June 20th. The voice of God and the voice of Nature. I cannot be wrong if I listen to them. Sometimes, when uncertain of a voice from its very loudness, we catch the missing syllable in the echo. In God and Nature we have Voice and Echo. When I hear both, I am assured. My sense of hearing does not betray me twice. I recognize the Voice in the Echo, the Echo makes me certain of the Voice; I listen and I know. Natural Law, Eternal Life, p.238.
