A second, quite different response is modeled on Armstrong’s view that “instantiation” is a “tie,” not a relation (since “the thisness and nature are incapable of existing apart”), and, hence, it is not subject to a relation regress. (1978, 109). The idea is that the union of compresent tropes is too intimate to speak of a relation between them since the tropes of the same object could not have existed apart from each other. This response, however, requires more than generic dependencies—for example, that this specific mass trope requires the existence of some solidity trope or other—since generic dependencies would not guarantee that the specific mass and solidity tropes, say, in this particular bundle could not have existed without being compresent.
