The title "King of Logic" is often attributed to **Aristotle**, the ancient Greek philosopher, due to his foundational work in logic and reasoning. His contributions, particularly through works like the *Organon* (a collection of writings on logic), laid the foundation for formal logic that shaped Western philosophical thought for centuries. Aristotle's syllogistic logic remains a central part of the study of logic today.
However, in a more modern sense, **George Boole** could also be considered a "King of Logic," as he developed **Boolean algebra**, a system of logic fundamental to the design of computer systems, programming, and digital circuits, which plays a crucial role in modern computing and electronics.
Both figures are hugely influential in their respective periods, and their works continue to influence how we approach logic today.
