I think I am hitting the nail on the head with this answer.
A partition of a set is a collection of subsets that might be said to "divide the set into pieces". And an empty set occurs when you union 2 sets that have no common elements, Therefore, if they have no common elements they have no subsets, and no sub sets meants no collections of subsets and thus no partitions.
