Final answer:
States-of-affairs can be considered as zero-place analogues of properties and relations in philosophy, similar to how a state function in physics or chemistry represents a system's property dependent only on its current state, not its history.
Step-by-step explanation:
The concept in question relates to the philosophical notion of states-of-affairs which are seen as zero-place analogues to properties and relations. In essence, a state-of-affairs is a specific way things could be at a given moment. It is a factual situation that does not require the application of a property to an object or the relation between objects. In this context, a state function is a property of a system in physics and chemistry which is analogous to this philosophical concept.
A state function is a property that depends only on the current state of a system, and not the path or processes that led to that state. Practical examples include internal energy, enthalpy, or entropy in thermodynamics. This is to say, similar to a state-of-affairs, a state function defines the system irrespective of the path taken to reach that point. The previous trajectory, history, or motion under consideration, whether denoted with a subscript '0' for the initial value or the final value, is the irrelevant part for state functions and by analogy, states-of-affairs.
It can be meaningful to choose the zero of the potential energy function at a convenient location when considering state functions, which aligns with how states-of-affairs are also conceptualized in the absence of any relation to earlier states.
