Home » Trivium: The Art of Logic 2023

On 1 May 2023, we will begin our second Trivium course of the year: The Art of Logic. Our first discussion session will take place on 8 May 2023 at 6:00pm ET. This course is open to all enrolled Lyceum Institute members; having taken Grammar is not a prerequisite. If you would like to sign-up and take this course, enroll here. You can find out more about our approach to studying logic here.

In brief, however: is there right reasoning concerning reasoning itself? Can we reason rightly about other things if we are misled as to the nature of reasoning itself? Of course we can; but incidentally, rather than properly, and in a manner not precisely under our own control. Without having successfully undergone training in logic, we are much more likely to go awry in the formation of our beliefs—holding things untrue or unfitting to reason, that is—than otherwise. Thus, even though it is quite difficult, Thomas Aquinas rightly says that we ought to begin our learning from logic:

And for this reason it is necessary in learning to begin from logic, not because it is easier than the other sciences—indeed, it has the greatest difficulty, since it concerns second intentions—but because the other sciences depend upon it, insofar as it teaches the mode of proceeding in all the other sciences.

c.1257-59: In de trin., q.6, a.1, p.2, ad.3: “Et hac ratione oportet in addiscendo a logica incipere, non quia ipsa sit facilior ceteris scientiis, habet enim maximam difficultatem, cum sit de secundo intellectis, sed quia alia scientiae ab ipsa dependent, in quantum ipsa docet modum procedendi in omnibus scientiis.”

In our course, we will concern ourselves not only with learning to analyze propositions and syllogisms of both categorical and hypothetical structure, to parse prose writing for its logical structure (and errors therein), and to illuminate the illative relation which ties together all our reasoning, but also situate logic both historically and as it fits within the broader tradition of the Trivium.

Again, this seminar is open to all Lyceum Institute members, at every level of enrollment. Our primary (required) textbook is R.E. Houser’s Logic as a Liberal Art.
