What is Thomism?  What does it mean, to be a Thomist?  Étienne Gilson once wrote in private correspondence to John Deely, in a letter written in the summer of 1968 that:

‘A thomist’ of whatever brand should find it superfluous to develop a question which Thomas was content to pass over with a few words… [because] it is very difficult to develop such a question with any certitude of doing so along the very line he himself would have followed, had he developed it.  If we develop it in the wrong way, we engage his doctrine in some [new] thoroughfare, instead of keeping it on the threshold his own thought has refused to cross, and which, to him, was still an assured truth.

Étienne Gilson, 28 August 1968 (quoted in Deely 1994: New Beginnings, 36).

This attitude toward being a Thomist, it seems to me, runs directly contrary to the spirit of Thomas Aquinas himself.  There are many problems, difficulties, and issues in our lives to which Thomas’ “few words” provide no guidance in our own endeavors, and yet the resolution of which stands of paramount importance for our intellectual, moral, and cultural well-being.

At the same time, however, Gilson did promote what he and his 20th century contemporary Thomist, Jacques Maritain, called a “Living Thomism” (cf. Gilson 1964: The Spirit of Thomism, 84ff).  In Maritain’s words:

Thomism is not a museum piece.  No doubt, like other systems of medieval philosophy, indeed, philosophic systems of all ages, it must be studied historically… But Thomism [triumphs over time] so more completely than any other [philosophy] since it harmonises and exceeds them all, in a synthesis which transcends all its components.  It is relevant to every epoch.  It answers modern problems, both theoretical and practical.  In face of contemporary aspirations and perplexities, it displays a power to fashion and emancipate the mind.

1934: Preface to Metaphysics, 1.

This emancipative power is not one which resolves the contemporary perplexities by mere repetition of already-stated answers, but one which, in the dialectical manner exemplified by Aquinas himself, weighs and measures the diverse efforts of its time and discerns through or against them what is true in itself.  In this, we see Thomism exhibit a systematic approach to thinking-through honest inquiry while never confining itself to a determinate or closed system of thought.  In this seminar, we will undertake to follow in authentic repetition the Thomistic thinking, in discovering the principles which guide all the inquiries he undertook himself—thereby enabling us not only to follow St. Thomas to his own conclusions, but to seek out conclusions to problems which he himself never had to face.

In this seminar, lasting 8 weeks (with a break at the halfway point—see here for more information on all Lyceum Institute seminars), we will investigate what the principles of Thomistic thinking and how they apply perennially in all ages and to all questions. The instructor for this seminar is Brian Kemple, PhD, Executive Director of the Lyceum Institute. You can read more about Dr. Kemple here.

Lyceum Institute seminar costs are structured on a principle of financial subsidiarity. There are three payment levels, priced according to likely levels of income. If you wish to take a seminar but cannot afford the suggested rate, it is acceptable to sign up at a less-expensive level. The idea is: pay what you can. Those who can pay more, should, so that those who cannot pay as much, need not. Lyceum Institute members receive a further discount (see here for details).
