Study Notes

Nature of a Proposition

A proposition is a declarative statement with the potential to be true or false.
Examples of propositions include "Eze is tall," "No women are decent persons," and "All men are mortals."
Statements that are questions, exclamations, commands, or interrogations do not qualify as propositions.

Types of Proposition

Simple (Atomic) Proposition: Contains a single piece of information and cannot be divided further. Example: "All logicians are intelligent persons."
Compound (Molecular) Proposition: Composed of two or more simple propositions. Example: "Bola and Jide are coming," which can be split into "Bola is coming" and "Jide is coming."

Components of a Proposition

Subject Term: The main focus of a proposition, represented by the subject noun. Example: In "John is tall," "John" is the subject term.
Predicate Term: Describes or qualifies the subject term, providing additional information. Example: In the same proposition, "tall" is the predicate term as it describes John’s height.
Copula: The word that connects the subject and predicate terms. Example: In "John is tall," the copula is "is," linking "John" to "tall."
