I understand that Bertrand Russell, in repsonse to Zeno's Paradox, uses his concept of motion: an object being at a different time at different places, instead of the "from-to" notion of motion.
I also understand that this concept solves Zeno's Paradox of the arrow, as his concept aptly describes the motion of the arrow; however, his concept of motion does not aptly resolve Zeno's Paradox when told as the "dichotomy" and the "race". However, I don't understand the following quote:
But it is not essential to the existence of a collection, or even to knowledge and reasoning concerning it, that we should be able to pass its terms in review one by one.
Can someone explain why this addition to his notion of motion not fully account for the "race" and the "dichotomy"?
