This book is written in the conviction that economics is a powerful tool for analyzing a vast range of legal questions but that most lawyers and law … - Richard Posner

Central to this book is the further assumption that man is a rational utility maximizer in all areas of life, not just in his “economic” affairs, that is, not only when engaged in buying and selling in explicit markets. This idea goes back to Jeremy Bentahm in the eighteenth and early nineteenth century, but received little attention from economists until the work of Gary Becker in th 1950s and 1960s.
The concept of man as a rational maximizer implies that people respond to incentives.(...) From this proposition derive the three fundamental principles of economics.

My reaction to “creative capitalism” as lauded by Bill Gates, Warren Buffett, Michael Kinsley, and (somewhat to my surprise), Professor Glaeser of the Harvard Economics Department is a skeptical one. The embrace of massive corporate charity, the criticism of capitalism by its greatest beneficiaries, and the frequent resort by the advocates of “creative capitalism” to platitudes (such as: “the world is getting better, but not fast enough and not for everyone”; “today’s miracles of technology only benefit those who can afford them”; “economic demand is not the same as economic need”), along with the vagueness of the term itself, leave me with an uncomfortable feeling.

Although there are other heresies in The General Theory, along with puzzles, opacities, loose ends, confusions, errors, exaggerations, and anachronisms galore, they do not detract from the book's relevance to our present troubles. Economists may have forgotten The General Theory and moved on, but economics has not outgrown it, or the informal mode of argument that it exemplifies, which can illuminate nooks and crannies that are closed to mathematics. Keynes's masterpiece is many things, but "outdated" it is not.
