AI Research on Objects (Material Things) - Dictionary of Arguments

Norvig I 449
Objects/AI research/Norvig/Russell: Physical objects can be viewed as generalized events, in the sense that a physical object is a chunk of space–time. For example, USA can be thought of as an event that began in, say, 1776 as a union of 13 states and is still in progress today as a union of 50. We can describe the changing properties of USA using state fluents, such as Population(USA). A property of the USA that changes every four or eight years, barring mishaps, is its president. One might propose that president(USA) is a logical term that denotes a different object at different times. Unfortunately, this is not possible, because a term denotes exactly one object in a given model structure. (The term President(USA, t) can denote different objects, depending on the value of t, but our ontology keeps time indices separate from fluents.) ((s) Cf. >Four dimensionalism/Philosophical theories
).
Norvig I 450
Solution: only possibility is that President(USA) denotes a single object that consists of different people at different times.
