This folder contains correspondence and other documents regarding Edison's opinions and widely publicized statements about immortality, theology, superstition, and related subjects. The two selected items for 1918 relate to a request from author Henry C. Horstmann to reprint a letter by Edison about the structure of matter that had previously appeared in Paul Carus's The Surd of Metaphysics (1903).

Approximately 5 percent of the documents have been selected. Most of the unselected items are unsolicited letters on topics ranging from Christian projects to the protection of soldiers in the war. None of the letters received a substantive reply.
