Just like many of our assertions about the world are instances of Universal Affirmative or Universal Negative propositions, we also make many assertions that are instances of Particular Affirmative or Particular Negative propositions. Getting a sense of how these propositions function and relate to one another helps us understand what exactly it is that we’re saying about the world around us. Furthermore, diagramming them will help us to visualize what we really mean and don’t mean when we make such claims.
