This issue of The Freeman explores the moral and economic principles behind personal responsibility, voluntary exchange, and limited government. It contrasts the virtues of minding one’s own business with the breakdown of reason encouraged by Marx and Freud, and shows how clear thinking depends on recognizing the proper role of premises and logic. Other essays highlight the foundations of Swiss prosperity, the ideological roots of unionism, and the distinction between competitive enterprise and the welfare state. Additional articles defend the language of liberty against socialist misuse, examine aging as an individual right, and reflect on the civic benefits of self-help and just dealing. The issue concludes with a review of Bernard Baruch: The Adventures of a Wall Street Legend.
