Theoretike

Theoretike is a historical term used to denote the theoretical or theory-focused branch of knowledge. Derived from the Greek theōretikḗ, meaning concerning theory, the term was common in antiquity and later scholastic traditions to distinguish knowledge pursued for its own sake from knowledge oriented toward action or production.

In Aristotle’s lexicon of the sciences, knowledge was divided into three broad kinds: theoretical (theoretike), practical (praktikē), and productive or poietic (poiētikē). The theoretically oriented sciences were those sought for universal truths and explanations, rather than for immediate application. This typically included disciplines such as mathematics, astronomy, physics (natural philosophy), and metaphysics, though the exact placement of some fields shifted across eras and authors. The categorization helped frame debates about method, end goals, and the nature of justification.

Modern usage treats theoretike as an archaic or historical label. Contemporary language prefers terms like theoretical, theoretical philosophy, or theory to describe the same general idea. The older designation remains of interest mainly in studies of the history of science and philosophy, where it helps explain how scholars once organized knowledge into distinct domains with different aims and standards of evidence.

Overall, the concept of the theoretike reflects a longstanding distinction between knowledge pursued for understanding and knowledge pursued for action, a distinction that continues to influence discussions in the philosophy of science, epistemology, and pedagogy.
