Lecture XVIII

optics has to be fed in the first instance, and continually verified later, by facts experienced by seeing persons; so the science of religions would depend for its original material on facts of personal experience, and would have to square itself with personal experience through all its critical reconstructions. It could never get away from concrete life, or work in a conceptual vacuum. It would forever have to confess, as every science confesses, that the subtlety of nature flies beyond it, and that its formulas are but approximations. Philosophy lives in words, but truth and fact well up into our lives in ways that exceed verbal formulation. There is in the living act of perception always something that glimmers and twinkles and will not be caught, and for which reflection comes too late. No one knows this as well as the philosopher. He must fire his volley of new vocables out of his conceptual shotgun, for his profession condemns him to this industry, but he secretly knows the hollowness and irrelevancy. His formulas are like stereoscopic or kinetoscopic photographs seen outside the instrument; they lack the depth, the motion, the vitality. In the religious sphere, in particular, belief that formulas are true can never wholly take the place of personal experience.
