Phi Delta Theta was built on three pillars that haven’t budged an inch since the Fraternity was founded by “The Immortal Six” way back in 1848 at Miami University. The pillars are: The cultivation of friendship among its members, the acquirement individually of a high degree of mental culture, and the attainment personally of a high standard of morality. Shortened, we refer to the principles as friendship, sound learning and rectitude.
