"I've seen things you people wouldn't believe. Attack ships on fire off the shoulder of Orion. I watched C-beams glitter in the dark near the Tannhäuser Gate. All those moments will be lost in time, like tears in rain. Time to die."
-Roy Batty, Blade Runner
"The hand that mocked them and the heart that fed:
And on the pedestal these words appear:
'My name is Ozymandias, king of kings:
Look on my works, ye Mighty, and despair!'
Nothing beside remains. Round the decay
Of that colossal wreck, boundless and bare
The lone and level sands stretch far away."
-Percy Bysshe Shelly, Ozymandias
A few bits of (my) philosophy:
1) Existence is suffering. All suffering stems from desires intrinsic to existence. Conflict is part of the nature of existence, and you must learn to face it, and accept that no one will be able to solve all the problems of the world.
2) Existence is inherently absurd. The world is a place where there are some many people doing so many strange and bizarre things that all butterfly into a million different directions, all of which influence you to some extent. All of it is too much for any being to process, and it's this messy interwoven string that makes everything in the universe seemingly random and so improbable that anything could ever happen under any circumstances at all. Trying to derive a greater meaning or purpose that, in any sense is greater or more objective than what one can discern personally, is a futile endeavor, yet is the curse of sapience. As Camus once described, existence is the curse of Sisyphus, except he wears a perpetual smile upon his face.
3) All things are temporary. Nothing lasts forever. The mountains will crumble to ash, the sun will engulf the earth and then fizzle out, and eventually every star in the universe will succumb to death, leaving space an empty void of nothing. But, so is pain, and pleasure and every sensation or feeling you will ever have. Both prosperity and ruin are just as likely to occur, and to then end. It is the fact that everything is limited that gives it value, that those experiences are not constant but that they will fade away. Time is a resource that is infinite, but one only gets such a small sliver to call their own which they must use to construct an empire of dirt.
