Illusionism

Advaita Vedanta's doctrine of maya is easy to caricature as simple denial that the world exists, but its classical formulation is more careful than that: the world is described as anirvacaniya, indescribable as either simply real or simply unreal, because it functions as real within ordinary experience, water genuinely quenches thirst and fire genuinely burns, while failing to be real in the ultimate sense reserved for Brahman alone, since the world's apparent separateness and multiplicity dissolve once the underlying non-dual reality is directly realized, much as a rope mistaken for a snake in dim light is a real perceptual event but not a real snake. Shankara, the tradition's most influential systematizer, argued that avidya, ignorance, is what generates this superimposition, and that liberation consists precisely in seeing through it rather than in changing anything about the world itself.

F.H. Bradley reached a comparably deflationary verdict about ordinary reality from a very different starting point, arguing in Appearance and Reality that relations, space, time, and causation, the basic categories through which the everyday world is organized, are internally contradictory when examined closely, and must therefore belong only to appearance, with a single, harmonious Absolute standing behind them as the only fully coherent reality. Both arguments share a structure that critics find question-begging: each starts by defining full reality so strictly, as strictly self-identical and free of internal contradiction, that the ordinary world can only ever fail to qualify.

Illusionism about the world carries direct practical weight wherever it is held seriously, since if the everyday world is not ultimately real, the rational response is not to chase satisfaction within it but to seek release from mistaking it for what matters, which is exactly the logic behind Advaita's emphasis on renunciation and direct realization over ritual achievement or worldly success.

Buddhism is sometimes classed alongside Advaita here, but the comparison needs care: Buddhist teaching on the impermanence and dependent nature of phenomena is not identical to Advaita's maya doctrine, since Buddhism generally avoids positing any underlying real substance, Brahman or otherwise, that the illusion conceals, making the two positions genuine rivals rather than the same claim in different vocabulary. Realist critics, both religious and secular, press the same practical worry from the opposite side: a doctrine that treats suffering, injustice, and ordinary moral effort as ultimately unreal risks undermining the motivation to address them, a charge Advaita's own tradition has answered in various ways but never fully closed off. Advaita's own defenders reply that the charge gets the practical order backward: it is precisely by seeing through attachment to the transient self and its transient concerns that a life of clear, unselfish ethical action becomes possible at all, rather than a life driven by the very egoic grasping the doctrine of maya diagnoses as the deeper problem.
