Acosmism

Hegel's application of the term acosmism to Spinoza is itself a piece of careful, somewhat mischievous philosophical reclassification: rather than accepting the common eighteenth century charge that Spinoza's system was atheistic, since it identified God with nature and denied a personal deity, Hegel argued the opposite diagnosis fit Spinoza's actual system far better, since if there truly is only one infinite substance and finite things are merely modes with no independent existence of their own, then what has really been denied is not God's reality but the world's, making Spinoza's system, on Hegel's careful reading, acosmism rather than atheism, a position that takes God's reality with maximal seriousness at the direct expense of the finite world's. Some later interpretations of Advaita Vedanta, particularly in modern reformist presentations associated with Swami Vivekananda, push the doctrine of maya in a comparably stark direction, describing the entire phenomenal world of separate persons and objects as having, from the standpoint of ultimate truth, no more genuine reality than a dream has upon waking, a reading more severe than classical Advaita's own more careful formulation of the world as neither simply real nor simply unreal, and one other scholars within the Advaita tradition itself have resisted as an overstatement of Shankara's actual position.

Acosmism functions less as a fully independent tradition in its own right than as the most extreme possible edge that strict monism and strict non-dualism can be pushed toward, which is precisely why it earns a separate entry rather than being folded entirely into monism or into illusionism about the world: the difference is one of degree pressed to its logical limit, illusionism allows the world some functional, provisional reality even while denying it ultimate status, while acosmism, at its strictest, denies the world any reality at all, even a merely apparent or functional one, a distinction that matters enormously for practice, since a tradition holding the milder illusionist view can still meaningfully engage ethical and practical life within the world it regards as less than ultimate, while a tradition pushed to full acosmism has a harder task explaining why engagement with a wholly unreal world should matter at any level. Pantheism stands as acosmism's closest neighbor and sharpest contrast at once, since both deny any reality to God beyond or apart from the totality of what exists, but they reach opposite conclusions about which side of the God-world identity gets to keep its reality, pantheism affirming the world's full reality by identifying it with God, acosmism denying the world's reality by affirming only God's.
