Acosmism, in contrast to pantheism, denies the reality of the universe, seeing it as ultimately illusory, (the prefix "a-"in Greek meaning negation; like "un-"in English), and only the infinite unmanifest Absolute as real.

1. In certain philosophical systems, acosmism suggests that only the absolute, or God, truly exists.
   在某些哲學體系中，無宇宙論認為只有絕對存在或神是真實存在的。
2. The concept of acosmism challenges the perception of material reality.
   無宇宙論的概念挑戰(zhàn)了對物質(zhì)現(xiàn)實的認知。
