I was listening to a public radio philosophy podcast on itunes, and it was a short essay by Arthur Shopenhauer. This post reminded me of him. One of the big ideas of his essay was that a human beings biggest problem, besides having to be nullified by eternity, is that we are perpetually becoming without ever being. Time never consumes a single point without having already moved on, forever. Our cells are constantly growing and dying and changing. Our bodies are never the same from one slice of time to the next. He eventually, i think, would argue wiht you that it's impossible for humans to function anyway other than looking into the future, because that's more of a reality than the present is even, because that has already become the past.

Anyways, basic idea... always becoming without ever "BEING".
