However, I have come to believe that all of the basic components of diagramming can be effectively translated into propositional logic. Nevertheless, I think diagramming is an important supplement to logic, because it provides a streamlined way of mapping long and complex arguments that would be very difficult to map with horseshoes and wedges. In this section, I will be making connections between diagramming and…
