However, objections may arise in two ways. First, the multiple occupancy view conforms to common sense no more than Parfit’s claim. If we accept the parallel between space and time, while admitting that multiple objects occupy the same space seems to simply not work, then Lewis might need a further demonstration on how multiple objects occupy the same time slice can be possible. Otherwise, this approach to keep personal identity with ordinary intuition might bring about new counterintuitive assumptions. Besides, a more serious problem comes with semantic difficulties. For example, it seems to be implausible to use any personal pronoun to refer to a certain temporal part in a coincident case.
