Moreover, it would be absurd for people to be led astray by Zeno's arguments, and to be persuaded because they cannot refute it to invent indivisible lines; and yet because of the movement of a straight line to make a semicircle, which must touch infinitely many arcs and distances in between, and because of its movement to form a circle, which readily shows that it must move at every point if it moves to make a semicircle, and because of other similar considerations about lines to refuse to accept that a movement can be generated such that in it the moving thing does not fall successfully on each of the intervening points before reaching the end point.
