Full Idea
Every potential infinity seems to suggest an actual infinity - e.g. generating successors suggests they are really all there already; cutting the line suggests that the point where the cut is made is already in place.

A Reaction
Finding a new gambit in chess suggests it was there waiting for us, but we obviously invented chess. Daft.
