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.
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:
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. But in the last figure, when the terms are universally joined to the middle, and both the propositions are categoric, if either of them is necessary, the conclusion also will be necessary. If, however, one of the propositions is privative, but the other categoric; when the privative is necessary, … Read more
1. In the second figure, however, if the privative proposition is necessary, the conclusion also will be necessary; but if the categoric proposition is necessary, the conclusion will not be necessary. 2. For, in the first place, let the primitive proposition be necessary, and let it not be possible for … Read more
1. It also sometimes happens that one of the propositions being necessary, a necessary syllogism will be produced, yet not of either proposition casually, but of that which contains the greater extreme. 2. For instance, if A is assumed to be present or not present with B from necessity; but … Read more
1. Since, however, to exist, to exist from necessity, and to exist contingently, are different; (for many things exist, indeed, yet not from necessity, but other things neither necessarily exist, nor, in short, exists, yet may happen to exist), it is evident, that there will be a different syllogism of … Read more
1. It is likewise manifest, that in all the figures, when a syllogism is not produced, both the terms being categoric or privative, and particular, nothing necessary, in short, will be inferred. 2. But if the one is categoric, and the other privative, the privative being universally assumed, a syllogism … Read more
Again, it is also a sophistical place, to bring the opponent to that against which we abound with arguments. But this will sometimes, indeed, be necessary, sometimes will appear to be necessary, and sometimes will neither appear to be, nor will be necessary. It is necessary, therefore, when he who … Read more
The mutation also into a name more known is useful; as, for instance, the clear, instead of the accurate, in opinion; and the love of employment instead of being engaged in various occupations. For when that which is asserted becomes more known, the thesis may be more easily opposed. This … Read more
Again, if anything should be multifariously predicated, but it is posited as inherent, or as not inherent, one of those things which are multifariously predicated must be proved, if both cannot be proved. But this place is to be used in things which are latent. For if it is not … Read more
