Phi Sigma Tau
From Wikipedia

The Phi Sigma Tau is an international honor society for philosophers. Its essential purpose is to promote ties among philosophy departments in accredited institutions and students in philosophy nationally. In addition to providing a means of awarding distinction to students having high scholarship and interest in philosophy, Phi Sigma Tau also promotes interest in philosophy among the general collegiate public.

The current membership requirements are variable from chapter to chapter, but in general, undergraduate students are eligible for active membership if they have completed two semesters of college, rank in the upper 35% of their class, and have completed at least two semester courses in philosophy with an average overall grade which is greater than the second highest grade of the working scale. The society also inducts graduate students, professors, and non-affiliated personnel. There are currently 151 active chapters in the U.S. and Canada, with 30225 members.


The honor society was founded in 1930 at Muhlenberg College as Alpha Kappa Alpha with chapters in Pennsylvania and Maryland. The society was incorporated as Phi Sigma Tau in 1955 and in 1958 the society was admitted to membership in the Association of College Honor Societies. In 1991 the Society became international with the installation of its first Canadian chapter.


The mission of Phi Sigma Tau is to:

  • To serve as a means of awarding distinction to students having high scholarship and personal interest in philosophy;
  • To promote student interest in research and advanced study in this field;
  • To provide opportunities for the publication of student research papers of merit;
  • To encourage a professional spirit and friendship among those who have displayed marked ability in this field;
  • To popularize interest in philosophy among the general collegiate public.


Chapter membership is open to qualified graduate and undergraduate students, teachers of philosophy, and those who qualify as honorary chapter members.  At the national level, the Society has also established a Laureate Chapter (whose members are distinguished philosophers throughout the world) and a National Alumni Chapter (for graduated PST members who wish to continue their affiliation with the Society).
