What really puzzles me though is that sometimes Tony is quite happy to
answer what the state of things is at noon, even while he denies at the
same time that noon "exists". Or perhaps sometimes he'll say that noon
only "exists" if we "allow infinite iterations"; as if somehow the
insertion of balls into the vase is what causes the clock to move
forwards.
