Aristotle is history's master of the art of Logic

Classical Logic, in the simplest terms, is the art of Reasoning.

While the faculty of Reason is given to all men at birth, it is a power that must be developed through study and practice.  The art of Reasoning was unknown to men until the art and science or Reasoning, or classical Logic,  was established by the Greek philosopher Aristotle (384-322 BC) in the 4th century before Christ.

The Organon

Aristotle determined that classical Logic consists of six parts and each of these parts was investigated in a separate book.  These books, taken together, formed what was called the “Organon” in Greek, which means “the Method”.

The six books of the Organon were:

  1. Categories:  ideas and words
  2. On Interpretation:  propositions
  3. Prior Analytics: arguments (syllogisms)
  4. Posterior Analytics: demonstrative arguments
  5. Topics: dialectical arguments
  6. Sophistical Elenchi:  false arguments

Logic in the Classical Liberal Arts Academy

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).

  1. Classical Reasoning I: Introduction, Categories, On Interpretation
  2. Classical Reasoning II:  Prior Analytics
  3. Classical Reasoning III:  Posterior Analytics
  4. Classical Reasoning IV:  Topics
  5. Classical Reasoning V:  Sophistical Elenchi

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

God bless your studies,
