- The Present either has no duration, or it has duration.
- The Present has duration if and only if Chronons exist.
- Chronons do not exist.
- The Present has no duration.
- If the Present has no duration, then no two things can be said to be ‘at the same time’.
- No two things can be said to be ‘at the same time’.
Objection: even if time has no duration, still it is not incoherent to talk about a point in time at which two things simultaneously exist.
Response: A point in time can only exist if time is comprised of points, but that just would be to say that Chronons exist. Ergo, there is still no such thing as ‘at the same point in time’ since some point in time t1 should not be regarded as a point in time if there are no such things (and there are no such things if and only if there are no Chronons).
