 Husserl regards both propositional and nominal meanings as the subject-matter of “pure logic” or “logic in the wide sense”—the study of (i) what distinguishes sense (alias meaning) from nonsense (this part of pure logic being called “pure grammar”) and (ii) which of the senses delivered by pure grammar are logically consistent and which of them are not (this part of pure logic being labelled “logic in the narrow sense”).
