Nihilitarianism

I think the idea of infinitarianism arose as a synthesis of Eastern and Western philosophies, in particular Zen and existentialism, the latter having roots in cynicism and romanticism, and the former in Daoism and Buddhism. They have a lot in common: ziran is equivalent to authenticity, samsara equivalent to eternal return, the thing-in-itself to suchness.
They have the same goal, to be free, but through opposite approaches, yin and yang, rational and intuitive, one derived from the Christian focus on light, the other derived from the Buddhist focus on emptiness. Existentialism seeks to recreate the self as one desires by being responsible for one's own choices, Zen seeks to transcend the self entirely by detaching from one's desire into a choiceless awareness.
So how can these be combined? Well, in infinitarianism desire and detachment aren't mutually exclusive (because nothing is): desires can still exist when we are not attached to them, but we're watching them from a distance where we can keep a perspective on all else we desire, so that one desire doesn't thwart another. We can act on our free will yet see it as something that we undergo, a force of nature that is our own. We can combine emptiness and light just as there is plenty of both in the universe, and both manifest the other.
