The ideals of Sigma Pi, which constitute the underlying reason for the Fraternity's rise, development, and continued existence, are plainly set forth in the Constitution, and are in essence as follows:
- To establish a brotherhood.
- To establish and maintain an aristocracy of learning.
- To raise the standards of morality and develop character.
- To diffuse culture and encourage chivalry.
- To promote the spirit of civic righteousness and quicken the national conscience.
It will be observed that these five objects touch upon three different phases of a man's life: namely, his Contacts, his Concepts, and his Controls.
