Gabe Eisenstein earned a Ph.D. in Philosophy from the University of Texas in 1979. He has taught philosophy, including the philosophy of religion, at the University of Oregon, Oregon State University, Willamette University, and Portland State University. He has also had a career as a computer scientist. He is now retired from both careers.

His orientation is thoroughly naturalistic, but he remains interested in religion for its aesthetic, psychological and political dimensions. He says, "It pains me to see so much energy wasted, on both sides of the culture wars, talking about religion primarily in terms of beliefs about the supernatural. My teacher, O.K. Bouwsma, a student of Ludwig Wittgenstein, expressed my attitude toward religion in the title of one of his books: Without Proof or Evidence--because it isn't a question of believing something but of adopting, in each case, a set of attitudes toward the world, much like poetry or art in general."
