LANGER, SUSANNE K (1953)(1967) An Introduction to Symbolic Logic, Dover Publications, New York.
A unit class is a class which only has one member in it. (119). In symbolic logic, class, as in unit class, is not 'individuals in a group.' (119). Class offers no process of collecting individuals. (119). A propositional form might only have a single application. (119). Its variable might only have a single value for a proposition. (119).
A committee of one is a unit class. (120). This is true, even as the committee only has one member. Another author provided example is that of 'corporate sole.' (120). A corporation sole is a legal entity consisting of a single incorporated office. A sole.
Author's propositional example:
(∃x) : x ε A (120).
There exists x: x is/a A.
ε is epsilon from the Greek alphabet meaning is, a. This ε symbol, according to Langer is specifically meant as a symbol for is, a, in contrast with any symbol for is.
The city-states of Greece are used as an example. (121).
x ε city-state of Greece. (121).
The city-states of Greece refers to all members of the class of city-states of Greece. (121). Therefore, it can be propositionally presented as city-state of Greece.
My examples:
A=Athens
S=Sparta
G=City-state of Greece.
A ε G
Athens is a city-state of Greece.
S ε G
Sparta is a city-state of Greece.
Ancient Greece in context.
A ∃ G
Athens exists as a city-state of Greece.
A ∃ G ⊃ S ∃ G
Athens exists as a city-state of Greece the same as Sparta exists as a city-state of Greece.
⊃=Same as.
Theologically, corporate sole is not to be confused with any concept of corporate soul. A human being has one soul (Genesis 2: 7). Those in Jesus Christ, through his death and resurrection and their justification and sanctification, being indwelt with the Holy Spirit. The Holy Spirit would divinely influence and sanctify human beings; the infinite Holy Spirit, influencing and sanctifying the finite human spirit. Demonic possession or harassment would consist of the finite demonic spirit influencing the finite human spirit.
There is not a ontological fusion of soul or spirit as in a finite human soul or spirit becoming divine.
