De Interpretatione - a treatise on terms and propositions 3. Prior Analytics - a treatise on inference 4. Posterior Analytics - a treatise on logical analysis of science 5. Topics - the method of reasoning to be employed in philosophical questions, when demonstrative proof is not obtainable 6. Sophistical Refutations - an account of fallacious reasonings - as science of how to evaluate arguments and reasoning NOMINAL DEFINITION - the Ancient Greek: λογική, logike - is the use and study of valid reasoning REAL DEFINITION - The study of the principles of reasoning, especially of the structure of propositions as distinguished from their content and of method and validity in deductive reasoning. - “Logic is a science of reasoning”.
