"The Categories" by Aristotle is a philosophical text from ancient Greece that enumerates all possible kinds of things that can be the subject or predicate of a proposition. This foundational work divides everything in human experience into ten fundamental categories, distinguishing between what can be said "of" versus "in" a subject. Aristotle explores substances, quantities, qualities, and relations, providing a framework for understanding reality that influenced medieval philosophy and sparked centuries of debate about language, logic, and existence.
