universal affirmative
C1/C2Technical, Formal, Academic
Definition
Meaning
A proposition or statement in logic which asserts that a certain property holds for all members of a given class (e.g., 'All S are P').
In traditional Aristotelian logic, one of the four standard forms of categorical proposition, characterized by being universal in quantity ('all') and affirmative in quality (asserting inclusion). It can also be used more loosely to describe any sweeping, all-encompassing positive assertion.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'универсальное подтверждение'. The correct logical term is 'общеутвердительное высказывание' or 'общеутвердительное суждение'.
Common Mistakes
- Confusing it with a 'universal negative' (e.g., 'No S are P').
- Using it colloquially to mean 'a widely accepted truth' rather than its strict logical form.
- Misidentifying statements like 'Most dogs are friendly' as universal affirmative (it's particular).

FAQ
Frequently Asked Questions
Yes, 'Every S is P' is logically equivalent to 'All S are P' and is considered a universal affirmative.
In traditional Aristotelian logic, no, as it assumes the subject class has members. In modern predicate logic, such a statement ('All unicorns are magical') is often considered vacuously true.
Logically, its direct opposite is the 'particular negative' (Some S are not P), which is its contradictory. Its contrary is the 'universal negative' (No S are P).
You might encounter it in texts on rhetoric, law (interpreting statutes), computer science (database queries with universal quantifiers), or linguistics (semantic analysis).
