Book excerpt: Bernard Lonergan's economic writings span forty years and contain ideas that differ radically from those of his contemporaries. His theory of macroeconomic dynamics was developed through the 1930s and 1940s, culminating in the composition of For a New Political Economy (1942) and An Essay in Circulation Analysis (1944). In Lonergan's Discovery of the Science of Economics, Michael Shute uses archival material in order to examine the influence of Lonergan's early work in methodology, social philosophy, and theology on the development of his economic theory. Shute traces the development of Lonergan's economic ideas from the late 1920s to the publication of his significant economic works in the 1940s. Together with its companion volume, Lonergan's Early Economic Research, this volume outlines the process behind one of the great intellectual discoveries of the twentieth century and uncovers Lonergan's framework for a genuine science of economics.
