Dan: Time… you can’t see it, you can hear it, you can’t weigh it, you can’t… measure it in a laboratory. It is a subjective sense of… becoming, what we… are, in stead of what we were a nanosecond ago, becoming what we will be in another nanosecond. The whole piece of time’s a landscape existing, we form behind us and we move, we move through it… slice by slice.
Linda Murphy: Clocks measure time.
Dan: No, they measure themselves, the objective referee of a clock is another clock.
-The Man from Earth (2007)
Time is a very abstract concept, I have never been able to quantify the time elapsed between the various activities that I undertake on a day to day basis. But that apart, The Man from Earth is a really good movie. Yes, there are some really big plot-holes in the narrative but that only makes it more interesting.
P.S. I have absolutely no concept of time!
