You See What You Are

“What you see and what you hear depends a great deal on where you are standing. It also depends on what sort of person you are.”

Seven Liberal Arts of Classical Study




In medieval universities, the trivium comprised the three subjects that were taught first: grammar, logic, and rhetoric. The word is a Latin term meaning "the three ways" or "the three roads" forming the foundation of a medieval liberal arts education. This study was preparatory for the quadrivium, which consists of geometry, arithmetic, astronomy, and music. Combining the trivium and quadrivium results in the seven liberal arts of classical study.
