Any philosophy that just asserted that the Universe has meaning was a non-starter, for me. There is nothing that I can see that unambiguously tells me that the Universe ultimately has absolute purpose or meaning. It could, but anyone who tells you they know the fundamental question of why we are here is delusional or a liar. The only overarching framework that could situate me confidently in the world would have to explicitly acknowledge that the Universe could in fact be meaningless.
An English course in college helped me out with this. A lot of the course covered Norse religion and philosophy, which was intensely bleak. Ragnarok, in one version, is the End. There is no rebirth or renewal. The world will be consumed by Fenrir and the chaos wolves, and after, for eternity, the world will be Winter. In that philosophy, this is a fact of life: this future is preordained. Your best outcome is to be invited by the Gods to fight - and lose - in the final battle against the Forces of Chaos and Despair. You're going down, but the highest honor you can bring yourself and your kin is to go down fighting.
Humans create meaning in the face of an uncaring, indifferent Void. It's our superpower. Human-created meaning is arbitrary, but no less real for that. The fact that Vikings chose to create meaning by slaughtering their unfortunate neighbors is a bit beside the point. That was their interpretation, but it's not the only, nor best one.
Hwæt! The Universe might be meaningless, these nihilistic Viking ghosts whispered to me, across the centuries. Live bravely, do not allow yourself to wallow in despair while entropy gathers itself. Make meaning, fight, build, love, stay healthy right in the face of the Uncaring Void. It's the only thing you can do. Entropy will win. Until then, make it meaningful.
