Pi and Sigma are the Greek counterparts of the letters "P" and "S." For Brother Sigmans in the Fraternity, Pi Sigma has two meanings: Paglingkuran ang Sambayanan (Serve the People) and Paragon of Scholarship.

It has been said that idealism springs from deprivation and need. It is within this context why the Pi Sigma Fraternity was born. Conceived on the thought of nationalism, the Fraternity realized this into its principles, Paglingkuran ang Sambayan and Paragon of Scholarship.

Paglingkuran ang Sambayan (Serve the People) embodies the rationale of the Fraternity. The sambayanan are the masses which comprise more than 70% of the total population. They are the oppressed. They are the trodden. And they are the majority. They are those who realize the dreams of wealth and power yet denied of their just share. The principle recognizes the fact that although the masses are the vital cogs in national development, they have been treated on the contrary. It is the tradition, the role and the goal of the Fraternity to forward the needs, struggles and the sentiments of the masses.

Paragon of Scholarship emphasizes excellence in all fields of endeavor and the pursuit of a nationalist, scientific and mass-oriented education. It also embodies the emphatic belief that education should not be limited within the four walls of the classroom. Education is learning from the masses with the masses. With service to the people, it is envisioned to develop the fraternal brothers into nationalists.

The struggle for a better educational system and culture is part of the Fraternity's vision for a truly sovereign, democratic, and prosperous Philippines, a vision long conceptualized and pursued by its founders and alumni, and continues to be a guide for the present generation.

It sets the Fraternity's position on major issues confronting our nation. It calls for an end to foreign domination on our internal affairs. It has sided with the farmers' organizations in its demand for a genuine agrarian reform, and the workers for better working conditions and higher wages. In general, it has staked itself with the oppressed majority in framing a society free from exploitation and domination, and conducive for collective advancement and development.

As such, the Pi Sigma Fraternity is a nationalist, mass-oriented and a democratic Fraternity.

The idealism and perseverance of the Fraternity's founders have brought the Pi Sigma Fraternity to where it belongs now, a national organization potentially strong in nation building.

Why the Greek Letters?

It has been a tradition among students to look up to Greek-lettered organizations and brotherhoods as prestigious groups. This could be because we look after the Greeks as a learned people, for what emanated from them are the numerous things that we now know --- ranging from the arts, the sciences, politics, etc.

The Pi Sigma Fraternity, however, does not ride on this notion to promote only itself, as it attempts to inject new blood into Fraternity trends.

With its nationalist, mass-oriented and democratic character --- calling not only on all Sigmans but others to serve the best interest of the people and be paragons in this endeavor ---, the Pi Sigma Fraternity has elevated prestige among Greek-lettered organizations. It equates prestige for itself to the noble cause of defending and fighting for the democratic rights of the oppressed masses.

To be a prestigious Sigman, one should be committed to his covenant of Paglingkuran ang Sambayan and be a Paragon of Scholarship.
