Now that's got me spooked out about how could I know if I'm even the same person moment-to-moment, or what if every blink of the eye or beat of the hard represents a granular moment in time in which a unique conscious entity that has never arisen before nor ever will again flows in and out of existence, like the flame of a candle which continuously renews itself even as the heat and light of one moments dissipates out into empty space the next; with all the memories of the conscious entities that inhabited the space behind my eyes before it, yet with no true ontological continuity between them?
