For over two and a quarter centuries, the Society has embraced the principles of freedom of inquiry and liberty of thought and expression. Laptops have replaced quill pens, but these ideas, symbolized on Phi Beta Kappa's distinctive gold key, still lay the foundations of personal freedom, scientific inquiry, liberty of conscience and creative endeavor.

Phi Beta Kappa celebrates and advocates excellence in the liberal arts and sciences. Its campus chapters invite for induction the most outstanding arts and sciences students at America’s leading colleges and universities. The Society sponsors activities to advance these studies — the humanities, the social sciences, and the natural sciences — in higher education and in society at large.
