The main problem for nominalists is to account for our apparent theoretical commitment to types, which, whatever types are, are not spatio-temporal particulars (according to nearly everyone).
According to Johnston, the objects of a subject's hallucination are complexes of sensible qualities and relations that are not instantiated in the scene before him, whereas the objects of veridical perception are spatio-temporal particulars instantiating such complexes.
Perhaps there is no room for indeterminacy in the idealized mereology of space and time as such; but when it comes to the mereology of ordinary spatio-temporal particulars (for instance) the picture looks different.
Nonetheless, precisely this intuitive characterization gives rise to several puzzles that justify philosophical concern, especially with respect to the boundaries of spatio-temporal particulars such as objects and events.
In any case, it is open to actualists (and non actualists as well) to investigate the logic of quantifiers with more robust domains, for example domains excluding possible worlds and other such abstract entities, and containing only the spatio-temporal particulars found in a given world.
The concept of a work of art, she comments, "operates in a rather special way as a universal defined by a spatio-temporal particular, which may itself therefore be regarded as a type-universal" (1958 59, 59).
Analytic narrative is considered " a useful tool for assessing causality in situations where temporal sequencing, particular events, and path dependence must be taken into account" ([ 53] p. 1,164).
In fact, PII(2) and PII(3) are clearly violated in classical physics, where distinct particles of the same kind are typically regarded as indistinguishable in the sense of possessing all intrinsic properties in common and such properties are regarded as non-relational in general and non-spatio-temporal in particular.
In this way the individual mind understands these sensations to demonstrate the presence of a particular object in a particular temporal and spatial location.
Genetic groups also were present during the whole tularemia season from July to September, indicating that no particular temporal patterns were associated with specific bacterial genotypes.
