  The first suggestion would normally be rejected as clearly false, but there will come a point along the spectrum illustrated by (i) and (iii) and towards (iii) where the question of whether the hypothesised table would be the same as the one that actually exists have no obvious answer. It seems that the question of whether it ‘really’ is the same one has no clear meaning: it is of, say, 75% the same matter and of 25% different matter; these are the only genuine facts in the case; the question of numerical identity can be decided in any convenient fashion, or left unresolved. There will thus be a penumbra of counterfactual cases where the question of whether two things would be the same is not a matter of fact.
