First, the filter hypothesis implies that consciousness, in its unfiltered state, is unbound. As such, consciousness must be fundamentally unitary and non-individualized, for separateness and individualization entail boundaries. The emergence of multiple, separate and different conscious perspectives, or egos, is a consequence of the filtering and localization process: different egos, entailing different perspectives on space-time, retain awareness of different subsets of all potential subjective experiences, the rest being filtered out. It is the differences across subsets that give each ego its idiosyncratic vantage point, personal history, and sense of personal identity.
