The Hour-Glass Society was a short lived organization at Princeton University's Graduate College dedicated to the discussion of questions of a philosophical, ethical, or religious nature. The Society held regular sunday evening meetings at which professors or other guest speakers would lecture on a chosen topic. Topics ranged from "the relation of reason to faith" to "what is sin?"
