The three fundamental building blocks of Aristotelian logic are terms, propositions, and syllogisms. Each of these has its own function and specific set of properties. In this lesson, we looked at syllogisms. By putting together what we’ve learned about terms and propositions, we have finally gathered an understanding of this form of argument. As we have seen, they can be either valid, or sound. Using the properties we have learned, we can now characterize certain arguments and their specific components from a logical perspective. In the following lessons, we will nuance our understanding of each building block as matters become more and more complex.
