Nondualism Versus Solipsism
Nondualism superficially resembles solipsism, but from a nondual perspective solipsism mistakenly fails to consider subjectivity itself. Upon careful examination of the referent of "I," i.e. one's status as a separate observer of the perceptual field, one finds that one must be in as much doubt about it, too, as solipsists are about the existence of other minds and the rest of "the external world." (One way to see this is to consider that, due to the conundrum posed by one's own subjectivity becoming a perceptual object to itself, there is no way to validate one's "self-existence" except through the eyes of others—the independent existence of which is already solipsistically suspect!) Nondualism ultimately suggests that the referent of "I" is in fact an artificial construct (merely the border separating "inner" from "outer," in a sense), the transcendence of which constitutes enlightenment.
