This Week [5/24-5/29]

First: Summer Seminars are open! 

Science: On Being, Language and Reason, and Cause in Aristotle’s Organon

This seminar treats Aristotle’s methodology for coming to know reality in two parts. In the first part, to be led by Dr. Daniel Wagner, students will gain understanding of the primary terms for defining (Topics), the classification of the most general concepts of the intellect (Categories), and the method of reasoning used for defining beings, which Aristotle calls induction (ἐπαγωγή/epagoge) and division (διαίρεσις/diairesis and ἀνάλῠσις/analusis) (Posterior Analytics). In the second part, to be led by Dr. John Boyer, students will gain understanding of Aristotle’s method of deductive demonstrative reasoning and explanation by proper cause (αἰτία/aitia), which constitutes scientific understanding (Posterior Analytics).

Semiotics: An Introduction

Among the specific goals for the seminar are to understand the general theory of semiotics—as the study of the action of signs—which was founded in Charles Peirce and has since been developed; though we cannot truly grasp this notion of signs unless we first understand the categorical basis of Peirce’s thought, or his “phaneroscopy”; and by grasping this phaneroscopy, along with the general notion of “sign”, we will further pursue the goal of understanding how signs play a role in specifically human thinking.

Thomistic Psychology: World and Passions

Contrary to both [an extreme Stoicism and a libertine Humeanism], the Aristotelian-Thomistic perspective sees in the intellect and human body a hierarchical complementarity, for the passions are a means of receipt and response to the world—and especially the specifically human world—in which we live and by which we pursue our proper ends. Thus, understanding the dynamism of world and passions is essential to understanding the rectitude, and failures, of our passionate dispositions.

5/24 Monday

  • Quaestiones Disputatae – Inquirere (9:30-11am ET).  First of two May Inquirere sessions.  These sessions, lasting anywhere from 30-90 minutes, allow us to work out our questions communally in a live chat.  There are three ways in which someone may participate in an Inquirere session: as an Inquirer, as a Responder, or as an Observer. An Inquirer is seeking to define and develop a question.  A Responder brings updates to their question and works in a live dialectic on what updates have been brought.  Observers listen and comment on the inquiries and responses given.

[2021 Summer] Semiotics: An Introduction

What is a sign?  Though a seemingly simple question, and one which may receive a technically simple answer, attaining a clear understanding of signs is a task both very difficult and very important; so important, in fact, that the whole future of philosophy (and by extension, human knowledge in general) depends upon our getting the answer right.  A great deal of our present difficulty, in the 21st century, follows from several centuries’ failure to attain a true semiotics.  To begin rectifying this, I believe we must draw on a handful of key sources: John Poinsot, Charles Sanders Peirce, and John Deely.  In this seminar, we will focus on Peirce and his unique contributions to the foundations of the discipline of semiotics proper and show how we must instantiate an understanding of signs in our day-to-day practices, both practically and theoretically.

Among the specific goals for the seminar are to understand the general theory of semiotics—as the study of the action of signs—which was founded in Charles Peirce and has since been developed; though we cannot truly grasp this notion of signs unless we first understand the categorical basis of Peirce’s thought, or his “phaneroscopy”; and by grasping this phaneroscopy, along with the general notion of “sign”, we will further pursue the goal of understanding how signs play a role in specifically human thinking.

WHEN: Every SATURDAY from 12 June through 31 July 2021, from 3:00-4:00pm Eastern Time US / 7:00-8:00pm UTC.

And every MONDAY from 14 June through 2 August 2021, from 6:00-6:45pm Eastern Time US.

WHERE: on the Lyceum Institute platform run through Microsoft Teams.

In this seminar, lasting 8 weeks (see here for more information on all Lyceum Institute seminars), we will dive into the most central figure encountered along the Way of Signs—that long-abandoned road which Charles Peirce did so much to clear—and through this journey discover the fullest future of philosophical thinking. The instructor for this seminar is Brian Kemple, PhD, the 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, with discounts for those who are professors and clergy (whose continuing education is not sufficiently prioritized by their institutions) and for students (who are already taxed excessively by the educational system). However, if you are part of the working world and wish to take a seminar but cannot afford the “standard” rate, it is acceptable to sign up at one of these discounted prices. 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).

  • Seminar Discussion Sessions.  Continuing our study of Semiotics: The Tractatus de Signis of John Poinsot (first at 1:00pm ET and again at 8:30pm ET) where we will attend to the notion of relation, in both its secundum esse and secundum dici meanings, as well as all its possible meaningful divisions.  Second, Politics: Postmodern Culture and Politics will look at the counterposition of modernity, through the lens of Thomas Hobbes, whose conception of the rule of law and the state are seen in stark opposition to the Aristotelian-Thomistic position.

Quaestiones Disputatae

We do not, today, know well how to ask a question. Of course, in the superficial sense, we are all well-practiced at asking questions: what is that? What do you mean? Why are you shouting? Where do I go? But these are questions of practical efficacy–not questions about meaning. Most of all, they are not questions which drive at the underlying intelligible causes which truly provide an answer.

This Wednesday we will have our monthly Inquirere session.  Believing that digital technology retrieves the inquisitive spirit of medieval scholasticism, Lyceum Institute members are encouraged to participate in the quaestiones disputatae program. The Inquirere is the intermediate phase of producing a quaestio, in which participants report, give feedback, and seek clarity on their questions and their development.

Spring Seminars Open!

The two spring Seminars are now open.  Discussion sessions will begin on March 20.

[2021 Spring] Politics: Postmodern Culture and Principles

This seminar will explore contemporary political and cultural issues from a classically realist foundation, proposing a genuinely “postmodern” response to the crisis of our time. When the term “postmodern” is used today, it typically denotes what is in practice a kind of “hypermodernism,” that is, an ideology which simply takes modern thinking to its logical conclusion (e.g., complete subjectivism, moral relativism, skepticism, nihilism, etc.). What “postmodern” should signify is something which looks beyond modernity, and it is in this sense which we use the term ourselves. Our “postmodern” response against the modern crisis retrieves from pre-modern political philosophy what modernity wrongfully left behind while engaging directly with modern culture.

[2021 Spring] Semiotics: The Tractatus de Signis of John Poinsot

There are few works which have received less of the attention they deserve than the Cursus Philosophicus of John Poinsot—more commonly known as John of St. Thomas, for his professed fidelity to the teaching of Thomas Aquinas. Within this cursus—a tome spanning 2348 pages—Poinsot addresses logic both formally and materially, as well as many intricacies of natural philosophy pertaining to physics, life, and psychology. But dispersed through these considerations there exists an implicit treatise, one concerned with an element essential to understanding not only topics logical but also natural; namely, the Tractatus de Signis. More information & registration.
