The principle of excluded middle is one of the foundational principles of Aristotelian logic, widely employed in modern logic, and present, whether we notice it or not, in our day-to-day reasoning.
In this course, we have covered some of the basic principles of Aristotelian Logic, from his analysis of terms, to his categorical propositions, to his syllogistic logic. Along the way, we touched on topics and methods not mentioned by Aristotle, but those which are immensely helpful in the study of modern logical analysis and interpretation. Ultimately, the totality of logic as we know it has built in some way or another upon many of the core principles of Aristotle.
