Reasoning, while being a part of the Trivium, is one of the four basic branches of Philosophy. It is studied in the library of works, composed by Aristotle, called the Organon. These works include the doctrines of:
3. Demonstrative Reasoning
4. Dialectical Reasoning
5. Sophistical Reasoning
In addition to the systematic works of Aristotle, we also study the dialectical works of Plato along with the commentaries of other wise men.
