While haecceitistic differences are commonly explained in terms of the distribution of haecceities, haecceitism is not merely the view that haecceities exist. To see why, notice that nominalists who deny the existence of properties might nevertheless accept the modal commitments of haecceitism, claiming that things could have been different non-qualitatively without being different qualitatively. In addition, those who affirm the existence of haecceities and other non-qualitative properties might still go on to reject the distinctive modal commitments of haecceitism (e.g., denying that things could differ non-qualitatively without differing qualitatively). So, although it is common for haecceitists to posit haecceities and employ them in characterizing haecceitistic differences, haecceitism is, in principle, independent of realism about haecceities given haecceitism’s ineliminable modal component.
