The Nine Greatest Enigmas in Physics, has a chapter on the paradoxes of the philosopher Zeno. These are typified by the one which says if you move towards a destination by having each step cover half the distance, you will never arrive at your destination. This is supposed to show how motion is impossible.
What occurred to me is that what we have here is the difference between the consciousness of man, and one aspect of that consciousness, -- rational thought. What I like about this perspective is that it points to the necessity for complications in man's mental functioning, beyond the the rational, binary, aspect, that part we often call the rational mind. The paradox is less pungent when you realize that the apprehension of motion needs both binary thought and a wider consciousness extant constantly. This wider consciousness, is apparently necessary all the time, for man's comprehension. This is not the majority view of 20th century philosophy, focused as it was on linguistics. The solution to this paradox -- motion is impossible, and yet exists -- was within and about us, all the time.
What Zeno meant, to demonstrate the limitations of rational thought, was a paradox and is now a parable. There are at least two, aspects to consciousness-- that which divides (that is, the rational mind) and that which unifies, unifies human perception, and awareness.
The above paragraphs hardly explain the unity the human mind demonstrates, but hints I hope at the necessity of two necessary dimensions each second that mind is alert. I would not want to suggest that two is a confining condition.
