Characteristic 6. Here, I emphasize that it is not one quantitative continuum but the change in direction that indicates accumulations of infinitely many quantities. One quantitative continuum is the manifestation of the change in direction. Two features are included in this quantitative continuum. First, the continuum exists as a unity where its any parts is itself and its any parts cannot be segmented into fewer parts or larger parts. As a specific example, the circumference of a circle cannot be selected as parts that are different from the other parts. Second, the change in direction indicates the infinitely great, which means that any parts of this continuum are infinitely great.
