The Dialectic and Philanthropic Societies, commonly known as DiPhi or The Societies, are the original collegiate debating societies at the University of North Carolina at Chapel Hill, and together comprise the oldest student organization at the University, as well as the oldest public student organization in the United States. During the academic year, the Societies hold regular meetings at 7:30 PM on Mondays in the Dialectic Chamber at the top of the New West Building. The Societies also hold occasional social events in the Philanthropic Chamber at the top of New East Building. History The Dialectic Society (originally known as the Debating Society) was established in 1795, making DiPhi the oldest student organization at any public university in the United States. They adopted the motto "Virtus et Scientia." The members stated as their goals: "...to promote useful Knowledge..." and "...to cultivate a lasting Friendship with each other..." It is significant that the first order of business for the Debating Society was an order for the purchase of books. Indeed, as the University had no library, the Debating Society's collection became the primary resource for the University, later becoming the core of the school's library. One month after the founding of the Debating Society, the Philanthropic Society (originally known as the Concord Society) split off due to strict rules and political disagreements. It took a new motto, "Virtus, Libertas, et Scientia", with the addition of the word Libertas lending some insight into the reasons for splitting. In 1796 the two societies adopted the Greek equivalents of their names, becoming the Dialectic Society and the Philanthropic Society, known as the Di and the Phi for short. Due to the common use of the shortened form, "Philanthropic" is properly pronounced with a long "i" in the first syllable. In the early days of the University, students were required to join one of the two societies, and the rivalry between the two was extremely bitter. Society members would ride out on horses to greet incoming students, attempting to recruit them and dissuade them from joining the other society. According to legend, this rivalry eventually led to dueling. The university administration eventually intervened and changed the societies' official rules, making membership based upon geography with the Phi members coming from the eastern part of the state and the Di members from the western part (see below for a detailed description of this arrangement).
