"Movement has to happen in the present."
What? How can movement even be conceived without a concept of time? The context from which the above quote was pulled had readers conceiving of an arrow flying through the air, but with time frozen in an infinitude of discrete moments, also called nows. In any given now, motion is inconceivable, but it is only by comparing one now with the next now that movement is perceived.
I agree. Movement indicates velocity. With no movement, velocity is undefined. For the stationary arrow, there is no velocity (not to be confused with zero velocity). Therefore there is no movement and no lack of movement. The paradox is resolved. BTW, I don't think that the Greeks were very good at leaving terms undefined. :)--MathPoet 12:42, 1 October 2007 (UTC)
