Quick Summary

In logic, an assertoric proposition is a statement that asserts a fact. It is a declaration of the truth or existence of something, or an idea put forth in a discussion. Unlike hypothetical propositions, which deal with logical connections, assertoric propositions are assertions of fact.12

These propositions can be affirmed or denied regarding a subject. The four basic forms of categorical propositions, which are a type of assertoric proposition, are: "Every S is P," "No S is P," "Some S is P," and "Some S is not P".2
