THE LIBERAL ARTS
Together, these three arts move you from recognition → reasoning → expression. Grammar gives you the building blocks, Logic gives you the structure, and Rhetoric gives you the power to bring your ideas into the world.
THE WORLD SCIENCES
Together, these four sciences will give you a deep familiarity with numbers. Arithmetic teaches the measure of number, Music reveals number in sound, Geometry shows number in space, and Astronomy displays number in the heavens.
