The Einstein Intersection is a 1967 science fiction novel by Samuel R. Delany. The title is a reference to Einstein's Theory of Relativity connecting to Kurt Gödel's Constructible universe, which is an analogy to science meeting philosophy. Delany's intended title for the book was A Fabulous, Formless Darkness. The protagonist, Lo Lobey, is loosely based on the character of Orpheus. Source: Wikipedia (en)
