Science: Toward Unity

Off the University of Chicago's presses last week came two blue-covered pamphlets whose importance to the present and future progress of science and scientific philosophy was belied by their size and price (75 pages and 59 pages; $1 each). The title of the first was Encyclopedia and Unified Science; of the second, Foundations of the Theory of Signs. The two are forerunners of 18 more to be published by August 1939. The first 20 pamphlets, comprising two "volumes," are to be the starting point for other volumes. Editor-in-chief of the project is Otto Neurath.
