Book excerpt: The reference to 'questing unity" pertains to many different subjects and themes involving grappling with issues in such areas as comparative literature, linguistics, literature, history and mythology. In all events every comparison implies a criterion wide enough to comprehend the scope of the common area occupied by the subjects of comparison, whether the inquirer is aware f it or not. Thus comparison involves delving into one's own psyche, or not? Without the assumption of a universal underlying unity: no religion, no science and no sanity.
