This document outlines the development of logic from ancient times to modern periods. It begins with Nyaya philosophy in India, then covers pre-Aristotelian thinkers who engaged in argumentation. Aristotle is noted for developing syllogistic logic. Subsequent periods expanded on Aristotelian ideas through additions like hypothetical syllogisms. Modern logic revived with symbolic notation and connections to mathematics through thinkers like Leibniz, Frege, Russell and Whitehead. Formal logic systems were then established in the 20th century.
