The set of truth values may be regarded as forming another such subdomain, namely the one of logical values, and logic as a branch of science rests essentially on this logical domain and on exploring its features and regularities.
The approach to language analysis developed by Frege rests essentially on the idea of a strict discrimination between two main kinds of expressions: proper names (singular terms) and functional expressions.
However, as McNamara (1993) demonstrates, the argument rests essentially on the principle that necessarily equivalent SOAs are identical, a principle clearly at odds with the fine-grainedness of SOAs that Plantinga assumes elsewhere (and often) in various applications of his theory.
His concept of time rests in fact essentially on a broad notion of succession, which allows him on one hand to retain the unity of the concept of time, but, on the other hand, to acknowledge the existence of different temporal forms (Trifogli 1990b).
