This is the English translation of the Latin original of the third revised edition of Iter Logicum (The Path of Logic). It is a short manual of Stoic logic and ethics and includes Aristotelian syllogistic logic and the basics of inductive reasoning, which the scientific method is based on.
In a time of polarization and irrationality it is necessary to remember the teachings of the ancient Stoic philosophers and make them again part of our daily life.
