 Note that on this test, K things don’t have to be queer in virtue of their K-ness in order to be queer. It could be that they entail the existence of some distinct kind of thing, and that kind would constitute a fundamental addition to our ontology. Perhaps, that is, K things actually don’t fall in the fundamental layer of reality, but they entail the existence of L things, and those are both fundamental and not present in otherwise identical worlds without K things.
