Our Logo

In 152 BC, the Stoic Crates of Mallus constructed the earliest known globe of Earth. In the First Century, Epictetus located human good and evil within each person's "sphere of choice" (Discourses 1.4.2, 27; 2.16.1). The logo for the Stoic School represents Crates' globe as well as Epictetus' sphere. The straight lines in the middle divide the sphere into four sections representing the four cardinal virtues that make up one Virtue. Our logo is a symbol of global good through virtuous choices.
