Which is irrelevant to the conclusion of not being able to traverse the distance.

Again, the conclusion of not being able to travel the distance does not logically follow. It's true that you can divide a distance into (potentially) infinite number of divisions, but that doesn't follow that the finite distance can't be traversed.

A beginningless task, in the Tristram Shandy scenario, is one where he has always been writing throughout the infinite past.


>and when I understand
>what it means for the past to be infinite

A past that is beginningless, consisting of an infinite number of years etc.
