Single Idea 1507

[filed under theme 5. Theory of Logic / L. Paradox / 4. Paradoxes in Logic / a. Achilles paradox ]

Full Idea

Although it is impossible to make contact in a finite time with things that are infinite in quantity, it is possible to do so with things that are infinitely divisible, since the time itself is also infinite in this way.

Gist of Idea

We don't have time for infinite quantity, but we do for infinite divisibility, because time is also divisible
