 A radical option, finally, is to simply opt out of the resemblance game. For if resemblance is out of the picture then, clearly, so is the resemblance regress. One such alternative is provided by Ehring (2011: 175ff). According to him, the trope is not what it is either primitively or because of whatever resemblance relations it stands in to other tropes. Rather, it is what it is because of the natural classes to which it belongs. Although not without its advantages (cf. e.g., fn. 18), a downside of the suggestion is that it seems to turn explanation implausibly on its head. If adopted, tropes do not belong to this or that class because of the nature they have, but have the nature they do because of the classes they belong to. Many find that this is a high price to pay for avoiding the resemblance regress, and the view has few  proponents.[29]
