The first two pillars in our Liberal Education model, breadth and integration, trace back to the Education model of the Romans. The Romans developed seven subjects, known for centuries as the original seven Liberal Arts, namely arithmetic, geometry, astronomy and music (the quadrivium) and grammar, rhetoric and logic (the trivium). Note the inter-disciplinarity here, with both science (math, physics, logic), arts (music, rhetoric) and the humanities (language, philosophy, logic) - the whole range of the academy! The ancients saw these as all combined and intertwined; for example they connected music to ratios of numbers, and to the motion of planets in space.
Another aspect of breadth and integration that is increasingly important, at all levels of studies, is the idea of multiple viewpoints for looking at the world. Rather than simply learning a standard canon of knowledge, a more modern multi-cultural approach reminds us that although our education system is based on a classical Western tradition, it is important now to unpack and challenge that tradition, to bring in other voices and approaches and worldview, as part of expanding our knowledge and its uses. This means not only welcoming a diverse group of scholars into the conversation, but also making the search for knowledge, the kinds of questions we ask and the kinds of answers we can consider, inclusive and accessible and broad.
