The cultural role of philosophy is not to deliver the truth but to build the spirit of truth, and this means never to let the inquisitive energy of mind go to sleep, never to stop questioning what appears to be obvious and definitive, always to defy the seemingly intact resources of common sense, always to suspect that there might be "another side" in what we take for granted, and never to allow us to forget that there are questions that lie beyond the legitimate horizon of science and are nonetheless crucially important to the survival of humanity as we know it
