We humans replace the bulk of both our "hardware” (e. g., our cells) and our "software” (e. g., our memories) many times in our life span. Nonetheless, we perceive ourselves as stable and permanent. Likewise, we perceive objects other than ourselves as permanent. Or rather, what we perceive as objects are those aspects of the world that display a certain permanence. For instance, when observing the ocean, we perceive the moving waves as objects because they display a certain permanence, even though the water itself is only bobbing up and down. Similarly (...) we perceive only those aspects of the world that are fairly stable against quantum decoherence. (Max Tegmark)
