"A school of ingenious Bible-twisters arose, . . . in order that people who no longer believed could continue with good conscience to collect the salaries of belief." ―Upton Sinclair, Mammonart Mammonart: An Essay in Economic Interpretation (1925) by Upton Sinclair consists mainly of critiques of many great artists from Homer to Mark Twain and from Michelangelo to Jack London. It is one in a series of six books the author wrote analyzing American institutions from a socialist perspective. Other books in this muckraking Dead-Hand collection, include: The Profits of Religion (religion, 1917), The Brass Check (journalism, 1919), The Goose-Step (higher education, 1923), The Goslings (education, 1924), and Money Writes! (literature, 1927), all available from Cosimo Classics.
