story and sensation is all there is, between the end and the beginning

what is it to be a human? in any instant, all there is are the sensations you feel, see, hear, etc. a temperature, the weight of the earth pushing against your feet or arse, your shirt label on your neck. and then there is the story you tell yourself these things mean. but you know, you could be a brain in a vat being fed false experiences by a computer. and you are free to tell yourself that story if you prefer it.
