Why “Entering Another World” Fails: A Structural Analysis and a Generative Alternative

This paper establishes a structural determination of the notion of “entering another world.” Under the constraint that the self cannot exist as two, three approaches are analyzed: full entry, extended sensory–action coupling, and dual occupation across domains. It is shown that full entry entails the loss of the original self, extended coupling leads to inner–outer mixing and eventual subsumption, and dual occupation results in instability and collapse. Thus, entry as such is rejected. An alternative is proposed: rather than entering, a host-body is constructed within the target world, a self-manifesting proxy is generated, and structural continuation is achieved. In this way, the problem of crossing worlds is reformulated as a problem of generation. The framework unifies problems such as consciousness transfer, virtual and augmented reality, and brain–computer interfaces under a single structural account.
