The preceding arguments aim to show that there are no haecceitistic differences of any kind between maximal possibilities. Other arguments are narrower in scope and aim to establish a weaker thesis: that certain kinds of haecceitistic differences are spurious. If successful, these arguments will rule out only some kinds of haecceitistic differences while falling short of providing a perfectly general case against haecceitism. To get a sense of restricted or domain-specific (anti-)haecceitisms, it will be useful to focus on one example where restricted, domain-specific theses of haecceitism or anti-haecceitism play a notable role in a core metaphysical debate.
