Categories. On Interpretation

Aristotle (384-322 BC) — one of the greatest thinkers of Antiquity, a student of Plato and mentor of Alexander the Great, the founder of the Peripatetic school, the creator of formal logic, a natural scientist who significantly influenced the development... of all Western philosophy and science.
The first treatise in Aristotle's famous "Organon," a philosophical work dedicated to logic, was "Categories" — one of the earliest works of the philosopher, where 10 categories are first distinguished, which we use to understand and describe the surrounding reality. This work largely served as a foundation for the study of logic throughout the history of Western philosophy.
The collection also includes "Introduction" by Porphyry, an ancient Neoplatonic philosopher, who explains all the main concepts of the doctrine of logic in "Categories," and Aristotle's logical treatise "On Interpretation."
