Aristotle’s Organon

In modern circles, we speak casually of the “Scientific Method”, but this was not the original name of this method of investigation. In 1620, Francis Bacon called for the rejection of the “Scholastic Method” that was held by the Catholic Church, and urged modern society to embrace a method he titled the “Novum Organum“.  In Latin, this means “The New Method”. Assumed in this title is the existence of an old or existing method, which was the method of demonstrative investigation developed by Aristotle in the 4th century before Christ.  Aristotle’s “Organon” guided world philosophy and theology for 2,000 years before Bacon called for its rejection.

Aristotle is history's master of the art of Logic
Aristotle (384-322 BC) is history’s master of the art of Logic.

What is the “Organon”?

Aristotle’s “Organon” is the method or instrument to be used by men in the pursuit of philosophical knowledge.  Aristotle teaches this method through six books, which were called “the Organon“, as the 73 books of Sacred Scripture are called the “Bible”.  The books included in the Organon are accessible in our Academy Library:

Studying the Organon

In the Classical Liberal Arts Academy, we study classical Logic through a series of five “Classical Reasoning”  courses.  These courses treat of the six works of the Organon, plus an Introduction to the Categories by a 3rd century philosopher named Porphyry (234-305 AD).

For more information on classical Logic, please see the resources below.  If you have any questions about the study, please contact me.

Online Courses

All of the books of the Organon are studied in our Classical Reasoning Courses. You can study for free (without assessments), enroll in one of our courses (with assessments) or subscribe to our Student Plan (30 day free trial).
