Question

Advantage of predicate logic over propositional logic

Answer 1

For example, "Socrates is a man" is a proposition and might be represented in propositional logic as "S". In predicate logic, we symbolize subject and predicate separately. Logicians often use lowercase letters to symbolize subjects (or objects) and uppercase letter to symbolize predicates.

Answer 2

A proposition has a specific truth value, either true or false. A predicate's truth value depends on the variables' value. Scope analysis is not done in propositional logic. Predicate logic helps analyze the scope of the subject over the predicate
