.
