Useful for early and intermediate level college economics classes, this book introduces those with some knowledge of economics to the larger scientific background of the subject. Specifically, it focuses on economics as a behavioral science, as a political science, a mathematical science, a moral science and finally it looks at the successes and failures of economics and what it portends for the future. Originally published in 1970 by McGraw-Hill, this edition contains an updated appendix and new preface.
