Meanings, Symbols, Insignia, Colors

Philosophy‘Phi Sigma Tau’ stands for “Of  Those Who Love Wisdom.”

The Society’s emblem is a pentagon. Each of the five angles displays a symbol that represents one of the great “streams of world thought”: Chinese, Indian, Islamic, Hebrew, and Greek.  

The Seal of the Society is the reverse side of the Athenian silver tetradrachma, bearing an owl, olive spray, and small crescent. The margin of the Seal bears the legend Phi Sigma Tau, 1930.

The colors of The Muhlenberg chapter are “madonna blue” and white, symbolizing purity and integrity – virtues of the true philosopher. 

The White Rose is our flower, symbolizing the beauty of Philosophy, “fairest of all disciplines.” 


Membership in the Muhlenberg chapter is based on invitation by the Department faculty, usually during the Senior year. Students eligible for membership are those who have met the Department’s highest standards of excellence. A one-time fee is paid to the National Society for membership documents and official registration. Participation in the Muhlenberg Department’s initiation ceremony and attendance at the dinner immediately following the ceremony are optional. Our ceremony incorporates elements of the original Alpha Kappa Alpha initiation and is, thus, unique.
