- Formal grounds(the basis the statement says VSP uses to reject arguments)
- Rules based purely on the structure and shape of statements, without considering what they actually mean or represent in reality.
- Metaphysical basis(what the statement claims relevant logic is missing)
- A reason based on how reality actually is—the fundamental nature of things that exist, rather than just rules on paper.
- Semantic relevance(what the statement argues VSP fails to capture)
- Whether one statement actually matters to another based on what they really mean—not just whether they use similar words or symbols.
- Syntactic(as used in linguistics)
- Related to the rules and structure of how words are arranged in language, rather than their meaning.
- Topic-overlap(what syntactic analysis can measure)
- When two statements are about the same subject or contain the same basic elements, just looking at their form without considering their actual meaning.
- Variable-sharing condition (VSP)(a specific rule within relevant logic)
- A rule in relevant logic that says: for an argument to be valid, the basic building blocks (variables) in the starting statements must appear somewhere in the ending statement.
- relevant logic(Contrasted with classical monotonic logic where X ⊢ A implies X,Y ⊢ A for any Y)
- A logical system that restricts premise combination so that all premises must bear some relevance to the conclusion; adding irrelevant material does not preserve entailment
- valid inference(Used within informal logic's definition of a good argument)
- A conclusion that follows from the premises
