||Permissivist conceptions of material objects are those that permit a wide variety of macroscopic objects that, despite being right before our eyes, we do not ordinarily take to exist. For instance, according to universalism, for any given plurality of objects, there is an object that is the sum of those objects. Accordingly, there is a partly metal and partly fleshy object that is the sum of your nose and the Eiffel Tower. According to another form of permissivism (sometimes called “the doctrine of plenitude”), every modal profile that can be instantiated in a region consistently with the empirical facts is instantiated in that region. So for instance, when there is a car in a garage, there is also an “incar”, which is necessarily inside the garage and which will cease to exist if the car leaves the garage. There are two primary motivations for permissivism. The first is that admitting ordinary objects but not extraordinary objects will be intolerably arbitrary. The second is that one who accepts that some pluralities but not others compose a further object will be forced to one or another untenable view about vagueness.
