These are next to each other, and the point, in moving, takes them one by one.
But such a single experience is not what we call a line.

It is but one experience of a line.

Though the experience is not infinitely divisible, the line may be.

This only means that the visual or tactual point of the single experience may stand for, may represent, what is not a mere point but has parts, and is, hence, divisible.

Who can set a limit to such possible substitutions?
in other words, who can set a limit to the divisibility of a _real line_?
It is only when we confuse the single experience with the real line that we fall into absurdities.
