Yes, but, not only aren't numbers what you can see (or even "see"), but
they don't constitute lines either. The one-one correspondence between
numbers and points on a line is a postulate of the arithmetization of
Euclidean (for example) geometry. In finite geometries and non-metric
geometries there is no such one-one correspondence.

Do, as a concession to my poor wits, Lord Darlington, just explain
to me what you really mean.
